Re: TH400 pan still leaking!
The only advice I can offer is, follow the directions, and I mean that in the nicest way. I always read about people with leaks and others swearing by certain gaskets. Rubber, cork, paper, or just sealant I don't have any leaks, and i don't say that with a chip on my shoulder. I always prep the same: clean the surface with a plastic scraper and a soft brass wire brush, wipe with mineral spirits, wipe with acetone, apply gasket per manufacturer recommendations and finger tighten all bolts followed by recommended torque specs. Re-check torque specs in the tightening sequence after running up to operating temp. Fwiw- I do use stock pans, but have the same results with stock or aluminum valve covers.
