Owners of 2021-2025 Jeep, Dodge, and RAM vehicles may experience an engine ticking noise, prompting concerns about engine health. This issue, often linked to hydraulic lash adjusters, is detailed in Technical Service Bulletin (TSB) 9100614, issued on June 18, 2025. The bulletin provides crucial guidance for technicians to accurately diagnose the source of the noise, specifically distinguishing between normal lash adjuster behavior and actual malfunctions.
The TSB highlights that misdiagnosis can lead to unnecessary replacement of functional components. For instance, a 2023 Jeep Wrangler engine ticking noise might not always indicate a faulty part. Understanding the design characteristics of both intake and exhaust lash adjusters is key to proper diagnosis.
Symptoms
The primary symptom reported by vehicle owners is a "ticking noise coming from the engine." Technicians investigating this complaint may observe what appears to be "spongy" or "stuck hydraulic lash adjusters." These observations can sometimes lead to incorrect assumptions about component failure.
Important Warnings
TSB 9100614 includes critical instructions to prevent unnecessary part replacements:
- "Do Not Replace EXHAUST lash adjusters" if they are compressible but still exert a reactionary spring force during compression and return to full expansion without external compression. Exhaust lash adjusters are designed to be compressible by hand.
- "Do Not Replace INTAKE lash adjusters" if they feel very firm and difficult to compress. Intake lash adjusters are designed to be non-compressible by hand.
These warnings underscore the importance of understanding the normal operational characteristics of these components before deciding on a repair.
Diagnosis and Trigger Conditions
Proper diagnosis of the engine ticking noise, such as a 2023 Jeep Wrangler engine ticking noise, requires careful evaluation of the hydraulic lash adjusters. The bulletin clarifies that exhaust lash adjusters are designed to be compressible by hand. If an exhaust lash adjuster is found to be
