Oil pressure gauge
gwcrim:
I'm getting erratic readings from my factory OP gauge. The engine has about 2300 miles on it and never makes an unusual sound. When I go around turns or under hard acceleration, the pressure drops to nearly zero. I really doubt that the pressure is dropping and I'd like to eliminate the electric gauge.
Can I retrofit a factory mechanical OP gauge into my electric gauge hole?
JohnnyPopper:
First find out if they made one for that year.
Sounds like you have a grounding issued.
There is a product called DeoxIT D5, it is a electrical contact cleaner, I would use it on your connections.
bd:
Verify there is not an oil delivery problem! Connect a valid mechanical test gauge and confirm engine oil pressure during an actual road check.
gwcrim:
The truck is a 1980 and they stopped mech. OP gauges in 1978 or so. I agree with BD that I should verify pressure with a mech. gauge. So if I'm going to install one, I want it to go in the original hole on the dash and leave it there.
Hence my question.
JohnnyPopper:
Look at aftermarket to see if they span those years. I have both 78 and 80, look identical.
What is your pressure reading when you're not terrorizing the neighborhood? 8)
