ERR3342 - 300TDI Rocker Arm - Left Hand - For Defender, Discovery 1 and Range Rover Classic (Part Number: ERR3342)

Left rocker (rocker arm) for engine 300TDI (2.5L) Land Rover Defender, Discovery-1 and Range Rover Classic

Replacing rocker arm ERR3342 is usually needed not by schedule (mileage), but by wear or breakage.

Here are the main signs that the unit needs attention:

• Rattling noise: If you hear a clear metallic rattling in the upper part of the engine (under the valve cover) that does not disappear after adjusting the valve clearances. This often indicates wear on the rocker arm "nose" or bushing wear.
• Unable to adjust valves: If when trying to set the clearance you see that the rocker arm tip has a strong play or uneven surface at the contact point with the valve.
• Power loss and smoke: Due to wear on the rocker arm, the valve may not open fully or with a delay. This disrupts gas exchange, the engine "stutters" and may start smoking.
• Visual defects (with the cover removed):Wear (indentation): A depression appears on the working surface pressing on the valve.
• Cracks: On the body of the rocker arm itself (especially relevant for old 300Tdi engines under high loads).
• Play on the axis: If the rocker arm "wobbles" sideways more than normal - the bronze bushing inside has worn out.

Advice: Since 300Tdi engines are very reliable, rocker arms often last for 200-300 thousand km. However, if you remove the valve cover for adjustment (which should be done every 20-30 thousand km), be sure to check them for play.
