I replaced valve cover gaskets on two 413s in the past month.
One was a breeze, one was a chore.
The chore: a previous owner glued the gaskets to the valve cover.
It had to be scraped out in little bits. Putty knife and solvent
something like 45 minutes per cover. Cork pieces everywhere,
and then to remove the old adhesive.
I don't use adhesive or gasket maker.

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?
