Land Rover Part Number: ERR6612 - Cylinder Head Exhaust Valve - Td5
ERR6612 is a cylinder head exhaust valve for Td5 engines. Fitted to the Td5 2.5L 5-cylinder turbo diesel cylinder head, the valve opens and closes under camshaft actuation to allow timed release of combustion gases; the valve face seals against the exhaust seat and the stem runs within the valve guide to maintain alignment under high temperature and pressure. The component is machined and heat-treated where specified by the engine design; replacement is required where the valve face, stem or seating surface shows wear, burning or distortion that affects sealing or timing, and servicing should include inspection of valve clearances, seating condition and associated springs and collets.
