opinions on valve cover
Hey guys... need some opinions...
My valve cover gasket is leaking so of course I'm going to replace it... with a fel pro vs50522t gasket... I believe that's the part number, now the question is since I'm going to take off the valve cover should I replace it with a younger year?
I'm pretty sure mine us the stock aluminum one... I think the younger years were of steel, and had the pvcs on them...

Yeah, my dad always said "if it ain't broke, don't fix it." In this case, he is right. If it isn't damaged, don't replace it. Just clean it up real good, maybe shoot some new paint on it and make sure that your CCV breather ports are clean. If you need to, now is the time to replace all the CCV stuff while it is off. I need to replace my VC gasket and am just waiting until I get all new CCV stuff before I do. I'm also going to do the VC mod to help the system breath better.

You'll be in danger of sucking oil into the intake manifold if you mod the vent or CCV system on the valve cover.

Not that I know of... I just figured when my valve cover gasket comes in on friday I can clean it up and do w.e else needs to be done since I'm taking it off...
I know I need to clean or replace the ccv, I have a little oil leak around the valve cover, and the grommets on top, as well as when the hoses intersect at a junction but my air filter so far is oil free

The renix mod involves cutting about an inch off both flutes (i think thats what they are called) then drilling a hole in the side of the remaining flute. I believe it is detailed in cruisers renix tips.

The aluminum valve cover you've got IS the earlier one. Use it with the Felpro gasket. Make sure your CCV lines and grommets are in good shape. The mod is below:
Cruiser’s Valve Cover Mod
Most early and even later Renix 4.0s could be bothered by excessive oil in the air cleaner box. A fix from my old days as Service Manager at a Jeep dealership follows. Information was provided to me from a buddy at JeepTech during those days. I don’t believe it ever came out in a Technical Service Bulletin.
Remove the valve cover and turn it over. Next, remove the fluted tubes that are now facing you by removing three screws on each. Chop 1 inch off each of them. Then, about a half inch up from the area where you just sawed them off, drill a half inch hole in the tubes so the holes will face the rear of the valve cover. Clean and de-burr/sand all rough edges nicely, clean with solvent, and reinstall. Don’t be concerned about the chintzy gaskets that will probably crumble into oblivion when you remove the fluted tubes. They can go back together without gaskets.
