!!new Startup/dropped Oil Pressure!!

[Boosted04Z06]

ey guys, just fired up the ls6 for the first time tonight, SOUUNDED SOO GOOOD....I let it run for a couple minutes and the shut it down to fix a couple leaks, then started it again and let it run for probaby ten minutes. I have an aftermarkte high volume oil pump from lingenfelter, and I noticed that my oil pressure was reading betweent 118 and 130!! I thought it would go down as the engine warmed up, as I backed the car out I saw that my ins. cluster says service engine soon, and low and behold I have 0 oil pressure....what could be wrong??

sounds to me like the excessive pressure messed up the sending unit. Try putting a mechanical gauge on it to see what kind of pressure you have when the car gets hot.

Dustin,
I agree with Rob. 118-130 is way too high. The stock oil pump relief lifts at about 75 psi to port oil back to the pan to protect the engine from excessive oil pressure. I'd ask what the relief is set at for your aftermarket unit. If it is as high as 130 psi, I think that is very excessive.

Its possible that as Rob guesses that you have damaged the sending unit. Only way to know for sure is a mechanical unit.

Good luck sorting this out.
