Hi all just seeing the post about oil temperature got me thinking about the oil pressure
I have some digital gauges and the pressure jumps all over the place on idle it's about 25
When I boot it goes up to about 150 i think I have 33 pump what sort of pressure should I be getting
I think the sender could be faulty as there is no consistency i am using an elbow adaptor so the oil and pressure sender are together
Thanks chaps

For what it's worth
Mine starts at about 60 psi when cold dropping to 40 fairly quickly as it warms and I am driving.  When I boot it the pressure does increase  a little with the revs.
Before fitting an oil cooler once it was very hot after a high speed run the idle pressure would drop to 30 or so

BUT

Mine is not a digital guage but analogue, these often respond more slowly
I have a non standard pump (cant remember which)
I have no idea how accurate the numbers are, unusual change is what I am looking for

150 is a lot for any engine and would guess the standard vw cooler would not like that pressure, to get those readings as you say the sender is possibly faulty or miss matched with the gauge unless you have a bad connection in the circuit.

That's a faulty gauge... Pressure should read between 40 and 70 depending on oil used, temperature and engine speed.
150 would blow the little rubber seals under the oil cooler.
I'm in my buggy,
It's raining,
I really don't care.

Thanks all I have something to go on now I'm sure it's the sender
I would like to find a dual sender if they do such a thing
To match my gauge and then I could do away with the elbow the one I have come as a matching pair
And was new
