SILVER Star
I noticed that my FJ62 was reading lowish oil pressure, hovering around a 1/4 way up the gauge. I had another gauge so I thought I would do a quick swap just to see if it is the sending unit, also had a extra gauge to try (pressure gauge tester was on its way). Anyway, I noticed when I pulled the rubber boot off of the sending unit that the connector was off of the terminal, so I thought, hey that's my problem. Hooked everything back up and the oil pressure was through the roof, tried 2 sending units and dash gauges, all the same, high pressure. I got my mechanical tester and got these readings, 60 psi at idle and 70 at 4000rpms.
So, according to the FSM it is the oil pump relief valve,
So I got a new oil pump relief valve, spring and plug. (I found it interesting that it is made in the US)
Is this the only possible scenario? I am going to drop the oil pan and change the valve but I'm a little concerned that this will not correct the problem. I don't want to have to drop the oil pan again for some other oil pump trouble. Any thoughts? I appreciate any input.
