Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the drain plug using a socket set and allow the old oil to drain completely into a container.
2. Replace the oil filter using an oil filter wrench, ensuring to lubricate the rubber O-ring on the new filter with fresh oil before installation.
3. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 20 lb-ft).
4. Fill the engine with the recommended oil type (typically a synthetic 5W-30 for the G70) using a funnel.
5. Start the engine and allow it to run for a few minutes, checking for leaks around the oil filter and drain plug.

3. Inspect and Adjust Engine Components

Sub-steps:
1. Remove the valve cover to access the valvetrain.
2. Inspect for any signs of wear on the rocker arms, push rods, and lifters.
3. Adjust the valve clearance if applicable or replace worn components.
4. If the timing chain or belt is accessible, check for proper tension and alignment, replacing if necessary.

4. Reassemble and Test

Sub-steps:
1. Reinstall the valve cover using a new gasket if necessary and torque the bolts to the specified value.
2. Reconnect the battery and start the engine.
3. Listen for any remaining ticking noises and observe engine performance.
