Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery before starting work.

2. Inspect and Replace Gaskets

Tools Required: Socket set, torque wrench, gasket scraper.
Remove engine covers if necessary to access the gaskets.
Inspect valve cover gaskets and oil pan gaskets for wear or leaks.
If damaged, clean the surfaces where the gaskets sit and replace with new gaskets.
Torque the gaskets to the manufacturer specifications (refer to service manual).

3. Replace PCV Valve

Tools Required: Pliers, socket set.
Locate the PCV valve, which is usually found on the valve cover.
Remove the old PCV valve (may require twisting to free it).
Install a new PCV valve, ensuring it fits snugly in its housing.
Check all hoses connected to the PCV system for cracks or blockages and replace as necessary.

4. Conduct Oil Change

Tools Required: Oil filter wrench, oil catch pan, funnel.
Drain the old oil using an oil catch pan.
Replace the oil filter with a new one.
Refill the engine with the manufacturer-recommended oil type and quantity (typically 0W-20 for XV70).
Run the engine for a few minutes and check for leaks.
