I have an 85 truck with a recently rebuilt engine. I am having a bad oil leak coming from the oil pump.It looks like the oil is coming from where the end of the crankshaft meets the oil seal. I have recently replaced the oil seal and the oil pump gasket is in the right position. It's still leaking alot of oil from the oil pump. It did not leak from this area before I rebuilt the motor. Does anyone have any suggestions about this problem? thanks, Mark in CenTX
