Frequently asked questions

What is the ERR3342 rocker arm and what does it do?

The ERR3342 is the left-hand exhaust valve rocker arm for the Land Rover 2.5L 300 TDi turbo-diesel engine. Mounted on the rocker shaft, it transfers pushrod motion from the camshaft to open the exhaust valve. It's the exhaust rocker in the rocker shaft set.

Which Land Rovers does this 300 TDi rocker arm fit?

This 300 TDi exhaust rocker fits Land Rover models running the 2.5L 300 TDi engine, including the Defender, Discovery 1 (VIN FA393361 to WA799999) and Range Rover Classic (1992-1994, from JA610294). Confirm your engine is the 300 TDi, as the earlier 200 TDi typically uses different rockers.

Why do 300 TDi rocker arms wear out?

300 TDi rocker arms typically wear at the valve-tip contact pad and the shaft bore, usually from high mileage, infrequent oil changes or oil starvation. Worn rockers often cause tapping noise from the top of the engine and uneven valve clearances. They're commonly replaced as a set.

Is this rocker handed, and how many are on the engine?

This is the left-hand exhaust rocker. The four-cylinder 300 TDi uses separate inlet and exhaust rockers, so a full rocker shaft set holds several arms. If one is worn, mechanics typically inspect the rest of the set, since they share the same shaft and oil feed.
