Found out what happened to me 172. Alternator came loose, belt sheared and got caught in the cam belt, cam belt slipped and bent all of my 16 valves!!
What a pain in the ass., If it wasnt for the warranty, this would be costing me £3500 just for the damned engine to be bought, not labour!!!!
Get it back on Friday though hopefully!! Gotta run the thing in again though!!!
