I visually checked the exhaust- looked ok, but it could be coming from where the exhaust manifold connects to the y-pipe-, or at the head itself, I can't tell exactly, but it is in that area that I hear the sound. I'm going to run a bottle of injector cleaner through it, and do the oil- flush stuff when I change oil, see if that frees a sticking lifter, if that is the culprit.
