Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, compression tester, socket set, torque wrench, oil catch pan, hand tools.
Parts Required: New PCV valve (if faulty), oil filter, engine oil, possibly piston rings or valve seals.

2. Addressing Oil Consumption

A. Replace PCV Valve

Locate the PCV valve on the engine.
Disconnect the vacuum hose from the PCV valve.
Remove the old PCV valve.
Install the new PCV valve and reconnect the hose.
Start the engine and check for any leaks or unusual noises.

B. Perform Compression Test

Remove the spark plugs using a socket set.
Insert the compression tester into the spark plug hole of the first cylinder.
Crank the engine and record the compression reading.
Repeat for each cylinder, comparing results for any significant discrepancies.
If compression is low, further disassembly may be required to inspect piston rings or valve seals.

C. Inspect and Replace Valve Seals (if necessary)

Remove the cylinder head following the manufacturer’s specifications.
Replace the valve seals as needed while the head is off.
Reassemble the cylinder head, ensuring all components are torqued to specifications.

3. Change Engine Oil and Filter

Drain the old engine oil using an oil catch pan.
Replace the oil filter with a new one.
Fill the engine with new oil, using the recommended oil type and quantity.
