by

The HEMI tick is a common concern among owners of Dodge SRT Hellcat and Scat Pack models from 2015 to 2023. Understanding how to diagnose this issue can save you time and money, as well as prevent further damage to your vehicle. This article will guide you through the steps to identify and address the HEMI tick in your engine.

What is HEMI Tick?

HEMI tick refers to a ticking noise that can be heard from the engine compartment of Dodge vehicles equipped with a HEMI V8 engine. This noise can be attributed to various factors, including valve train issues, exhaust leaks, or fuel injector noise. Recognizing the symptoms early can help in diagnosing the underlying problem.

Common Symptoms of HEMI Tick

  • Audible ticking noise, especially at idle
  • Noise increases with engine RPM
  • Potential loss of power or performance
  • Check engine light may illuminate

Steps to Diagnose HEMI Tick

Step 1: Gather Necessary Tools

Before you begin diagnosing the HEMI tick, ensure you have the following tools on hand:

  • Mechanic’s stethoscope
  • Basic hand tools (sockets, wrenches)
  • Torque wrench
  • OBD-II scanner

Step 2: Listen for the Tick

Start your engine and allow it to idle. Use a mechanic’s stethoscope to pinpoint the location of the ticking noise. It is essential to determine whether the noise is coming from the valve train, the exhaust system, or another area of the engine.

Step 3: Inspect the Valve Train

With the engine off, remove the engine cover to gain access to the valve train. Check for loose or damaged components, including:

  • Valve covers
  • Pushrods
  • Rocker arms
  • Valves and springs

Step 4: Check for Exhaust Leaks

Inspect the exhaust manifold and connections for any signs of leaks. A leak can create a ticking sound that may be mistaken for HEMI tick. Use a spray bottle with soapy water to check for escaping air, which will create bubbles at the leak site.

Step 5: Scan for Diagnostic Codes

Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) that may indicate a problem with the engine. Pay attention to codes related to misfires or performance issues, as they may provide clues to the source of the ticking noise.

Potential Causes of HEMI Tick

  • Worn or damaged lifters
  • Faulty pushrods
  • Loose rocker arms
  • Exhaust leaks
  • Fuel injector noise

When to Seek Professional Help

If you are unable to diagnose the issue or if the ticking noise persists after your inspection, it may be time to consult a professional mechanic. They will have the expertise and tools necessary to accurately diagnose and repair the problem.

Conclusion

Diagnosing HEMI tick in your Dodge SRT Hellcat or Scat Pack can be a straightforward process if you follow the steps outlined above. By being proactive and addressing the issue early, you can maintain the performance and longevity of your vehicle.
