Imjector problem
I had a problem with my W205 220cdi 2 injectors were leaking and there was a build up of carbon which was bad, I replaced the rocker cover cleaned all injectors and the shafts. Put 4 new merc seals and bolts and was fine for a month or two. one injector started leaking again so I took it out cleaned it up. Brought another seal and stretch bolt from merc dealer fitted the injector and was fine for a month or so and started leaking again. Can anyone assist me with an answer ?
Thanks in advance Paul
