On friday I removed the fuel pump and replaced it with a proper blanking plate. Had to trim down the bolts - they were too long to fit all the way in without the thickness of the pump and its spacer. It looked like the original owner had cracked the plastic spacer between the pump and the block and glued it back together, and that may have been the source of the leak. The gaskets were totally oil-soaked, so there was definitely leakage from that area. the good news is that after a 30 mile drive or so I don't see any fresh oil on the back of the engine. The bad news is that even with this area plugged (I assume) I'm still dripping from someplace (else). Gah! :frown2: I'll swap the rocker cover gasket next, but I'm pretty sure it's not that... The quest continues....
