80# high output oil pump replacement by alanwoodieman was successful (I'm the owner). Added 1/2 quart of Lucas per recommendation, and the oil pressure is now good on this million mile engine. I have no history on the engine. A side benefit of replacing the oil pump is that a new rear seal has reduced the oil leakage when parked in the garage by 90%. Down to "normal" leakage now.
