Introduction

This tutorial provides a step-by-step guide on how to resolve the ticking noise commonly associated with the Chrysler Dodge Jeep Pentastar 3.6 engine. This issue typically arises due to a faulty roller rocker on the camshaft, particularly on the rear cylinder head. By following these instructions, you can effectively diagnose and repair the engine tick, even if your vehicle is out of warranty.

Step 1: Gather Your Tools and Materials

Before beginning the repair, ensure you have the following tools and materials on hand:

  • 8mm socket and ratchet
  • 10mm socket
  • 13mm socket
  • Torque wrench
  • Replacement roller rockers
  • Engine oil (for lubrication during reassembly)

Step 2: Remove the Air Breather

  • Locate the air breather on your engine and carefully remove it to gain access to the intake manifold.

Step 3: Take Off the Upper Intake Manifold

  • Use the 8mm socket to remove the bolts securing the upper intake manifold.
  • Do not forget the two 10mm bolts located at the front and the hidden one on the side.
  • Remove the 13mm bracket that holds the manifold in place.
  • Carefully lift the upper intake manifold off the engine.

Step 4: Remove the Rear Valve Cover

  • After removing the upper intake manifold, detach the vent on the back of the valve cover first to avoid breakage.
  • Remove the bolts securing the valve cover and set it aside.

Step 5: Inspect the Roller Rocker

  • Look for signs of wear on the camshaft. Check for ridges on either side, indicating damage.
  • Wiggle the roller rocker to see if there is excessive movement. If it moves up and down freely, it is likely faulty.

Step 6: Remove the Camshaft Bearing Caps

  • Using the appropriate socket, remove the bolts from the camshaft bearing caps.
  • Carefully pop out the faulty roller rocker from its position.

Step 7: Replace the Roller Rocker

  • Take the new roller rocker and install it in place of the faulty one.
  • Ensure that it fits snugly and does not move excessively.

Step 8: Reassemble the Engine Components

  • Torque the camshaft bearing caps to the manufacturer’s specifications to ensure a secure fit.
  • Reinstall the valve cover, ensuring all seals are intact.
  • Replace the upper intake manifold, securing it with the bolts removed earlier.

Step 9: Reattach the Air Breather

  • Once everything is back in place, reconnect the air breather to finalize the assembly.

Conclusion

By following these steps, you should be able to successfully resolve the engine tick in your Pentastar 3.6 engine. Remember to perform the repairs carefully and ensure all components are securely fastened. After completing the repair, start your vehicle to confirm that the ticking noise has been eliminated. If the issue persists, consider consulting a professional mechanic for further diagnosis.
