View Full Version : LMM: turbo noise

07-09-2008, 01:45 PM
I'm having a turbo noise (I think). At first I thought is was the blower motor but it is not. Then I thought it was an air leak. But it wasn't. I unhooked the air tube and it still makes the noise. It sounds like when the vanes cycle but is stays in loud stage. It gets louder with higher rpm. The bearings in the turbo sound ok. Any ideas?
