I checked through our database and both codes are not listed. Are you sure the codes are correct?

Good morning.

From your description, it sounds like you have coolant in the combustion chamber of the gas engine and that is producing the white smoke you see and the noise.
I would have a shop check the cooling system for you as it sounds like you have internal engine damage from a possible bad head gasket.

By the way, white smoke is coolant, if you were burning oil, it would be blue.

Seems like your con-rod bearings gave way causing the noise. Such instances are usually due to lack of oil in system or a drop in oil pressure. Ask your mechanic if there are any signs of clogging of the oil strainer due to sludge accumulation.

Rebuilt engines are supposed to be almost new as worn or bad components are replaced with new ones and should function like a new engine.

0W20 might be a little light for hot weathers but still I do not believe that is the cause of your problem as the mileage you have is not too high. I too would advise on a higher viscosity oil, preferably 10w30 or 10w40 due to your weather.

I would also advise against using oil additives if your are using any now.
