Re: 1996 Cutlass supreme engine knock/click

Welll the ticking I would say is your lifters.
Some of those other noises are a bit more concerning to me though.

Kinda sounded like it had an exhaust leak and maybe even a rod knocking....

I'd try some engine treatment that goes into your oil to clean lifters and oil passages.

I like Seafoam injector cleaner/oil stabiliser. Only take 2-3 onces in your oil, should clean thing pretty good.
Does thin your oil though, so a oil change after you've driven it a little wouldnt hurt. Then you can add a couple onces to the clean oil to clean more varnish from the lifters.

If it doesnt clear up, could also be a bad lifter. These lifters are very noisey to begin with when cold IMO.
