Start up rattle on 4200 - With sound

Just realised I never concluded this thread.

As mentioned elsewhere, the noise appeared to be a weak hydraulic tensioner that was bleeding out pressure, causing a slack chain on start-up.
I replaced all the chains, tensioners, guides and fixed the front cover leak with a new gasket and crank seal as well. All seems good now. I do have a slight noise if left for a month or so without running but that is only a second or two, not what is heard on the video clip I attached earlier in the thread.

Some pics for interest:
