Going to need bigger pictures.
That noise isn't uncommon. Sounds like the timing chain tensioners, or closely related. I pulled and inspected my starter... and unfortunately that wasn't the problem. I'm trying to build up confidence to go the whole 'TDC... pull the green plug... remove the three tensioners... replace... etc". Do a search of the forum, and you'll find plenty of info.
The white smoke? Maybe from the overfill. Likely just residual oil due to the flat6 design. I get it 1 out of every 20 starts.
If you've a Durametric... you can check the cam variances (so I've read). I'm far from the resident expert.
Good luck.
