my Toyota Tacoma N300 (2016-Present) has a ticking noise from the engine, what could it be?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to ensure safety during the repair process.

2. Change Engine Oil and Filter

• Sub-steps:
  1. Raise the vehicle and secure it on jack stands.
  2. Remove the oil drain plug using a socket wrench and drain the old oil into a container.
  3. Replace the oil filter using an oil filter wrench.
  4. Install a new oil filter and ensure it is torqued to the manufacturer's specifications.
  5. Reinstall the drain plug and torque it to the specified value (typically 30 ft-lbs).
  6. Fill the engine with the recommended oil type and quantity (typically 0W-20 for Tacoma).

3. Adjust Valve Clearance

• Sub-steps:
  1. Remove the valve cover using a socket set, taking care to disconnect any necessary components.
  2. Check the valve clearance using a feeler gauge; compare it to the specifications in the service manual.
  3. Adjust the clearance by loosening the rocker arm bolts and repositioning the shims as needed.
  4. Reassemble the valve cover and torque the bolts to the specified value (usually around 10-12 ft-lbs).

4. Inspect and Replace Timing Chain/Belt (if necessary)

• Sub-steps:
  1. Remove the necessary accessories and covers to access the timing chain/belt.
  2. Inspect the timing chain/belt for wear, stretching, or damage.
  3. If replacement is needed, align timing marks, remove the old chain/belt, and install the new one according to the manufacturer's specifications.
  4. Reassemble all components and ensure everything is secured.
