I have recently noticed an increase in the clack clack (for want of a better description ) noise at 3000 - 3500rpm. It has always been there, and a little at around 5000rpm.
Advice from other Seveners, and reading Blat Chat, tell me it's induction knock and 'normal'. This is reassuring but I still have a concern.
Why has the noise at 3000 - 3500 increased in volume recently? Why would it get noisier?
Engine has been raced but had rebuild around 6km ago. IF milage is to be believed it's done 40km. Still drives / goes well.
