I looking for some opinions on how to stop a leak in my rear end cover. I have tried to reseal this thing twice and it seems to be the same story each time. It works at first but three months later it develops a leak at the bottom. I've heard so many different opinions on the proper way to seal it. I just purchased a new cover and cork gasket. I would appreciate any insight into what to use to along the line of RTV with a cork gasket. In additions the torque specs for the bolts. I have a GM truck 12 bolt.
