My car has 7600 miles on it now. I only use premium gas, and synthetic oil. the noise comes and goes - only at idle, and as far as I can tell, only when it gets hot. I live in HELL - AKA Phoenix, Az., and maybe it isn't hot enough where you live. I'm not worried that if something happens, he won't take care of it, I am mainly curious how many others are experiencing this. The sad part is we're going to HAVE to use the dealer for oil changes, and that means they'll be able to charge a high priice.

I will pay particularly close attention to engine noises now, but I gotta be honest, that lobeless cam business sounds screwy to me...why would it even be called a cam if it had no eccentrics (lobes)???
Another thing, the fact that you are running synthetic at only 7600 miles troubles me.
When, mileage wise, did you originally change to synthetic ? I have 3 dealerships near me and they all insist that you stay with conventional oil for the first 15k miles before making the choice to go synthetic.
Lastly, I'd bet a dollar that, (if there isn't any mechanical problem/damage to your car already) if you swithed to a conventional oil, properly weighted for your climate, that your noises would go away. It wouldn't be too expensive of a test anyway, considering were talking about a 40k car.
