Post by: Mutz on May 13, 2007, 13:27:06

Haynes not to helpful as it just says between 25.0 - 55.0 at normal operating temp at operating speeds.

From the workshop manual:-

With engine running at idle check oil pressure,
which should read 1.76 bar (25.87 lbf/in2).

Hope this helps a little :wink:

Again from the manual:-

If pressure is low it can be caused by the
following:-
Thin or diluted oil.
Low oil in sump.
Choked oil strainer.
Faulty oil pressure relief valve.
Excessively worn or damaged oil pump
displacement gears.
Excessive crankshaft bearing clearance.

Sorry if this teaching you to suck eggs, good luck  :wink:

but wanted to check pressure myself.
