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.

I don't see those plug being lean. I usually see that type of gaske failure as detonation, but those gaskets are junk. It's possible if the manifold isn't very good that one cylinder could be lean and that killed the gasket. Plus, it's hard to see things like that on plugs and gaskets in pictures.
