I did an oil pressure test on my Vanagon today and I think the results are the
ones that I am looking for but not totally sure 'cause I don't have a Bentley
yet.  Here goes:
Startup - 60 psi at 850-900 rpms
30 min later with fan cycling 5 or 6 times
12 psi at 800-900 rpms (850 really)
29 psi at 2000 rpms.
Are these the numbers I should be getting?
I also got two of my pressure senders today from my local foreign FLAPS.  Both
senders were $12.  One of them says nothing on it and the other says "1.6 to
2.0 bar".  I think the one that says nothing is the below 2000 rpms sender and
the other one is the above 2000 rpms sender but I am not sure.  This parts
store has given me the wrong part so many times that I really don't trust them
so could one of you parts gurus please give me the proper numbers?  Thanks in
advance.
Testing the pressure was alot easier than I thought.  I bought a pressure
gauge kit ($12) and removed the tin from under the engine on the driver's
side.  Then removed the sender found there.  Screwed in the line fitting and
started testing.  It was a manual gauge by the way.
I have heard that it is a pain to replace the above 2000 rpms sender and that
alot of dealers were just bending a pin on the sender control unit and
eliminating the > 2000 rpms sender altogether.  You still would get a red
light from the other sender if your oil pressure was truely low (like all the
other VW before '85) but you wouldn't get all the false alarms that you get
with the two sender setup.
Anyone else know if this is a good idea or not?
Thanks
