We have a 2008 2 litre Megane and a newly fitted cam belt has jumped a few cogs causing internal destruction. Has anyone had a similar experience with valves hitting pistons, as tends to occur with interference engines when this happens? Is it usually terminal for the engine or is there still hope? I realize that the head will have to come off to see the extent of the damage and valves will probably be bent. The engine did still turn over after the episode but she would not start. There did not seem to be any mechanical interference. If it is terminal for that engine we may have access to an engine from a similar Megane but it is an auto. Is the crankshaft the same for the manual and the auto?
