Well for the last week or so my oil pressure has been running about 10 lbs lower than normal (about 60 lbs at 70-75mph). I changed the oil a couple of days ago and today while coming to work it shot back up to normal (70 lbs at 70-75mph) for about 10-15 miles then went back down to 60 or a little lower. So what's the deal anyone experience this before and will I have to tear into her to change out that pump. If so its really going to cost me some bucks cause if I've got to go in I might as well change to a different cam while she's down and also some stiffer springs and such. Well what do yall think should I worry or just blow it off ? The truck has 162,xxx miles on her so maybe its time. I just don't have the cash right now to work on her...Zed

 

With oil psi like that you shouldnt worry about anything. Espically with that amount of miles on it, thats good.

 

Cool deal I'll still keep an eye on her though. At what psi should I consider critical...Zed

 

This is what GM says

Oil Pressure (Minimum--Hot)
41 kPa at 1,000 engine RPM

124 kPa at 2,000 engine RPM

165 kPa at 4,000 engine RPM
6 psig at 1,000 engine RPM

18 psig at 2,000 engine RPM

24 psig at 4,000 engine RPM
