Problem---after hanging the engine/trans at the angle in the pictures, oil is dripping out of the crankshaft seal. I was hoping it was the oil pan leaking, but it's the rear main seal.
The seal is a BOP lip seal installed by the engine shop that did the machine work and assembled the crank/rods/pistons. We'll call him tomorrow, but I'm afraid of what comes next. We have the heads/cam/timing chain/cam degreed, rockers installed & adjusted, engine primed with oil--almost ready to run.
The only good news is this is better now than after we start it up in the chassis. I'll keep you posted.
