Oil Pressure Hits Zero And Stays There- JGC '96
CHECK GAUGES: Zero Oil Pressure reading-
First had this problem on my way back home, I stuck in traffic, in the
middle of the summer. It was a hot day, and I had been driving for 40
minutes. I was at 4,000miles with my oil, which is 5 part synthetic,
1 part Lucas.
I told my mechanic that I though the problem might have to so with
dirty oil, because I'd never let the oil go for that long and I'd never
had this problem before
Mechanic changed the oil and the sensor. Nothing Happened. The light
would come on after the car warmed up for a while. Replaced the Oil
Pump- No Dirt in the screen. No change except for higher pressure on
Start-Up. Used to be 40-45, now is 50-60.
The problem used to happen after 20 minutes. Now it happens within5
minutes. In addition, the pressure used to go back up with
acceleration, but when it hits Zero, it stays there.
The mechanics first suggestion was to pull the valve covers, and
replace them, after cleaning out the RETURNS. Now he says he wants to
have the CPU reset first, but that costs $100 and may not solve the
problem.
What's the deal?

First thing I'd do is put a real mechanical oil pressure gage on a 't'
fitting and see what the engine is really doing. If it really is
dropping to zero after it warms up, about the only thing that could do
that is a bad oil pressure relief valve on the oil pump. That is a drop
the pan job, a nasty project on yours.

Re: Oil Pressure Hits Zero And Stays There- JGC '96
There is no engine knocking et al, so we think the oil pressure is
fine.
My mechanic told me it shouldn't be the oil pressure relief valve but
he never tested it. I've seen the dropping of the pan performed, by my
back-up mechanic who replaced the oil pump, but did nothing else.
Are you saying that the valve cover/gasket and the cleaning of the
"RETURNS" wouldn't fix this?
Should I cancel the $100 appt with the dealer to reset the CPU, or just
let them find out what the real problem is, and bring it back to my
mechanic to do the work. I have a good mechanic but he's can't figure
out the problem or he's too lazy too. I do trust him to do the work
though. He changed out my exhaust manifold before.
This whole ordeal, along with countless other bigger issues I've had
with cars have made me want to become a mechanic but as for now I can't
do anything but change the oil.

Re: Oil Pressure Hits Zero And Stays There- JGC '96
If you are sure the oil pressure is fine then it is most likely a
problem with the gauge or sender or circuits. You did not mention
checking the gauge itself and the wiring.
