Ok well my car is almost running right i think, and i could really use some help again. At idle the oil presure is at 120, but it was at 60 when it was driving the car befre this month. What could be causeing the oil presure to be so high. I dont get it? Its full of oil and it dose have some strip bolts on the oil pan that i tighten to hard, that i am about to fix, cause it is leaking oil. But i still have the 120 oil presure, got any idea beside the OPR. Cause i am faily sure if it was a new one when i put my motor back togeather. Thanks Marc

 

Sounds like a bad Oil Pressure Sensor!

 

the thing that plugs into the oil pan? That has the white spade on it?

 

It has those 3 screw and the go to the oil pan? I cant find it in the book!! ANyone?
am i thinking right?

 

i though that was the oil level sensor, i would think the oil preasure sensor would be somewhere that oil flows and doesnt just sit. Just a thought

 

The oil pressure sender is under the oil filter (which is why it usually get dirty from oil dripping and dust).

 

so its the one that is fat and has a spade or the one to the left or it and just has a spade?
Thanks

It round. About 2 inches in diameter. It has a rubber grip. It screws onto the block, near the coolant temp sensor. Sorta below the oil fiter, above and to the right of the spark plugs.

 

so i should replace this or what. or clean this. What i should look for.

Clean it first and see if that helps. If not, replace it.

 

My oil pressure went from almost not registering to 120 cold and a little above 60 warm when I switched from 10W30 to 20W50.

 

this also sounds like a dirty/bad sensor - I run 10w-30 all the time and get over 60 psi at idle cold and 60psi at 2000rpm hot

 

Ya im using 20w 50.

 

so maybe after some warm up it will be alright? I hope!!!

 

ya, i didnt think of this marc - brain fried

usually the connetion is just dirty so try that out first...thats what was wrong with mine when i first got the car.
