Sticking Valves

This valve was extracted from the cylinder head of a 7.3L Power Stroke Diesel engine. The engine had apparently not been started for some time and rust had formed in the valve guide leading to it's sticking. Above the valve is the mating push rod that was not only bent but it shattered. This is due to the piston striking the valve. This phenomenon also affects 6.0L engines as well. Not very common.
