description

The cylinder head assembly is the core upper component of diesel engine, integrated with valves, valve springs, valve seats and guides. It seals the top of cylinder to form combustion chamber, arranges intake ducts, exhaust ducts, cooling water passages and lubricating oil passages, and cooperates with injectors to realize combustion and power output. Warped deck surface, poor valve sealing, casting porosity and water jacket cracks will lead to blown head gasket, mixing of oil and coolant, air leakage, low cylinder pressure, abnormal exhaust and power loss. In severe cases, coolant entering cylinder may cause catastrophic engine damage.

FAQ 

Q: Can a slightly distorted cylinder head be reused after deck resurfacing?
A: Machining repair is acceptable within OEM allowable material removal limit. Replace assembly if removal exceeds limit or hidden cracks exist.

Q: Why is it recommended to replace cylinder head bolts together with the new cylinder head?
A: Cylinder head bolts are torque-to-yield fasteners. Metal fatigue occurs after stretching, and reuse may result in bolt breakage and blown gasket.
