hi everyone. i just had new cams and a re shim done on my r. went to collect the car and all seemed ok. no tapping. got 10 mins up the road and it sounded like the fan belt was squeeling. so i carried on driving home. this noise got louder and more persistant . when i got back i opened the bonnet and the noise was coming from inside rocker cover. anyone any ideas. ?:doh:
