Default 2.4 L Valve Cover Gasket

I will be looking to replace my valve cover gasket soon on a 2.4 L.

Planning on using a Felpro gasket. Is Felpro ok to use or should I try and find something else?

What about RTV? Is it needed? I have found some info that some people say it is necessary, others that say it is not needed. If needed do you put it on half moons and flat gasket?

If RTV is needed what type?

The job seems straightforward. Is there anything that needs special care? Anything someone should know that hasnít done it before?

Do not use RTV, and the Fel-Pro gasket is working fine for me. I just changed mine as well, and this YouTube shows you exactly what to do. Very straight forward. https://m.youtube.com/watch?v=3W5mqoUmLfY



Just clean the mating surfaces so the gasket seals nicely, and DONT over tighten the bolts. I stripped two, and they don’t need to be super tight. There’s also a certain tightening order you should use….picture below.

Fel-Pro gaskets have always worked well for me, on a variety of engines. Their engine rebuild kits often include several to many extra gaskets -- due to variations in engines -- that can cause, at first, a bit of panic that something was missed! :-)

Thanks for the info. When I saw your pics you attached it prompted me to go look at the FSM that I have. Not sure why I didn't look at the FSM in the 1st place. In the FSM it shows applying a liquid sealant to the bottom of the half moon gaskets. Just want to confirm that you didn't apply any there? How long have you been running with your new gasket?

I attached a pic of what I am talking about.



The FSM doesn't state what kind of liquid gasket to use.

I double checked, and I just realized the FSM does call for a tiny 3mm bead of liquid gasket underneath those moon seals lol. I didn’t put it on mine, and they aren’t leaking, but I guess it technically calls for it.

It didn’t seem to address whether the full gasket was liquid or rubber, which was weird, but everyone uses the rubber and that definitely doesn’t need RTV.

Page 71 has the pics I included if you want to read through more thoroughly and try to find it. https://www.nicoclub.com/service-man...dy/1994/EM.pdf

Felpro worked great for my last two trucks. I did RTV for the half moons but just on the bottom/round side.

I’ve always added RTV to the half moons.

What kind of RTV should be used? There are a lot of different options.

I think 5 of my bolts are stripped out and I used cheap approximations that I got from Lowe's to solve the problem....and promptly forgot about it. Definitely did not use RTV on the half moons. The stock bolts that go in there have that smooth larger diameter extension below the bolt head. It was recommended that I tap heli-coils in there and I'm wondering if anyone has any idea about the specs on the heli-coils and the type of bolt that I should use to achieve a best solution. Forgot to mention that I can't remember what I did with the original 5 bolts with the larger diameter extension below the bolt head.
