I'm with sonoma, From 1000 rpm up I read between 65 and 70 psi. At idle drops down to 40. Initial cold start up gives me 70 solid and when it drops down will sit at 50 at idle for about 10 minutes, than drops to 40.
i dunno about the 4 cyclinders but my v6 my g/f dads v6 and the guy that lives 2 doors down v6 run at 60 on cold start and when completely warmed up drop down to 25 at idle...when i first got my truck i thought this might be a prob so i asked the mechanic and he said hes never seen one that wasnt like that.....tbi anyway
What is the problem is the gauge off from its original idle oil pressure value? Or do you not remember what it was at idle prior to your gauge switch? Mine is still very high at a cold idle 60 to 70 pounds. But at operating temp idle it's more like 35 to 45 pounds. I am about to go to the store and I will pay particular attention to oil pressure. So if I respond again my memory is whack. And to be corrected soon. I do it all for my S10 driver friends whatever you need and I can offer. Blow jobs are definately out however!
Ok heres the update, first let me mention what I got. A reg cab 2.2 X w/ AT and 6878 mi. But the idle values in neutral should be the same. It is now raining in Henderson with light wind and 37 degrees f approximately. When I started the truck oil pressure reached 81 psi in 3 seconds. When I got back from store neutral idle was 46 psi. And dropped to 44 psi when I put back into drive. It idles at 900 rpm in neutral hot or cold too.
I know I was attempting humor. I get crazy please boot me from forum. I have no self control once lit(boozed up)! They booted me from the 1911 forum because their a bunch of natzis and communists over their. And it pissed me off to no end. To ridicule people and insult people like that. I am trying to cope people and you are all fantastic as far as I have seen. I also would not be offended to be ousted!
well actually it taps like a b!itch when i first start it up for like a minute.....i noticed the same tap on some of the vans at work w/ the 350.....but when its tapping the oil psi is like 60 or so...i dunno....i'll worry when it stop running or taps when its warmed up.....
CynicX you should see sticky lifter posts. The hydraulic lifters get sticky after many miles. But under 100,000 mi is abnormal for this problem. Oh its nastalgia day and never mind. I just know my engine will scream and put out its best and I do put it to the test sometimes like today.
Right from the GM manual, my 2000 2.2 should have 65 psi at 3000 rpm. That's assuming using the recommend oil. I run synthetic 5w30 and it's a bit lower at idle but runs at about that once you rev it up.
