Valve Lash Adjustment Video - Engine Building Car Repair DVD

[STRYKARLITE]

When I was in auto shop classes in high school in the late 1970's, my teacher taught me how to memorize the firing order of an inline 6cyl. chevy engine...(Too young, Too old, Just right) 15 36 24

[canthony1019]

@STRYKARLITE every motor is different.....

[zeppelin67637]

@STRYKARLITE haha I like it

[donell213]

perfect description

[rick8758]

This video was very helpful as I am doing a complete rebuild on my very first egine unassisted.. Thanks

[jonnham]

I got this dvd from a mentor. It is a good one, but It does not offer any explaination of these components or what they do which is what I need. I think you should know something about automotive engines before hand. But it is a good dvd otherwise

[grkstd1967]

if u over tighten the valve by 1/4 turn will that affect the timing at all,,thanks

[zeeconstructions]

effects of engin change on the transmition? i changed my diesel 2400 engin with 2400 petrol engin but kept the transmission same .on my mitsubishi pajero 88 three door ..

[jayr122001]

how much does it cost to replace a broken valve in nissan altima 1998 model ?

[jayr122001]

how much does it cost to replace a broken valve ?

[cranemaster844]

"rotate the engine about a quarter turn" (for the next cylinder on a V8)

"you'll only have to rotate the engine once"

Math?

[mig8830]

@cranemaster844

2 turns of the crank is 1 turn of the cam.

[TheGazdik]

so if im thinking right, you adjust to zero lash then give it another half turn?

[SchizoFilms]

So, what about Overhead Camshafts?

[Psi4tsi]

@SchizoFilms theres no pushrods in an OHC engine. The Camshaft itself is was opens the valves.

[SchizoFilms]

@Psi4tsi Whoop, need to stop posting late at night. Sorry bout that. I have an OHV in the truck and an OHC in the car, and since I'm always working on both of 'em (and they both have misfiring cylinder(s)) I tend to switcheroo.

[rcfirdy]

Finding this "zero lash" position by feel is influenced by too many variables which allows a degree of inconsistancy.I'll pass on a tip that was shown to me by Barry Seton in 1985.Adjust the valve clearance to 5 thou.,then turn the the rocker nut down 3/4 of a turn.Thank you for reading.

[BoxWrench]

@jujutube123 This is the correct procedure for taking a hydraulic lifer to zero lash and then adding the required pre-load to the lifter. The pre-load is set by turning the rocker nut down the extra half turn after reaching zero lash.

With solid lifters, you go to zero lash with a specific feeler gauge between the valve tip and the rocker. For hydraulic lifters, you need to do the procedure described here, including the extra half turn.

[grkstd1967]

is the diagram at 2;48 the same as a chevy 350

[lakeboy36111]

hey great video, im just wondering how to get the zero lash with both valves closed with the intake manifold on without being able to see the lifters. Im guessing its aot harder to eyeball where the rockers are sitting? I just had one head done on a older chev 350. Not too sure.

[BoxWrench]

@lakeboy36111 This is only a short sample clip from a 3 hour DVD.

The full length version shows you how to adjust the lash when the intake is installed.

It's pretty simple. The pushrods are still going to be reachable just above the cylinder heads and below the rockers. You can roll them in your fingers there, instead of in the lifter valley.

[truckdropper]

@BoxWrench good video, but I did it like hoe you explain and it was too tight engine would even run i ended up doing it as the engine runs loosen the nut untill rocker chatters then tighten it till it stops chattering then an extra 1/4 turn. runs real smooth now.

[tazztt1]

@lakeboy36111 ...

1 - note #1 plug wire position and pull the distributor cap,

2 - rotate the engine to #1 TDC (rotor @#1 and timing mark on balancer @0deg,

3 - adjust i&e rockers to 0 lash then add 1/2 turn,

4 - rotate the crank 1/4 turn (90 deg) and watch for the #8 i rocker to drop and stop then adj i&e rockwers to 0 lash then add 1/2 turn,

5 - repeat and adjust cylinders 4-3-6-5-7 and 2, in that order. You will only have to rotate the crank a total of 630 deg (1-3/4 turns).

[tiffanyjames45]

Heres the i have done it for years. get the motor to top dead center firing on no. 1. adjust both valves to zero lash then go 5/8 of a turn more. Then adjust the intake on no. 2,5 and 7 cyclinders. then adjust exhaust on 3,4 and 8. Then turn the crank 360 degrees, now your on no. 6 adjust both valves, then do exhaust on 2,5 and 7 then intake on 3,4 and 8 . Install the valve covers and your done. this is for chevy small and big block with hydralic lifters.

[StealthNinjaX2]

my engine makes a clicking noise when cold, i think my valves need to be adjusted, what problems can occur if i dont adjust right away?

[BoxWrench]

@StealthNinjaX2 If you have hydraulic lifters, in the short term it will just be the annoyance of the chattering rockers and you're valves will be a couple thousandths of an inch shy of fully opening (but not always).

In the long term, you'll begin to wear out the matting surfaces of where the rockers meet the valves or where the cam lobes meet the valves... depending on what type of valve train design you have.

[StealthNinjaX2]

@BoxWrench thanks for the reply bro

[mitszamitaz]

@BoxWrench Hi! what if i hear valve noise after the engine of my 2000 Cherokee warms up?(I just replaced the head gasket,p roads etc were numbered.) I would appreciate your answ. since i am getting tired of neighbors/toyota owners giving me crap! thanx! Mat

[RicerEater1978]

spinning the pushrod never works. when i put motors together, i run them at idle without the valve covers, tighten the rocker until it stops clicking, then a quarter of a turn more

[Enginebuildup]

Hey Fullmet31, From what your saying here i think that it is possible that you have posi locks that are used for adjusting rockers, inside there is an hex screw that locks the nut so it soes not come undone, loosen that of first then try turning the adjusting nut. although, if you getting a quarter turn preload, and there is already oil in your lifters you are already at where they need to be. Theres is no need to adjust any further. Hope this helps

[Duddie82]

I bought a 1978 Camaro with a 350 engine, But with a 2 barrel carb setup, Once I removed the 2 barrel carb and intake, i noticed two push rods extremely loose. Before removing the 2 barrel setup, I marked the timing, s. So I am thinking I will need to remove the Valve cover and tighten the two loose push rods.. Is that going to work? Of course, it was easier to work on that with the intake off, but that was not possible, I will need to make sure those cylinders are on Compression mode.

[worldofwheelsdm]

Not every used car dealer is trustworthy. For trusted used car dealers visit the World of Wheels in Des Moines.

[Fullmet3l]

I have Crane Cams roller rockers in my 1991 5.0. I can get it so the valve lash is adjusted good, but when i go to set lifter pre-load i can only turn 1/4 before the bolt gets very hard to turn, and its pretty much rock hard.

[Enginebuildup]

@Fullmet3l you probably have posi locks that lock the adjusting nut to the rocker stud. There is a hex screw inside the nut that will need to be loosened by holding the adjusting nut and using a allen wrench to loosen the hex screw that is inside the nut. Then you will be able to get the required half turn preload. Take note though, some builders prefer to run the engines with just 1/4 turn preload, It is said that there is power to be gained from this however i am yet to ever see proof of this.

[johnyjoe2k]

Wow, great vid! Do you guys do Inlines? Would love to see some BoxWrench vids on imported engines like Inline 4's and 6's or boxer engines.

[BoxWrench]

@jujutube123 With solid lifters, you stop turning at 'zero lash' with the correct feeler gauge installed.

With hydraulic lifers (roller or flat tappet) you set to 'zero lash' and then add at least a half turn more. Some engines even require a bit more.

You may notice the valve open slightly, but as the pressure inside the lifter bleeds off, the valve will return to it's seat.

This is all covered in detail in the 3 hours long 'Basic Engine Building' DVD

[tabletop45]

so even with non adjustable rockers, you still want to make sure that the piston you are working on is on its TDC?

[BoxWrench]

@tabletop45 it is best for you to set each cylinder at TDC to tighten even non-adjustable rocker stud type cylinder heads.

some engines have a lash tightening sequence that you can follow to minimize the rotations of the engine in order to preserve the moly lube on the camshaft.

[blueyourk1]

wow

[brakedd]

does all of this apply to late model (1990) small block ford adjustment as well? its a roller motor

[BoxWrench]

@brakedd this does apply to roller lifter engine designs as well...as long as they have hydraulic lifters

[Nate01R6]

Very helpful! Thanks guys!

[aBlascakProduction]

will the actual rocker be able to move a little after the half turn, or will it be tight enough to not move around on the stud?

[BoxWrench]

@aBlascakProduction the rocker will possibly move just a bit but it will feel tight.

The pushrod will not move after the initial extra turn, but when any pressure bleeds off inside the lifter and after a few rotations of the engine, the pushrod with spin slightly when the cam lobe is at bottom and the valve is closed. But as soon as the valve starts to open, the pushrod will firm up and will not be able to spin in your fingertips.

[cacthuptoit]

Hey nice video, i was wondering if this is the same for a 351 windsor I'm installing a comp cam 512 exhaust lift and I am useing 1.6 roller rocker arms

[BoxWrench]

@cacthuptoit if you have hydraulic lifters, yes this is the procedure.

[nicksare]

fords and chevys have different firing orders so they in fact wouldn't be the same ?

[BoxWrench]

@nicksare If you watch again and pay attention to what is said, you'll realize that we are giving generalized instructions for all types of engine owners to use.

The firing order and procedure shown is for small block Chevy, but the instructions say to follow your specific firing order associated with your engine type.

With this video, and the engine specs for your block (American V8 engine specs are available at our website) you can perform the same procedure on Ford, Chevy or any other...

[saw426]

Hi , i just changed my lower intake gaskets and checked out the push rods , im able to spin them with my fingers but theres no up and down play in the push rod , should they be spinning like that ?

[BoxWrench]

@saw426 Yes, any of the valves that are in the closed position will allow you to spin the pushrods in your fingers, but you'll have no up and don't slack if the lash is set properly on a hydraulic lifter.

Any of the valves that are open or being held open at all by a camshaft lobe will be too tight in the rocker arm to spin with your fingers.

[BoxWrench]

@sschevypwrbb You may be ok, but it's a better idea to go back through and do the proper lash adjustment.

The tell tale sign with be if you have a chattering sounding top end. If your valves are all clacking away at the rockers, you should redo the lash adjustment.

[BoxWrench]

@jujutube123

The half turn is fine for an average 'hydraulic' lifter. It may seem like too much if the valve begins to open just a bit... but if you put a dial indicator on the tip of the valve, add the half turn and watch the valve open...in a couple minutes the pressure will bleed off in the lifter and the valve will return to it's seat.

Pretty much all hydraulic lifters behave this way.

[ts46176]

sample clip? i pulled my valve covers off my chevy 4.3 and did exactly what the video showed, went from sounding like its going to blow up to being so quiet you can barely hear it running, if this is just a sample what else could be involved? seems pretty complete to me, hope it is anyway lol

[BoxWrench]

@ts46176 yup, this is just a 'sample clip'.

this is a 3 minute excerpt from a full length DVD that is over 3 hours long.

'Basic Engine Building' shows complete teardown, machine shop procedures, pre-assembly, final sealing and assembly as well as start-up guidelines...

If you're actually going to tinker with any kind of piston engine, it's worth checking out.

Thanks for watching the sample though... Glad it was helpful

[jasonz28camaro]

so can you adjust both rockers for each cylinder at the point in the video where you only did the intake?

[BoxWrench]

@jasonz28camaro Being able to adjust both valves at the point when the intake closes depends on the type of camshaft you have.

In most stock engines with a factory installed 'low-profile' cam, it is safe to adjust both the intake and exhaust at TDC for the particular cylinder. When you have a high performance camshaft, the opening and closing events of the cam lobes are more radical and you need to adjust according to the cam manufacturers specs.

[krisantuzzi]

Thanks for this video. Im putting my fiero engine back in and just put the new heads on. This video was a huge help.

[MUSTANGMAN50LX]

thanks man i'm about to do that to mine stang

[BoxWrench]

@StanMangler

We're glad you found the 'Valve Lash' video portion sample here on YouTube helpful.

The clip on YT is just a sample from our full length 'Basic Engine Building' DVD.

Let us know if you still had questions after watching the sample clip. There is a lot more information in the complete DVD but we're interested in whether the sample clip alone is helpful enough to get the job done for other applications other than the ones shown.

[BoxWrench]

That's correct, you want to add a zinc additive to modern engine oil when you are using a flat tappet camshaft and lifters set.

[scibaer1]

so, if i hear this right, the lifters do not have any motor oil in them, when you lash the valves ?

as in a new cam and lifter set ? or should i soak the lifters and fill them with oil ?

[BoxWrench]

soaking the lifters in oil will allow them to pump up a bit quicker but is not a requirement.

As soon as oil pressure builds, a set of new lifters will fill quickly under oil pressure and begin to send oil up the pushrods.

[gunnabefamous]

Underhead Cam This seems like such old tech Nowa days Ohc so much easier to maintain'

[ThePurpleGang]

Are you kidding? OHV engines are wayyy more simple than OHC, especially since most of them now have DOHC. I only have to deal with 1 cam and 1 timing chain in mt SB Chevy, instead of 4 cams and 2 chains in new engines. Nothing is ever made simpler with time.

[BoxWrench]

Not so much 'new tech vs. old tech' as it is 'different technology'.

There are hundreds of thousands of people out there that own and enjoy wrenching on classics and even recent engines that have "in-block" camshafts.

OHC designs are just a standard for an entirely different type of engine design, and vehicle application.

It's a comparison of apples and oranges, you should just respect each for their various designs and applications.

[maxestuardo]

I just turn up my radio so I dont hear the noise. simple

[chevyluvsmusic]

@jujutube123

[DeanMLFlame]

nope...comp cams does recomend 1/2 to 3/4 turn

[zztops08]

Dose any of this change with roller rockers? any different steps?

[72fordmaverick]

what does the rotation look like for a 250 CI straight six???any idea?got some valves and rods that need adjusting.

[ktmboy1989]

you rotate the engine an eighth of a turn to get to the next valve right not a quarter, right?

[67f850]

No it is 90 degrees it takes 720 degrees of crank rotation to go through firing order divided by 8 cyl equals 90 degrees .crank rotates two revolutions per one revolution of cam

[wayne007nz]

ktmboy is correct, you can set all valves with only 2 rotations of the engine, this saves the cam lobs and bigend bearings in a total engine rebuild.

[67f850]

2 rotations =720 degrees divided by 8 cyl means 90 degree rotation per cyl adjusted.

[BoxWrench]

@ktmboy1989 amount of rotation to get to the next cylinder is directly related to the type of engine and crankshaft. The degrees of rotation of a 4 cylinder crankshaft tied to one of two overhead cams compared to an 8 cylinder crankshaft connected to a single cam will be completely unrelated. That's why you look at the valves and their opening events to determine TDC for each cylinder. Only the #1 cylinder is timed to the mark on the balancer/timing cover

[67Stallion]

@ktmboy1989 A quarter turn is correct, since the crank rotates twice to complete a full firing order. The camshaft rotates at half-crank speed, so 1/4 crank turn = 1/8 cam turn = next piston tdc firing.

[BoxWrench]

@ktmboy1989 don't determine the valve opening events by rotating the crank only.

You should watch the pushrods, rockers or lifters to determine when the valves are actually opening.

If you want to adjust lash on an engine that has the heads bolted in place already...just remove the valve covers and you can watch the pushrod ends and valve tips as the opening and closing events happen.

[tazztt1]

@ktmboy1989 ... 90 degrees or 1/4 turn for each following cylinders... the crank must be turned twice for each one full revolution of the cam

[Th3C0ol1]

I remember in class one of my friends dropped a valve keeper (on sohc 92 honda). We looked for it for days! And without the right tool those are a pain to install.

[jacktheripped]

correction to my first post, the rails are to keep the rockers from squirming around on the valve, you can't really see them on the rockers in the video but they are there. And I'll also bet you have to grind the tip of the valves to remove them as they have mushroomed and will not fit through the valve guides anymore, don't force them or your guides will be ruined, too.

This is a very bad situation, get it fixed if you haven't already.

[71bee383]

This is an easier procedure with a Chrysler big block engine. I like how MoPar used a rocker shaft, rather than the individual rocker mounts.

[slant6guy]

Thanks for having this video here! I with my brother's help am rebuilding a 1980's slant6 in a Dodge D150 shortbed (it's on Wikipedia) and this was a holdup besides the weather here in Alaska in getting the truck back on the road. I learned a lot with this video. THANKS!

[pantherxx010]

hey I used to have a duster 73 that had a slant6 until my parents sold it without asking me I was PISSED! Anyhow those slant6 have hell alot of torque than horsepower.

[PIMPGOLD69]

really great videos. i have adjustable rockers and hydraulic lifters. When i find the closing event for #1, do I adjust BOTH the intake an exhaust lash at that time? or only the intake then repeat whole procedure for exhausts?

thx

[frostbaracudas]

if the rockers are not adjusted what happens? i mean is there any specific sound you can hear and understand that?

[BoxWrench]

Hydraulic lifters in combination with rockers are adjusted with too much slack will "chatter" when running. This clacking-chatting noise will be more severe when there is more slack and will be heard coming from under the valve covers as the sounds are created by the slack between the rockers tips and the valve tips as the lifters push and then relax tension on the pushrods.

Engines with solid lifters need to keep a bit of clearance between the rockers and valve tips because of heat expansion.

[Deafpowerful4x4]

how it wud be chatter when running during adjust the value???

[BoxWrench]

Do you mean, how can you hear the chatter while the engine is running...? You would notice it even with the hood closed.

[19LivetoDrive80]

You guys have some great vids! I have a 67 Mustang with a 302 out of a later model. It has aluminum heads and roller rockers, and Im having a problem with the roller tips being too far to the side of the valve stems, and some of them are close to rolling off the sides. How can I correct this? Thanks for the help

[BoxWrench]

Your pushrods are too long.

Replacement pushrods can be found in different length increments of .050".

Figure out what length will give you the correct roller tip positioning on one of the valves and but a set of pushrods at that length.

[BoxWrench]

By the way...My reply above that your pushrods are too long is based on my assumption that your roller rocker tips are getting close to rolling off of the valve tip side that is closest to the outside of the engine (the exhaust exit side of the head).

If your pushrods are too short, the the roller tips would be closer to the intake manifold side of the valve tips.

[19LivetoDrive80]

Thanks for the help! But... the roller tips aren't rolling off the intake manifold or exhaust side of the valve tips, its side to side, or from firewall to engine fan. Any ideas? Thanks again

[jacktheripped]

you either don't have guide plates or some Ford rockers have giude rails on either side of the rocker contact point to keep the valve from squirming around. If these are after market rollers then the previous owner got the wrong rocker arms and there is nothing to keep your rocker arms square to the valve stem and youe wearing your pushrods out badly. DO NOT RUN THIS ENGINE ANY MORE!! your heading for MAJOR head rebuild if you do

[jacktheripped]

damned youtube, this is an answer to 19LivetoDrive80. and I also see that you posted 2 months ago. you still running this motor? I'll bet you can visibily see that your puchrods are getting concave where they rub the cylinder head plus your oil filter is full of metal shavings and the ingested metal has worn your oil pump badly. Don't Run This Motor Any More until you get this fixed. You will likely have to replace your pushropds, rockers, and oil pump, clean the pan and pick up tube too.

[818CHEVYVALLEY]

Good video. I am about to adjust my 350s rocker arms that i rebuilt. and before i put the oil pan and heads i left the engine with piston #1 in TDC. So would that mean I can tighten up cylinder 1 rocker arms and then go on through the firing order.

[BoxWrench]

You would only know if you were on the actual TDC for #1 cylinder if you had the heads, valve train + rocker arm installed and were looking for the valve events as described in this video (or the follow up of the Final Assembly of cylinder heads in our DVD). When you're at #1 cylinder closing event of the intake lifter for #1 cylinder (stock camshafts only) you can then adjust the valve lash to "zero" for the #1 intake, add the extra half turn and follow through along the firing order.

[818CHEVYVALLEY]

Oh i get it now. So i will have to rotate engine again till i see cylinder #1 close then adjust the rocker arms right and then so on throughout the firing order. Am I correct. I thought it would of been top dead center since i had centered both timing gears i guess i was wrong. Thanx for your good video and your help :).

[BoxWrench]

Pretty much yes, as you described.

You're looking for the closing event of the #1 intake valve though, not the cylinder itself. The cylinder comes up twice through the four strokes, once for compression and the next time for the exhaust stoke, then repeats.

With no timing cover in place you'd be able to line up the timing marks and adjust the #1 cylinder only. Then you'd have to determine the closing events of each of the other cylinders to properly adjust them, just follow the firing order.

[not4viewing]

thanks for the informative video..do you have any idea where i can get or buy a full dvd version of your vid or any informative videos regarding automotive mechanics from engine,starting system,ignition system,fuel system,lubricating system,cooling system, auto electrical system that includes charging and lighting system.power train or drive train system,underchassis that includes suspension,steering and breaking system? i live in queens NY. thanks.

Thanks for posting!

[TrojanHorseXX]

Thanks thats very usefull

[TrojanHorseXX]

what about the feeler guage? don't you need to follow spec's for at least .001 clearnce?

[BoxWrench]

You only need to use a feeler gauge between the rocker tip and valve tip when doing lash on an engine that has Solid Lifters.

The majority of engines these days have Hydraulic Lifters that run much more quietly. You set some "pre-load" on the lifters and then oil pressure builds up in the lifter and keeps pressure against the rocker to keep it from chattering while the engine runs.

Solid (Mechanical) Lifters generally are a bit chattery sounding, but you do need to run them with clearances.

[blueoval331]

these guys are very imformative.

[gasserized]

Hey 4 pots have come ON quik with new designs etc ,no doubt about it but v8s sound much nicer than screaming 4pots and beetle motors ,im not saying there quicker but if i wanted my car to sound like a motorbike every time i fired it up i think id be sick..

[shaftiee]

ther r some nice soundin 4 cilynder engines too u know, like honda's v-tec engines, but v8's do sound better tho, specialy at idle, lol

[danielcev]

jajajaja esos motores ya no existen y dudo mucho que vuelvan a hacerlos... pero interesante el video...!!

[fordxtreme2]

you're videos are amazing!

[suxnitromax]

i allways adjust them like this bloke, but then i do them again when the engine is running,if you want them adjusted right you should do them when the engine is running,also ive found that you get more horsepower when there left loose due to overlap if you need any help with engines give me a yell and ill be happy to help

[lerlo]

LOL at pushrod, come on america, get with the times!!

[Augusto1963]

why are you laughing? don't you know that STOCK LS7 PUSHROD corvette engines make 620 horse power? and stock Viper engines make 600 hp? take that up to date 4 cammed ferrari engines...lol

[lerlo]

Lol, and whats the capacity of those engines.

[komokaziboschetti]

meh, they have a whole lot of potential for HUGE power without the need of gigantic turbos that need the engine nearly redlining to make full spool.

[kempobrad]

i think its good to go with what you have, especially on a limited budget. but a bone stock factory 350 chevy small block makes much more power than a hopped up naturally aspirated 4 cylinder ever could. to equal the power of a stock 350, you'd have a hard time driving your small cube 4 cylinder on pump gas on the street. probably couldnt run power brakes...and a whole bunch of other things. small motors need alot of rpm's to make power. to keep them drivable...you need turbo or nos.

[nwman7]

hey guys where is the love. Just respect any well made car or motor

[wyteboymagik]

agreed, i'm not a big import fan or ford fan for that matter, but i give much respect to anybody putting some wrench time on their rides

[redxpen]

o rly guys? i hate domestics. its not the horsepower of the car, its the power/weight, torque/weight, and power/liter ratios. i bet that your 350 will b pretty close to alot of 4 cyl on these ratios. IMPORTS, ride til i die

[kempobrad]

i'm just saying a 350 can make the same amount of power alot easier. which is true of any engine. bigger cubes makes more power more efficiently. on a budget, you can hop up a 4 banger and still be challenged by a v8. even in imports, more cubes tends to = more power.

[redwalsh87]

Older engines (aka pushrod engines) are what need to be rebuilt. This is probably why this is what this video series focuses on...

[lerlo]

nah i just said that to piss off v8 lovers

[redwalsh87]

Yea well my pushrod 302 V8 will take on any stupid 4 cylinder you have over there in singapore. Go make some rice or something...

[lerlo]

Believe what you wanna believe dude, but Im saving sooooo much more money on gas than you. Truth is it takes more skill making a 1.6 litre push 160 hp than your V8 POS. Lol, LOSER

[trimox]

have fun driving anything with 160 hp...lol

[lerlo]

More fun than your POS thats for sure, lol

[lerlo]

Americans support V8s because they make them, I perfectly understand that. But why do you have to call every import driver a ricer, and put them down so bad? And then again, you guys have one of the biggest import scenes. You dont see many american muscles in Japan or many parts of world, this just goes to show what the world thinks of your cars. Im currently in Australia and Ive driven V8s, they are proud of V8s as well, but they dont look down on imports like the Americans.

[chevydually454]

lerlo, What do you think a Holden is? It's a Chevrolet with a slightly different skin. They are GM. As for this video, great job, keep them coming.

[theginacologist]

...just stop.

[berxout]

you speak wise my friend...

[RyukoTR]

i have that same torque wrench

[doesitmatter1920]

I am craving car knowledge ...but this stuff seems a little to complex i need a starting point or something

[cantread00]

start with something basic like how an engine works this isnt really a good video for somebody who doesnt know to much about a cars internals

[Bassplayingboy]

How do I determine if my lifters are bad or the rocker arms need ajusting? The enginer is a 2.9L V six 200k mile and nothing has been done to the engine. I hear some ticking sometimes when the engine is cold then it goes away. It is expecially bad if the truck has not been run for a few days. The oil pressure is OK and the lifters are hydolic. I put some heavier oil in the engine and seems to help. Will I need to adjust the rockers after lifter replace?

Shane

[woodington1]

what you all need to do is contact me for valve adjustment procedures ,as i have the way,and the terminology that beats ALL others

[BoxWrench]

Post a video...we'd love to see others share their expertise. We'll even add it as a favorite on our channel.

[Thrasher502]

wow... this is very informational

[isTHATaHEMI]

what kind of valve train would the 350 L98 out of a trans am have ?? anyone know?

you have a hydraulic lifter valve train.

Spin your pushrods until you can't spin them freely anymore. If you have an 86 or newer Trans-am you will have a roller cam and roller rockers, so valve train damage wont be an issue, since the goverment has taken the old ZDDP levels of lubricant out for the old Flat tappet cams.

if I were you and I had a stock L98 out of a 86+ Trans am. I'd look for an LT1 cam and headers.

just my .02

yeah i might just go ahead and do that or i might just go and save up some money and get new heads and new valve train but thanks for the advice

you can start the engine up with special made valve pans. run it and not have oil spray on you. and really hear if the engine has a few backed off

How about using the GM nethod of #1 at TDC compression stroke and adjust half the valves and then #6 at TDC compression stoke and adjust the other half? As listed in the GM factory service manual. This works well and a lot less trouble.

The lash adjustment method shown here is the only way to cover all bases with multiple make of engines. A GM manual may only apply to a select number of years and cam specs using the #1 TDC and #6 TDC lash adjust method. Our DVDs consider all engine makes and types (including 4 cylinder and 6 cylinder models) and shows a valve lash method that can be used for all engine types.

For many GM blocks though, the #1-#6 method works well.
