Burnt Valves


Ford Doctor

A misfire and low compression led to discovering this burnt exhaust valve. Burnt valves can have several causes that lead to a poor seal between the valve face and the valve seat. These causes include cylinder overheating, defects in the valve and or seat, fuel injection concerns and even EGR problems that fail to control combustion temperatures. A look at the burnt up tip of the glow plug indicates that temperatures in this cylinder were pretty high.
