Valve cover: Aluminum vs plastic
I have an 85CJ7/258 with the plastic valve cover. When I bought the Jeep last year the old cover was cracked, leaking like crazy, etc. I couldn't afford an aluminum one at that time and sprung for the plastic kit from 4WD. It has worked great since, but has recently started leaking and I started thinking that its time for the Clifford aluminum cover.
I remembered seeing one sitting on a shelf at Jack's Jeep here in MD. So I called and talked to them and they recommended *not* to go with the aluminum cover! He claimed that they still leak and that the baffling on the inside is flawed and allows oil to blow into the air cleaner.
I've heard nothing but positive testimony about the Cliffird valve covers up to now. I also thought that oil in the air cleaner was more a vent problem or a ring problem rather than a "baffle" issue.
Has anybody out there with the later model CJs switched to aluminum? I'd like to hear some opinions: How long its gone without leaking, oil in the air cleaner, any problems, etc.
