A. Oil Filter Replacement

Sub-steps:
1. Place an oil drain pan under the oil filter.
2. Use an oil filter wrench to remove the old oil filter.
3. Apply a thin layer of clean oil to the rubber gasket of the new filter.
4. Install the new oil filter by hand until snug, then tighten slightly more (do not over-torque).

B. Oil Pan Gasket Replacement

Sub-steps:
1. Drain the engine oil into the pan.
2. Remove the bolts securing the oil pan using a socket set.
3. Carefully separate the oil pan from the engine block.
4. Clean the mating surfaces with a gasket scraper.
5. Apply a new gasket or gasket maker as per manufacturer specifications.
6. Reinstall the oil pan and torque bolts to the manufacturer’s specified torque.

C. Valve Cover Gasket Replacement

Sub-steps:
1. Remove any components obstructing access to the valve cover (e.g., intake hoses).
2. Remove the valve cover bolts using a socket set.
3. Carefully lift the valve cover off and replace the gasket.
4. Clean the mating surfaces, apply new gasket, and reassemble the valve cover with the correct torque.

4. Refill Engine Oil

Refill the engine oil using the appropriate type and amount specified in the owner’s manual.
