Why is my rear main leaking!?
Well for some of you who have been following my H/C 6.0 buildup I have come so close to finishing it off but these oil leaks are killing me and putting a halt on everything.
The first time I started the car it ran great but was leaking a good amount of oil from the bellhousing/rear of motor area. I checked the oil pressure sending unit and other common places before breaking down and pulling the trans to find the leak was indeed the rear main seal. I then replaced the seal and the rear cover gasket and felt 100% sure everything went on correctly. Seeing as I had a new reverse lipped seal I pushed it into the cover below the surface and everything and it seemed to go on the crank very nicely. One thing I noted while doing this was the the gasket came from GM with some lube on it and I installed it that way as well, I also did not see a need to drop the oil pan because it didn't affect the centering of the seal any and we had a tight seal around the whole way.
After putting the car back together I now still have a leak which is probably half as bad but a leak is a leak nonetheless and I need to fix it. My question is why is the rear main leaking again? Are there any other possibilities? I checked the oil plug in the crank while the cover was off and inside the crank was bone dry so I left it as it was. I also have a brand new oil pan gasket installed so I don't see that being the problem. I really just need lots of input on whats happening because I'm at my whits end pulling this trans again and if I do need to replace the seal I want it to be the LAST time. On that note I have also heard of people putting the newer style seals in backwards and having good luck what do you think about this? Please help me.
