Solution

1. Preparation

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

2. Addressing Oil Leaks

Inspect Gaskets and Seals
- Use a socket set to remove components obstructing access to the valve cover and oil pan.
- Check valve cover and oil pan gaskets for signs of wear or damage.
- If damaged, replace with new gaskets.
Replace Gaskets
- Clean the mating surfaces of the gaskets with a gasket scraper.
- Apply a thin layer of gasket maker if required, following manufacturer specifications.
- Reinstall components and torque to manufacturer specifications.

3. PCV System Inspection

Check and Clean PCV Valve
- Locate the PCV valve and remove it from the valve cover.
- Clean the valve with brake cleaner or replace it with a new one if clogged.
- Reinstall the PCV valve ensuring a tight fit.

4. Compression Test

Perform Compression Test
- Remove spark plugs using a socket set.
- Insert the compression gauge into the spark plug hole.
- Crank the engine and note the pressure readings for each cylinder.
- Compare results to manufacturer specifications; if low, consider further engine repairs.

5. Oil Change

Replace Engine Oil
- Drain the old oil using an oil pan and remove the oil filter.
- Install a new oil filter and fill the engine with the recommended fresh oil.
- Start the engine and check for leaks around the oil filter and drain plug.
