I get in my car this moring to go to school. She starts up fine and drives normal..until about 1 minute later. I look down at my Oil Pressure gauge. Hmmm the needle is farther and I'm not flooring it or even pushing it. It quickly climbed to 120+psi and it is there every time you start it up. What is going on here? Is it the gauge or is it the motor? I smell a oil when I rev, but there is no leakage anywhere...what do I do?

Time to change the oil pressure sender.

X2 that'll be your problem

Ok so does anybody have a pic of what I need and can/should I drive the car while I wait for the part? Are there other parts that will need to be replaced as I replace this one?

Here'* the location. https://www.gmforum.com/trouble-shooting-test-procedures-141/oil-pressure-sensor-location-284737/ Your car will be fine to drive. You only need a new sensor. Remove the old one, a little oil will come out, then put in the new one and plug it in. Done.

Sweet, thanks for th help and info.

There is a special socket made for the oil pressure senders. I don't know if you can rent one from trhe part stores, but you can buy one for around ten bucks

if not a box wrench will work, or a deep socket will work too

This may be the specialty socket:

Special tools are always great to have. However, if your only going to do this one time, then use a box wrench. Might be a little extra effort, but will save some money. Me on the other hand, I buy what ever special tool is needed because I seem to do things more then one time.
