Hi there,
A couple of months ago, June or July, i had new injectors fitted to my TD4, with new seals.
Recently i had a new Turbo fitted and had an issue with the boost sensor. While trying to resolve this I found that cylinders 3 and 4, (assuming cylinder 1 is the closest to the transmission), are leaking diesel from around the top of the injector after turning the motor off.

I have not tried to re-torque the injectors yet, will have the Mechanic do so on Thursday when they replace the intercooler.

Has anyone seen this before? I dont want to replace injectors again.

I have a little 2MB video I can share, I tried uploading this but kept getting an error.

Regards Thanks

It can be the leak-off pipes, not the injectors themselves.
The o-ring (used to seal off the connection) ages and start to leak, considering that the pressure in the leak-off pipes is about 10 bars.

Thanks Alex.
I will ask them to check and replace the O-rings.

Regards Thanks

Make sure the leak off pipe is actually clipped onto the injector properly...it needs a firm push with the lock unclipped to get it on properly.

Thanks Mike, I am sure the return pipes are secure but I will ask them to verify this tomorrow when they replace the intercooler.

Regards Thanks
