: Valve Cover Gaskets

09-16-06, 10:01 AM
I took my 2000 to the shop yesterday becuase i noticed a running oil leak, the mechanic said that he thought it was the valve cover gasket. It does look like that was the source of the leak. How difficult or expensive is this goin to be to fix?
Aswell today i noticed a little bit of smoke/steam coming out from the front wheel well. The temperture gauge never goes above half, so i dont know what the problem is. Please Help.

I also need to track down a new coil spring for the right rear?

Its probally the valve covers themselves, warped, stupid cadillac put freakin plastic valve covers on these things...not sure why, i think i got it done for $600ish

Plenty of cars come with plastic covers and I've never seen any warp. My valve cover gaskets are leaking slightly as well, its a common problem.

I recently got a 2000 cater as well, when i was checking under the hood i noticed oil a lil dry (dont think its fresh) on the bottom end of the engine. Could this be a valve cover leak or a leak in the past??

I have the same issue too on my 97 catera,it helps if you torque the valve cover nuts when the car is hot,be careful not to snap the bolts,i have this problem since last two years almost,but never had problem with missing or anything related to ignition.

I did this not to long ago. The gaskets cost me $30 at Advance auto.
and it took me about 2 hours to do it. It is a pain, but I'm not paying
Caddy $600-$800 bucks for something I can do.

NIce pictures -- we are tackling the same project next weekend. How many gaskets did you need for both sides -- does one gasket wrap around the bottom and top or are they two separate gaskets? Where does that large half-circle part go? And lastly, what are you doing in the one picture with the Coke bottle? Looks like you are basting it!

For info, here is a maintenance guide showing how to tackle this...


You MUST clean the breather system as its this being blocked that normaly causes the leak....

Also, when placing the sealent as described, check and double check that you havn't blocked any of the oil exit holes on the front cam bearings or you will get oil leaks through the cam seals....

Have leaks from valve cover gaskets been known to travel all the way back to the rear diff area? Not my idea, someone gave me this explanation.
