C43/CLK55 Conversion

[Pagz]

Hit the nail on the head there, I think it looks minor too!!... but they are not leaking equally...seriously though I dont know if I can stop myself from replacing them haha(especially since the engine is out of the car)

I read very little about valve seal jobs on the M112/M113 , rings seem to be another story,imo I think dino juice and extended intervals kill them quickly.

The C43 blows a small amount of blue on startup ,there is evidence of oil on the lower threads of half the spark plugs, I will have the engine out for a look this week seals could be leaky and/or ring wear getting up there. ICM shows some monkey ran it for 30,000km's and then topped it up 3.5L. I use to get similar oil on the spark plugs of the c230 turbo..about 2 threads up when the rings would not bed in. anything below that burns off.

No surprise the spark plugs on the CLk55 had no oil on the threads, the engine has been really well maintained.
