Also can someone comment on this chain slack?

Looked fine to me when I watched your video you first video. Was waiting for someone else to comment first though.
What does the service manual say?

Couldn't find it in the service manual.

I just checked 2 manuals and also could not find a recommended deflection.
How many mm would you say you have from:
A) resting to pressed in fully
B) pulled out to pressed in.

That's pretty normal - there's no adjustment anyway. They're pretty loose from standard, and there's good contact all the way around each sprocket so no real chance of it skipping.

Earlier 308's had a chain 'tensioner' or slider which was actually on the wrong side for a tensioner, which holden later decided wasn't necessary.

You can buy gear sets that decrease chain slack so that cam timing is more precise. Using .002" undersize cam bearings also helps to take up some timing chain slack. I wouldn't worry about it.

Hmm I estimate 12mm using the callipers. I also turned the engine backwards a small bit and then turned correct direction until I saw the rotor button turn. I estimate engine turned 6 degrees turning (using iphone level) before I saw the rotor button turn.

12mm is a bit... a new chain's cheap and may take up some of that slack? I got one for under $20 from nason.

A good new set you struggle to get the sprocket on the cam they are so tight they loosen up pretty quick but 12mm seams a lot of slack

I might try that measurement again, but think I'll just get a new chain for that price!

Done. Arrived today and fitted.

Looks like the same amount of slack
