Leaking prechambers OM603
Hi, I have a `91 300 TD Turbo(Euro/Norwegian).
I ofcoarse have trouble with leaks around the prechambers, some small leaks at cyl 3 and 4, but after I checked my nozzles, I`ve got a decent leak at cylinder 1, It`s squirting diesel out of the half-moon next to the prechamber-locking-nut, and the engine runs om 5 cylinders at idle.
I have ofcoarse checked the nozzle/injector, changed the injector seal ring. But Cant find anything.
I have bought a socket with the correct splines(KLANN KL-0369-3), and will try to pull them out tomorrow, but I dont have the grinding tool, or shims, I`m going to make a tool for pulling out the prechamber from a used nozzle.
Do you have any tips forr me, what I should do, how?
I`m thinking about using a thin copper or aluminium washer for the seal if I need to, and maybe take a little cut in the prechambers to keep correct position of them.
Do you have anything for me, experinces, other stuff.
Thanks from Norway...
