Land Rover Part Number: LR029317 - Exhaust Valve - Cylinder Head - Puma Diesel
LR029317 is an exhaust valve for Puma diesel cylinder heads. Fitted to the cylinder head, the valve controls exhaust gas flow from the combustion chamber during the exhaust stroke and provides a gas-tight seal against the valve seat during compression and combustion. In service the valve is exposed to high temperatures and combustion by-products; common reasons for replacement include worn valve seats, pitting or burning of the valve face and excessive stem wear that causes poor sealing or valve guide play. When replacing this valve ensure it matches the cylinder head specifications and that valve clearances are set according to the engine's service procedures.
