pressure test the oil pump OFF the motor.
If it has been over-bored and the machinist has touched the base of the pump the oil will flow past the bottom of the vanes.

The pump was tested on the bench yesterday, it propelled, indeed projected, oil more vigorously than expected! The flattened and polished pump bottom plate made a guest appearance in episode 76 some weeks ago, or was it years ago.
Further advise will be required in due course. As almost everything else has been checked and/or changed, I will get new and thus correctly shaped jets. Hints on how to remove the old ones and install new ones? And lowering the drive gear down onto the oil pump drive shaft. Does this just require long and gentle slowly offering up the gear trying to find the slot for the key, before tapping it down the shaft, or is there some cunning way of aligning it. Advise so far is to find someone else with small and nimble fingers who makes clocks and watches and works as a neurosurgeon during the day.
