What's That Ticking Noise Coming From Your Hemi?

If you own or drive a Dodge Ram truck with a Hemi engine, you may have experienced an annoying ticking or tapping noise coming from under the hood. This ticking is often most noticeable at idle and tends to increase as the engine warms up. While a ticking Hemi can be alarming, in most cases it is not a major cause for concern.

Potential Causes of Hemi Ticking

Some of the common culprits behind Hemi ticking noises include:

• Exhaust Leak - A small leak in the exhaust manifold or gaskets can allow exhaust gases to escape and cause a ticking sound.
• Lifter Noise - Hydraulic lifters that bleed down can make a ticking noise that goes away at higher RPMs.
• Valve Train Noise - Excessive valve lash can enable valve train components to tick despite no loss of performance.

When to Worry About Hemi Ticking

While ticking is usually harmless, pay attention for any changes including:

• Ticking that turns into a knocking noise
• Loss of engine performance
• Check engine light illumination

FAQs

Why does my Hemi engine make a ticking noise?

Common causes of Hemi ticking noises include exhaust leaks, hydraulic lifter bleed down, and excessive valve train lash. The ticking tends to be most noticeable at idle and quiet down as engine RPMs increase.

Is the ticking bad for my engine?

In most cases, mild Hemi ticking on its own does not cause any engine damage or performance loss. However, you'll want to address the underlying cause, especially if the noise gets worse, doesn't go away when warm, or is accompanied by other symptoms.

Can I fix the ticking myself?

Depending on the cause, you may be able to fix minor exhaust leaks, adjust valves, or replace hydraulic lifters on your own. But diagnosing the root issue can be tricky, so you may need to bring it to a professional mechanic or dealership.

Is Hemi tick covered by warranty?

If there are no related engine problems or error codes, ticking from worn components may not be covered under the powertrain warranty. But factory defects causing severe ticking issues may be covered under basic or extended warranties.
