This inlet valve guide is a precision-fit component for the cylinder head of Land Rover's 2.5-litre diesel engines, controlling the lateral movement of the inlet valve stem to maintain accurate seating and combustion chamber sealing. Worn valve guides allow oil to be drawn into the combustion chamber, resulting in blue smoke from the exhaust, increased oil consumption, and poor combustion efficiency. Replacing guides to the correct specification is essential when reconditioning the cylinder head to restore proper valve operation. Key Features Inlet valve guide designed specifically for the 2.5-litre diesel cylinder head assembly Requires pressing into the cylinder head - professional fitting and reaming to size is recommended after installation Compatible with both naturally aspirated and turbocharged variants of the 2.5-litre diesel engine Cylinder heads typically carry multiple inlet valves - confirm the quantity required before ordering; valve stem seals should be replaced at the same time Vehicle Fitment Fits Land Rover Defender (1986–2006) equipped with the 2.5-litre Naturally Aspirated Diesel and 2.5-litre Turbo Diesel engines.
