hmm a hissing noise you say... you check under the bonnet for a family of snakes living there ???

in all seriousness though i got no clue... however im sure some fine SAU'r will help ya

[eMsta]

is it when u r driving the car or when its stationary?

If its a constant air leak noise, check if its the PCV plug. They are a common thing to break and cheap as chips to replace. It should be a fat hose coming out of the top of your engine near your coil pack cover (left side if ur facing it from the front). Just squeeze hoses until u find it if it happens at idle.

could be a vacuum hose too

[aquariuz6]

Yes it could be one of the vacuum hoses because mine also had a hissing noise but this was due to 2 things.

1. The vacuum hose where its connected to the stock boost gauge had a crack on it.

2. Had a leak on my exhaust. Inbetween the dump and the front pipe.

Gasket had to be replaced.

So yea you should try to find out where its coming from before its too late. I learnt that when i started my car at the shops when all of a sudden the car died after starting it. Vacuum hose just came off and the car was revving up and down on startup until it died.

hey bro it making that noice when i take off in every gear could it be the gaskets or something.

hey,

if your cars feeling laggy.... its deffietly a rooted gasket either between the head and manifold or manifold and turbo.

have fun replacing them... i thought it was my exhaust manifold gasket.. turned out to be the turbo one... but i was gonna replace the exhaust one anyway... snaped 6 of the 12 studs that hold my manifold on... my car hasnt moved for a month

might be a silly post but just want to make sure..

Turbo's make a hissing noise when they build boost.

you know that right?

i know bro but it sounds like leaking air somewhere around the turbo/exhaust area.

[benjo]

so did you find it?

mines doing the same thing. non turbo. just on acceleration, in all gears. ill bet its exhaust tho. this is what ill be check when i get some time. ah , time...
