Maybe a bad oil pump, no oil pressure, isn't good.

The smoke probably came from the leaky poppet valves/FPR/nut kit and oil wasn' changed-No oil pressure -check the connection on the oil pressure switch beside the distibutor if there's no tapping or knocking noises present. Cylinder washed down?????? Do a compression test both wet and dry and also a cylinder leakage test-And check the PCV system
