Any thoughts and whats the best way to drain a fuel tank in these guys? Link to comment Share on other sites More sharing options...

You have got other issues like idler bearing noise or alternator bearing or even turbo impellor scrapping inside the housing. You could remove the engine belt and start the engine briefly and that would remove the first two variables. If the noise is still there remove the intake pipe off the turbo and ( with the engine not running ) look and feel for any for any scrapping of the impellor in the housing. Even check for loose bolts ect. 1 Link to comment Share on other sites More sharing options...
