Full flow system... when you rebuilt it, did you put a plug in the oil gallery where oil normally runs from the pump into the case ???

Have heard around that if that gallery is left unblocked, oil can run through it into the sump instead of going around the engine like it's supposed to... basically losing pressure.

One of the engine builder types will hopefully comment.

Far as I know you plug the case as well as the pump.

This is just from what I've read round the place tho - I'm not an engine builder, so am far from an expert !!!
