Check to make sure you don’t have a scored cylinder walls. It’s looking like it. Do a compression test. Easiest way to tell. Then a boroscope.

Is there a lot of oil around the spark plug? Could be the plug seal. Worst case engine is toast

Thanks Jay,
cylinder walls is fine,
I had replace spark plug 3 times and still the same.
regards to engine, as per my experience, it should in different cylinders and oil burning and exhause smokes become more in highways....
