Fuel leak viano 3.0cdi please advise.

[Iskapsts]

Hi Folks,any advise on this nasty fuel leak.
Injector or return line maybe,cars ride/performance is not affected which Leans me to think a return line,that is very hard accessible furthest injector I think nr:6.
Didn’t see any specific leak on idle,but during drive it really leaks and with wind I guess it has taken it up till rear axle even in front wheel arch.
Any advise please.

many thanks.

Looks like either high pressure connection is leaking (rare, if proper tight) OR your injector nozzle holder is cracked and leaking in foot of the injector and it soaks injector top parts...

Is there something broken as in picture,i cannot see it normally as only access is to push phone deep in to get this picture.

could it be injector nozzle holder as as you said,but again would cracked holder plastic generate any leak?

That is just electrical connector, nothing near to pressurized fuel. Yes, very rarely top of the injector can seep the leak fron the bottom of the injector but even then leak usually comes from thread of the solenoid/piezo part.

Many thanks for your help mersum1es,
After extensive filming at engine idle found leaking injector two injectors up from suspected I think it’s nr3 the one closer to radiator,I will upload link to video shortly,we’re bubbling from injector housing can be seen,I gues it’s the copper seal or just bolt not tighten enough’will keep updated
Regards

If you get pure fuel from bottom it is most likely cracked nozzle holder. Copper seal failure alone push some black tar from cylinder, combustion still works at least partially.

Trough the upload quality has dropped but still bubbling can be seen,also was filming this blind as per resonator position there is no really much access for camera and torch.
Because of the engine tilt backwards leaking injector housing seems not flooded unlike further two injector housings above in post

this leaking injector has been replaced in july 2018,still have invoice and receipts from previous owner.
its hard to spot from upload,but on original video when zoomed i can see some black tar at bottom so to say very early stage of black death.
