I just purchased '06 Pitbull and had oil leak at the primary insp plate. My friend has a K-9 and is an experimental aircraft builder, we eliminated the gasket completely. Clean both parts good. Then we used auto paste wax on the primary (rub it everywhere the rtv will touch the primary side including the bolt holes and wait about 30 min), Apply hi-temp rtv "thick" to the cover in place of the gasket (not in the slot - on the outside edge only about 1/4") and bolt it up, do not tighten yet. Leave about 1 turn on the threads. Do not tighten for at least a couple hours. When you tighten it, it will be a permenant seal that you should be able to remove and reuse many times without doing it again. I've put on over 300 miles and no leak! Good luck!
