why is my Honda CR-V's engine making a ticking noise?

Solution

1. Preparation

• Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, feeler gauge.
• Safety Warnings: Disconnect the battery before starting work on electrical components.

2. Change Engine Oil and Filter

1. Drain the oil:
   • Place a drain pan under the oil pan.
   • Remove the oil drain plug using a socket set, allowing the old oil to fully drain.
2. Replace the oil filter:
   • Use an oil filter wrench to remove the old filter.
   • Apply a thin layer of new oil on the rubber gasket of the new filter.
   • Install the new filter by hand until snug, then tighten an additional 3/4 turn.
3. Refill with oil:
   • Replace the drain plug and torque to manufacturer specifications.
   • Add new oil through the oil filler cap, using the appropriate type and amount specified in the owner's manual.

3. Adjust Valve Clearance (if applicable)

1. Remove the valve cover:
   • Disconnect any components obstructing access to the valve cover.
   • Remove the bolts securing the valve cover and gently lift it off.
2. Measure and adjust clearance:
   • Use a feeler gauge to measure the clearance between the rocker arm and valve stem.
   • Adjust by loosening the rocker arm lock nut and turning the adjustment screw to achieve the specified clearance.
3. Reinstall the valve cover:
   • Clean the mating surfaces and apply a new gasket if necessary.
   • Reinstall the valve cover and torque the bolts to the manufacturer's specifications.
