I hate to say it but I'd say in the #2 cylinder you need rings. Might get lucky and it be just a bunch of seized oil control rings though. If so, will have good compression and smoke like a freight train. Normally if it smokes more at idle, on startup and the like, then you need valve stems seals. When it smokes with rpm, typically its rings.

Try this, use synthetic oil as it typically burns nearly clear, plus the synthetic properties will break loose the oil rings if seized.
