I noticed this evening that my low pressure oil pressure was much higher than normal. I have a LPOP gauge that typically reads 12 psi or so at idle. This evening I was seeing 75psi with a warm engine. Every little acceleration pegged the gauge over 100psi.

The factory non-functioning gauge says that everything is normal.

How concerned do you think that I should be?

I am about due for an oil change. I was thinking that I would change the oil and filter as soon as possible and temporarily plumb in my mechanical gauge to see if the high pressure reading is real or not. I replaced the stock LPOP about 3 years ago with a melling and everything has been golden up until now.

Any other ideas for things to check?

 

What brand of gauge. I'm assuming its aftermarket. I've had 2 sending units go bad for fuel pressure and when they went they were indicating high. Might not be actual oil pressure

 

The gauges that I have are isspro ev2's. They've been installed for about 5 years.

 

Sounds like a sensor to me. Do you have any other EV2 pressure gauges? Many of the sensors are 0-100 PSI with a range of 0-5 volts output. My Fuel pressure gauge doubles as a boost gauge, I just installed a switch to select the function I need at a given time. You can take a fuel pressure sensor and swap it to the oil pressure port.

 

Hit up Tugly's magic kingdom (Harbor Frieght), get yourself a 18" flexible grease gun hose, a 0-100 liquid filled gauge, a 1/8npt coupling(to connect hose to gauge), and then find yourself a hydraulic store and get a #4orb X 1/8npt(f) adaptor... Then plumb gauge setup to the hpop resivoir plug and fire up truck

 

misread.....nevermind

 

Owe gawd....
