If your vehicle has a warning light, leak, abnormal noise, rough running, overheating, reduced power or another concern, we recommend diagnosing the actual fault before replacing parts.
COMMON COMMON ENGINE ISSUES
Common concerns for the How to Diagnose GM AFM / Ram MDS Lifter Failure include:
- Rhythmic ticking or tapping: begins on one side of engine — the first sign of a collapsing lifter
- Misfire codes: P0300-P0308 in the engine’s check engine light — indicates a cylinder not firing
- Oil consumption: low oil between changes can accelerate lifter failure
These problems can become more common as mileage increases, but mileage alone does not prove a component has failed.
SYMPTOMS, MILEAGE AND REPAIR RANGES

HOW TO DIAGNOSE GM AFM / RAM MDS LIFTER FAILURE EDMONTON — COMPLETE GUIDE FAQ
How do I know if my truck has a lifter failure?
A rhythmic ticking or tapping sound from the engine that doesn’t go away — combined with misfire check engine codes — is the classic AFM/MDS lifter failure signature. Stop driving and have it diagnosed immediately.
Is AFM/MDS delete better than replacing the failed lifters?
Yes — the delete eliminates the failure mode permanently. Replacing failed lifters without the delete just resets the clock. We strongly recommend the delete ($3,000-$6,500) for any vehicle past 100,000 km.
