I have just notice an oil leak from the RS coming from the proximity of the cam oil seal (at the vernier end) - purchased new oil seal thinking that was the problem but when I was undoing the cam bolt that holds the vernier on oil came flowing out of the cam where the bolt locates - i.e. from inside the cam where the thread is ??

Has anyone heard of this before - is it actually possible cause as far as I was aware the cam is made from a solid billet of metal and is not hollow - maybe it is but can anyone help, explain ?? or suggest my next step - I assume remove cam and inspect but I find it hard to understand at the moment

 

hi m8,have seen that many times before,thats perfectly normal,when puting bolt back in,remember and put thread lock on the bolt threads,once torqued it will be fine.

 

Cheers m8 - for once a simple fix
