what is your oil pressure when normal driving.

mine tonight was spiking almost 90. i saw it hit about 90 and let off, i dont think ive ever seen it hit that high. granted i just got my car but i thought it was a bit high. my car is untuned so i dont know if thats the problem? any input?

 

high oil pressure isn't a problem. Low oil pressure is.

 

I don't have an oil pressure gauge.... where did you get yours?

^I have a blitz dc2/

 

mines kinda wierd it will start at bout 35psi then bout 10 mins of drivin it will jump to 75 and bounce up and down from 75 psi to passed 100psi thats the highest my gauge goes its an auto meter cobolt by the way oh yeah thats not a cold start either that all the time even at normal engine temp at a consistant speed of 80mph its stays at 65psi

 

Where do you have the sensor mounted? I suspect the variations in pressure are when the thermostat opens and closes for the oil cooler.

Well if you go to 42 draft designs you can basically see the setup there. ^^^^

 

i have the autometer nexus guages. ( oil, fuel, boost, nitrous). i was just wondering because ive never seen it go higher than 80... but ive also had this car less than a week, it isnt tuned, so i wanted to make sure i didnt mess anything up.?

 

oh yea mine is when the engine is fully warmed..

 

You will see the pressure go up and down if you used the fitting on the oil filter housing.. Typically it jumps when the oil cooler thermostat opens and closes, there's a large pressure drop when it opens, and when it closes, pressure will rise...

Sometimes very high pressure is an indicator of some sort of restriction, but it doesnt sound like it on your car.. When was the last time you changed your oil? Some filters (and some filter housings, I'm not sure if ours has it) has a pressure bypass if the filter gets clogged for any reason..

Since you don't say where your oil pressure sender is tapped from, I can't say if this is relevent, but if its tapped in the oil cooler line (or the fitting for the line), then you will see the pressure rise and drop regularly, when the engine is up at operating temp or slightly higher, it should open and your pressure would rise on the gage.. Of course, if that is where it is, you should move it.

I don't have a oil pressure gage in my car so I never personally experienced this on the car.

 

Mmmm, maybe. It was sometimes a problem on DSMs once people started removing balance shafts. Sometimes the turbo seals suffered on Garretts.

 

i do know my car does need an oil change for sure! i just hit 3K. maybe that will help then? i just dont want to blow the damn thing up already!!
