First off thanks for looking at this thread and for any help or advice given. Also I'm not sure if this is the best place for the thread.

I've got a problem with my fathers Vectra, when its running it produces alot of smoke,white smoke. NOt loosing any water or oil but there is a slight bit of smoke coming from the exhaust manifold.

Is it a matter of just changing the exhaust manifold gasket ???

Any advise welcome !!!

Thanks in advance.
