Check this out: oil pressure gauge, possible issues?
Info: 01 7.3 116k miles, auto trans.
Lately i've been annoyed by the oil pressure gauge in the dash. When I go out in the morning and start the truck, it turns over and cranks up just fine. It'll run for 1-3 seconds before the needle on the oil pressure gauge moves and the low oil pressure light will stay on with it. It's been getting progressively worse over the past few days also. Today I decided to try something so here's what I did: I would start the truck, let it idle for a second, then shut it off. I did this 5 or 6 times and it got to the point where the oil pressure needle would move before the truck would even crank up. I also noticed that the tach needle would move up a few hundred RPM's. I kept starting the truck over and over and each time the needle would jump up to normal oil pressure before the truck started. So here's my question, what does this problem sound like? LPOP? The gauge? Or something else? I've had help from one guy on here (thanks Nick) and i'm going to install an oil pressure gauge to see what i'm getting but i'd like to know if anyone else has had this problem or knows of a 'fix'.
I will also mention that the truck has 0 problems running, doesn't seem rough at idle or anything. Still maintains 15-17 mpg and she seems fine.
