Its possible that the O2 sensor was damaged by the movement or banging of the exhaust pipe. But seriously doubt it, and no way on the cat. Its probably just something that happened.

He put a used engine in it for what reason?? Did the old one start burning tons of oil? Generally when an engine blows up, there is a large amount of oil thrown into the exhaust. This will clog up the cat in a bad way. It will also effect the O2 sensor because there is little to no exhaust flowing through the system if the cat is clogged. I would reccomend replacing the catalytic converter. If the O2 sensor still throws a code, you can pull it out and clean it thoroughly and put it back in. This should fix your problem. Good luck.

check the 02 sensor wire many times used engines get the plugs hacked off, If your 02 wires have been spliced you might start simple, check if it's wired correctly. If wires are spliced with crimped connections remove them and solder them together. If you swapped a different year engine it probably is wired differently (you may have to change the plug on the end. See if you have a good sensor and check it. if you were not getting a code when you had the old engine in it. I would clean the old one, then check for codes, clearing the codes each step I mentioned. Good Luck! :o)
