Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

Tools Required:

OBD-II scanner
Mechanic's stethoscope
Socket set
Torque wrench
Compression tester

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using jack stands.
2. Remove the oil drain plug and drain the old oil into a suitable container.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and torque to manufacturer specifications (usually around 20-25 Nm).
5. Fill the engine with new oil (consult owner’s manual for correct type and capacity).

3. Inspect and Replace Lifters (if necessary)

Sub-steps:
1. Remove the engine cover by unscrewing bolts.
2. Disconnect any electrical connectors and hoses obstructing access to the lifters.
3. Remove the rocker arms and pushrods carefully.
4. Inspect lifters for wear; replace any that are damaged.
5. Reassemble in reverse order, ensuring to torque bolts to specifications (usually around 20 Nm for rocker arm bolts).

4. Check and Adjust Timing Chain

Sub-steps:
1. Remove the timing chain cover by unscrewing the bolts.
2. Inspect the timing chain for slack or wear.
3. If necessary, replace the timing chain and tensioner.
4. Align timing marks according to manufacturer specifications.
5. Reassemble the cover and torque bolts to specifications (generally around 10 Nm).
