Yea a friend of mine spun a rod bearing and sounded like that... rod knock and it kept getting louder. Engine could be toast!
Their going to have to pull the engine and practically rebuild the bottom end.
That is if it turned out to be that.
If they where concerned with a big tow bill their about to eat the farm ! Probably going to cost them half of what you bought it for !
Look up rod knock on you tube you'll see lots of different examples.
Their was a time you could put load on the engine and hold the brakes and I forgot if the knock is supposed to get quieter or louder to confirm but I'd give it a shot. Lots of info on YouTube for rod knock. I'd suggest looking on how to diagnose if it is.
