Oil pressure sending unit?? My oil pressure gauge has been reading high lately, almost 80 psi at cold startup and stays up there till the engine warms up to operating temp where it goes to about 50. I made a thread about this a couple weeks ago and came to the conclusion that I didn't have anything to worry about, but now I'm convinced that something is up. Leaving the store today I started it up, car still warm, and the oil pressure gauge pegged itself all the way to the right. Shut the car off the the needle went to 20 psi, which is also odd. Started it up again and went to 70 psi. Car still drives exactly like it did before this happened. Am I right in thinking its the sending unit, and how hard is it to change it out? Thanks
The sending unit is right behind the intake manifold, next to the cam sensor. I would swap it out oil pressure is important.

It stays around 20 when the car is off, but as soon as I turn the key forward to turn on the electronics it goes down to 0. I am at a loss as to what to try to fix this.

The gauge started reading higher like this right after the last oil change, so that is definitely possible. I usually use the mobil 1 filter but I am using a K&N this time, maybe its defective. I am going to start with changing out the filter first and see if that solves it.
