or melted piston due to under performing AMM and high miles. Usually there is molten piston on the cylinder wall requiring a bore job with new oversize pistons. Done right good for another 200K. just pull out the plugs, it's usually #1 that is melted. look in the cylinders with a bright led light, or a borescope to be fancy. you will see the wreckage.
Hole in piston overpressurizes PCV system and fills intake with oil, thus the smoke.
Usually rod knock motors don't smoke until the rod comes out.
