Land Rover Part Number: LR073779 - Exhaust Valve
LR073779 is an Exhaust Valve fitted in the cylinder head of 2.0 L Ingenium diesel engines. It regulates exhaust gas flow from the combustion chamber by opening on the exhaust stroke to allow combustion gases to exit, then closing to seal the chamber for the next intake and compression cycles. The valve works with the camshaft, valve springs and valve seat to time exhaust release and maintain combustion efficiency; correct seating and clearance are critical. This valve is manufactured for the high-temperature service typical of diesel operation and is matched to the valve seats and guides used on 2.0 L Ingenium cylinder heads. When replacing valve components, confirm the valve type and fitment to the specific engine variant to avoid mismatch with valve guides or cam timing components.

Frequently Asked Questions
The LR073779 exhaust valve controls the release of combustion gases by opening on the exhaust stroke and then closing to re-seal the combustion chamber for the next cycle. It operates with the camshaft, valve springs and seat to ensure correct timing and sealing; poor seating or incorrect clearance can cause loss of compression or valve-to-piston contact. This valve is made for high-temperature diesel service and is matched to the valve seats and guides used on 2.0 L Ingenium cylinder heads, so confirm the correct engine variant when replacing.
