Oil Pressure High

aconklin · 08-04-2008, 07:04 PM

My oil pressure has been sky rocketing past 80 when I first start the truck up until the engine temp reaches 210. As soon as the engine is warm to 210 it stays between 30 but if I get down on it say around 4000 RPM the needle goes to about 60-70. The engine sounds fine. And my last oil change was about 2000 miles ago with mobile oil. The truck is a 2002 S-10 with about 56,000 miles. Do you think it is a sensor? Or?????

Seems about right to me....mine does basically the same thing and it has 155,000 miles on it

you using 5/30?wt...higher wt will give you more pressure......

aconklin · 08-05-2008, 04:18 AM

yea i'm using 5-30. so with the oil pressure going to around 120 i shouldn't worry about it? Just let it warm up I guess before I take off

Mine doesnt get that high at startup.... first thing in the morning when I start mine it will get right at 80 when I take off until it warms up then it is around 60-65 while driving and around 35 or so at idle.

If the pressure is really going to 120 psi, you could blow the filter housing and loose all of you oil, and make one hell of a mess too. First thing that I would do is replace the oil pressure sending unit. If it does the same thing with a new sending unit, you may have to replace the oil pump - not an easy job.

wow 120 my 95 hits 80 at start then stays at 60-65 it has 160,000 on it

BAD. Shouldnt get much past 60. 80 (correct me if incorrect) is the end of the gauge reading? The only two things that can cause runaway pressure are stuck bypass piston in the pump (has one?) or a restriction in the pump output. 5 - 30 is thin, im using 10-40 at 210000 miles and pressure goes to 60 -ish cold.

Yeah, my gauge only goes to 80 so I wonder where he's getting 120 from?

Maybe we've been punked?
