I'd be willing to wager that its a broken valve spring.. Sounds like the piston is bouncing the valve off its seat. Could also be a shattered lifter, or even a wrist pin/ small end rod bushing.
The dealer couldn't tell what that was?? Doesn't surprise me.
Been there. Contrary to what you may have been told I can repair that.
DO NOT RUN THE ENGINE ANY LONGER!
