I agree with you Pete and it's the reason why I need my daily fix of the forum 😊. Always a great read, intresting threads, fantastic rebuilds and a good bit of friendly banter. It's like meeting your mates in a Weatherspoons but without the punch-ups😉!

Where oil comes back down from the head it drops onto the crank more than other extremes of crankcase, so it tries to seperate it to push it down toward the sump usually.  A bit like a potatoe peeler.

I have found that they do nothing at all. I never repair them and have never had a problem. And it is always the same size and shape  ;)

My theory is that Honda put it in the casting so, if your chains go loose then it chips the bit off and you find it in the sump. Just a reminder that your chains and tensioner need replacing  ;)   ;D ;D ;D

Alas for Mr Honda he didn't get his sums right and it just dropped to the bottom of the engine instead, which just goes to show, Mr Honda didn't always get things right.  ;D ;D

Ah but it wouldn't have snapped it off in the first place with the chain hanging upside down  ;D
