Just re read your whole post, Ive had about the same trouble, your spring pressure might be flexing the cam or the core material is sub standard. Either way your probably gonna wear something out prematurely.

IMO your near needing a billet core, at least thats what I ended up doing.

Or what rockers are you running, have you inspected them?


Ya got a vid of this moaning? Is it like "My legs caught in the combine" moaning?.... ummm "God im too drunk" type moaning? The wifes like "Thats it, thats the spot" moaning?

We need a vid. Like CAB wrote, its talking to you but in what way?

Or you could just make a vid of what you think it sounds like, like this.

BUT REALLY you seem to know its not natural.

Last timing belt I put on, I couldnt follow the tensioner arrow and it was moaning letting me know I f-ed up and had I way too tight.
