Well It Finally Happened

Okay Guys,
Well now I've got a pretty good oil leak that appears to be coming from the main bearing seal. The oil LOOKS like its coming from the transmission bell housing which means we are either removing the drag link and trying to drop the oil pan or the entire engine is coming back out (not my choice). Do you guys think we can get away with changing the seal in the car or is it my worst nightmare come true and I'm pulling the engine?
Here's something posted by a FABO Member a while back It can be done in the car but it sometimes won't be fun..
