The oil pressure relief valve is intergraded in the oil pump according to the manual.

The minimum allowable oil pressure is 0.3 bar (4.4 psi) at idle and should be at least 3 bar (43.5 psi) at 3000 rpm (1000-1500 rpm is the norm).

I think your sensor is out of spec. If your mechanic measured 8 psi when testing the oil pressure, the gauge on the dash should have registered 0.5 bar.

What weight oil are you using?
