Injector torque

[Vince88]

Hi,

Last year I had endless issues with my t180 and eventually resolved with new injector as one was cracked.

One year and approx. 5000 miles later there has been bad smell in the car. Inspecting the engine there was some sludge around one injector and it was blowing. I checked the clamp bolt and noticed it was loose.

I tightened in to about 25Nm and it improved it but still blowing slightly.

So, I intend to return the car to place I had work done as I suspect they did not torque them properly.

I would like to know -

1) what is the correct torque dcat 2.2 diesel engine 

2) should the seals and bolt be renewed?
