2SET Compatible with Land Rover Defender TD5 Discovery 2 TD5 1999-2006 Fuel Injector Seal Kit ERR6417 ERR7004 20PCS Copper Washer O-Ring Set

This 20-piece Fuel Injector Seal Kit is a direct replacement part designed to restore the sealing integrity of the TD5 diesel engine. Compatible with Land Rover Defender (1999-2006) and Discovery 2 (1998-2004) equipped with the 2.5L TD5 powerplant. Over time, the original copper washers (ERR6417) can deform and the rubber O-rings (ERR7004) can harden, leading to combustion gas leakage into the fuel system or diesel fuel contamination of the engine oil. This kit contains 10 high-grade copper sealing washers and 10 durable rubber O-rings—everything required to reseal a complete set of injectors during a service or head gasket replacement. Restore your Land Rover's smooth idle and prevent costly oil dilution with this essential maintenance kit.

• Compatible with Land Rover Discovery 2 TD5 (1998-2004) and Land Rover Defender TD5 (1999-2006). Engine Note: Specifically designed for the 2.5L TD5 Diesel Engine ONLY. Please verify your vehicle model and year before purchase.
• This 20-piece kit replaces OEM part numbers ERR6417 (Copper Sealing Washer) and ERR7004 (Rubber O-Ring). Includes 10 Copper Washers and 10 O-Rings, providing a complete seal solution for a full set of injectors.
• Effectively seals the injector port to fix common TD5 symptoms: diesel smell in the oil (fuel dilution), rough idle, hard starting, and loss of power. A must-have replacement whenever injectors are removed or serviced.
• ERR6417 Copper Washers are annealed to provide a tight, high-temperature seal against combustion gases. ERR7004 O-Rings are made of durable, oil-resistant rubber to prevent external fuel and oil leaks.
• For best results, ensure the injector bore and seat are thoroughly cleaned before installation. Lightly lubricate the new O-Ring with clean engine oil. Professional installation and proper torque specifications are highly recommended.
