Frequently asked questions

What is the 2.6L valve seat insert and what does it do?

The 2.6L valve seat insert is a hardened ring pressed into the cylinder head of the 2.6-litre six-cylinder petrol engine fitted to the Land Rover Series 2 and 3. It gives the valve a durable seating surface and keeps a gas-tight seal in the combustion chamber.

Which engine and models does this valve seat insert fit?

This valve seat insert fits the 2.6-litre six-cylinder petrol engine used in the Land Rover Series 2 and 3 (part 266321). Confirm your engine type before ordering, as the four-cylinder Series engines use different valve seats.

How many valve seat inserts are needed for a cylinder head rebuild?

Typically one valve seat insert is needed per valve, so a full 2.6-litre six-cylinder head usually calls for several to cover all inlet and exhaust valves. Many builders renew all the seats together while the head is off for machining.

Why do valve seats fail, and can this be fitted at home?

Valve seats typically recede or wear after high mileage or on unleaded fuel, causing lost compression and poor running. Fitting isn't a home job; the insert has to be machined and pressed into the cylinder head, so it's normally done by an engine specialist.
