hey guys. heres the thing. i started my truck (4.3L 1999 GMC sierra) and noticed my oil pressure gauge went to 0. i shut it off and looked around and found most of the oil on the ground. i found it was the o-ring on the oil filter had blown out a bit. (good mess).
well, i took the filter off and put the ring back in and re-installed to get me to the store to buy a oil change that was needed anyway. now it seems to be working ok as i have been running it normally for 2 weeks now but i think the pressure is still high so i dont take my eye off the gauge and its kinda nerve racking. the guage is in Kpa (canadian truck) not psi and it holds steady at the think dash between 275 and 550 when driving and just below 275 when idling.
im not sure but i think normal it ran just over 275. i know the sensor or sending unit commonly goes on them but that dont explain the o-ring blow-out. is the pressur ok or should i get it checked out
