hey this is my first post. i currently drive a civic with a 1.6 type r engine in it. but am hopefully picking an arden blue gsi up tomorrow. ive been to look at the car and everything seem ok apart from the engine sounded a little bit noisey on tick over with the bonnet open and when i pressed the accelerator one of the pipes seems as if it was collapsing. is this normal? this is my first turbo car and i just want to make sure before i buy it.
