my middle box was cracked so i've had a new one fitted today but there is quite a bad blowing noise coming from somewhere in the front and it only does it sometimes. It sounds like the manifold that is blowing when i open the bonnet but it also does it under the car..... It will only do it when the engine is hot aswell, so i cant get my hand anywhere near the manifold to see if it is that that is blowing!!! any help lads?!?
probably the join from downpipe to system, get a new o-ring seal for it, bout a fiver and just two bolts holding it on, as for checking the manifold when hot, hold a bit of paper near it and see if it gets blown about
