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 to prevent any electrical issues while working.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Drain the engine oil using a socket set to remove the oil drain plug.
2. Replace the oil filter using an oil filter wrench.
3. Refill the engine with the manufacturer-recommended oil type and capacity (5W-30 for most F-150 models).
4. Start the engine and check for leaks around the oil filter and drain plug.

Tools Required:

Socket set
Oil filter wrench
Oil catch pan

3. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil packs using a socket set.
2. Unscrew the spark plugs with a spark plug socket and inspect them for wear or damage.
3. Replace with OEM-spec spark plugs (typically Motorcraft SP-534).
4. Reinstall ignition coils and torque to manufacturer specifications.

Tools Required:

Spark plug socket
Torque wrench

4. Inspect and Adjust Valves (if applicable)

Sub-steps:
1. Remove the valve cover using a socket set.
2. Inspect the rocker arms and adjust them as necessary to the manufacturer torque specifications (typically around 20-25 ft-lbs).
3. Replace the valve cover gasket if it shows signs of wear or leaks.
4. Reinstall the valve cover securely.
