Hi Keith
You're right, it is moving because the builders failed to fix the new joists properly a few years ago. That is the root cause. It was fine before. The builders used inadequate 2 or 3mm wood screws. They had nothing else to hand and simply couldn't be bothered to do anything better. Cowboys.
There are several repair methods suggested using steel screws or bolts or oak dowels. Provided the method chosen does not crack or split the old oak, and the fixings are strong enough, I'm sure it will be fine. I will monitor carefully after repairs to check for further movement.
I'm also aware that with coach screws the guide hole must be drilled first to the correct diameter. If it the diameter is insufficient, the coach screw will shear or jam and the wood may crack or split.
