1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Repair Oil Leaks

Sub-steps:
1. Use a socket set to remove any components obstructing access to the oil filter or pan.
2. Clean the area around the oil pan and filter to identify the source of leaks.
3. Replace any damaged gaskets or seals, such as the valve cover gasket or oil pan gasket.
4. Reinstall components and ensure all bolts are torqued to manufacturer specifications.

3. Replace Worn Components

Sub-steps:
1. If compression test indicates low pressure, consider replacing piston rings or valve seals.
2. Remove the cylinder head if necessary, following specific torque values for reinstallation.
3. Install new piston rings or valve seals as needed, ensuring proper lubrication.
4. Reassemble the engine components and torque to specifications.

4. Clean or Replace PCV System

Sub-steps:
1. Locate the PCV valve and remove it from the engine.
