Also concerned with all the knock/slap when you first started it up. Could be a bad timing chain tensioner or chain guide broke. Both not uncommon.
I'll get a video of the sound from under the car this weekend. The sound gets worse as you give it some gas.

I'll try and see if I can pinpoint the sound this weekend. I hope it's something that won't require a new engine. I've looked around and they aren't cheap.
