Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.

Tools Required:

Socket set
Torque wrench
OBD-II scanner
Compression tester
Leak-down tester
Oil catch pan

2. Inspect and Repair External Leaks

Sub-steps:
1. Use a socket set to remove engine covers if necessary for better access.
2. Inspect the oil pan, valve cover, and gaskets for signs of leakage.
3. If leaks are found, clean the affected area and replace damaged gaskets or seals.
4. Torque the new gaskets to the manufacturer's specifications.

3. Address Internal Engine Issues

Sub-steps:
1. If compression or leak-down tests indicate poor results, consider an engine rebuild or replacement.
2. If the PCV system is clogged, remove the PCV valve and clean or replace it.
3. Ensure all hoses related to the PCV system are intact and securely attached.

4. Replace Engine Oil

Sub-steps:
1. Drain old oil using an oil catch pan and replace it with the correct type and amount of oil.
2. Replace the oil filter with a new one during the oil change.
3. Run the engine for a few minutes and check for leaks.
