What a disaster this week has turned into. First off split up with my wife and yesterday my cam belt snapped (waiting for the third). Its being looked at properly on Monday, but the first opinion was that the key has sheared from the back of the bottom pulley. Will wait to see how much damage has been done. What shocked me was the way it happened - not what I expected. Started up fine, drove a couple of mins, stopped at traffic lights and the engine was a bit lumpy on tick over. Pulled away from traffic lights and engine cut out. Trying to start it again just sounded like the starter motor wasn't engaging. No metallic noises at all. Depends what the damage is, but any ideas what this is going to cost? Garage said roughly £800, but hard to estimate yet.
