Valve lash adjustment on a 5.0L with pedestal rockers

[SuckMeBeeZee]

Good shit man youre one of the few people on here who explains everything step by step.

[346ls6camd]

when you get the lifter before you drop them in you said make sure its pumped up against the ring .. do they come like that new or did you get oil in them? how do you get them to pump all the way up? and once they are pumped up when you are getting rid of valve lash how do you make sure they are not pumping the lifter down when you are torqueing down the rocker? thanks on the input

[BadShoeProductions]

@346ls6camd As said in a statement below, the lifters spring pressure is normally enough to tension the rod cup against the clip. When you torque the rocker down, the valve may open from a tight lifter but don't worry, it will squeeze down against the valve spring pressure.

[stangredemption]

I just want to say that you make the best videos that shows you HOW TO not How to go somewhere else... Great stuff. You deserve a tv spot on SPEED channel

[BadShoeProductions]

@stangredemption Thank you very much.

[stangredemption]

@BadShoeProductions Anytime man, you keep doing this for people all the time and I admire that. It's about time someone took the time and litterally and in plain ENGLISH, step by step tell you pretty much how to check for things and not half way say. not "This is what you do now run to your local shop and tell them to finsh it". I just love this stuff man. If people would watch your stuff, no more local shops... just you

[caperoot]

Ok so if getting this right, u would have to turn the crank a full 360• rotation twice to do all 8 cylinders right?

[BadShoeProductions]

@caperoot That's correct using this method. This makes sure each testing cylinder is on compression and both valves are closed.

[caperoot]

So doing all 8 cylinders you would spin the crank a total of two times around or do you do both cylinders at once: 1&6 then 3&5, 7&4 then 2&8?

[Jeffmtbr]

I can tell from the way your hands shake that you love booze!

[BadShoeProductions]

@Jeffmtbr No, frankly I'm a teetotaler but after 10 years of being in front of a camera, I still get nervous..Ken.

[346ls6camd]

@BadShoeProductions so if you spin the crank 2 full 360 turns you would do both rockers for that particular cylinder correct...or not thanks on input

[BadShoeProductions]

@346ls6camd You can do both rockers for that cyl. at once when your on the compression stroke. No need to turn the crank again for that cyl. When you turn the crank two times, your back where you started from, both valves closed, compression stroke for that cyl.

[346ls6camd]

@BadShoeProductions thanks just wanted to make sure sir nice vid..

[346ls6camd]

@BadShoeProductions do you have to leave new hydraulic lifters in a flooded pan or bucket of oil to get them to pump up? thanks sir..

[BadShoeProductions]

@346ls6camd No, the engine's oil pressure is the only thing that will pump them up. Normally the lifter's spring pressure is enough to verify the lash adjustment as in the video. To check PTV clearance and push rod length, a lifter modded to a solid lifter and an adjustable push rod is needed. The full length Swap vol.1 DVD shows all that info.

[BadShoeProductions]

@vXLiViNGvXvEv1LXv You won't know if you need them until you test the preload as in the video clip. You may need a different length push rod as well. That's why you do this prceedure.

[walter34payton2002]

If you have a roller cam does that mean you have the HO???

[BadShoeProductions]

@walter34payton2002 No, not always.

[saw426]

Should you be able to spin your push rod after 20 lbs? theres not up and sown but i can rotate my push rod.

[BadShoeProductions]

@saw426 Yes

[ksking89]

ok so why is a 91 thunderbird 5.0 timing cover and waterpump different than any other 5.0?

[BadShoeProductions]

@ksking89 The 5.0L 94-95 Mustang and Explorer also use that chain cover.

[muszyngr]

Excellent video, time to digest all your other ones

[MYDRAGGIN84]

Thanks for this i swtich from a oldmobile 2 ford my 1st mechanic exp was a rebuild 302 my friend zero help me become a mechanic im going to school in texas lincoln tech to be a better le jit mechanic there

[bentboybbz]

my 5.0 is supposedly a 93 HO motor...whats the diff???

[BadShoeProductions]

@bentboybbz The adjustment is the same on HO and GT40 heads. The GT40 heads flow better than the HO's.

[VICTOR400HP]

hi, do you know how to identify stock cams, i just buy a 5.0 engine non roller that suppose to has a aftermarket camshaft , but i can see any logo on the back the only thing i can see is a number 21044, is that a stock cam?

[BadShoeProductions]

@VICTOR400HP The number means nothing to me but if you degree the cam and check lift, you should be able to see if it's stock.

[lions66666]

when the valves have been properly adjusted does the rocker when moving ever supposed to come off the pushrod a tad bit or is it supposed to be touching both sides at all times, and if there is supposed to be a little room between the rocker and push rod can you tell me just how mutch space is there supposed to be. and can you also tell me if the rocker is ever supposed to come up off the spring side at all. One more ? when i changed the cam to a larger lift cam do i have to get longer pushrods.

[BadShoeProductions]

@lions66666 Any time you make a change, always recheck pushrod length. After a perload adjustment, the lifter will relax a bit and the rocker may loosen which is normal.

[old5oh]

Hi. I've got a stock 88 5.0 HO.

I am hearing conflicting reports on how much turn is acceptable when torquing after zero lash. When torquing down my stock rockers most of them took about 3/4 of a turn to before 20 ft/lbs. However a few took 1-1/4 turns. To my knowledge every thing in the valve train is factory stock. Should be concerned? Except for a small HG leak, which is why the heads came off, it ran great with noticeable valve noise.

[BadShoeProductions]

@old5oh If it's just a street driven car, you should be fine.

[old5oh]

@BadShoeProductions

Yep, it's a mid 13 second street car. There was a typo in my question, there was no excessive rocker noise previous to the tear down.

Thanks.

[BadShoeProductions]

@old5oh If you race it some, you might try the thinnest rocker shim under the rockers with more than one turn preload.

[old5oh]

@BadShoeProductions

Great, thanks.

[lions66666]

i know this is a dummy question, but my father insists that we dont have to adjust our valve lash cause we have a hdy flat tappet cam and gt40 3 bar heads with pedestal mount roller rockers and that they are self adjusting, i know he's wrong but can you please tell me for shure if he's wrong or not.

[BadShoeProductions]

@lions66666 Your father is correct, pedestal rockers are not adjustable, you can only torque them down tight. And yes, the lifter will keep the lash at zero even as the valvetrain wears. The concern however is when you start changing rockers, cams, heads etc. the lifter may not be able to take up the lash if the pushrod is either too short (rocker will be loose) or too long (lifter plunger bottoms and the valve won't close). Therefore the video clip shows how to verify that the pushrod is okay.

[cacthuptoit]

Thanks for the info I'll try, oh yea what is the right way to break in a new camshaft.

[BadShoeProductions]

@cacthuptoit If it's a roller cam, just start it up and go. If it's a flat Hyd. cam, run engine at 1.5K-2K for 15 mins, then go.

[cacthuptoit]

Hey I have a 351 Windsor I'm installing a new comp cam 512 lif and I'm useing 1.6 roller rocker arm is there a special way to do it or do I just follow the steps you showed.

[BadShoeProductions]

@cacthuptoit Yes, the 351 with pedestal rockers have the same lash checks. However, the complete dvd has much more detail about geometry, push rod length and valve tip contact which should also be checked.

[jessnipe]

hey great video...i have a 1982 mustang GT with the 5.0L H.O and i want to check my valve clearence for exhaust and intake valves it has headers and is ported and polished what should i set the clearence to

[BadShoeProductions]

@jessnipe Just what you see in this clip.

[rcwest1971]

Great video!! Keep 'em coming!! Have you ever heard of swapping a higher lift cam into a 5.0 with stock pedestal rockers and having one or two tick? All lashes were set to 1/2 turn past zero. The wear groove from the lower lift stock cam can cause this correct? I have a bet with somebody ;)

[BadShoeProductions]

@rcwest1971 That might be the cause but frankly, you should be using roller rockers.

[70Ford302]

Ken, my heads on my 302 were milled .010"...the roller tips on my rockers ride slightly to the outboard side of center on the valve tips. Will this be a problem?...I'm using comp pedestal roller rockers (cca-1052-16) with the adjustable pushrod cups which are used to set the preload.

[BadShoeProductions]

@70Ford302 It may indicate the push rod is alittle long which makes sense because the head was cut. If you have a .050" shorter or adjustable push rod, you could check again to see if it makes any pattern difference.

[70Ford302]

@BadShoeProductions thanks for the reply, I did re-check the pattern with an adjustable rod, didn't really seem to make a difference with how these rockers are set up. My question is, do you think anything bad will happen if the tips are slightly off center? My machine shop doesn't seem to think so, but this is going in my daily driver, so I want to make damn sure! haha!...I'll post a video with the rockers i'm using.

[BadShoeProductions]

@70Ford302 It will likely be fine for a daily driver.

[MUSTANGVERDE]

Great video ! Kill all my doubts !

If I need to shim the pedestal roller rockers , can I use regular washers? I haven't access to a shim kit here ...

[BadShoeProductions]

No, you really need to use shims made for that purpose.

[BadShoeProductions]

Try to get it as close to 90* as you can however, the valves will still be closed a few degrees before and after TDC compression stroke. Therefore the lash check will be correct for that cylinder.

[pimponcito2]

i have to turn the crankshaft in each cylinder to install the rockers?

[BadShoeProductions]

Yes, if you want to verify the lash on each cylinder as each one very be just a bit different.

[ourobos]

I have your 8.8 and T5 videos, always good info, thanks Ken.

[89stanghondaslayer]

Did anyone notice that the passenger side head is a gt40p head "ford explorer head" and the driver side is just a regular 5.0 head?

[BadShoeProductions]

Both heads are GT40P units. If you look close through the whole clip, you can easily see the 4 bars on both heads.

[89stanghondaslayer]

Yeah I see that now lol i couldn't see it that great!

[BadShoeProductions]

Of course all rockers need to be checked individually which is why I show how to bring up all the cylinders to compression stroke. Stamped rockers leave such a wide contact patch on the valve head that moving the rocker on it's slot won't be much value but rollers might be helped somewhat. Fact is, pedestal rockers are not adjustable other than use of shims which should kept to a max. of .090". Therefore with pedestals, having the correct lash is the most important concern. DVD set has details.

[BadShoeProductions]

This is true and if you watch the being of the clip you will see a note saying that pushrod length and valvetrain geometry was checked and detailed earlier in the complete 4 hour DVD. This short clip verifies that the lifter preload or "lash" is correct for the pushrod selected.

[williamsportwrestler]

Hey ken! I was on your website today and was wondering if in the future there may be a windsor rebuild video I would be very interested in this along with several others I'm sure. The reason I am asking is because I am ready to get my hands dirty and I don't do well with reading then doing. It's so much better when you have a professional show you. Unfortunately I have no one to show me or help. I plan to buy your c6 video this winter so I can freshin up my tired trans thanks for everything!

[BadShoeProductions]

No plans for a 5.8L build at this time however my 5.0L swap video has lots of info on checking normal engine component wear, camshaft, valve spring installation, checking rocker arm geometry and torqueing torque-to-yield head bolts all of which can apply to the 5.8L. as well.

[natemcclure]

thank u for all that i was wondering i have a ford 429 and i have a cam kit its the 292h hydrolic flat cam would i be able to run pump gas with it thank u

[BadShoeProductions]

I have no idea, not enough info. If you are using pump gas now, you should be able to use it after a cam change. If your adding a supercharger with 20 psi of boost along with this cam, then pump gas may be a problem.

[ezsautomotive]

Very informative...thanks!
