Drivers side cover, only leaks oil from the rear, bottom bolt. The leak is slow, but yesterday over a 200-mile trip, enough came out to move from the bolt to the reaer of the cover. I changed the gasket last week to try to fix it. Used new bolts (proper length) and cleaned everything meticulously. I used Right stuff to hold the gasket to the cover and nothing between the gasket and head. I put a small dab of Right stuff in each bolt hole. I'm using cast aluminum covers and not over-torqueing the bolts. Kinda lost on a fix. I have some regular thread sealant I could possibly use. Any ideas?
