Heres the lowdown:
idling at 955rpm
engine cold=normal oil pressure
engine warm=low oil pressure
greater than 1000rpm
engine cold=normal oil pressure
engine warm=normal oil pressure
Diagnosing
Oil pressure switch sending out correct readings. Have checked by removing switch and measuring pressure with diagnosing pressure meter. Also, eliminating oil pump failure.
Recent oil chage slighty increased oil pressure at idling but light still comes on.
Cure
Does anyone agree that my next move should be to remove the valve and spring from the oil pump to check for a blockage. I was informed that this was a common problem for short run sr's?
Any suggestions would be welcome.
The car is a 1989 sr with only 19k on the clock.
