Step-by-step: How to Address the Hemi Tick in Your Dodge Challenger or Durango

by

The HEMI tick is a common issue faced by many Dodge Challenger and Durango owners. This article provides a detailed, step-by-step guide to help you address this problem effectively.

Understanding the HEMI Tick

The HEMI tick is often characterized by a ticking noise that emanates from the engine, particularly at idle or low RPMs. This noise can be caused by various factors, including:

  • Exhaust leaks
  • Faulty lifters
  • Oil flow issues
  • Worn engine components

Tools and Materials Needed

Before you begin, gather the following tools and materials to ensure a smooth process:

  • Socket set
  • Torque wrench
  • Oil filter wrench
  • New engine oil
  • New oil filter
  • Mechanic’s stethoscope
  • Rags and cleaning supplies

Step 1: Identify the Source of the Noise

To effectively address the HEMI tick, you need to identify its source. Follow these steps:

  • Start the engine and let it idle.
  • Using a mechanic’s stethoscope, listen closely to different areas of the engine.
  • Pay attention to the sound’s location and intensity.

Step 2: Check for Exhaust Leaks

Exhaust leaks can often mimic the sound of a ticking engine. To check for leaks:

  • Inspect the exhaust manifold and gaskets for cracks or damage.
  • Look for any signs of soot or discoloration around the joints.
  • If found, replace the damaged components.

Step 3: Inspect the Lifters

Faulty lifters can lead to a ticking noise. To inspect them:

  • Remove the valve covers.
  • Check the lifters for wear or damage.
  • Replace any faulty lifters as needed.

Step 4: Change the Engine Oil

Old or low engine oil can affect the lubrication of engine components, leading to noise. To change the oil:

  • Warm up the engine to thin the oil.
  • Turn off the engine and let it cool slightly.
  • Use an oil filter wrench to remove the old oil filter.
  • Drain the old oil from the oil pan.
  • Replace the oil filter with a new one.
  • Refill the engine with new oil as per the manufacturer’s specification.

Step 5: Check for Worn Components

Worn engine components can also contribute to the HEMI tick. Inspect the following:

  • Timing chain and gears for wear.
  • Piston rings and cylinder walls for signs of damage.
  • Replace any worn components accordingly.

Step 6: Reassemble and Test

Once you have addressed the potential issues, reassemble any components you removed:

  • Reattach the valve covers securely.
  • Start the engine and listen for any remaining noise.
  • Take the vehicle for a short drive to see if the ticking persists.

Conclusion

Addressing the HEMI tick in your Dodge Challenger or Durango can be a straightforward process if you follow these steps carefully. Regular maintenance and prompt attention to issues will help keep your vehicle running smoothly.
