258 valve cover

Hey all, what are your opinions about valve covers? I currently have a clifford but am unhappy with it. It is leaking out of the rear portion of the cover. I have replace the gasket twice and it is ok for a while then starts agian. Also it takes forever to fill the engine with oil because the fill hole has a baffle which obstructs the flow into the engine. Also what gaskets have you all had luck with. Thanks for the help.

Re: 258 valve cover

I've never seen a reason to switch from the stock cover. As long as the screws are tight it doesn't leak.

Next time yours startts to leak, take it off, remove the baffle and reinstall the cover. Then every morning, before you start the engine, tighten the hold down nuts. Dont overtighten them; just loosen the nut and then retighten it to the proper torque. At first you'll get a little extra out of them on the retighten, but eventually you'll find that they're turning right back to where they were. After that, just check them when you change oil, and you probably won't have any more leaks.

Don't use a gasket. A nice bead of silicone works great.

Re: 258 valve cover

I got a new valve cover from a swap meet, haven't had a problem since I installed it. I used the cork gasket it came with and a little silicone. Othen than being an idiot and drilling one of the holes too deep it's been fine. Hole in my head [img]images/graemlins/cussing.gif[/img]

Re: 258 valve cover

I found a very nice cast aluminum cover from Westside Performance that works extremely well. Looks like the stock plastic in terms of shape but is a very solid cast. Cost a bit more than most aftermarket at about $160 but I have never heard anyone complain about their performace.

This is the link to their website.

Re: 258 valve cover

Does the Westside Performance valve cover require the head to be drilled and tapped like most aftermarket covers do?

Re: 258 valve cover

No it does not require drilling or tapping. That is one of the main reasons I bought it. It uses the two stud (rocker bridge) mounting posts on top of the valve cover just like the one used by my 84 stock plastic cover. The big difference is that you can torque down the aluminum cast head hard enough to prevent leaks. Everytime I tried that on my plastic cover I would end up cracking the case. The Westside cover comes with a special integrated nut/washer/grommet combination that prevents leaks out of the top as well. Even if your head does not have the rocker bridge studs this is an easy add on kit that either comes with the Westside or is available seperately I forget which.
