Tradutuinally in VW oppossed 4 engines..
going back to the air-cooled days the oil pump Cover gasket is really
really thin.
( I like to give them a very light SPRAY coat of Permatex High Tack
gasket sealer ..the red stuff ...which I could not fix cars without. )

there's also the old, old trick of turning the Oil pump Cover 90 degrees
to get a new wear area on the cover going.

I drove one very high miles 1.9 wbxr engine  that had the oil light,
when warmed up, on any time rpm was below 1.500.
Ran great though ..
did 300  + miles freeway miles with it no problem.

Have seen engines that idle at  0 psi when hot.  That  was The Only
symptom, otherwise just fine.

I can't recall offhand what I measured it as, buts something around 10 thou. I think the pump two case gasket is a outs 12 thou.

I later ditched the gasket and used loctite 518 ( or is it 508?), and that gained me a few more pounds pressure. As I said, the engine is old and I am not in it for the long run so the oil pressures fine for me at the moment.

Driving the interstate at 65 mph, oil is at 22 psi, drove for another 40 miles down to the exit ramp and oil pressure light/buzzer goes off at the end of the ramp. PSI was at 6 at 900 rpm's. Is this common? Or is there a problem with my new GOWESTY engine that has 3000+ miles on it ?
