Hello Dewayne. There are several threads on this very topic and a couple different options on how to repair. Very common issue with our cars (sadly). Conduct a forum search on "oil pressure sending unit" and you will get some "light reading" on the subject. Good luck. -Glenn

Go to Google, type in "C5 oil pressure too high", or "C2 oil pressure reads 130" and you will see many options on how to change your sensor, even relocating it so that it can easily be changed in the future. The Google search will refer you to Corvette Forum posts. It's unusual that you have been a member this long and haven't seen all the previous discussions, there must be a thousand.

Yep, you're in for a treat if you fix this yourself, or a fairly costly repair if you pay someone to do it. You need to move (not necessarily remove) the intake manifold to get to the sender. My father and I (neither with any formal mechanical training, but capable DIYers) did this on his car earlier this spring and it took us about 2hrs. If you do routine maintenance yourself (fluid changes, brake pad replacements, etc) you can surely do this yourself.

Moving the manifold seems daunting, but it's just turning a wrench. As mentioned by others, do a search and you'll find detailed instructions on this forum. Corvette Fever also published a DIY article on this quite some time ago; http://www.corvettefever.com/techart...l/viewall.html will show you insructions and detailed pictures for every step of the process. About the only tool you're probably going to need to purchase is a big socket to fit the new oil pressure sender; so buy the new one and get a non-impact socket to fit (the side-wall of a socket for an impact wrench won't have adequate clearance.) Corvette Fever rates this a "2-wrench" job on their difficulty scale, or "Beginner - basic tools."

As long as you (or someone) is in there, you should consider replacing the passenger-side A.I.R. check-valve as well; with an 11-year-old car with 100k+ miles, you're due for this part if you haven't already replaced it. This is another common repair which also requires moving the intake manifold. Do a search for P1416 on this forum. A genuine GM part will run you about $30, and an aftermarket about $15; but the real cost is getting to it.

Good luck.

Its NEVER a good idea to just slide the intake manifold forward!!!

If you ever remove yours and see all the DIRT, SAND and trash that finds its way in between each cylinder intake opening, you will be amazed and shocked..

You run the risk of getting that junk in the intake port AND between the O ring seal and head.

DIRT AND SAND:



Slide that one back and see if the intake gaskets seal!
