Head Gasket sorted out.     Head  tested&skimed £50 (cash in hand) , new 1.2mm head gasket for £30 from eBay Old bolts as they do not stretch and are spot on 15.5cm long every single one and there is TEN of them not 18 or 16.    Anyway, now I need to clean all injectors as not efficient and has got low performance and need new washers as one of them leaks.    Engine is taping and smoke comes out.
