Super high oil pressure!
Alright I drove to work today and couldnt help but notice that my oil pressure gauge was pegged the entire way to work. I turned it on the DIC and it steadily climbed all the way up to 128 PSI! Da heck?
I dunno if the pressure was actually that high or if the sender unit is malfunctioning. Ill find out if it does it again later today when I go to lunch/leave.

Go to the top of this page and click on tools, then tech tips, then C5, then look for the topic oil pressure sender replacement.,.,,

Re: Super high oil pressure! (Patches)
OK good looks like an easy/cheap fix. My previous car (nissan maxima) also had oil sender issues (and it was the same size too). However in that car, an aftermarket unit from the local auto parts store was recommended over OEM. I wonder if this is the same case here...

Re: Super high oil pressure! (Evil-Twin)
When I first start driving my vette and its cold, the oil pressure usually goes up to about 60-70psi then after a while drops down to about 40-50 during cruise. Is this normal? It seems a bit high at 60-70.

Re: Super high oil pressure! (Patches)
That's normal OP. I have a p&p oil pump and my pressure runs even higher than that.

I wonder if this is the same case here...the part number on the box in the tech tip is the lastest upgraded sensor.... the picture of the sensor on the tech tip is the old one.. and just for a visual reference..

Re: Super high oil pressure! (FunDriver)
So I called the local chevy dealer for this part, and they actually pointed me to the cadillac dealer down the road. So I go there, get the part and the guy said $55 but ill give you 10 off. I figured it was $10 off but it was actually $10% and plus 5% sales tax = $52 :mad Gm parts direct wants $35 for it shipped, dang o well I have the part I might as well go put it in.
So then I went to play the onstar game while sitting in a deville and I lost :mad

Re: Super high oil pressure! (eRiCdWoNg)
Holy crap! The instructions in tech tips is WAYYYYYYYYY abbreviated. Dang, what a chore to get that thing out. I just took a break from alot of swearing, moving the intake manifold is a pain in the butt. You have to disconnect alot more wires and lines then it had stated. And theres this one line under the TB that is coolant, and when you pull that coolant goes everywhere! This better fix the prob or I'm gonna be even more :mad Now I'm tryin to find way to clean out all the crap thats between the intake and the block without dumpin all the grit and sand down the intake holes! :eek:

If you dont have basic mechanical savy you should not be messing with your motor.. MMany people have emailed me with their success on fixing this problem.. And their thanks...sorry if it was not good enough for you...and your expertice.
FYI although ive never done any internal engine work I have however rebuilt transmissions (by myself) and pretty much any other bolt on component imaginable, on various cars and motorcycles. This was the first time for this one for the c5 and the sensor is quite buried. Again not bagging on your article but I felt as though there were some things that could have been added. and again, I know you wrote the article and i've very greatful for that. And yes, it did appear to fix the problem. :cheers:
