Sad story.
I had such cases with the customers while working in a position of workshop manager. It happens when engine sucks in water inside the cylinder. But usually engine even not starts after that.
In your case I would better fix an original engine or would purchase remanufactured one from certified workshop with the warranty. It's more expensive, but with minimum risk.
Try to get back to a seller and talk to him.
Had the motor about nine months but not to worry I can use the rods out of the old one with new rings and shells so it'll be a good motor when done
