Frequently asked questions

What does the ERR7004 injector O-ring seal on a Td5 engine?
The ERR7004 is a Genuine Land Rover O-ring that seals the fuel injectors into the cylinder head on the 2.5L Td5 five-cylinder diesel. It prevents fuel and combustion gases leaking around the injector body. It fits the Td5 Defender (up to 2006) and Discovery 2 (1998-2004).
Can the Td5 injector O-rings be reused when servicing the injectors?
No. Injector O-rings are single-use components. Once compressed and heat-set, they won't reseal correctly and risk fuel leaks or compression loss if reused. Replace all five O-rings whenever injectors are removed, even if they look undamaged.
Why use the Genuine Land Rover O-ring rather than an aftermarket equivalent?
The Td5 injector bore is a high-temperature, high-pressure environment. Genuine O-rings (ERR7004LR) are made to the correct specification for the injector diameter and fuel-resistant compound, reducing the risk of fuel leaks and injector seating problems.
