2.5 CRD injector settings

My 2.5 CRD 2003 has a blowing injector, does anyone have the torque and angle settings for this and any other useful info for someone who hasn't changed the seal before.

All the bolt torque settings are in the Factory Service Manual. You can view and / or download any of the FSM manuals from this online location:
LINK:>Index of /manuals/Jeep/KJ

The injector seal is a copper "crush" washer that fits between the injector tip and the cylinder head. There is also a rubber "O" ring on the injector, but its purpose is to keep any trash out of the injector pocket.
See Picture 1
If the metal sealing surface on the head needs to be resurfaced, there are small face boring bits available online for cheap to perform this with. Just don't get to carried away cutting the metal when resurfacing.
Shown in Picture 1
You can find them online if you search for:> "diesel injector seat cutter" :google:

Looks like the torque settings for the injector hold down bolts on the 2.5 engine are the same as the 2.8 engine.
See section 14, page 3 in the 2.5 FSM. See Picture 2
There is no information in the FSM on injector angles??? Not sure what you are searching for on that subject?

Hi thanks for your message, very useful. I ment degrees, heard that some people add an extra 90 after the torque but I won’t be doing that

NO! Don't be adding any extra degrees after tightening to the specified torque value, it will strip the threads right out. :grim:

A big no-no!

In the diagram a orange o ring is shown situated halfway ish down the injector shaft but I can’t seem to find the correct one available and the jeep dealer suggests that it may not have them on the 2.5 as they can’t seem to find any info/part number. Is this just a feature on the 2.8?
