BTDT! Oil light and buzzer came on regularly. Got the proper switch from
Van Cafe and installed it - no more problem. Aggravating to change out,
though. Had to remove the water pump pulley to get at it, and that required
loosening the alternator so I could remove the water pump belt. Then I had
to have a special socket (I made mine) to remove/replace it. A very tight
fit! But it solved the problem!

The Waterboxer does not like 10w-30. Who rebuilt the engine? Was the case
actually measured for wear at the bearing journals and align bored? This is
the usual problem with rebuilt engines not maintaining sufficient oil
pressure. Oil pressure testing with the van sitting will not reveal the
problem. You have to leave the gauge on and drive on the highway for a
while. As for the switches many of the aftermarket ones are not reliable.
Go to the dealer and pay the $$$. Also make sure the oil level is correct
and not over filled. Over filling will cause the oil to overheat and lose
viscosity. Adding a real oil cooling system can also be helpful.

Hi all,
My '87 Westy auto is having the problem wherein the oil buzzer and light
come on after about 15 minutes of driving when the RPMs drop below around
2500 RPMs. I've had the oil pressure checked and it is fine. A friend of
mine is having the identical problem. Is the high pressure oil pressure
switch, part number 068919081A, the culprit here? I checked the archives
and it appeared that there may have been a problem with some of them being
too sensitive or something...? I'm trying to find the right part get this
sorted out. My friend is about ready to take a hammer to his buzzer . . .
Mine is going to be fixed by the guy who rebuilt the engine. He says he got
a bad batch of switches. I'm just trying to find which is the right part
for my friend to order . . .
My van has a newly rebuilt engine and is running Pennzoil 10w-30. I've
never run less than 20w-50 in it and never had this problem, but the guy
who built the engine swears that the pressure is fine and this weight of
oil should be fine, that it's a faulty oil pressure switch.
My friend is running 15w-50, I think, and has a fairly fresh engine as
well. I suspect, but do not know for sure, that his oil pressure is fine.
Bus Depot has this one:

Is this the right switch to fix this problem?
Thanks,
