Tapping/rattling noise from the engine
Hi I have just purchases a 1.2 Clio 8v and after the car is warm and ticking over every 30-60 seconds there is a loudish rattling/tapping noise that lasts about 10 sec then goes again anyone any idea what this could be

also when the car is in motion it does not make the noise


many thanks
