swap your injectors
you might not be able to remove the rail and injectors in one piece
better disconnect rail
gaskets are hard and old
you can buy tested recent second hand injectors and service them with SeaFoam if you have skills
don't forget to replace all 24 top and bottom gaskets if your injectors don't have them, around 85$ at MB
to put the injectors back, put them on the rail, grease them with Vaseline or rubber proof grease, same engine side
the whole rail will swap in under the electrical wires from the driver side
no need to disconnect everything
have fun
originally I replaced all hoses and sensors as they where breaking hard
now that I have been searching for perfection I am looking for 0 ignition faults
last thing to check was this
now I have 0 faults, even with 6000 rpm




I have a slight smooth running fault when cold on 2 cylinders, goes away after 2 minutes. I think its injectors but don't want to pay £800 for injectors, How do you repair the old ones?
get 12 recent and tested injectors from ebay
get seafoam or injector cleaning spray
then do this
this is the CL65 injector A2750780349
this is the CL600 2750780249 injector
I couldn't upgrade to those as it would cause a calibration problem
the whole ecu-tune would need to be redone

The Best of Mercedes & AMG
best is to blow the whole top engine
then, before removing injectors, disconnect them from the rail by moving the clips back
then W40 around the injectors
blow air again
and always close the turbo inlets with a tissue once you remove the air flltes !
if a screw falls in there, you still have a change with a magnet
