Usually with main bearing problems, when you throttle it up fast, your oil pressure will drop instead of increase. Try this and post the results.

Nope, sitting still you can throttle up to 2k with no undue noise. The oil pressure is ok, the only time I ever see it drop is if the level has gotten a bit low, then coming to a quick stop the pressure will drop a bit as the oil sloshes around.

Rev: I've thought about the sensor, but wouldnt the car show a code on startup if it went bad?

Thanks for the help so far folks,
