My 2015 Silverado with AFM (active fuel management) developed lifter ticking, this destroyed the cam shaft and a stuck lifter. Being retired I could not afford a new vehicle, so after recommendations from a retired Jasper engine installer, and another friend that had his engine replaced, I called Ernie, and after the first phone call, he makes you feel warm and fuzzy knowing they are capable of this huge task. I will bring all my repair needs to Ernie’s shop. They are the best. Jasper’s warranty is 3 years or 100,000 miles, parts and labor.
