my c20xe keeps blowing rocker gaskets for no reason.
i havent tried a genuine vaux one yet due to the price but have gone through 4 cheaper ones.
any suggestions as to why this is blowing?

because it might have a sharp edge on the rocker cover causing the gasket to split, it happend to me about a week ago. rub the edgeds down so its all smooth & use a gm gasket & it should be job done, hope this hepls you out abit mate.
