I'm following up on all the advice I received for my
'87 Westy's low oil pressure problem. The warning light
and buzzer come on after about 10 minutes of driving
on the transition from high rpm to low rpm. Typically
this is when the rpm's fall below 2500.

The oil pressure sensor that the dealer replaced is
a 1.6 bar sensor located in/near the oil filter flange.
According to the dealer fiche there are two other sensors
a .9 bar sensor near the oil pump and a .3 bar sensor
somewhere else. (??) In the Bentley's I only saw two
sensors. Does anyone know which sensors perform what
function and which one I should be looking at for the
high to low rpm transition warning? Dennis, I think
you indicated that the one near the oil pump might
be the one. I just had the dealer order one. Any help
with resolving this is greatly appreciated!

ps - for those who just tuned in, no need to discuss
oil type, filter, pressure relief piston or oil pump.
