Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery (negative terminal) for safety.

2. Inspect and Replace Gaskets

Sub-steps:
1. Remove engine covers and components obstructing access to the valve cover.
2. Remove the valve cover bolts using a socket set and lift the valve cover off.
3. Inspect the gasket for wear or damage. Replace if necessary.
4. Clean surfaces with a gasket scraper and ensure they are free of debris.
5. Apply a thin layer of RTV sealant if specified by manufacturer.

3. Replace PCV Valve

Sub-steps:
1. Locate the PCV valve, typically found on the valve cover or intake manifold.
2. Disconnect the hoses connected to the PCV valve.
3. Remove the old PCV valve and replace it with a new one.
4. Reattach the hoses securely.

4. Replace Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using jack stands for access to the oil pan.
2. Place an oil drain pan under the oil pan and remove the drain plug to allow old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and tighten to manufacturer specifications.
5. Fill with the correct type and amount of new engine oil.
