Just listening to the cranking without watching the video...it almost sounds to me like you have a dead cylinder (compression wise). That cranking should sound like: nah, nah, nah, nah, nah, nah, nah, nah, nah, nah, nah, nah (steady & consistent (equal force needed to push each cylinder against the compression cycle)) but yours sounds more like: nah, nah, nah, nah, nah, nah, nah, NUH, nah, nah, nah, nah, nah, nah, nah, NUH.

I'll be honest if you have done a head gasket and you have a slipped or slipping liner, it could have already beaten the head gasket to death again and you now have a dead cylinder (again)....same exact thing happened to me on my old 03 I think it managed to last a month or so before it did that to it....ended up having to get a salvage motor that was good (heard it run from cold to fully up to temp listening for slipped liner - they usually can't be heard from cold start but can once warm unless they are REALLY loose) and totally rebuilding it and pinning the liners to make sure it wouldn't happen on that one.
