Cams slipped need help setting it right

The key (pun intended) is getting the colored links on marks....see video below.
Once you have it timed the harmonic balancer is keyed to only fit one way on the crankshaft.

I don't mean this in a derobatory way... Did you read up on, or watch any videos on how to
install the timing chain before starting this job?
After everything aligned, and you've released the tensioner, rotate the engine 720 degrees.
2 complete turns. All the timing marks should line up again. I'm not sure if the colored links will
or not, but it doesn't matter as long as the marks do.

Just take your time, and go slow...

 

The colored links won't, not after two crank turns. You will eventually return to all-the-pieces-lining-up again (assuming the timing is right) but it takes on the order of a few dozen crank turns, or about the ninth or tenth time you see the colored chain links go by.

The pictures of the cam sprockets show the links in the right place. I believe if the crank pulley/balancer is removed, you should be able to get a shot in through that hole that shows the colored link and the dot on the crank sprocket. That photo isn't included upthread, and that's the piece I don't trust. The photo of the crank pulley does not show it at TDC, at least assuming the light-colored spot on its edge is the ignition timing mark.

 

Seems to be pretty hard to see in there past the oil seal. My bad. (Maybe I was thinking of pics somebody took before installing the seal.)

 

That’s the pop-mark on the end of the crankshaft?


(Just beyond my funky arrow)

 

I've seen the mark before the timing cover is on.
That's why you should turn it over, before the cover is in place.

 

Ah, yes, that does look like the yellow link.

I was expecting it to be more at the three-o-clock position. Was the camera just held at a funny angle?

 

Need to pull the timing cover again. Looks like you are a tooth off at the crank.

My guess is that your marks were lined up, but you left slack on the wrong side of the chain drive. All of the slack needs to be on the side with the tensioner.
