Just installed my professionally rebuilt 4 Cyl engine in the BN-2. Cranked
it up and it ran fine but the oil pressure was nil. Gauge checked out good
with air pressure. Pulled the oil pump and found no apparent problem there.
Found minimal air flow thru the oilway between the oil filter and the port
where the oil pressure line to the gauge is attached and found further that
when cranking, oil would only ooze slowly from the block at the pressure
line port. Any ideas for further diagnostics? I really do not want to pull
that engine back out.
