Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, ensure the engine is cool, and disconnect the battery.

2. Inspect and Replace PCV Valve

Locate the PCV valve, which is usually found on the valve cover or connected to the intake manifold.
Remove the PCV valve by twisting it counterclockwise.
Inspect the valve for clogs or debris; clean or replace it if necessary.
Install a new PCV valve by pushing it into place until it clicks.

3. Repair or Replace Engine Seals

Determine if the oil consumption is due to worn seals (valve seals, piston rings).
If valve seals are worn:
- Remove the valve cover.
- Use a valve spring compressor to remove the springs and seals.
- Replace the old seals with new ones and reinstall the springs.
If piston rings are the issue:
- Remove the engine from the vehicle and disassemble the engine to access the pistons.
- Replace the piston rings and reassemble the engine.

4. Refill Engine Oil

After repairs, refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
Replace the oil filter if it was disturbed during repairs.

5. Final System Check

Reconnect the battery and start the engine.
Allow it to warm up while checking for oil leaks around the repaired areas.
