Re: 1996 LT4 Oil Presure Problem

Thanks for the suggestion. I ended up taking it to the dealer. They did a manual oil pressure check and it was normal at idle. So, it looks like there might a problem with either the guage itself or the wiring. The dealer offered to track it for me. They said it could take up to 4 hours to run the problem down. I think I'll live with it now that I know the pressure's actually ok.

When the oil pressure drops, do you hear any lifter tapping?? >It might be a bitch but if you could get one valve cover off >and start the engine, let idle and see if you can see streams >of oil coming out of the tops of the pushrods at the rocker arms. > >You can also put a mechanical oil pressure testing gauge on >the oil pressure port to double check the in-car gauge. > > snipped-for-privacy@vette.net wrote: > >>I have a 1996 LT4.

But without a proper operating gauge, if you ever hear the least bit of tapping or knocking shut that sucker down right there and pull to the side of the road.

Who knows if the idiot light still works if the gauge isn't.
