Title: hissing from engine
Post by: simonc2829 on 12 July 2015, 15:48:15

Hi all got a strange problem with my 2.2 2001 it has a hissing sound from the engine which is louder when you first start the engine. The last two days the weather's been hot and after driving for about 2 miles the engine stalled then started up straight away it didn't stall again all day. Now the weather's cooler it's not stalling but it's running a little rough any help gratefully recieved

Sounds like a manifold air leak  :y Or a pipe off

Thanks for the reply. It sounds like it's coming from the manifold area hissing still there when warm but not so loud

Be an air leak where two of the breather pipes crossover between the Camcover and the throttle body...

No coolant loss and the dipstick and oil cap are gunge free
