Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before starting work.

2. Change Engine Oil and Filter

Sub-step 1: Place the vehicle on a level surface and lift it using a jack and jack stands.
Sub-step 2: Remove the oil drain plug with a wrench and drain the old oil into a suitable container.
Sub-step 3: Replace the oil filter using an oil filter wrench; lubricate the new filter's rubber gasket with fresh oil before installation.
Sub-step 4: Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 25-30 ft-lbs).

3. Inspect Valve Train Components

Sub-step 1: Remove the valve cover by unscrewing the bolts; ensure to keep track of the order and placement of the bolts.
Sub-step 2: Visually inspect the rocker arms, pushrods, and lifters for wear, damage, or improper clearance.
Sub-step 3: Adjust valve clearances if necessary, based on manufacturer specifications using a feeler gauge.
Sub-step 4: Reinstall the valve cover with a new gasket to prevent leaks.

4. Inspect and Replace Timing Belt/Chain (if necessary)

Sub-step 1: Remove components obstructing access to the timing belt/chain, such as the front engine cover.
Sub-step 2: Check the timing belt/chain for wear and proper tension; replace if frayed or loose.
Sub-step 3: Reinstall any removed components and ensure proper alignment of timing marks.
