2010 5.3 knock, *VIDEO*
2010 5.3 knock, *VIDEO* just wanting to know what y'all think, bolt on 5.3 silverado, did BTR dod/afm delete. BTR stage 2 truck cam, 3rd pull it developed this knock. Went home checked everything, talked with btr they sent me 8 lifters and i changed the driver side because thats where it came from. drove it easy and 800 miles it came back. Normally only did it at WOT or only under a load. When i traded truck in it was doing it constantly. just wondering what y'all might think it was.
