Replace the broken push rod and set valve clearances to specs and see if the problem clears.

has it been smoking for a long time? As in habitual smoker...engine rings could be worn.

If not, only recent problem them it is related to push rod problem, it would seem.

Missing intake push rod will cause a vacuum effect in that cylinder pulling oil past the rings and causing oil usage and smoke when expelled out the exhaust into the hot muffler.

I agree with IL Engine........ Just like a cylinder on a car engine that has a bad plug.... It is not firing to burn fuel and it's collecting oil in the cylinder so that has to go somewhere.........
