May 27, 201114 yr I have an 05 sti and can't figure out what the problem is... won't boost doesn't knock when. Started. Blows oil out of the exhaust clean oil and white smoke. Did compression test and had good compression on all four cylenders. Havent tore anything else down to check but just wanted other opinions. Maybe oil seal in the turbo?
May 27, 201114 yr Blown turbo. It's throwing oil and coolant into the exhaust and explains your lack of boost. GD
May 27, 201114 yr X2 on bad turbo. Pull the intake tube off and I bet you can wobble the compressor wheel around like a joystick.
