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 to ensure safety during repairs.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine.
Remove the PCV valve by gently twisting it out of its socket.
Inspect the valve for clogs; if dirty, replace with a new valve.
Reinstall the new PCV valve firmly in place.

3. Perform Engine Compression Test

Remove spark plugs using a spark plug socket.
Insert the compression tester into each cylinder and crank the engine.
Record the compression readings; compare them to manufacturer specifications.
If readings are low, consider further investigation into piston rings or cylinder walls.

4. Check for Oil Leaks

Clean the engine surface with a degreaser to identify oil leaks.
Use a UV dye added to the oil and a UV light to trace any leaks systematically.
Repair or replace any faulty gaskets or seals as identified.

5. Oil Change

Drain the engine oil using an oil pan.
Replace the oil filter with a new one.
Refill the engine with the correct type and amount of oil as specified in the owner's manual.
