Noticed it over the last two months, its quiet on idle but as soon as i get to 1500rpm it starts knocking (not loudly) revs coincides with speed of knocking but then 1600rpm + it goes quiet and well......... normal. Any ideas anyone? Any help welcome

over tensioned cam belt is a common cause of this.

Might put it through a cambelt and waterpump change with full service and a full flush. Just weird how it only happens at 1500 rpm - no higher and no lower. Not a fan of sportex but it was cheap and cheerfull so ive got a 3" scorpion on route to me
