ClearTheCode guidance (Ram · Engine & drivetrain)

Summary: For Persistent Hemi Tick on my 2018 Ram 1500 - Exhaust Manifold?, work through these steps on your 2016+ vehicle:

1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
5. Test the common fix — follow model-specific service procedures; one change at a time.
6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.

Owner reported: My 2018 Ram 1500 Laramie, with the 5.7L Hemi, has developed a noticeable ticking sound, especially when cold. It seems to quiet down a bit once the engine warms up, but it's still there.

I've heard this is a common issue with these engines. It sounds like it's coming from the exhaust manifold area. I'm worried it might be something serious. Has anyone else experienced this, and what was the fix?
