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 before working on electrical components.

2. Inspect and Repair Oil Leaks

Sub-steps:
1. Clean the engine surface to locate the source of the leak.
2. Replace any worn or damaged gaskets (e.g., valve cover gasket, oil pan gasket).
3. Tighten any loose bolts or fittings that may be contributing to the leak.
Tools required: Wrench set, gasket scraper, RTV sealant (if needed).

3. Replace PCV Valve (if faulty)

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

4. Engine Oil Change

Sub-steps:
1. Drain the old oil using a drain pan.
2. Replace the oil filter with a new one.
3. Refill the engine with the recommended oil type and capacity.
Tools required: Oil filter wrench, drain pan, funnel.

5. Perform Engine Compression Test (if necessary)

Sub-steps:
1. Remove spark plugs for access.
2. Insert compression tester into each cylinder and crank the engine.
3. Record the compression readings; compare to manufacturer specifications.
Tools required: Compression tester.
