Valve Cover Questions

[Afizzle]

i am about to replace my little bros vc because he has a crack in his and its purging during a boost leak test.

the vc he bought had a part of the metal inside shaking around. it looks like all the way around it is pinned down but at this end the pins dont go through the metal and it shakes around. will this create a problem after installation? also as you can see the vc is kinda dirty in there. we have run it through a parts washer and hand washed it and still have some dirt/rust mixture on the inside. it isnt like super heavy but i can rub it with my finger and it stay on my finger.

what do you guys think about this valve cover? we dont want any contaminants in the motor and dont want any rattling from the vc

also on the install: new vc cover and spark plug well gaskets, RTV the 90 degree angles and thats it correct?

That is the baffling. You can use jb weld to hold it down or drill and tap to put screws in there with red loctite. Or you could opt for the CompWorks aluminum baffles and have them welded in. You cannot weld the steel baffles to the aluminum valve cover though.

Yes, just a tad of rtv in the corners is all you need. Finger tighten the bolts and then go half a turn with a rachet, do not crank down on it or the valve cover will likely crack again.

If you have a torque wrench use it and torque the bolts to spec.

Also, make sure you install and tighten the bolts in the correct pattern or else the valve cover is liable to warp.

we ended up putting RTV in between the baffling and baffling gasket, and baffling gasket and top of the VC. It worked really well and cleaned up nicely.

took the old cracked vc off and put the new one on w/ new gasket & rtv in appropriate spots and bolted it down nice and easy.

everything was a breeze and it fixed his cars weird looping idle and the car holds boost a lot better!

only thing is it is showing a misfire that his car was having so new ngk wires are going in asap

Yes just be aware of the difference between in/lbs and ft/lbs as most give you the in/lbs torque specs for the vc.

Haha, yeah! :thumbup:

12in/lb is 1ft/lb. (60in/lb is 5ft/lb)

I have never needed to torque valve cover bolts more then hand tight, so that should let you know it won't take alot of pressure to tighten it down nor will it take alot of pressure to crack em ether so be careful.

I agree!!!

+1 to this. I use one of these to tighten the valve cover bolts:

These valve covers are super easy to crack. Once they do, the will never stop leaking oil and cracking farther.

Also, i recommend to use a Moroso studs kit or equivalent.
