Oil Pressure problems/questions
Hey guys i have a 93' v6 4.0. She takes 5 quarts of oil including the filter. On the 93 the guages have "normal" on them. Before the truck's oil pressure was between r and m and didnt change at all! Now the pressure is up between m and a. I recently switched to high mileage motor oil. I made the switch at least a month before this happened. I stuck with 10w-30 full conventional. My truck does leak alot of oil though. About 2-3 drips after its warmed up and is sitting. My thought is that the new oil is sealing some of leaks and slowly stopping the leak. Also tonight i noticed when my truck was ideling there was a slight tick. Not really loud, but definetly there. Could these to be linked? And why is there such a spike in oil pressure?
