View Full Version : 91 vert oil pressure issues
06-18-2008, 12:32 AM
Ok right before I went on a two month deployment, my oil pressure gauge went all over the place. 0 to 100+psi. Didn't matter the load on the engine or anything like that. It finally settled to the top peg (100+) and hasn't moved. Even when the car is off. I cleaned the sender unit connection and the ground, but that is it. I figure it is the sender unit, but I haven't chased wires or voltages yet. So if anybody has any ideas let me know. I have about three weeks till I disappear for month again to try to get it fixed.

It is the sending unit. Mine did the same thing after the engine swap. When I took it out I noticed a slight ding in it, that is all it takes for it to act up.
Unfortunately for me, however, I left it connected during testing and initial start up. The gauge was pegged out and finally, it actually broke. So now I have an Autometer sender in the factory location (using an adapter from BSPT to NPT) and the gauge is above the stereo.
