Got back from japfest this weekend and noticed a vibration noise from turbo.
Checked for play on the turbo shaft and had a bore scope in to look for any grinding on housing or damaged blades but absolutely fine.
When I hold/ put pressure on the actuator at turbo end the noise stops. A friend who's a mechanic said it the waste gate seen as we managed to use the scope to confirm that the noise was still there when blades were not spinning. You can also hear the noise when on idle
He used a vac tool and when wastegate is closed the noise stops so we reckon when it's open it just vibrating slightly.
The noise seems to be getting worse though, so any ideas help would be much appreciated.
Cheers
