Frequently asked questions

What is the ERR3343 rocker arm used for?

The ERR3343 is the right-hand inlet valve rocker arm for the Land Rover 2.5L 300 TDi turbo-diesel engine. Sat on the rocker shaft, it passes pushrod movement from the camshaft to open the inlet valve, letting air into the cylinder on the intake stroke.

Which models use this 300 TDi inlet rocker?

This 300 TDi inlet rocker fits Land Rover vehicles with the 2.5L 300 TDi engine: the Defender, Discovery 1 (VIN FA393361 to WA799999) and Range Rover Classic (1992-1994, from JA610294). It's the inlet rocker, so it pairs with the matching exhaust rocker on each cylinder.

What are the signs a 300 TDi inlet rocker needs replacing?

A worn 300 TDi inlet rocker typically shows as a tapping or ticking noise from the top of the engine, often with valve clearances that won't hold their setting. Wear usually appears at the valve pad and shaft bore. Rockers are commonly renewed as a set when the shaft is off.

Is this the inlet or exhaust rocker, and is it handed?

This is the right-hand inlet rocker. On the 300 TDi, inlet and exhaust rockers sit alternately along the rocker shaft, so it's worth checking the casting against your old part. When rebuilding the cylinder head, mechanics typically replace inlet and exhaust rockers together across the set.
