Sorry I didn't explain properly, in the centre of the crank pulley is a large bolt very unlike to have come loose but maybe worth a check.
Thanks for letting me know it's chain driven cam shaft.
Have you had a listen to other identical engines in other identical cars?
Could the noise be a normal noise?
How long have you had car?
How many miles you driven in it?
Has it been serviced properly all is life? Service history?
