hi i have got a noise like a blowing exhaust (somone blowing a rasberry) the exhaust is fine with no holes. This only seems to blow under driving load. does anybody have any ideas. i think it could be the manifold gasket.
also when the engine warms up its still there.

thanks neil

its most likely to be leaking inside the flexi joint on the front pipe thats why you only get it under load because it opens the joint.

put load on it by trying to gently pull away with the brakes on while some one looks under the car for you.

cheers will check it out tomorrow.

cover end of exhaust with a ball of rag to seal it, if car dont stall there is a leak in exhaust system some where
