I would like to know if you had the passance of waiting for the escape to be decontaminated, but the escape will always throw smoke until the waste is completely burned in the escape.
The second, when disarming you must determine the exact cause of the burning of the oil. If they are valve stamps, the oil excess is seen in the enough of the valves when the multiples are removed or the cylinder head is disassembled.
When the butt is disassembled, the valves seats are always noticeable when this is the cause of smoke and burning oil.
If the entire head of the piston was wet and the best is suspected of checking the old rings by introducing them into the cylinder and measuring them in the piston slot comparing with the thickness of the manual. The same must be done with the piston you have to measure it in the cylinder and you have to measure the new rings in the cylinder and in the grooves according to the manufacturer's thickness to be sure.
If everything is fine, the stamps too and do not have the valves can be set up for sure and it would only be waiting for all the oil in the escape.
