    Angry LS1 oil pressure problem

    My 98 LS1 Vette usually runs 45psi oil pressure when warmed-up,I was cruising in it last week(not jumping on it too hard) and all of a sudden the oil pressure gauge was burried at 80psi!
    I checked the gauge on the DIC and it read 87psi!
    As I slowed it came down to 70psi but never went below that.
    I drove it again this weekend and it was holding around 75psi and then it jumped to 90! Then 94! then 97!
    I slowed to a crawl and put it in neutral and it came down to 90psi so I limped it home and shut it down.
    What the H is going on? Any suggestions?
    I know I need to get it into a shop but there are slim pickin's where I live other than the dreaded 'Dealership' so I'm wondering how far,if at all,I can drive it.

    I know more is better but I didn't do anything to it to bring it up,it's doing it on it's own.
    And if it goes too high,stuff could happen.

    too much oil pressure is not a good thing. I agree with Sarge, check the sending unit!

    ding ding ding. We have a winner. My buddies 98 c-5 had the exact same thing happen. Easy fix. I took his intake off and replaced it in less than an hour.

    No, not true at all. The LS1 is designed to operate between 20 PSI and 80 PSI, if your oil pressure is higher than 80 PSI there's definitely something wrong with your motor. Like a clogged up oil passage or something along those lines. Not a good thing.

    Sounds to me like the gauge is at fault in this case though.
