Hello,
There is a possibility that the old motor was not burning properly and you have carbon build up on the O2 sensers. A poorly functioning O2 senser will not allow the Fuel/Air mixture to work as you give it gas under load. You could have multiple O2 sensers too.

Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.

Knocking can be caused by a bad bearing somewhere in the engine. When the engine is accelerated it might go away due to higher oil pressure.
When did you have the oil changed and how many miles does it have?
Is the knocking rapid (5 or 6 times a second) or periodic (1 or 2 times a second)?
Some knocking is due to low octane gasoline if you experience it at highway speed.
Good luck on solving this knocking problem.
