this morning, i had to go to a meeting in SF and the car was running fine and all was good.
then, this evening i went to pick up my GF from work and when i started the car, the oil pressure went through the roof. i have the 0-5 gauge and normally the pressure at idle is about ~2 and under full load close to 5. now i'm getting 4-5 at idle and the needle hits the stop under load. (IMG:style_emoticons/default/WTF.gif) i checked on the oil cooler and thermostat, both work fine, supply and return line get hot/warm, so the oil is circulating in the lines. they engine sounds normal and i don't see any oil squirting out of the block anywhere. anyone know what could be wrong?

Just slightly off topic, but what sending unit are you using? I have a 5 bar gauge out of a 911 SC, but am still using the stock 993 sending unit which I understand to be calibrated for 10 bars. So the oil pressure reads double. Basically, the needle is pegged the instant the motor starts, so it acts more like an idiot light than a gauge. Have you fixed this somehow?

(IMG:style_emoticons/default/biggrin.gif) which works very well with the stock 993 sending unit. the 993 sending unit is 5 bar, the earlier 911 sending units are 10 bar. i tried to use a early 911 gauge with the 5 bar range, but it never worked right. so i went and got the 993 gauge ... now i have the correct oiltemp, oilpressure and check engine light all in one gauge. plus, i used some of the other "spare" warning lights to hook up additional "idiot" lights ...
