I present this, not as an argument but just general information:
After I rebuilt my current 2000 cc Type IV Air Cooled engine I
experienced very high oil pressure (over 80 psi at 40 mph, the gauge
stayed pegged out).
I considered it might be the upgraded Porsche gears I installed in the
oil pump housing. Not So.
I continued to drive the vehicle through the break in period of 2000
miles at under 2000 rpm.
I took a 278 mile round trip on the highway and experienced the same
pressures.
Ultimately after inquiring of Jake Rabe and some others I discovered a
bur on my oil bypass plunger that was locking it and not allowing the
spring to operate to bypass oil back to the sump.
After I filed the bur off, the whole scenario changed; 22 psi at 800
idle, 45 psi at 2400 rpm, 50-60 at 3300 rpm.
If I hadn't had a gauge to alert me to this problem I would have blown an
oil cooler, washed out the bearings, exploded an oil filter or other
catastrophic event. I thought it was rather strange that every new stock
oil sender unit leaked around the crimp at the meeting of the steel /
plastic parts.
I'd highly recommend installing an oil pressure gauge with any engine
rebuild even if you just use it for 30 days and then remove it.
