replacing the O-rings is a bit of a job but can be quite therapeutic for a couple of hours

I have done 3 valve blocks in my time and it is not that bad.
I have found though that those push to seal fittings require quite some effort once they have been in place for a while to get out and inevitably you can damage one of the airlines. Not so much bend or break them but scratches develop on the surface which does not help in creating a proper seal. Running new airlines is quite a bit of work but you can do one at a time and (IIRC 6mm) airline is not that expensive.
Keep it up! you'll get it sorted
Cheers,
