Hi Jack:
When working a significant problem like this, look for the simple problems
before taking drastic action, like pulling an engine. So assume the easy and
obvious.
Take a look at the oil in the upper cylinder head area. If oil is in that
area, then some oil pressure exists. The oil has to get there someway,
somehow. If no oil is reaching the upper cylinder head then this is a good
sign you have a problem. Conversely with plenty of oil reaching the top of
the engine then you have a problem with the gauge and the oil passage to the
gauge.
Know that I seldom check this email address, other than weekends.
The advice to check with you rebuilder is excellent. He is on the hook for
this and should advise.

Subject: Zero Oil Pressure - None
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.
Jack
