thanks vodkashots, just what i was thinking, this is the reply i got when i asked how it broke.
i was breaking at the time before a road bump and the car just switched off i tried turning the key but it wouldn't start, i called up AA and was told by them that it was the timing belt after their driver had a look at the engine area, i done some research on the internet and have got to know that mine is not a integrated system so there shouldn't be no internal damage.
i have googled this subject and 99% of the answers i got say it has damaged the valve's
