When my car (03 MY C2 tip ) is warm ,there oil pressure is now showing 4 bar at 2000rpm rising to 5bar above that speed ? At idle it drops to 3 bar. Been off to Parr who checked it on the computer and no problems showing. If I switch the engine off and back on again it settles back to normal but then after a short while goes back to doing the same.Engine oil is Mobil 1 0-40 and it seems to use very little of it . The engine has only done 30K and properly serviced . I have not had to top it up at all for some months . Only other things that may be related are that I have the lumpy idle problem quite often and there has been a strange rumble and vibration (like a knackered wheel bearing ) from the rear of the car but this too has been checked and all drive links ,suspension and bearings seem to be tip top !? The assistance of all you wise ones would be much appreciated .
