High Oil Pressure...

I got in my vette yesterday and all of a sudden the oil pressure is hanging out in the high 70's at idle. Driving home I almost pushed it into three digits. I turned the car off and then on again to see if it was a glitch. Also, the DIC and the gauge had the same reading.

Anyone know what causes this?

There are a lot of posts on this common problem. The only ones who seem to have the problem reoccur are the ones who replace the bad sender with an AC Delco.

There is a vacuum line that controls your AC doors. Put an extension on the line to make it easier to hook up after you get the manifold back in place. You do NOT want to use the genuine GM part made in Mexico with the aluminum housing. Use aftermarket with a brass housing for longer service life.

This is the biggest known problem on the C5.. Don't get another from the dealership or you will be replacing it again

Anyone feel there will be a recall on this someday?

I doubt it, because it's not a safety issue, just an annoyance.

Will this tool work to release the fuel line on the 99 disconnect?

With my ported oil pump, I'd be worried if it didn't hit 70 psi.

Stock pump runs a wee bit lower.

Here's the fuel line removal tool I got at NAPA. Most any parts store will carry one version of this or another.
