So I am having issues with my oil pressure, noticed while driving home that it was dead empty, as i was pulling over it jumped back up to normal range and from there it began to go back and forth. I did have my timing chain guide break and i just replaced that today, driving the car and noticed it still doing it. Pulled over and sat for a second, started driving again and from 1st to 3rd gear it held good oil pressure readings, once i went past 3200 rpms or would go up to 4th, it would drop again dead empty. Does anybody have any ideas as to what this could be? Anything helps, thanks in advance.

The oil pressure gauges in these cars are essentially dummy gauges. Basically what that means is the gauge will read at a certain point which is a little bit past middle towards the high, when there is 7 or more psi of oil pressure. And when it drops below 7, it will read nothing. Now generally speaking, you will know when your car has 7 psi or less of oil pressure because that is VERY low. Is it knocking at all? I would think just by what you said there is something wrong with the oil pressure sending unit, which is an easy fix.

no knocking from what i can hear, nothing out of the ordinary. Going to take it to get an oil pressure test as well as changing out that sending unit, that's what im thinking also. just hoping it isn't the oil pump

The oil pressure sender can and does go bad. When this same problem recently happened to me, I found there was oil coming out of the center electrical connector. Replacing the oil pressure sender is cheap and easy enough to do for pure diagnostic reasons. Consider trying this first.

if you aren’t hearing anything horrible and it’s running strong , I think your oil pump is just fine. Let us know what it ends up being.:rock:
