The factory gasket is expected to be a lifetime gasket. When you pull the pan and find the ribbed rubber gasket with inlaid metal, that's the factory gasket. Wipe it down and check for any issues. If none, reinstall it dry.
The rubber/cork replacement gaskets should also be installed dry. Most gaskets on our motors are meant to be installed that way with minor exceptions.
Oil pan, dab RTV in the corners where the front and rear covers seal to the block.
Timing cover, light coating front and back of the gasket at the bottom 1.5 inches.
LIM, dab in the corners were head meets block. Dab above and below the gaskets.
When using RTV on a gasket we should remember how much harder it is to clean. I've known mechanics to add charges for labor due to the extra time to clean off RTV.
