Oil pressure woes
Oil pressure woes
I am wondering about my oil pressure. I have a 02 with 75k miles.
I have never noticed this before, but my oil pressure gauge under accel is gaining pressure, like from mid to the last tick on the gauge. Isnt that a tad high? Also I just changed my oil and filter tonight and for the first time, When i unscrewed the filter, it started pouring oil out, I hadn't got it unscrewed all the way yet. Was there a filter failure or blockage possibly? Or is it just thinking bad thoughts when there isnt a problem? I changed oil and filter and put in my 3 gal's of Blue, and I started it up and let the oil circulate then slowly rev'd up to 2k rpm and the oil pressure slowly raised up with it.
With gas prices and other things ... im paranoid something else could go wrong on the truck that i just cant afford to fix atm.

i had a similar problem on a 91 ford with the 7.3, and it was a bad sending unit. We could not find a replacement that worked right either, so we installed a mechanical gauge. No problems with that for a year, and truck still is running with 250,000. i would reccomend trying that temporarily first.

put a mechanical gauge on it
Take the plug from the oil filter housing next to the turbo supply, and read it there to eliminate the console gauge, and know exactly what your running, then diagnose the console out.
And technically, the higher the engine RPM the higher the pressure should be.
It's disconcerting to have the gage act funny all of the sudden- my 96 just did that same thing. The gage stopped working- dropping to 0 intermittently and such, after replacing the sending unit the gage now varies in reading (it used to be rock steady at all times), but it's within the suggested markings).
I'd recomend doing as DetroitDiesel71 suggests- bypass the sending unit all together and see what's really happening with the pressure.

All the trucks since late '97 have had a "calculated" guage. Get yourself a manual guage so you KNOW what your oil pressure is. Not a "guesstimate" by the computer. Mine reads 25 hot at idle, and 75 at 2000 rpm's hot. Cold it is near 75 at idle and 80 @ 2000. Not even close to what my factory guage reads!
