What is this ticking/tapping noise?

Seems to be more pronounced after I recently used Mopar Combustion Chamber Cleaner. Clearly audible in the cabin with the windows up, and seems most prominent from the passenger valve cover.

Thanks!

Too inconvenient to pull the valve covers now, not that that would tell me anything about the lifters. I burn some oil so I check it regularly. It's always been in the hash area of the dipstick.

Had the same thing with a 98 formula. Turned out the roller on one of the lifters had broken in half. It still felt good. Maybe down a little on power but idled right or seemed to. Anyway it took out the cam, crank, and tore up the block by destroying the lifter bore. Good luck.
