Sudden, complete loss in oil pressure?!?!

well when mine broke it went to zero. THe internal wiring broke inside the black plastic place.
1995blacktattop the rule of thumb i about 10psi for every 1000 rps so your OP is within desired range. I have never personally seen it that low on a f-body though.

well by that i'm not too low then because at 1000 rpm's im at 20 in that vid. my idle is ~ 500-650 and approx 10 psi if the gauge is right and i'm pretty sure its reading lower than the oil pressure really is.

do these cars have an oil press idiot light? I dont remember as I dont have a a 4th gen just the engine. If so when you lost oil pressure the light should have come on as well if it didnt its more then likely a faulty opsu but if both came on then that means you are actually losing oil pressure. The best thing to do would be to hook a mechanical gauge to it and run it to see exactly where you stand. If you have good pressure using a mechanical gauge then I would replace the opsu while it is out and make sure all wiring is clear of the headers. If the opsu and gauge works off of a ground=0 oil pressure then a burnt wire contacting something metallic that is connected to the engine will ground the sensor and the reading will be zero but im not sure how these sensors work ide have to get out the manual...
