View Full Version : Low Oil Pressure?

01-16-2010, 05:48 PM
I have a 2006 WRX with 77k miles on it and a bunch of mods (bigger turbo, exhaust, larger front mount intercooler, a different transmission and suspension).

My oil gauge alarms under 20 psi, but when I'm idling, which is roughly at 750 rpm, it drops between 20 and below that to alarm.

What could be causing this problem?
