Please help with ticking noise

My bet is with Dartswinger70. Start her up with valve cover off and a towel stuffed next to head to catch oil, when she is cold and check valve train stuff.

When I read back on this thread, I suppose that even if you replaced all the lifters, it's possible to still have one that pumps up slow. Seems unlikely, but possible. You are doing/ have done, the things necessary to track the tick down. I have had some luck with additives like Rislone or Hyperlube if not to fix problem but to at least confirm or deny one. (Rislone being a solvent, Hyperlube is super thick.....pretty sure I got that right)
