v6 tdi leaky injector

[swarcup]

ive been smelling a whiff of derv around the car for a few days now and after having a look its pretty obvious that diesel is leaking from the injectors where the injector enters the head.One is deffinately worse than the rest, five of them are just damp but one is weeping. is it that there is a seal around them that needs replacing, if so do i just remove each injector and fit new seal then replace. Anything i should know about doing the job?

Thanks in advance

the engine is a 2.5 tdi qs 180 (ake)

I had a similar problem but it wasn't the injectors, it was the rubber overflow pipes that run between the injectors and eventually return the fuel flow that had perished and were leaking

thank for the heads up are these easy to replace or is it difficult, can you recall the cost?
