GM giving you the run around with their "selective" hearing? As we know many engines have #1/#2 cylinder overbore resulting in piston slap "knocking" noise and excessive oil consumption. Join the party it's time to make your case heard (like that knocking noise). even if you car/truck is out of the warranty period YOU STILL HAVE RIGHTS IN THE CASE OF THIS DEFECT!

What about those of us that are out of warranty. Will this help us?

I just took my heads off for sounds like this that I couldnt track down. What should the exact bore size be?

 

Hummm...???not sure???. But I did write GM CEO Wagoner for exact specs. Maybe they'll send them to me. Maybe this will help
