Michael--

Oil pressure did not appear until I removed the oil filter.  My belief is
not that the first filter was defective but rather that the oil pump was
not able to overcome the pressure created by the filter.

In any case I have retained the first filter and will explore its innards
to see if I can find anything further.

Hi Michael,

It isn't bad filter design, it is a product of good design!

When the pump is a bit tired and has air in it, it can't make enough
pressure to overcome the filter's anti-drainback valve flap so will
not pump oil until you unwind it a fraction to release the air. Once
primed it will stay primed until next filter change.

There are a lot of filters out there with non-functioning drainback
valves, including some KnN designs. Looks like you found a good one.

Andy.
