Thanks dazza, luckily I have all the tools necessary for thr replacement and I have a BWA engine it that makes my life any easier?. I have a very light rattle so will check this out for sure.
I had a nightmare with my OEM ugly box replacement as something fell down the turbo inlet and I had no idea what it was

all I know is I was removing the silicon hose and something fell in!!! spent 30mintues with a torch and a hose clamp bent in the shape of a claw bit couldn't pick up what it was a looked black like rubber!!! luckily I had a pack of gum in my pocket so chewed three pieces and stuck it to the claw I made. OMGOSH

I found a 25cm squared piece of bonnet trim stuck to the home made claw like wt*

don't know how it dropped off... thay would have screwed my turbo for sure...
