Solution

1. Preparation

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

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine, usually near the valve cover.
Remove the old PCV valve from its housing.
Inspect the valve for blockage or damage; replace if necessary.
Install the new PCV valve, ensuring it is securely fitted.

3. Address Oil Leaks

Clean the area around the suspected leak with engine degreaser.
Tighten any loose bolts on the oil pan or gaskets.
If leaking persists, replace the oil pan gasket or valve cover gasket as needed.
Use a torque wrench to tighten gaskets to the manufacturer’s specifications.

4. Compression Test

Remove the spark plugs to facilitate the compression test.
Insert the compression gauge into the spark plug holes.
Crank the engine and record the compression readings for each cylinder.
Compare the readings to manufacturer specifications; if low, further investigation into piston rings or valve seals may be required.

5. Clean the Intake System

Remove the air intake duct to access the throttle body.
Clean the throttle body and intake manifold using an appropriate cleaner.
Check for oil accumulation in the intake; if excessive, further inspection of the engine's internal components may be necessary.
