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

2. Address External Oil Leaks

Sub-steps:
1. Clean the engine surface using an engine degreaser to identify leaks.
2. Inspect oil filter and replace if damaged.
3. Replace any worn or damaged gaskets and seals.
Tools Required: Wrench set, engine degreaser, oil filter wrench, torque wrench.

3. Repair or Replace the PCV System

Sub-steps:
1. Locate the PCV valve and remove it from the engine.
2. Inspect the valve for clogs or damage; clean or replace as necessary.
3. Check the hoses connected to the PCV system for blockages and replace if needed.
Tools Required: Pliers, socket set.

4. Perform Engine Repair for Internal Issues

Sub-steps:
1. If compression test shows low compression, consider replacing piston rings or valve seals.
2. Remove the engine head if valve seals are suspect; replace seals and reassemble.
3. Reassemble the engine, ensuring all bolts are properly torqued to manufacturer specifications.
Tools Required: Torque wrench, socket set, engine hoist (if necessary).
