Rare CLK63 Vert in for maintenance. Vehicle has a slight misfire. Prev. Owner replaced 1 ignition coil and all spark plugs with no change. Removed and replaced all 8 injectors, found 1 to be bad, and another right behind it on its way out. The rest were dirty and nearing the end of their life. Oil leak was from a failed pcv pushing oil out of the back onto the elbow for the intake which would then drip over onto the exhaust and transmission.

Replaced PCV, Coils, Injectors, and Valve cover gaskets. DIY for all m156.
