3. Tighten any loose bolts or replace gaskets as needed.
Tools Required: Socket set and torque wrench.

3. Repairing Internal Oil Consumption

Sub-steps:
1. If compression tests indicate low compression, remove the cylinder head.
2. Replace worn piston rings and valve seals as necessary.
3. Reassemble the engine and torque all bolts to manufacturer specifications.
Tools Required: Torque wrench and socket set.

4. PCV Valve Replacement

Sub-steps:
1. Locate the PCV valve on the engine.
2. Disconnect the hose and remove the old valve.
3. Install the new PCV valve and reconnect the hose.
Tools Required: Pliers and socket set.
