i have a 2000 silverado with the 5.3L and i had 156,000K with the piston knock. while driving the connecting rod bent and smashed the piston into the crank shaft. so i bought another 5.3L and put this engine in and i have the same problem with cold knocking every one else is having. im kind of pissed off that GM just pushes the problem aside and wont address it but what can you do?
