Gary,

It is really important to not overfill or underfill the oil.  If there is too much the crank will whip it up into a froth and then air will get in the oil galleries.  If there is not enough it will suck air and eat the bearings.  If it were me I would get the oil at the correct level and hope there has been no bearing damage from the oil getting whipped up.

Answer
Gary,

If there is lower engine knocking like the bearings are worn down, as in loose tolerances, or a spun bearing.  But, in either case there would be low oil pressure as your first indication.  So, if the oil light is not on or your gauge is not reading low you should be fine.
