Long story short, I spent two weeks researching, cleaning off and aligning timing marks (three of them) and removing access panels and accessories. I would fix this sucker. After all, how hard could it be? Then as I was waiting for the courage to remove what I was sure was the offending pump a man rang my doorbell and asked if I had an Oliver for sale. He needed one. I told him the situation as best I could. He made an offer on the stipulation I put it back together in running condition so he could load it, which I accepted and which I did.
I have rebuilt and rebuilt again many td engines. The problem I often have afterwards is a leaking rear main seal. When rebuilding these engines I often note that it has a three notch or three hole head gasket. When I measure the piston to deck height clearence it invariably calls for a single notch or hole. My wife’s 91 Jetta wich we bought new had main seal leaks and the dealer changed the seal and clutch plate under warranty in year 8. Now when I disaaembled the engine I noticed a three hole head gaskett. Maybe the dealer put it in I don’t know. Other 92 engine I disassembled was the same. Is that the solution to the leaking real main seal? An aftermarker dealer in San Deego California told me not to retorque the head bolts for the second time after 1000 kms. Maqybe that is weakening the bolts? Do you have any ideas?
