Diesel injector bolts
So After 212000 very reliable miles on my 2011 W204 blue efficiency, OM651, I decided that my now lumpy engine (when cold) needed to have the injector nozzles cleaned.
As recommended, I ordered in a set of replacement copper sealing washers and a set of TTY bolts from a German supplier only to find that the bolts that arrived were M6 and my engine uses M7's.
It would appear that M7 TTY injector bolts are a very uncommon after market part. Admittedly, I haven't gone through my local Merc dealership yet.
I can find no reference anywhere to this engines injector bolts being upgraded from M6 to M7.
Can anyone shine some light on this for me please?
