CUMMINS oil pressure????

Nuts · 03-30-2011, 09:17 PM

I have a 95 12V with only 222,222 miles and last week I noticed the oil pressure gauge would randomly drop then pop right back to where it should be. I changed the oil thinking maybe it was just thin but that didn't help. At idle and when I'm driving it usually stays well over 40, but if I "blip" the pedal it drops pretty low sometimes to "0". It seems to drop off when the convertor locks up too. All this only happens after the truck warms up and the gauge always comes right back up. So is it just a propblem with the gauge or sending unit, or is my motor about to lock up? This weekend I'm putting a mech gauge on it to see, but wondered if anyone else has had this problem...
