We lucked out on the main seal leak. It wasn't, and one of the guys with way more experience diagnosing these things realized what it was before we started removing the whole drive train. Turns out it was the oil pressure sender!. It sits on the back of the head on the M30, and it's directly over the bellhousing. With the wire connected and the boot over the connection, the oil was seeping out through the connector, through the boot, and running down the joint between the block and bellhousing. That resulted in a drip (or POUR when you really revved it ) and it appeared to be coming from inside the bellhousing from the rear main seal. New oil pressure sender installed, problem fixed.

Eddie, Mike and Cliff watch the car go up on the lift.

Our host, Dr. Gerry Sparks, spots the oil leak and points it out to Bill, Eddie and Mike.

Mike discovers the source...the oil pressure sensor/sender

The 6er shared garage space with the host's BMW Club Racer, a D Mod E36 with a really nasty sounding S52B30. The engine had just returned from a rebuild after it melted a piston at Barber.

Nice, clean, straight racer

And the muscle that powers this beast. Man, it sounded good!
