Well this morning on the way to school my check guages light came on and my oil pressure was sitting on dead zero. I stopped immediatly and checked my oil and it was full. I had it towed home cause the oil would not leave zero. I drained the oil and it was perfectly clean. Maybe it is the oil pump or the sending unit or something else. I also did LT headers like a week before if you think it might have something to do with it. Any help or suggestions would be appreciated.

 

Worn oil pump.
Loose or disconnected pickup.
Open pressure release valve.
Clogged pickup screen

or like U said the sending unit

 

Well if it was just at zero and did not move at all then it is probably the sending unit like you say. Since the oil is nice and clean and if you didn't hear any weird noises, thats probably what it was.

 

I would try that first. Always go by the K.I.S.S rule!

 

if its not the oil sending unit, i woud jast your motor up and take the oil pan off and see if you spun barings those go out if your oil guage hits zero, i know this too well

 

same happened to me, was the sending unit.

 

Well i found the culprit and the oil pressure sending line was crimped under the valve cover. I cut out that part of the line and replaced it with new wire. Now the oil pressure is pegged out and i dont know whhat to do now. Any suggestions????

 

If it's pegged out then you may have grounded it out somehow when you replaced the wire. I don't remember exactly, but wasn't it a two wire setup on the oil pressure sending unit???

 

I got it fixed! the wire going into the clip of the sensor was not in there to good but now it is and i have a good reading of oil pressure

 

 

Nothing like a bad sending unit or wire to give a person a heart attack. At least that is all it was.

 

Just to clarify for those that may read this thread later, the crimp you found on your wire was grounding out the gauge. That caused your zero reading. When you "fixed" the wire, you left it open to the sensor. This caused the gauge to be "pegged". When you finally got it connected, all was well again.

There is only one wire on the f-body oil pressure sending unit and it goes to gauge.
