Cast Valve Covers

[Weasel]

Anyone had any experience with the fancy cast aluminum valve covers like quadratec sells?

ie like these, maybe they are mopar not sure:

I bent the lip on my stamped steel cover last night breaking the silicon seal and since the steel are similar in price figured I'd consider them. 97 4.0 is the engine year.

I have one on my 90 RENIX. The cover itself is for a 96 model XJ though. It works great, no issues.

I have been eyeing those for a while too actually.

Looks like the breather tubes clip in the same? What kind of oil cap does it have, does the ratcheting one work?

Those are made by Crown. Everyone I know that has them likes them. Only complaint I've heard is some people don't like the plastic push in oil cap. They work fine, but some people like to go fancier and get the Mr. Gasket ones from local auto stores.

Do the rubber washer in the stamped cover need to be replaced with the cast cover?

Push in oil cap? Hmm, I like the one on the stamped cover.

I hated the ratcheting one, I replaced mine with a 1 piece cap.

The cap is kinda cheesy but it works. I would pick up some new grommets for the install. Its just easier to cut the ones on your old cover and pull the elbows out so you dont snap them.

any vendors carry these?

Trailrider your talking about the breather elbows, correct? I meant the ones in the bolt holes of the steel cover.

My bad, yes I was talking about the breathers. The bolt holes do not take the grommets but you do use the metal/rubber valve cover gasket.

Quadratec is a vendor...

Maybe these could make a good group buy item if someone else sells them ; ) .

They're $96 shipped from Morris4x4 with discount, and they're also a sponsor.

Does the Mr. Gasket one have a threaded oil fill hole? I've considered getting one of these covers, and knew the oil cap was included, but didn't realize it was a push in. For some reason the idea of relying on a big cork to keep oil from spraying all over my engine bay makes me a little nervous...

I've only heard of one person having reported the cap coming out, and he also mentioned he had serious blow by and other issues going on so I equated it to that.

I don't know the details on the Mr. Gasket oil cap, only that I've seen it mentioned a few times. There was a write-up on here a while back that mentioned it as the guy installed the same red cover.

The covers are also sold in black, and yellow. Comes with the nice rubber covered metal gasket.

Even though the cover is for a HO head it still is a direct swap onto the renix heads?

ok since we are on the topic about the oil cap... where can you get the breather pieces that go in the valve cover for the renix? mine leak. i have tried the help section in the parts stores but no luck. is this a dealer only thing?

Yes, the valve cover mating surface is the same on all 4.0. The only difference is the CCV system which sucks on the RENIX anyway so i swapped mine over to the HO CCV system and did away with about a mile of plumbing.

The dealer should have all of those parts
