Crap and if it happened after washing the engine the first place I would have looked would have been a coil pack if they have them on the C220 of that vinatage! They get wet and cause a mis-fire! Somehow I do not think the valve was the issue, but may have just been there. You can very well have one burnt valve and the engine will still run right. A bad coil pack causing a severe miss though is much more noticeable. And 3200 bucks to pull a head and put one valve in! Wow the good old MB shops are raping the **** out of you for that. Just my opinion!
