Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, coolant pressure tester.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Repair Oil Leaks

Sub-steps:
- Visually inspect the valve cover and oil pan gaskets for leaks.
- If leaks are found, remove the old gasket using a scraper.
- Clean the mating surfaces with a solvent.
- Apply a new gasket or sealant as per manufacturer specifications and torque down to the recommended values.

3. Address Coolant Leaks

Sub-steps:
- Use a coolant pressure tester to check for leaks in the cooling system.
- If leaks are identified, replace any faulty hoses, clamps, or the radiator.
- Refill the cooling system with the appropriate coolant type.

4. Replace Spark Plugs

Sub-steps:
- Remove the ignition coils using a socket set.
- Extract the spark plugs with a spark plug socket.
- Inspect spark plugs for signs of carbon buildup or oil contamination.
- Install new spark plugs, ensuring they are gapped correctly and torqued to specifications.

5. Compression Test

Sub-steps:
- Remove spark plugs and insert the compression tester into the cylinder.
- Crank the engine to take compression readings.
- Compare results to manufacturer specifications; if compression is low, further engine disassembly may be necessary.
