I use Permatex Ultra Black (aerosol can). Those damn cork gaskets on the pan are a pain. I use Brakecleen to spray away any bit of oil (after scraping the old gasket off) then install the timing cover using the Permatex. I do not use the cork gaskets ever. After its installed I fill the void with the permatex. Let it dry overnight and your good to go. I've never had one leak.
