[Vwdiesel] Is it weird oil pressure?

[Shawn Wright]

Yes, you are correct, 1.4bar at flange, 0.25 bar at head in the case of my 
'86 TD. In my TD before I tore it apart, I would have the buzzer go off after 
a long climb if I let revs drop near 2000. At this point the mechanical gauge 
was showing about 17-18 psi at the head. Buzzer goes off at 1.4bar (20.6 
psi), so this suggests that head pressure is not that much lower than at 
flange, assuming switch and gauge are accurate. I always planned to 
move the gauge to the flange, just to see the difference, but never got 
around to it.
