It can show up in rod bearings....

If the problem didn't exist, and now it does, something happened. I've seen upper bearing shells beat up to the point they just fall out of the rod.
Fly poop on spark plugs? Fuel change? Verify timing and TDC marks? Try another known good timing light?
Just reaching here.
