Dealer-Trained Master Technicians | Since 1958 **Chevy Silverado / GMC Sierra Timing Chain Problems Edmonton (5.3L / 6.2L V8)** Beyond the AFM lifter failure, the Chevrolet Silverado and GMC Sierra with the 5.3L or 6.2L V8 can also develop timing chain guide wear at very high mileage — particularly on vehicles where AFM-related oil contamination has degraded chain lubrication. Auto Imports assesses Silverado timing chain condition in Edmonton.

Timing chain guide wear occurs at very high mileage (200,000+ km) — less common than the AFM lifter failure. AFM-related metal debris can accelerate chain wear. Cold start rattle at high mileage warrants inspection.
