Okay, I have done all the research, but still have a quick question. When reinstalling the timing cover, is it totally neccessary to cut the rubber oil pan gasket? That makes me a little nervous. I have not had good luck with any type of cork gasket. I would think that I can just put some rtv in the corners where the rubber pan gasket meets the block and timing cover. I would like to reuse the existing oil pan gasket. Is this possible?
