Re: Low TJ oil pressure = new oil pump?

Please re-read my post... the oil pressure varies even when I replace
the electrical measurement of oil pressure with a mechanical oil
pressure gauge.

The mechanical oil pressure gauge is attached to a tube which screws
into the block... oil actually goes from the engine up the tube and
applies direct pressre to a diaphragm/spring coil loaded needle... this
is the most accurate albeit old-fashion way of measurine engine oil
pressure.

That's why I asked if it could be more than an oil pump problem.

Re: Low TJ oil pressure = new oil pump?
 

If these oil pressure readings are real, then your symptoms point to worn
out bearings. The pump itself is not likely to wear out, because it is the
best lubricated part in the engine. Other possibilities are a blockage on
the pump intake, perhaps from sludge, or idle speed too low. Clean the idle
air control valve to address that problem. It is odd to see a vehicle of
this mileage with this low oil pressure, even at idle, especially if it has
been maintained well.

We had a woman in the commune who drove probably sixty miles, to find
someone who could tell her what the little blue dash light on her Karmann
Ghia was all about. :o(
