how to fix Honda Civic 10th Generation (2016-2021) oil leak

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Drain Engine Oil

• Place a drain pan under the oil pan.
• Remove the oil drain plug using a socket wrench.
• Allow the oil to drain completely into the pan.
• Replace the drain plug and tighten it to the manufacturer's torque specifications (usually around 20-25 ft-lbs).

3. Replace the Oil Filter

• Using an oil filter wrench, remove the old oil filter.
• Lubricate the rubber O-ring of the new oil filter with a little fresh oil.
• Install the new oil filter by hand, tightening until snug (do not overtighten).

4. Inspect and Replace Gaskets/Seals

• If the valve cover gasket is leaking, remove the valve cover by loosening the bolts (consult service manual for torque specs).
• Remove the old gasket and clean the mating surfaces.
• Install a new valve cover gasket and reattach the valve cover.
• If the crankshaft seals are leaking, remove any necessary components to access the seals, replace them, and reassemble.

5. Clean Up and Refill Oil

• Clean any residual oil from the engine and surrounding areas with a degreaser.
• Refill the engine with the appropriate type and amount of oil (typically 0W-20 for Honda Civics).
• Start the engine and let it run for a few minutes, then check for leaks.
