Sounds like lifters/valves almost...no matter what that's a bad noise!

Agree,it sounds like a valve. The safest thing to do is have it flat bedded to a mechanic but if it were me, I would look at the oil filter to see if there is any metal in it. If the filter is clean, then I would check the timing with the Durametric. If the timing is good, I would get under the car while its running and use a stethoscope to try to pinpoint where the sound is coming from.
