Well what has me thinking about the rings is a whole other issue. I have two of these motors. They both make the same noise but the 2nd one didnt make the noise when I first installed it. It only made the noise after it blew the oil out, but prior to blowing the oil the engine ran as quiet as a new car.

I was thinking that the piston skirt is really short and it has pressed in wrist pins. maybe the piston is rocking back and forth and hitting the skirt?

here is the noise that it makes.
