ok i finally finished getting the oil pressure guage installed. THe guage goes from 1 - 150psi and is mechanical. What number would be normal for a turboed cavalier and what is it acctually reading. Thanks for the info
well it would actually be reading oil pressure
the pressure should be no less than 10 psi , and can be higher than 100 psi when cold
anything inbetween and your safe
gm states 10psi per 1000 rpm (atleast that is what i remember it being last time i looked)

I'm not sure how accurate that is. I know on a 2.4 when nice and warmed up WOT at 6200 RPM you are between 45-52psi. That would not equal 10psi per 1000rpm's.

yes quoted is 10psi per 1000rpm, however thats a "rule of thumb" and most of the time isnt met in the higher rpms. the 2.4L's oiling system also isnt the best.
on the new 2.4L that i built with the 2.3L pump swap i did 75psi cold @ idle, 110psi @ 2500rpm, warmed up it did 62psi @ idle and around 98 or so @ 2500 rpm and rock solid till redline.

Ouch!! thats alot of power going to waste.Too much pressure just causes the motor to eat up horsepower and puts additional stress on the accessory drive system.
If you can maintain about 45psi+ from cruising rpm up you'll be fine.
at crusing im around 50psi and at high boost it only goes up to about 70psi
does that sound right?

You have a Ecotec so I'm not 100% what they read. I can only account for the 2.4 with stock bottem end.

I'm N/A with my Ecotec...and warmed up at WOT...I get like 80-90 at all times....usually though at idle I may drop down to around 55-70 range.
But like I said I'm only N/A...but maybe it helps you out.

With the Eco, where is your sender hooked up. When mine gets fully warmed up I get between 25 and 50 psi at idle. It's NA and running Mobil 1 oil.
My 2.4 runs about 40-50 at 60mph and from 65-78 at WOT. That is after it warms up. At idle I'm around 8-12 psi. "600rpm"

M. Mathhews. - My sender is hooked up in the stock location. Took out my stock sending unit and put in a T-Fitting in the stock location. Both senders are running off that tee. Where is yours located? I wonder if it makes a difference or not? Did you drill a hole somewhere else?
This makes me go....Hmmmm......

no not really... keep in mind this is taken with 10/30 oil, not that it will make much if any difference... and it'll be fine....

What numbers are you showing at idle and, say, 3000 rpm when you first start? Same question after the engine has reached normal operating temp?
I just built had my motor built(2.4 with a 2.3 oil pump) car was idling running fine at 2000 rpms
but i started to get timing chain noise and now i have no oil pressure
the motor is ok it did not get hurt..
but i have no oil pressure changed the tensioner and still no pressure?
the oil pump was used
Possibly the relief valve is stuck open or some plug (?) was ejected. Don't screw around -- buy a new pump and install it. Your time is valuable too. If you got this pump from a used engine maybe that is why the engine was taken out of service or it was contaminated by debris. Who knows.
