I have always been beyond 2.5 but recently hot idle is sometimes around 2 bar.
I also hear a strange noise like a whistle when starting the engine, after 2 minutes the noise is gone.
I think it might be the oil pump if located on the left side. This left side has some oil over the Maserati signing as well...
Must have w60 for Turbos, otherwise oil will get like water..!!
All,
Some update on this.
No more issues with oil pressure, + 3 bar at idle and 5 bar at speed.
Manual check on oil pressure and measurement of endfloat ---> OK. What a relief !
Power fully available after cleaning all pedal pot connector and ecu connector.
Seems like hot summer, south of France might affects oil pressure more than expected. Might use a viscosity improver for summer oil change.
This engine has always been running on 10W60.
VI is an oil additive that improve viscosity when oil is set to get thinner.
The oil pressure improving especially at hot idle.
Bardahl is providing good ones.
Check the pipes that go to the throttle body, my jubilee clips were loose and the pipe blew off the Throttle Body, same symptoms as your car.
Thanks Phil, this helped me a lot. My crank sensor had been replaced and upon driving the car I experienced a huge loss of power. Last night I read your post, this morning I checked and found that one of my jubilee clips had snapped (broken). Therefore an easy fix!
