| I own a 2004 chevrolet silverado 1500 4x4. i have a broken rear exhaust manifold bolt on the left side of my 5.3 v8. i hear this is an extremely common problem. my local dealer wants $1,600 to fix it because you do need to pull the aluminum head to repair it!! i completely agree with the head needing to be pulled, but i believe that gm needs to step up and fix this extremely common and ongoing problem. it is definitely a manufacturer defect!! | |||
