Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery before starting any work to avoid electrical issues.

2. Check Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick, remove it again, and check the oil level.
If low, add the manufacturer-recommended oil type (usually 0W-20 for most Toyota engines).

3. Inspect Exhaust Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the exhaust manifold and pipes for cracks or loose connections.
Tighten any loose bolts and replace damaged gaskets as necessary.

4. Examine Valve Cover

Remove the valve cover bolts using a socket set.
Lift the valve cover off and inspect the gasket and mating surface for wear.
Replace the valve cover gasket if it shows signs of wear or damage.

5. Check Drive Belts and Pulleys

Inspect the drive belts for fraying, cracking, or excessive wear.
Check the tension of the belts and adjust or replace them if necessary.
Inspect the pulleys for smooth operation and replace any that are worn or misaligned.
