Put a good motor flush in the oil, follow the directions, and change the oil. It needs a internal cleaning chemically, even if you still hear it I wouldn't;t worry, but that's why you need to use the right viscosity for the time of year it is. With no loss of power, a waste of money to fix.

Get a hold of a shop manual and see if its normal or not- some types and times of intermittent knocking is normal.
Plus I would have a compression test done (around $50 and worth every penny..) and change the oil and add a pint or quart of Lucas.- Does wonders.
Good luck and stay on top of it before it develops into something if anything worse!
