Hi, Today when I took my car for going home there was no Oil pressure when I started. The pressure was just fine in the morning. Fine for me is on the middle of the scale. I think it means 4 bars or that what it reads, when OK.
But this evening the pressure was slowly raising to just
1 bars, just enough to let the lamp go off. I stopped and checked the oil level with the dipstick and the level was OK, just 1 or 2 mm below the "normall" marking. After a second start the oil pressure was still that low but when i opend the oil filler cap on top of the engine I could clearly see that the oil is flooding the cam shafts. It seams that there is pressure and there is no noise from any bearings or valvetrain. A thing I notised is that it takes 5 seconds for the oil pressure to drop from 1 bars to 0 bars.Is there a problem with the Oil pressure sender unit? Has anyone out there had the same problem?
