{Chrysler 300} Re: Gasket maker. Yes or no?

[Dyke Ridgley <ridgleyracing65@xxxxxxxxx>]

I am sure you will get lots of suggestions. On standard American engines with cork gaskets, we use black weatherstrip adhesive to permanently bond the gasket to the valve cover and then put a light coat of grease on the gasket surface that contacts the cylinder head. The gasket does not squeeze out, no leaks and easily removable many times without any gasket damage.

There has been a debate for a long time regarding the use of gasket maker on valve cover gaskets. I’m about to take on the task of changing my valve cover gaskets on my 300F. They are cork gaskets and typically I would not use gasket maker. However, this is a big job and I only want to do it once. I’m thinking of using spray on copper gasket maker on the valve cover side only. What are the thoughts out there?
