Hey everyone. My 350z has a leaky rear main seal...why? No clue. It probably folded over the spring seal and didn't seal properly. While I was changing it, I did the upper pan gasket. Huge PITA but i've removed the upper pan 3 times now and am hoping I don't have to do it a fourth time. Since I just changed the seals on my upper pan, will I have to do it again while changing the rear main seal again? Or can I just skip that step this time around?
