no oil pressure after.....

gt50blk · 07-18-2004, 05:00 PM

I have 92 5.0 that here in the last couple of days has had no oil pressure once the motor is warmed up. I'm thinking that that I have some bearings going out or my oil pump is junk now. Any idea's?

Hook up a mechanical guage to be sure you are losing the oil pressure before you tear it apart. If you have oil pressure when you start it up then it slowly goes away as it warms up, you may have spun a bearing.

Don't even trust your stock guage for a second. Don't drive the car until you hook up a real guage, and confirm you have low oil pressure.

How many miles on the motor? Stock? common issue at high mileage which then means rebiuld. but yea, the stock gauges can lie at times, or even the sending unit.. test the pressure with a mechanical gauge.
