Hello I'm not sure if the problems are related.

Hello I'm not sure if the problems are related but as soon as I changed the belt my power steering started leeking and the bearing on the pulley squeaks so I did a cheap fix and put stop leak in it. And about 200 miles down the road I parked and stared to hear a knock sounding like it was coming from the bottom end. So I dropped the oil pan and checked for specs or shavings of metal. And there was nothing. I also checked the tourque specs and the rod and cap bolts and they were also or. The rod and crank bearings seem to be fine. And now the noise gets louder when its in neutral or park. So now I'm thinking maybe tourque converter. I'm not sure what it is can you please help.
