White smoke = antifreeze/water - tranny fluid

Blue smoke = oil

Black smoke = fuel (rich)

Another thing to think about- if they used oil on the rings to assemble the engine, might be the oil between the rings burning off. I always WD40 the cylinder walls and put the pistons in dry. Never had a problem this way. Just with fram filters.

ALSO ONE TIME MY ENGINE WAS SUCKING OIL THROUGH THE VALVE COVER, THROUGH THE PCV VALVE INTO THE CARB.. POSSIBILITIES,, WRONG PISTON WALL CLEARANCE, RING GAPS, VALVE GUIDE CLEARANCE.. OR BEAT THE BAT HELL OUT OF IT AND SEE IF THE RINGS SEAT..... GOOD LUCK...

a blown head gasket would the cause to smoke on both sides, and how would fuel get in the oil, to much jetting in the carb, the plugs look good , no water in the oil, the motor only has about 3 hours of running time, but i never seen a new motor smoke like that even if you need to break in the motor, for the rings to seat,

A blown head gasket would burn oil on the side that was blown. Is it burning on both sides? Were the valve seals replaced? Sometimes the little things get overlooked. The intake could be leaking and pulling oil in from the valley.
