sometimes new lifters partially fail if there is too much debris in a fresh engine. I say go thru a few oil changes and see if things improve. Meanwhile for breakin use straight 30 wt oil - you can buy it at discount auto. Basically you want a oil with no detergent and you want to drive it easy while you have the straight weight oil in it. Once you switch to regular oil you can progressively drive it harder.
