valve cover gasket - sealant or no sealant

[centralnc]

I have a question for the group. When replacing a valve cover gasket do you also use a sealant or just the gasket? My brother and I are arguing about the best way to put a gasket on the 4.0L!!

 

We are just planning to use a $7 cork gasket and not one of the $50 specialty gaskets. Thoughts or comments?

DO NOT use that cork gasket.

 

give it two weeks...it will leak.

 

 

drop the cash on the rubber gasket, and use RTV ultra black sealant on the valve cover side of it. that way you can remove the valve cover if/when you need to, and reuse the gasket.

no cork for sure, but please don't use silicone, i hate that. its not supposed to be there, it wasn't there from the factory, no service manual says to put silicone on it. and it makes it stupid to replace the gasket down the road with silicone everywhere in the tiny crevices of the valve cover. just my opinion, but i replace gaskets all day long, and i get pissed off when people put silicone where it doesn't belong.

eh. now my $#!&'s waterproof. I even silicon'd around the oil pan gasket and head gasket after everything settled in...offroad guys do it to keep small grains of whatever you're in getting in the motor.

i just want to have a look at my valves and I'm wondering if i could just use gasket maker or should i use a real gasket to put the valve cover back on?

[JeepcoMJ]

SOB!!! :fs1: I just went through all that crap and put on a cork gasket! Crap, looks like more practice for me.

I'm running a 97+ XJ valve cover on mine with the Felpro rubber gasket and no RTV. No leaks.

 

Now, RTV on the front corners of the oil pan and around the RMS area is a good idea even with the nice one piece gasket.

:nuts: cork works great as a sound deadner on walls. but not for olding oil in a motor.
