2016 Jeep Cherokee KL 2.4L Engine Ticking & Oil Consumption

Vehicle: 2016 Jeep Cherokee Latitude

Hello everyone,

I own a 2016 Jeep Cherokee Latitude with the 2.4L Tigershark engine, and I've been noticing a distinct ticking noise coming from the engine, especially when it's cold. It sometimes quiets down when warmed up, but not always completely. On top of that, I've been going through a surprising amount of oil between changes.

I'm checking the oil regularly, and it seems to be consistently low despite no visible leaks. The mileage is around 80,000. Is this a common issue with the 2.4L engine, and what should I be looking for? No check engine light is on currently.

Any advice would be greatly appreciated!

The ticking noise and excessive oil consumption in your 2016 Jeep Cherokee's 2.4L Tigershark engine are unfortunately well-documented issues. This engine generation has been known to experience problems related to its valvetrain and piston rings, leading to these symptoms.

Possible Causes:

  • Valvetrain Noise (Ticking):
    • Hydraulic Lash Adjusters (HLAs): These components can become clogged or fail, leading to excessive valve clearance and a ticking sound.
    • Camshaft/Rocker Arm Wear: Wear on these components can also contribute to valvetrain noise.
  • Excessive Oil Consumption:
    • Piston Ring Design: The 2.4L Tigershark engine's piston ring design has been implicated in allowing oil to bypass into the combustion chamber, where it burns off.
    • PCV System Issues: A faulty Positive Crankcase Ventilation (PCV) valve or system can contribute to increased oil consumption.
    • Valve Stem Seals: Worn valve stem seals can allow oil to leak past the valves into the combustion chamber.

Diagnostics & Steps:

  1. Oil Level Monitoring: Continue to monitor your oil level diligently. Keep a record of how much oil you add and how frequently. This data is crucial for a technician.
  2. Oil Type and Viscosity: Ensure you are using the correct oil type and viscosity as recommended by Jeep (typically 0W-20 for this engine). Incorrect oil can exacerbate issues.
  3. Listen for Noise Origin: Try to pinpoint where the ticking is coming from (top of the engine, front, etc.). This can help a mechanic narrow down the problem.
  4. PCV Valve Inspection: A mechanic can inspect or test the PCV valve for proper operation.

When to See a Shop: It's highly advisable to take your Jeep to a dealership or a reputable independent shop specializing in Jeeps. They can perform:

  • Oil Consumption Test: A dealership can perform a controlled oil consumption test to officially document the issue. This is often necessary for warranty claims (if applicable) or for determining the severity.
  • Valvetrain Inspection: They can remove the valve cover to inspect the camshafts, rocker arms, and HLAs.
  • Compression/Leak-Down Test: These tests can help assess the health of the piston rings and valves, confirming if oil is being burned due to internal engine wear. Some owners have even had engine replacements or significant repairs under extended warranties or through service campaigns for these issues.
