Question about Cars & Trucks
My oil pressure on my 1988 ford ranger v6 2.9L climbs slowly to the "H" at the top of my gauge. It began doing this recently. I have yet to replace anything. I will be replacing my sending unit and oil filter tomorrow. I am curious if that does not do the trick what else may be the culprit if these do not fix my issue. I'd appreciate any feedback and will post my results with each new part I try.

There is a pressure release valve alongside the oil pump in the sump.
Ensure you use the correct grade of oil.

I don't know if this will help anyone, but i had a issue with my jeep running hot and check engine light coming on as well. After alot of trips to different shops - the last one found that there were two senors in the engine for the fan that need to be changed. Everyone would aways fine the one up top but not the second one. After that, have not had any other problems like it since.

Was the sending unit an aftermarket part?We like to install the original part back into most vehicle, but because of people price shopping, this can cause some issues. If the switch is working properly, the gauge should rise as the engine RPM's increase as you stated. With the key on and the engine off, disconnect the sending unit wire and ground it. The gauge should go to the highest reading, and that checks the wire, and the gauge. I suspect that the sending unit is failed or not the proper one for your vehicle.

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.
