⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before removing any components to prevent burns.

Symptoms

•Oil spots or puddles under the vehicle
•Low oil pressure warning light illuminated
•Engine oil level dropping quickly
•Burning oil smell while driving
•Engine noise due to insufficient lubrication

Diagnostic Steps

1
Inspect the ground under the vehicle for oil spots and determine their location.

Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Identify the Source of the Leak

Clean the area around suspected leak points with engine degreaser.
Start the engine and let it run for a few minutes while observing for oil seeping out.
Use a UV dye if necessary to help identify the leak source.

3. Repair or Replace Affected Components

Oil Filter Replacement:
- Use an oil filter wrench to remove the old filter.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new filter hand-tight, then tighten it an additional ¾ turn.
Oil Pan Gasket Replacement:
- Drain the engine oil by removing the drain plug.
- Remove the oil pan bolts and gently pry off the oil pan.
- Clean the mating surfaces of the oil pan and engine block.
- Apply a new gasket or gasket maker according to specifications.
- Reinstall the oil pan and torque the bolts to manufacturer specifications (typically around 8-10 ft-lbs).
Valve Cover Gasket Replacement:
- Remove any components obstructing access to the valve cover (e.g., air intake).
- Remove the bolts securing the valve cover and lift it off.
- Clean the surface and apply a new gasket.
- Reinstall the valve cover and torque bolts to manufacturer specifications (usually around 7-9 ft-lbs).

4. Refill Engine Oil

Replace the drain plug and refill the engine with the appropriate type and amount of oil (usually 5W-20 for Honda Pilot).
Start the engine and allow it to run for a few minutes, checking for leaks.
