Injector Sealing Washer seals each fuel injector into the cylinder head within the diesel fuel injection system, for 200 TDi and 300 TDi turbo-diesel engines.

This washer seats at the base of the injector where it enters the cylinder head, forming a combustion-gas seal around the injector bore and preventing blow-by past the injector seat. Renewed whenever an injector is removed.

Frequently asked questions

What does the injector sealing washer do?
The injector sealing washer seals each fuel injector into the cylinder head on 200 TDi and 300 TDi diesel engines. It forms a combustion-gas seal around the injector bore and stops blow-by past the injector seat.
Can the injector sealing washer be reused?
No, replace the injector sealing washer every time an injector is removed. These washers are typically single-use, and a reused washer can fail to seal and let combustion gases blow past the injector.
How many injector sealing washers are needed?
Typically one per injector, so four for a four-cylinder 200 TDi or 300 TDi engine. Renew the full set whenever the injectors are disturbed rather than reusing any of the old washers.
Which engines use this injector sealing washer?
It fits the 2.5L 200 TDi and 300 TDi diesel engines in the Defender (1987-2006) and Discovery 1, and is also listed for the Freelander 1 diesel.
