High oil pressure 2003T

[whiteoaks7]

I seem to have high oil pressure on the Volvo 2003T after the winter layup. Any ideas? Filter and oil are both about 30 hrs old. No leaks that I can see. Is there a relief valve that might have stuck? Pressure is about 80psig.

There is a relief valve SEE

From the workshop manual:

Oil pressure, warm engine, idling speed . . .0,8-1,5 kp/cm2 (11 .37-21 .33 lbft/in2)
Oil pressure, warm engine, full rpm . . . . . .3,5-4,0 kp/cm2 (49.78-56.89 lbft/in2 )

Interesting level of precision for the psi figures /forums/images/graemlins/shocked.gif

More likely to be a defective gauge or sender ????
