Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, oil catch pan
Let the engine cool down and disconnect the battery to prevent electrical shorts.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and allow old oil to drain into the catch pan.
2. Replace the drain plug and torque to manufacturer's specifications (usually around 25 Nm).
3. Remove the oil filter using an oil filter wrench.
4. Lubricate the rubber O-ring on the new oil filter with fresh oil and install it.
5. Refill the engine with the recommended oil type (check owner's manual for specifications).

3. Inspect Rocker Arms and Lifters

Sub-steps:
1. Remove the engine cover using a socket set.
2. Visually inspect the rocker arms and lifters for wear or damage.
3. If any components are worn, replace them individually or as a set, ensuring to torque to specifications.

4. Check Timing Belt/Chain

Sub-steps:
1. Remove the timing cover using a socket set.
2. Inspect the timing belt/chain for signs of wear, such as cracks or fraying.
3. If necessary, replace the timing belt/chain, ensuring to align timing marks correctly during installation.
