Which oil pressure sensor?

I'll more than likely damage the sensor, but once I replace it w/ a one I'll try to repair the old one, that way I'll have a spare. You should have a free lifetime membership for the amount of useful information you but in here.

Well as the write-up says, I really didn't set out to fix the old one. It's the engineering background I have that made me curious about the failure/leakage. Then when I discovered how easy it was to fix ..... one thing lead to another and I just had to know if the fix worked

Don't fret over this part. It's used on lots of other GM cars. I accidentally broke mine the other day while changing my serpentine belt and discovered that my local Advance Auto Parts store (and also AutoZone) had these senders in stock for a bit over $25. I bought one, put it in, and all is fine again.

Yep, I agree. One of those things that doesn't warrant too much over-thinking

Installed the new sensor yesterday. Worked like a charm. I'll have to see what the normal operating range is. It's in the 70 range to start, but then backs off after a few minutes.

Typically the pressure will be higher when the oil is cold, in any motor.

I've found that aftermarket senders may not jive 100% with the calibration of OEM senders, but since we're talking about relatively inaccurate OEM gauges here, it's really not a significant difference. The main thing is to know what's "normal" for that particular sender.

Makes sense, thanks. I'm not gonna worry about then, unless it pegs or barely goes past 0. It's just nice to see that it's not fluttering around anymore. Was always catching my eye.
