Oil pressure suddenly went up !?
By Martin Micheelsen - 01/10/2003 3:05:16 AM; IP 66.135.226.87
2 days ago I replaced the valve cover gasket on a very tired 390IP in my 69 Cougar. The gasket was old and the workspace is tight so some cork chips probably went down in the engine. The wiring harness that included the wire for the oil pressure-sending unit was tugged at in the process. It still appears to be on right. After the gasket was replaced the oil pressure reading had increased by approx 35psi across the range and now shows approx 90 – 95 PSI at 2000 rpm. Tonight I replaced the oil filter with no effect - the old filter was about a week old. The oil is 20-50. The engine runs normal and as well as can be expected for a tired engine. There is no clatter of lifters indicating that a restriction in oil flow is starving the lifter galleries. What is most likely to have caused this ? The engine is slated for a total rebuild in April. If it isn’t necessary I would really prefer not to have to do work that is more involved than the sending unit or oil pump between now and April. The car is my daily driver. Any advice will be appreciated.
