Inlet Valve for the cylinder head valvetrain of the 3.5 V8 carburettor petrol engine.

The inlet valve seals the intake port against combustion pressure and opens to admit the air/fuel charge as the camshaft lobe acts through the pushrod, rocker and valve stem. It runs in a pressed-in valve guide and seats against the machined insert in the cylinder head; the stem carries the valve spring, collets and stem oil seal.

Inlet valves are normally renewed as a set when a head is reconditioned. Each valve must be lapped to its seat on fitting and stem-to-guide clearance checked, so that compression sealing and valve cooling through the seat face are restored.

Frequently asked questions

What is the Inlet Valve – 3.5 V8 Carburettor used for?
The inlet valve seals the intake port of the 3.5 V8 carburettor cylinder head and opens to admit the air and fuel charge as the camshaft acts through the pushrod and rocker. It runs in a pressed-in valve guide and seats against a machined insert in the head.
How many inlet valves are needed for this engine?
The 3.5 V8 uses one inlet valve per cylinder, and they are typically renewed as a set during a cylinder head overhaul rather than singly. Check how many your job needs against the heads being worked on.
Which vehicles and engines use this inlet valve?
This inlet valve fits the 3.5 V8 twin-carburettor petrol engine in the Defender 90/110 (1987-2006, up to VIN LA921745), the Series III 109 inch Stage One, the Range Rover Classic carburettor V8, and the Discovery 1 V8.
Why do inlet valves need replacing?
Inlet valves need replacing when they burn, wear on the seat or stem, or stop sealing, which shows as lost compression and poor running. They are usually renewed during a head rebuild while the head is off.
