Could be the old sticky valves m8.. very common problem on the 1.2 6v engines

i did have the BMD engine and kno of others who did aswell..

had to strip the top end down.. head off.. set of new valves, grind them in good,, get it sparkling with a new head gasket and stuff n build back up.. should be minted :D
