Finally got a chance to do some diagnostics. I removed the aux belt Idler and the cam belt cover. Everything looked OK, the belt is over 3 years old but I've only done about 8k miles in that time so the condition was nearly new.
Cut the balance belt off. ...........and the nose has gone!
I've had this before and believe me, the noise is a very loud knock. So the question is, what is causing my balance belt tensioner to fail?
The clutch release bearing is singing and there is also a sound like air escaping at pressure, quite high pitch and disappeared one the engine was warm.
Still, nothing serious so on with the cam belt change next! !
