Injector O-Ring and Washer Kit - the sealing set for the fuel injectors of the Td5 2.5L 5-cylinder turbo diesel engine.

Each injector seals at two points in the cylinder head: a copper washer at the injector tip, which seals the combustion chamber, and an O-ring on the injector body, which seals the injector bore. Both seals are single-use and are renewed whenever an injector is removed - deteriorated seals are a common cause of combustion leakage past the injector and of poor starting and running.

The kit contains five copper sealing washers and five O-rings, one of each per injector.

Frequently asked questions

What does this O-Ring and Washer Kit seal on the Td5 injectors?
This kit provides the sealing washers and O-rings for the fuel injectors on the Td5 2.5 litre five-cylinder turbo diesel. Each injector seals at two points: a copper washer at the tip that seals the combustion chamber, and an O-ring on the body that seals the injector bore.
How many washers and O-rings come in the kit?
The kit contains five copper washers and five O-rings, one set per injector, covering a complete Td5 engine in one kit. You won't need multiples unless resealing more than one engine.
Why do injector seals need replacing on a Td5?
The copper washer and O-ring harden and lose their seal over time from heat cycling and diesel exposure. Once they deteriorate, combustion gases can leak past the injector tip, typically causing poor starting, rough running or a diesel smell around the injectors.
Which vehicles does this injector seal kit fit?
This kit fits the Td5 2.5 litre engine only, as used in the Defender 1986 to 2006 and Discovery 2 1998 to 2004. It's not compatible with other diesel engines in these ranges, so confirm your engine code before ordering.
Can these injector seals be reused once removed?
No. Both the copper washer and O-ring are single-use seals that should be replaced every time an injector is removed. Reusing a compressed washer or heat-cycled O-ring typically won't reseal properly and risks a combustion leak.
