Is this a ground issue? Oil Pressure Gauge...

[PaulFiveOh]

Here is a weird one for ya.

My engine is for sure 100% grounded perfect IMO...(2 Gauge wire from the block to the neg)

Issue: Oil Pressure Gauge bottoms out 95% of time that engine is running. It bottoms out in a manner that I am sure that it is receiving no signal.
It does this when I am giving it ANY throttle.
When I am not giving it throttle (regardless of rpms) the gauge reads normal oil pressure.

Any ideas?

Probably a bad sending unit.

Probably a bad sending unit.

That would be my guess also 20.00 at autozone and about 5 mins to install. Make sure you put some thread sealer on it before you put it in
