The Stovebolt Site Forums The Shop Area Engine Shop Oil seams comming out at the end of the engine

Hello,
it seams that oil is coming out at the end of the engine. I think the Rope Style Rear Main Seal lets oil out. I had a rubber seal assembled. May be that didn't works.
If I like to change the main seal. Want have I to do?
If you will give me an answer, the do it step by step how I have to change the seal.
