View Full Version : BOV problems

05-18-2010, 01:48 AM
I bought a 2000 GTB legacy E-Tune and it came with a BOV.
The BOV is playing up and some days it works fine, but others it just makes a very faint cough sound.

Any ideas what it could be?
Would it damage the engine if i dont get it fixed?

sounds like its not working right, could be a bad bov or u have a vacuum leak some wear. it will hurt the turbo bearings if the pressure is not released.
