Piston slap... Is it fatal?
I have the 5.3 with the infamous cold start piston slap. With the arrival of the colder weather it has become much more pronounced than in the past. Will this eventualy turn into broken piston without intervention or can it be left as is for the next 75K miles? it has 135k miles now.2000 GMC YUKON SLT, 5.3L tow pkg, G80 rear/w 3.73 gear
