just had timing belt replaced on 1999 1.6 zetec,bent two inlet valves due to bad info,replaced all eight inlet valves and valve seals,new head and exhaust gasket started up,pouring smoke out of exhaust on load.run for about half an hour,still smoking.can you please help?
assuming the valve stem oil seals were fitted correctly when the valves were replaced i would say you have a cracked piston, take out the spark plugs and see if one or all are black and or oily - if its only one then it would indicate a piston! if its all then you have an oil issue at the inlet?
