Finally fixing it

May 29, 2004 40 Replies

I'm finally going to attempt to fix my leaky valve cover on my 85 CJ7



258. From what I've gathered here I should get a new cork gasket and sandwich it between layers of RTV. Couple of questions: What should I use to clean the surfaces that will get the RTV? Is there any brand or type of RTV that is best for this or is it all the same?

...I hear an aluminum valve cover will help it run quieter and leak free..

You might get a bit of space if you jack up on the t-case tail.

Otherwise a small 1/4" drive socket with a universal joint will get it.

I have long fingers and can get a box end wrench on that bolt. It's a bugger for sure.

Do you have a lowered t-case or something like that? That will for sure mess up the space.

If you are really desperate, you could remove one front engine mount with a jack under the oil pan and drop the front of the engine down some. That might open up the space for you.

Are you still running with the computer in the loop?

99% of the vacuum lines can be tossed when the computer is gone.

It still can pass emissions with low numbers if tuned correctly. You either learn how or find an old time mechanic that remembers how to set up a carb. It's not hard to learn.

Oh, I like acetone for the final clean before the RTV. You also have to have the 'ultra' if permatex RTV. This is called 'sensor safe' RTV Silicone.

Regular silicone will instantly kill your O2 sensor, no matter where you use it on the vehicle. If the computer is gone with the nutter bypass, then no worries and you can use the cheap silicone.

You do know that an aluminum cover looks better and runs cleaner, right? ;-)

Jim85CJ did pass the time by typing:

5hp, 10 if you get one with fins.

I've heard you can also get a 5% torque increase by getting one that is powder coated.
