I have completely rebuilt the 85 Mercruiser 140 and she runs like a top! however the new 2 piece rear main oil seal(Fel-Pro brand and it came with the kit) is either leaking or the pan gasket is, it's a 4 piece pan gasket.
This appeared within an hour of the first start up after the rebuild. I installed the seal by the book(shop manual) proper off set, lip facing the correct way and used the recommended sealant in the correct areas.
I decided last week to remove the pan and have a look at the seal and gasket. I couldn't find any areas of the oil seal or pan gasket that appeared to have damage or not properly installed, so I put it all back together and started her back up yesterday only to find that I still have the oil leak.
I did not see any engine oil on the backside of the flywheel, so it appears to be Dripping straight down.
The Mercruiser is still on the ground and I will not install it back in the boat until I can figure out what to do to fix this issue
any input would be appreciated!
