Re: valve cover leak
Dealer pointed out a slight weeping from the front of the driver's side valve gasket on my roadster last time it was in for an oil change. It was out of warranty, but we discussed it and the mechanic lightly tightened down all the valve cover bolts. Unfortunately the car went into storage soon after (I change the oil before hibernation) so I don't know if that solved it, but this seems to be a common problem. I've noticed just a little oil in the same place on my son's 2007.
