Hi, pretty sure my cars developed a boost leak as its making a very strange whistling whenever its on boost but nothing at all when off boost. I had a look last night for split hoses but can't find anything at all, but I did notice iv knocked my intercooler pipework and put a large dent in it where it connects to some tubing so I reckon its not flowing right there either.
Where's the best place to get new boost pipes from as am just going to replace the lot as I can't find the leak? Also if anyone has any spare intercooler pipework Il gladly take it off them as I have no idea where I'd find any without buying a whole new kit.
