Well, this one's twenty. I did give the wiring the "once over" yesterday, but
I'll go over it more closely as soon as it's warm enough and I'm home in
daylight.

Yes, I've had that same failure. I think the 16V has the same oil cooler
thing, but as I recall (and you mention) when that O ring went, I got a
considerable mess under the car. I'm just not seeing any oil under the car at
all. And even if that were the issue, it's full now and has been for a week
and I'm still getting buzzes.

And for one other detail, it does only happen when the engine gets to normal
temperature. It was very cold here this morning and on my drive to work the
temperature never got UP to normal, and no buzzes or lights. On the trip home
this evening, it was 20F warmer out and it DID get up to full temp and I DID
get buzzes and warnings.

Why not take it in and have the oil pressure checked? If it's O.K. at
least you can start fault diagnosing without worrying about seizing
the motor. Replacing both switches is relatively cheap and easy to do
after that it could be the voltage regulator in the gauge cluster or
even the printed circuit.

Mostly that it's awfully inconvenient right now to get my car to the shop and
pick it up again. But yes, I agree. It's probably the best place to start. I
was considering just putting in an oil pressure gauge. So, next question,
what's normal pressure? I expect if I ever find the Bently manual in the mess
that is my office, it'll tell me.

I have to take the cluster out anyway to fix the odometer, so I may as well
check the regulator while I've got it out. Another reason to get around to
doing it, I guess.

This means that the oil pressure is below 1.8bar (25.2psi) when the engines
runs above 2100 rpm. Could be a simple defective switch or in worse case
bearing trouble. The pressure switches are located on the top of the filter
housing.

Thanks. I went looking for them this afternoon, and examined the upper part of
the filter mount based on someone elses suggetion. I found two very similar
(covered with road grime, anyway) looking sensors there. I was a bit surprised
they're that close together. Look fairly simple to replace, so I'll do that.
I'm also going to have the shop run a pressure test on it.

Those two switches may not be switches. One may be oil pressure and the
other may be oil temp. If you remove one and see pressure range you got
the correct one. If you see one that has temp in C then you got the oil
temp switch.

This is true for the 8v engine which has one switch on the side of the cyl.
head and one on top of the filter housing.

Thanks. I'm going to buy the replacement part first so I'll be sure what I'm
looking at when I get it off the car.

Still haven't found the Bentley manual I've got around here somewhere. That
would make this a bit easier.
