Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, oil catch pan.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting work.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain Oil: Remove the oil drain plug using a socket wrench and allow the old oil to completely drain into a catch pan.
2. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Install the new oil filter, applying a thin layer of oil to the gasket for a proper seal.
3. Refill Oil: Replace the drain plug securely and refill the engine with the manufacturer-recommended oil type and quantity.

3. Adjust Valve Clearance (if necessary)

Sub-steps:
1. Remove Valve Covers: Detach any components obstructing access to the valve covers and remove the covers using a socket set.
2. Measure Valve Clearance: Use a feeler gauge to measure the clearance between the rocker arm and valve stem. Compare with specifications.
3. Adjust Clearance: If adjustments are needed, loosen the adjusting screws and reposition to achieve proper clearance, then retighten.

4. Inspect Timing Belt/Chain

Sub-steps:
1. Remove Timing Cover: Use a socket set to remove the timing cover bolts and gently pry off the cover.
2. Inspect Components: Check the timing belt/chain for wear, tension, and alignment. Look for fraying, cracking, or looseness.
3. Replace if needed: If damaged, replace the timing belt/chain according to manufacturer specifications.

5. Check Exhaust System

Sub-steps:
1. Inspect for Leaks: Visually inspect the exhaust manifold and pipes for cracks or loose connections that could cause ticking.
2. Tighten Connections: Tighten any loose bolts or clamps in the exhaust system.
3. Replace Damaged Parts: If leaks are found, replace any damaged components as necessary.
