Ofcourse, that would take the knock out. But before you do that try lucas. I had the same problem with my buiick park ave. and I used the lucas motor oil treatment and I ran it on the highway a couple of time and it stopped the knock. It works because lucas is so viscous that it lubricates everything for a very long time.
 
It could be several things worn Big End (Connecting Rod ) Bearing could mean the start of a much larger problem. Or if it is Piston rattle it might last for years or it could ventilate itself tomorrow
With out hearing the knock it could also be a number of other things
so best get it checked out very soon
