with both previous responses. Look at the stickey titled Oil Pressure Sender Relocate. It's got info about the sender failing and the various ways to replace because it is a little less that straight forward to access the sender for service.

High Oil Pressure - Help Needed
Driving into work today I noticed that my '98 coupe's oil pressure gauge was buried to the right at 80 psi. I scrolled through the DIC and saw that the pressure was 128 psi. For the remainder of my 15 mile drive, the pressure remained between 126 psi and 130 psi.
This can't really be a normal operating condition, can it? Isn't normal psi around 40 psi (making my car's pressure nearly three times normal!)?
I need to drive home today after work. Am I risking damage to the engine? What might be causing the issue?

Many of us just replace it... If done correctly there are no issues.

They're now making brass Chevy sensors that have the correct metric threads. The Buick sensor has NPT threads, and requires a threaded adapter for use.
BWD S4202 from Advance Auto Parts, and also other Parts America stores, is a direct fit brass sensor.

I just wanted to say thanks to all of you who replied.
What a PITA this is going to be! I spent a few hours both yesterday and today researching this issue and reading all of the threads here. I am not looking forward to this project, and I'm not yet sure what way I'll go with the repair (cut the hole, relocate with hose, or move to front of block). Each option seems to have its pros and cons.
As a car guy I'm not really ok with the idea of driving my car with no oil pressure reading. That said, I really would prefer to not be without my car right now (it is my daily driver). How long do you figure I'll have before the sensor starts leaking oil (or will it at all)?
Thanks again,

I went with the chop a hole method. I thought about it cause I didn't want to cut a hole in the car. But I did and it's simple. Can't see it. Doesn't bother me now. 30 minute job or less depending on how hard the wipers want to be in removing themselves.

The manifold removal isn't that bad but if you cut a hole, just make a NEAT plate to cover the hole and rivet it on then you'll have good access for the future. There are a couple of other things back there that having access to are NICE (like the vacuum supply for inside the car).

If space allows it, I'm thinking about installing a small 0-100 psi guage
in the front oil pressure tapping on the engine.
I've decided to leave the sensor in the stock location, hoping the new brass sensor will prove to be a more durable replacement.
