I posted this on another site... but I'll post it here too.
Looking for any ideas:

Ok, so here's the story:

As I was getting to work today I noticed that the oil pressure was kinda on the low side.
Checked the oil and she was down about a quart.
Right before I drove home today I added a quart of oil.
Oil was then at the normal level.
On starting the car oil pressure was great. Had around 65psi at idle.
But driving home I noticed the pressure dropped as the motor warmed up... which is normal, only the pressure seemed to drop more than normal. Before long I only had around 25psi... even at 4k.
If I let the rev's drop below 2k the pressure would really start to drop down towards 10psi!
So basically I kept the revs up over 2k the whole way home... which required a little heal and toe at traffic lights...lol
Anyway, so I manage to limp her home... only a few times did I let the pressure get below 2k... only for a second or two.
So after limping her home my 50 mile drive I parked her... well shut her down as I rolled into my parking spot.

So what the fuck happened?
I checked the oil level andit was fine... no sign of leak... no smoke... engine temp was normal.

It seems that once the motor warms up I get a drastic drop in oil pressure... any ideas?

I'm thinking either my rod bearings took a leave of absence... but that's not likelly given the fact that the car still drove fine and didnt knock like a bitch. Or there must be something fucked up in the oil pump/ pressure regulator department.

I'll tow her down to my buddys garage and see what I can find out tomorrow. Just looking for any ideas.

You may ask why did I keep driving at that point... well I figured something was fucked, and any damage would have already been done. So I figured oh well.... lol

Any ideas?

Turns out it was the wiring for my cheap electronic oil pressure guage... go figure!

Life is good again.

whew, you put way too much time into that just to fuck it up. good to hear it was the wiring. which gauge was it so we know not to buy it
