oil pump prime (saga continues)
'97 D1. Replaced water pump, front cover gasket, timing chain and gears. Had issues reassembling, removed front cover, and had fractured oil pump gears. Replaced w/ gears from AB, reassembled, no oil pressure. Forced oil into every port, pipe, and hole while turning engine forwards and backwards. No oil pressure. Dismantled and packed pump with vaso. Pulled vacuum at block where front cover interfaces and drew oil (no air leaks). Packed port in block with vaso & reassembled. Still no oil pressure. I can push oil through the system with a syringe, so I know the cooler, filter, etc are not blocked. I have verified there is truly no oil pressure, not just a faulty sender. Trying to force oil back through the pump, front cover, and block down into the sump. Have a feeling the vaso has it clogged up. Even heated up oil today on the grill and forced it through the oil cooler pipe fitting on the bttom of the front cover. No dice. I try turning over with plugs out, etc., and I have also fired it and let it run. Not moving any oil. Even applied compressed air to the system to move some oil throughout the system. When I put a gauge on it, I get a few pounds of pressure, but then it stops. Not sure what to do- had it apart and back together three times now. Know what I would like to do. Let me know your thoughts.
