Consumer Description

We were driving and noticed some white smoke when we parked, so we took it to a mechanic and he diagnosed: “Found that only when engine gets up to operating temp that it begins to leak through hairline cracks in cylinder head. Oil leak is severe and recommend not driving and bringing to dealer for possible warranty verification.” He told us the issue is specifically on the driver side where there are hairline cracks on the backside, left quarter of the cylinder head.
