Hi there. The engine has valve guide oil seals that prevents oil puddling up onto the valve and allowing the valve to suck in the oil. The valve guide seals are leaking too much and causing excessive oil to enter the combustion chamber. I recommend replacing the valve guide seals. This will require to remove the cylinder head. When the cylinder head is off, I recommend checking the valve to guide clearance for excessive wear.
