Did you replace the valve stem seals in the cylinder head?.. Sometimes the oil passes through the valve stem on the intake stroke and mixes with the fuel mixture. and the valve guides should be checked for excessive wear...Also the oil control rings on the pistons could have been scratched or have a flat spot on the surface area.
