Tools Required: Oil filter wrench, oil pan, socket set, funnel.
Safety Warnings: Ensure the engine is cool before draining oil to avoid burns.

3. Inspect and Replace Valvetrain Components

Sub-steps:
1. Remove the engine cover to access the valvetrain.
2. Inspect lifters and rocker arms for wear; replace any damaged components.
3. Reassemble components ensuring all bolts are torqued to specifications.
Tools Required: Socket set, torque wrench, screwdriver set.
Safety Warnings: Use gloves and eye protection when working with engine components.

4. Check for Exhaust Leaks

Sub-steps:
1. Inspect exhaust manifold and connections for signs of leaks.
2. Tighten any loose bolts or replace gaskets as needed.
3. Perform a leak test using a smoke machine if necessary.
Tools Required: Wrench set, smoke machine (optional).
Safety Warnings: Ensure the exhaust system has cooled before inspection.
