Am looking at buying a used truck and have found a 2015 Chevy Silverado Crew Cab w/EcoTec3 5.3L V8.

Carfax shows service at 66,065 miles where the lifters were replaced. Odometer shows 66,129.

Does the lifter/AFM issue cause any other damage that I should be looking for? What steps can be taken to prevent the damage from happening again (delete or remove the AFM)?
