Question about 1986 Jaguar XJSC

1 Answer

Oil gauge fluccuates,while driving. Indicates zero when stopped at traffic light, then gradually moves up as accelleration increases. The only time I get a normal oil pressure reading is at start-up. Dip stick indicates oil level is correct.

You should have a manual oil pressure test done but this condition idicates the oil pump is weak or the high pressure bypass is sticking open.

What causes oil pressure to drop to zero but goes with accelleration


If your oil is full, it's most likely electrical. If it's not electrical, then it's most likely something like a crack in the pickup tube, sucking air if I had to guess.

You have a sensor that controls this. It is a temp sensor. It could be called something else, but it is a sensor that measures your engine temps. It would shut the vehicle off if it is not working properly.

Low oil presure


perform a master oil pressure test. this is done by removing the oil pressure sending unit and installing a oil pressure gauge. if the reading on the test gauge is ok, the sending unit needs to be replaced. if the pressure reads low on the test gauge, there may be excessive bearing wear or you may have worn valve guides. good luck!
