Over the pasted 20 odd years I have rebuilt many 5 cylinder engines and this is the first time I have fitted a new oil pump (BGA), in the past the pump was stripped and the oil pump back plate was lapped in to remove any marks, on first start up I did pack the pump with vaseline and oil pressure was not a problem, idle at 2.5 bar (hot) and 1700rpm over 5 bar, any way will fit the original pump and see what happens, I will be having a look at the big end bearings and main bearings before I stick the sump back on.
