get in touch with kent, the sam happened to me, one of the followers failed and got lodged in the chamber causing it to wear thr exhaust lobe completely. Kent sent me a new one out in the post within 2 weeks. If they give you any shit put a post up on this forum and we can group together to prove its a common fault. as for running in the cam, the purpose of this is aminly for the followers, they need to compress and fill with oil, I found that the best way is to do this when they are out, means they arnt dry once installed.

Hope this helps mate

p.s. I have onluy heard good things about newmans so that what im getting when funds permit!
