ford focus diesel injector leak - dipsomaniac
diesel is spraying from the top of one of the injectors on 1999 ford focus 1.8 diesel. i have noticed that the orange 'o' ring on this injector appears to be missing. it is visible on the other three. i have tried tightening the injector.

does anyone know if i can just buy just the 'o' ring and is it difficult to change? any advice appreciated.

It is a copper "o" ring that fits to the return i think that is what most car's have so if so yes they cost peanuts. good luck..

thanks bigtee. i have never worked on a diesel before. is the system pressurized? can i just unscrew the injector and fit a new o ring?
