Chevy 5.7L 350 ticking/knocking

[ArkansasMudder725]

my truck made tha same noise and it turned i had a hole in my header

[texasbadboyz105]

sounds like a exhaust leak. Use a rubber hose and hear through it around the exhaust and it will sound through the hose and you will find ur problem

[cattjamm]

i have a 95 chevy with 350 5.7L with 243000 miles an it made the same ticking noise an it was one of my rollers

[themadmek01]

if you have not figured this out yet it is an exhaust manifold leak. replace the gaskets and you are golden.

[pugz74]

put slick 50 in it

[drippinblood28]

lifters?

[silicon212]

Sounds like an exhaust leak. Most likely EGR valve gaskets or a loose intake.

[seapeddler]

When Chev makes a V8 like the Camaro V6 with integral exhaust manifolds in the head, it will be a good engine. Safety wire on exhaust manifold fasteners is a good idea. I suppose you just drill holes in the bolt heads and thread it around somehow. Clips and the like can go missing.

[scrimmy6969]

exhaust leak..

[matthew50673]

take valve cover off and check liftersto see if tight

[cnmtires]

foo chek the exaust gasket.......

[HiTechOilCo]

The best oil and filters wouldn't need changing every 3,000 miles. The noise you mention does sound like an exhaust leak.

[FHFCFB100]

Stp and rxp stopped mine

[91dwjohns]

it could be several different things luckily a 350 is cheap to fix it really sounds like the valves are out of time

[Usernameinvalid16]

Adjust your Valves Thats all it is. They are to Lose causing a Clicking Tapping sound.

[ChantryBoys]

we have a 99 yukon with 5.7 vortec it is knocking now which is the connect rod but sounds like you might have a whole in ur manifold or bad plugs and wires

[rileyjr16]

Mine had 234k when I sold it and my dad has 365k on same engine, trans when his started knocking. Pretty pissed cash for clunkers got old blue.

[rileyjr16]

I love them old trucks

[Deciblaster]

Does it stumble under load? or is it just a wierd noise your hearing when running it?

[RandomZcar]

@SolovinoHD That opening is just for an air tube to help direct air from your air cleaner, its fine being open

[D4nn1Prid3202]

Radios not working

[mjr102395]

just crank up the radio. That should solve your problem.. Your welcome in advance...

If that fails. Buy a FORD

[mikester9er]

@mjr102395 I think he wants less problems, not more.

[dunn98632]

Its a exhaust leak change your exhaust mandifold gaskets if you want it won't hurting anything if you dont.

[wandareager]

sounds like an exhaust leak i have three of those trucks and two have exhaust leaks and sound the same

[TractorWorld]

could be your wristpin on ur piston!

[bjboge23]

yes exhaust leak my 1994 chevy 350 makes the same sound and the leak comes right off the heads

[antwian19]

Nice motor dude

[SolovinoHD]

At 2:43 Why do you have that opening on your engine? I have it to! Its my first car, I know nothing about mechanics, Is that opening suppose to be like that or is something missing? and if so, what ? :O

[hurleyhat15]

sounds like an exaust leak bud

[JuicinaPeach]

@xboxisbeast. If he bought a ford it would be a scrap pile by 240,000. Worthless fords

[kaingriz]

my 77 heavy half does this....missing an exhaust bolt and the exaust is all messed up. jsut sounds sketchy....no harm

[xboxisbeast101]

its a chevy get rid ov it and get a ford

[smokey65662]

@xboxisbeast101 We have one of those. Works just as well as the truck you see here. Its not like buying a ford is going to magically fix all my problems. It will break sooner or later, just like every other vehicle.

[halo3oneshotsniper]

@xboxisbeast101 wow thats the tell tale sign of a Ford fanboy if ive ever seen one...

[Usernameinvalid16]

@xboxisbeast101 Why so they can have More Problems???

[bigpaw64]

loose rocker arm----for sure

[daddytech]

you need a valve adjustment. and possibly the way it sounds a new set of donut gaskets for your exhaust manifolds too but before you do all of that how about running some seafoam through it by the vacuum line from your power brake booster just in case it's just a plugged up catalytic converter.

[elmore1864]

tu puta chingadero no sirve se aoga la putado ade mas prende muy ahuevo jajaja

[mharrop396]

u stole my thunder corvette george...

[Vintagesansui800]

My 93 was just making a noise similar to this but a constant noise. turned out to be a loose crank pulley.

[1dogeez]

/egr check replace temp switch i hav the same prob

[1dogeez]

/egr check replace temp switch

[TroyBoy4201]

my 94 made the same noise, it was caused by a rusted out y pipe where it bolts to the exhaust manifold.

[DRNEGOLICIS]

Either exhuast leak or lifter tap use 40W oil or 50W and add lucus oil additive it does wonders

[scott93257]

Good ol 350...One of the best engines GM ever built...Glad you figured out the problem and it being so simple @ that

[Bjorn37]

I have the same engine in my 93 truck, and i was wondering how to adjust the timing. I had to replace the distributor and since then i hasnt been running right and i know it has ho be that the timing is off but i dont know how to correct it with this type of distributor? If anyone knows send me a message thanks

[watso64]

Deff, Exhaust leak, If It was a rod knock, the engine would make a noticeable knock even at idle. Also to be on the safe side with it having high miles, I would recommend you check your oil levels every week at keep at least a quart in the truck at all times.{esp pulling loads}

[smokey65662]

@watso64

Surprisingly it doesn't burn any oil for all those miles. This motor gets run very hard pulling loads or just having fun and I have never noticed a problem. I believe most of that's just from taking good care of it, like using WIK over sized oil filters, and royal purple oil, frequent tune ups, etc. I did get it fixed though (was an exhaust gasket leak).

[watso64]

@smokey65662 WOW no oil consumption, pretty suprising, course it is a 350{one of GM best engines} but still surpising esp with that being towing miles. Proves strict maintenance pays off. Glad you got it fixed.

[tss212]

@smokey65662 Wix filters lol

[smokey65662]

@tss212 Better than the trash you can buy at wal-mart.

[josh666675]

@watso64 It's a exhaust leak for sure. My truck has the same and it's so annoying Haven't got to it.

[josh666675]

@watso64 I have thesame knock I bought headers to get rid of this BS exhaust manifolds and throwing headers on. I'm hoping it's the exhuast leak on mine

[corvettegeorge79]

Sounds to me like exhaust check manifold to pipe on drivers side. Engine torques and connection may loosen maybe bad motor mount. Sounds like it runs good for that many miles.

[smokey65662]

@corvettegeorge79 Yes u are right. We had it checked out today, and it was a bad exhaust gasket on the drivers side rear cylinder. It does run pretty good. Always taken good care of it.

[UBBERTANKER]

sound like a leaking exhaust manifold/header to me not inside the engine

[09moodye]

is youre exaust manifold or headers witchever you have loose cause that happend to my 1984 chevy scottsdale
