Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on the engine.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan.
3. Remove the oil drain plug and allow the old oil to completely drain out.
4. Replace the oil drain plug and torque it to the manufacturer's specifications (typically around 30 ft-lbs for most Toyota models).
5. Remove the old oil filter using an oil filter wrench and install a new oil filter, ensuring to lubricate the rubber gasket with new oil.
6. Fill the engine with the appropriate type and amount of new oil (typically 0W-20 or 5W-20).

3. Inspect Valve Lifters and Timing Components

Sub-steps:
1. Remove the engine cover to access the valve train components.
2. Visually inspect the valve lifters for wear or damage; replace if necessary.
3. Check the timing chain/belt for tension and wear; adjust or replace as needed.
4. Reinstall the engine cover and torque to specifications.

4. Address Exhaust Leaks

Sub-steps:
1. Inspect the exhaust manifold and gaskets for any cracks or leaks.
2. Tighten any loose bolts or replace gaskets as necessary.
3. Test the exhaust system for leaks by running the engine and listening for changes in the ticking noise.
