Valve Cover Gasket Replacement

Hi,

I have a Camaro 91 V6 w/ manual transmission and yesterday I noticed that while driving there was smoke coming from the right side of the engine (near EGR valve). I believe the valve gasket is leaking.

Do I need to remove the upper plenum, fuel rail, lower plenum and then remove the valve cover ?
If/any other things I need to remove or think about ?

Does anyone have pic of all the steps on how to replace the gasket ?

Many thanks !

No one has ever changed valve gasket on a thirden camaro

No need for pic if no one has it, just explanation in text would be fine.

Re: Valve Cover Gasket Replacement

To do a valve cover gasket, yes you have to pull the plenum and fuel rail. You will also have to remove the EGR/tube and coil/bracket. Get a Haynes manual if you are going to do this, not only will it have the steps, but the torque specs and sequence for the intake. For $20, it will come in very handy. Also, get new injector o-rings, its cheap insurance so you don't have to take it back apart when you end up with a fuel leak.

Re: Valve Cover Gasket Replacement

if you can see the leak, and clean the area well, a bit of RTV on a finger can often stop that when its a non pressure leak. v cover, oil pan... non pressure, can't fix oil coming out a head like that.......

spray ladies dedorant with baby power is a good leak tracer.

Re: Valve Cover Gasket Replacement

You don't have to remove the intake manifold, but it does make it a whole lot faster. I'm lazy and am swapping to Fiero valve covers. I left the intake and what not on, and finished the driver's side swap. Working on passenger side today. Really, it's a pain in the ***, so it probably would have been better to pull everything and do it the right way.
And 2nd Haynes or factory service manual.

Re: Valve Cover Gasket Replacement

For a couple of years ago a mechanic i knew replaced the gasket between the upper and lower plenum and since I will be removing the plenum and other stuff myself I am wondering if I need to replace the gasket AGAIN between the plenum or can I re-use the older ones ?

You can't reuse those gaskets. The intake gasket set is cheap enough, don't risk a vacuum leak.

Re: Valve Cover Gasket Replacement

could take a cereal box n ballpene hammer n make a gasket if you want to be really cheap.

rec did that for the water neck on my V8 car, worked like a charm.
