I have noticed that my injector seems to be moist on the top. The metal tube?

Sorry to bring up and old thread but i have the exact same problem with my dse. What pipes did you replace? cheers.

Just bought a 1998 2.5 dse. Injector 1 is leaking. There is a little puddle of diesel that collects around it and when runnin you can see air bubbles escaping through it. Just wondered are the injectors easy enough to swap over and is there anything i need to remember to do when changing them...
