Gasket/seal in cover at hold down post wingnut. There's a tiny 1/16" factory hole in bottom of said recessed well. Mine has a solid rubber seal that covers this hole....steering works ok, but wonder why this factory hole is even there! Or should the gasket be a flexible type to allow the system to "breath" like a typical brake cover has? I don't think I have the "correct" gasket/seal....Help, thanks.
