If any of you have a aftermarket oil pressure gauge on your 2004 Cav. could you please let me know the pressure. I just got mine hooked up yesterday and when it's cold it reads 100 pds. Warmed up and on idle it reads about 75. I believe this is to high. I hreally hope it's not the gauge cause it was a bitch to put this a and 2 other gauges in. Do you think it can be the oil pressure sending unit? The gauge is eletrical. And the volt meter gauge reads exactly 14, I think that's normal. If any of you had this problem, let me know if I can fix it. Thanks
I have an aftermarket oil pressure guage and mine reads that high at initial startup and I have heard them reading that high after warm up. How did you ground the sending unit assuming you used a remote mounting kit like I did? Mine reads about 40 after warmup. I had to rig a ground setup because I could not think of anything else to do.
The sending unit normally would come right off the block and use the block as the ground. For mine I know this will sound ghetto but I wrapped a piece of wire around the sending unit and put a pipe clamp around the wire and then ran the wire to on of the bolts on the strut tower. It looks bad and I really don't like to use mcguyverness like that but it works. So let me know how you grounded yours.

On my car, I've got about 75psi when I start it, and it stays up there for about 10 minutes. After it warms up, I get around 35-40psi at idle.
I may not know much about cars, but I know two things....
1) Breaking things is expensive, and
2) Horsepower isn't cheap.
looks like its a comon thing... my oil press does the same... its a mechanical one btw.

its normal thats the pressure is higher on cold start.

Where did you get the remote mounting kit?

I got my sending unit in the block and I checked with a OHm meter that it is getting grounded by just being screwed in. I don't get the McGuyver approach.
My guage reads 75 when cold and drops to 30-40 when hot.

GM manual says 75 PSI min at 1000RPM on cold startup and 35-50 PSI at 1000RPM once warmed up.
hope that helps.

I got the remote mounting kit from autometer.
It seems to me it cost about 12.00
It included line, fitting for the block, fitting for the sending unit.

i dont believe its reading too high.... ive heard the eco has very high oil pressure... thats just what i heard anyway
