how to remove injectors from om606 engine
is there any guide with images or video that shows how to safely remove them ,
the reason why im doing this is that on idle the engine makes a knoking noise until it reaches the 85C degrees temperature than the knocking noise nearly dissapear . if the injector are fine (something that i really doubt) than i gues i should have to check the hydraulic valves or lifters if they are wear to change them all .
a mechanic advised me to add a small amount of oil to the fuel but the noise wont stop.
today after i started in the morning i noticed at the exhaust pipe creating water in the ground

the car have 202k km and are the original injectors ,maybe the nozzles need to be replaced after removing the injectors i think i will remove the glow plugs too to see if they need to be cleaned or replaced and clean the glow plug inner hole too from carbon, etc,
i love this car and i like to take care of it , before doing something wrong i thought it might be better to ask on the forum and have some opinions from the other users .
here where i live the are noo good mechanics so i think t do it by my self
