Oil Pressure Question/Problem
I've had my STi for 4 weeks now. It has a turboback, short ram, and blitz sbc-id BC.....all of which I bought with the car as it was used. My oil pressure was fine up until this past weekend. I was running about 1.6bar at idle and 6bar when driving. Well I went on a 200 mile trip on Sunday and when i got there the warning buzzer was going off (1.4 bar) at idle and it was running about 5.5bar at speed. I checked the oil and it was a little low. So I added a quart. That didnt seem to help. Well I completely changed the oil on Monday. 5 quarts of Mobil 1 synthetic hoping to fix the problem. But now I'm running about 1.2 bar at idle and 5bar at speed. I have no idea what's going on.
