My recent purchase

Was the car stood a long time before you bought it? I am wondering if it's corrosion from being stood so long with no antifreeze, but sorry , no real answers for you !

I hope it's sorted now

Mike,

Have you checked if the thermostat is clogged shut? This could build up
pressure in the block.

If you have sufficient pressure to blow a core plug, but no pressure at
the radiator cap, there are perhaps two reasons
One .- excess pressure from a head gasket/block.
Two:- Blockage to or at the radiator.
Check the thermostat and the bottom of the radiator. If both are blocked the
core plugs take the brunt of the pressure.
Hope this helps and happy digging.
