Oil Pressure drop on open throttle?

[kidmet]

Anyone know reasons that my pressure would drop when reving in the driveway? Same happens when driving and you press the gas. Don't want to damage the motor, so I haven't drive much at all. A couple houses maybe.

Probably should try and detail the problem more. Sounds like something is stuck inside one of the oil galleys. Check your oil pan.

Something is definitely going on. Your oil pressue is doing the opposite of what it should do when rpm's raise.
What is your oil pressure like at idle?

Ordered a new oil filter housing as maybe the sending unit is bad? Can't hurt. Going to change the oil when that comes in and see where I'm at. Here's a video

Just to be clear, oil pressure is RPM-dependent, not throttle-dependent.

What are you basing this drop on - stock gauge or aftermarket gauge/sensor?

The oil pressure gauge never went above zero throughout the entire video, and the light comes on everytime it's off idle. I would say it's unlikely that both sending units are bad.

Is there a dent in the bottom of your oil pan perhaps?

I'd get a oil pressure tester (mechanical gauge) and see what the oil pressure readings are. A damaged or plugged up pickup may cause your issue.

Stock gauge... I'll look into a new oil pressure gauge. Also, where would I find and inspect the pickup? I'll have to look at the oil pan. My first reaction was yes, but now I can't remember.

Yes, that's what I meant. sorry about that.
