Broken exhaust valves - IS200

I have an IS200 which recently came from the workshop after getting some bodywork and the differential repaired. On my way home the engine lost power only to later find out that all exhaust valves were broken. However, no inlet valves were damaged. The timing belt and all pulleys and tentioners are in good condition. Does anyone know what could have caused this to happen?

Hello, I have the same problem, but the car is running on LPG, will open the cylinder head, and see why the idle is bad, like if it is running on 4 or 3 at cold start.
