My stock sbc valve covers with the spreaders are starting to leak. I am thinking about buying some aluminum covers with the bolts on the top and bottom. Do I need baffles or not. Who makes and sells a good quality aluminum valve cover that will not bend or leak? Are there any brands to avoid?
With your help I will only have to do this once. Too many things are taking me three tries to get it right.
Thanks

I tried some new style fel pro gaskets. They say they seal better and last 5 times longer than the old style. They have a hard plastic frame with a spline type seal. Similar to the vortec intake gaskets. you put them on dry and I think they are reusable. They have plastic spacers so that you cannot over tighten them.
They make two models the 69.00 ones and the 35.00 ones. For what they charge I hope they work well.
Has any else tried these?
Thanks

Take the gaskets out and throw them away.
Stop at any parts store and buy a tube (or two) of Permatex Ultra Copper RTV gasket material, it's also known as Permatex Red.
Clean both surfaces relly well and then wash them with alcohol. Follow the package directions, don't over tighten the hold-down bolts and you'll never have another leak.
I did this to the valve covers on my old truck and never had a leak for the last 95K miles and 10 years of ownership.

Unless you're continuously removing the covers for some reason this is the way to go.

Iggy,
I have tired the blue and the black permatex. I think the heat in arizona just cooks gaskets. The cork is good for a few years and the rubber is good for about 5 years.
I will let you know how long theses new gaskets last. At least it will be easy to change them. No scraping off the old rtv.
Thanks

The Permatex Red is a high temp type RTV. The heat of the Florida summers and exhaust manifolds didn't destroy the sealing abilities. The Blue and Black are not designed for use in high heat locations.
Trust me, this'll work.
