That sounds like balance shaft or timing chain to me. It didn't make that sound before the head gasket was done? When you removed the timing chain tensioner did the back chain guide pivot freely?

Stupid question, but you released the ratchet in the tensioner by removing the 13mm hex head bolt and spring from the tensioner before you put it back in, right?

You still don't understand. This is like trying to explain calculus to a clam.
