This warrants further investigation, burning oil can be a multitude of things, head gasket, valve guides, valve stem seals, rings etc etc
If the oil slinger rings are broken they may cause bore scoring so it's a bad idea to run it
Sorry I can't advise on anywhere in Swansea but I'm sure someone will be along soon
That's bad luck, hopefully it's something not too costly as it could work out cheaper sourcing a replacement engine
Good luck and
