Piston Failure

My magnum did the same thing! Smoking from the exhaust and blowing smoke out of the breather. It ended up only being a failed headgasket. The compression was leaking into the crankcase and blowing smoke out under throttle. And on decel it was pulling oil into the cylinder and smoking from the exhaust.
