Also helps to torque the cover down a little at a time in a spiral pattern beginning near the center & working your way out. Go around a few times, then a few times more. just don't exceed the recommended torque.
Need to clean up my valve cover leaing issue on the 90 YJ. Do I really need to use the goop gasket stuff along with a gasket OR is it better to only use a quality valve cover gasket?
I hate using "goop" on a gasket. If you use a good quality gasket and it leaks then you have an issue. Either you did it wrong or there is a reason for your leak. I mean if you are going to use a sealent then why use a gasket? It also never fails that you will have to scrap the crap off later.
If you have to use a sealent then I recomend Right Stuff made be permatex.
Oil and fuel resistant and it kicks ass used as a gasket maker. Have not had an issue yet.
Follow the advice these guys give, they are usually really good. Also, while you're at it clean all that gunk out of under the valve cover. I'm willing to bet you'll experience a hell of a difference in the way it runs.
with that rtv silicone goop, most people dont use it correctly (im not saying anyone here doesnt know how). but u need to let it cure for a hour or two before u tighten it down on the material. I have had good luck with it but never on valve covers. I would definitely just use a quality gasket.
It works 60 percent of the time....every time.
