I've got the motor torn back apart again. There are no contact marks on the oil pan. There are very slight signs of contact from the nuts on the main cap touching the windage tray. The replacement oil pan gaskets that I installed are slightly thicker, so there isn't anymore interference. The problem that I'm having now is trying to get the upper half of the rear main seal out from the block. I think it's from the rtv on the back of it holding it in. Are there any tips on getting this out without it breaking or ruining anything with the block or crank. I'm afraid of it tearing and still being stuck in there and then I'll be screwed.
