Land Rover Part Number: ERR1156 - Exhaust Valve - Cylinder Head
ERR1156 is an Exhaust Valve - Cylinder Head. Fitted in the cylinder head of 2.5-litre 200Tdi and 300Tdi diesel engines, this valve controls the release of exhaust gases from the combustion chamber and seals the chamber during the compression and power strokes. It interfaces directly with the valve guides and valve springs; correct seating and timing are critical for combustion efficiency and exhaust flow. Typical applications are Defender, Discovery 1 and Range Rover Classic models - check the valve face condition and seating clearances when fitting as part of a cylinder head service or overhaul.

Frequently Asked Questions
ERR1156 is a replacement exhaust valve for the 2.5-litre 200Tdi and 300Tdi engine families. It opens on the exhaust stroke to allow combustion gases to exit the cylinder and closes to seal the chamber during compression and power strokes. The valve works with the valve guides and valve springs in the cylinder head, so seating condition and timing have a direct effect on engine running quality and emissions.
