Disconnect the battery to avoid any electrical issues during repairs.

2. Identify and Replace Gaskets/Seals

Inspect Gaskets: Remove any engine covers or components blocking access to gaskets.
Remove Old Gaskets: Carefully scrape off old gasket material from surfaces using a gasket scraper.
Clean Surfaces: Use a clean cloth and solvent to ensure surfaces are oil-free.
Install New Gaskets: Apply gasket maker or place a new gasket in the correct position.

3. Replace Oil Filter

Remove Old Filter: Use an oil filter wrench to unscrew the old oil filter. Be prepared for some oil spillage.
Prepare New Filter: Lubricate the rubber O-ring on the new filter with fresh oil.
Install New Filter: Screw on the new oil filter hand-tight.

4. Repair Oil Pan or Drain Plug

Drain Oil: If necessary, drain the oil using an oil catch pan.
Inspect Oil Pan/Drain Plug: Check for cracks or damage; replace if necessary.
Install New Plug or Pan: Replace with new components, tightening to manufacturer specifications.

5. Refill Engine Oil

Add Oil: Using a funnel, pour the correct type and amount of oil into the engine.
