oil pressure question
I just sold my 02 C5 and the buyer called with a question. The dash oil gauge shows 80psi (which I believe is the maximum for the gauge) and the digital reading on the dic is 131psi. Is this normal? Thanks!

Do a search on it and you'll come up with a lot of information...personally I do not have first-hand experience with this as mine hasn't gone bad.

My gauge had similar readings until I replaced the oil sending unit. I replaced the sending unit without cutting a hole or removing the intake manifold, but it was a major PITA and there was quite a lot of swearing involved. If I had to do it over, I would remove the intake manifold.

Purchased two pair at Harbor Freight for $15.00 Sure makes many jobs a lot more easy.

Replaced mine as well. There is a great article on here somewhere that lists the parts needed to install the sensor on a remote mount. Since I have a FAST intake, this is the best option since clearances are tighter. So it is now on a 10" braided line and resides under the driver fuel rail cover. If ever it dies again? 3 minute swap.

Removing the manifold isn't that big a deal. Hardest part for me was making sure the little vacuum line on the back of the manifold was plugged back in when reinstalling. There isn't much slack. Do yourself a favor, go to NAPA and pay $10 more and get the brass body sensor.

Just did one of these last night. I do recommend to replace the intake manifold gaskets also if you go the remove intake route. As the youngest C5 is at least 11 years old they could use replacement.
Also if removing the intake, clean all debris from it before dissasembly. After the intake is out clean the valley area also. A lot of crud gets in these areas.

It cost me $340 to have my oil pressure sending unit replaced, at a small town GM dealer, after I missed the 80 psi of oil pressure with the engine not running, when I bought the car. The oil pressure gauge was pinned at 80 all the time.

Mine went the first yr I bought mine 98 with 36k mileage while replacing I also put in new plugs and plug wires. Figured get that all done while I was working on it. 2 months Prior to that my thermostat went, replace that and the hoses. Right after I purchased the car I took it to a shop had all the fluids and filters changed including trans and rear, put new brakes and shocks the previous owner bought a new battery for the sale. Now just enjoy it! Beside oil and a set of tires due early next year I should be good for another 50-60000 miles before anything else needs work

Read the posts, gather part and tools. For a mid level diy'er it's still less than a 2 hour job pulling the intake. Relocate it while you're in there. Posts on everything you need for that also.
