Incorrect tolerances between cylinder bore diameter and piston diameter (i.e. piston slap). This allows the piston to rock/tilt in the bore.
Dirt getting past your air filter and into your engine.
Extremely low oil levels.
Insufficient ring end gap.

Well it did slap alot when cold? I guess that's what caused it. I don't think it was the filter or oil it was just the one #7 piston wall. Now I need to boar it out. Somanabitch
