Does the valves bend when the timing chain slips on sprokets, on a mercedes benz 2008 model C200 komp?

    Don't know the car specifically, but in 90% of cars, if a timing belt or chain slips, the piston bangs into the valve and bends it. Oct 30, 2013 at 10:15

    FYI, what you want to know is if your car has a free-running or interference engine. An interference engine out of time will damage the valve(s) and/or cylinder head(s). Oct 30, 2013 at 15:35
  • As the answers say, yes. Alternatively I've seen pictures of valves having punched a hole in the piston instead. In any case a significant timing error will cause a collision and engine damage. I can't recall if the K engine there is one of the sensitive ones that "stretch" chains or eat their cam sprockets quickly.

I've checked a number of sources and they all state that the engines in these are Interference Engines so there is a good chance of contact between the valves and the piston crowns. A compression test once the timing has been re-set would be a simple way to check if this has happened without taking the engine to pieces.

Yes you can bend valves and mercedes will generally not cover resultant damage even during warranty period.Mercedessource is a good site hosted by a Mercedes technician
