Hey guys love Chevy! my Silverado has 200,000 started some rattle like 45 mph 2000 rpm was thinking timing chain guide or cat breakdown but not sure also thought valve problem smokes a lil think it's burning oil either way it's gonna need some breakdown soon ,really don't want to go back stock if I have to start spending (have a 03 suburban also) love em
I'd love to just buy a 6.0and drop in but sounds like too much to switch over
