So, I've been busy over the past 4 months. What initially started off as 'clean up and maybe a new rocker gasket' grew arms and legs!!
It was clear upon further inspection that the engine top end sealing was poor (i.e. oil was falling out of most of the joints - VVC seals, camladder seal, rocker, etc...) So I ended up taking the plunge and stripping top end down completely. Head off, new stem seals, lap valves, VVC Hydraulic unit overhaul, new belts, water pump, MLS head gasket etc, etc.....and a good degrease and clean on the way.
Anyway, the engine now is finished and looks damn fine. Just need to get it into the car before Stoneleigh.
