    Default Strange noise???

    I have a 2003 2.2dti vectra sri and over the past couple of days i've noticed when i'm accelarating between 2-3000 revs i can hear a quite loud hissing noise,i cant see where it is coming from,i dont have any fault codes or warning lights,no excessive black smoke and if anything its improved my accelaration quite a bit

    Has anyone else came across this, i love the boost in accelaration and dont mind the hissing but i'm afraid if i dont get it fixed it might break something

    Well this has gone downhill rapidly,the hissing is now alot louder from 2000-4000rpm,losing alot of power but i cant find where its coming from,I have checked the intercooler as ive read sometimes that can split etc but its like brand new.

    The car still has no warning lights,black smoke,etc just a loud hissing and poor accelaration.

    Does anyone have any idea's which pipes are most likely to have gone, and hopefully a rough location of the boost pipes as ive been told to check them.

    Thanks

    Check the boost pipes from the turbo through to the inlet manifold/TB.
    Now I need a turbo to keep up!

    Spot on m8 - top hose from turbo has a 2 inch split in it

    Ordered a new one today from stealers but £52 for a small hose like that is just daylight robbery
