    My oil keeps getting used up quickly but I can't find a leak anywhere nor can the garage. They changed my rocker gasket but still the same problem. Also the water seems to boil when I'm stuck in traffic could this mean there's a head gasket failure. Thinking of taking it to a vauxhall garage I...
