If you're experiencing an oil leak in your 2007 Honda Pilot, it may be time to replace the oil pan. The oil pan is located at the bottom of the engine and holds the engine oil. While it rarely needs to be replaced, external damage from an accident or an improperly tightened drain plug can cause an oil leak and require a new oil pan. Replacement costs can range from $497 to $556, but if you're handy and experienced, you may be able to tackle this job yourself. It typically takes a technician around 4 hours to replace an oil pan, and special tools may be required if the access to the oil pan bolts is difficult.

What You'll Learn
Diagnosing oil pan issues
Visible Damage to the Oil Pan
Impact damage from driving over low-lying parts of the road or debris can cause puncture or rust spots in the oil pan. This can lead to leaks, which may start as small drips and gradually worsen over time. Visible damage to the oil pan is a clear indicator that it needs to be replaced before any leakage occurs.
Oil Puddles or Stains Under the Car
Oil puddles or stains under your vehicle are a common sign of an oil leak. These leaks can start small but can worsen and cause significant damage to the engine if left unattended. It is essential to address oil leaks promptly to avoid serious issues.
Leaks Around the Oil Drain Plug
The oil drain plug helps hold the oil in and is removed during oil changes. Over time, this plug can become damaged and may start to leak. The plug contains a crush-type gasket that can fail or become damaged, leading to leaks. If the threads of the oil drain plug are stripped, it may take some time to notice the leak. In this case, the only fix is to replace the oil pan.
Illuminated Oil Light
If you notice the low oil level warning light on your dashboard, it could indicate a potential oil leak. A quick dipstick test can help confirm whether the oil level is low, especially if you recently changed the oil.
Smoke or Burning Oil Smell from the Engine
An oil pan gasket leak may allow engine oil to drip onto the heated exhaust manifold and pipe, causing it to burn and release smoke. Additionally, a strong odour of burning oil is a good indicator that your car is leaking oil.
Engine Overheating
If your engine has lost a significant amount of oil, it can lead to overheating due to inadequate lubrication. Ignoring this issue can result in irreversible engine damage.
Other Potential Issues
While not directly related to the oil pan, other factors can contribute to oil leaks. These include a worn camshaft seal, damaged head gasket, incorrectly installed oil filter, or a damaged valve cover gasket. Therefore, it is essential to correctly diagnose the source of the leak before attempting any repairs.

Removing the oil pan
To remove the oil pan from your 2007 Honda Pilot, you will first need to drain the oil. This is because the oil pan is the main reservoir where the engine oil is held. Once the oil is drained, you can begin to remove the oil pan itself.
The oil pan is bolted to the engine block, so you will need to remove these bolts. There should be 18 bolt holes. Before removing the bolts, it may be necessary to raise the vehicle or remove the front subframe to access the oil pan bolts.
Once the bolts are removed, carefully take out the oil pan. Be cautious of any remaining oil in the pan and be prepared to catch it with a container. It is also important to note that the oil pan gasket, located between the engine block and the oil pan, may be difficult to remove and may require a mechanic's assistance.
After the oil pan is removed, the mating surfaces on both the engine block and the oil pan should be cleaned, and a new gasket should be applied. Some vehicles may require an application of sealant instead of a new gasket, according to the manufacturer's recommendations.
In addition, whenever the oil pan is removed, it is recommended to have the oil pump pickup screen checked for debris and cleaned if necessary. It is also important to ensure that the oil pan drain plug threads are not damaged, as this can cause oil leaks. If the threads are damaged, they can be repaired or replaced by a repair shop.

Cleaning and replacing the gasket
To clean the oil pan gasket surface, you'll want to use a non-metal tool to scrape away the old gasket. A plastic razor blade or a plastic/composite scraper are good options. You can also use a bristle disc attached to a rotary tool, but be careful not to use too much force as it can damage the surface. After most of the gasket is removed, you can use a corner of the scraper to get the remaining bits. Make sure to clean the surface with a detergent that breaks down oil (like Simple Green) and a mild abrasive pad. Just be sure to avoid the area where the oil gasket sits, as you don't want to create an uneven surface. Finally, wipe down the surface with a clean cloth and either brake cleaner, lacquer thinner, or acetone to remove any residual oil.
When replacing the gasket, it's important to use a new gasket that is designed for your specific vehicle. You can use a paper gasket, or you may need to apply a sealant according to the manufacturer's instructions. Make sure to follow the torque specifications for the oil pan bolts, as over-tightening can cause the oil pan to warp and leak.

Refilling the engine oil
Once the oil pan has been replaced, the next step is to refill the engine oil. This is a crucial step to ensure the engine has enough lubrication and does not sustain any damage. The 2007 Honda Pilot's engine oil capacity with a filter is 4.5 quarts (4.3 litres). It is important to use the correct type of oil for your car. The 2007 Honda Pilot takes SAE 5W-20 engine oil, which is synthetic. This type of oil has a thinner viscosity, creating minimal friction and improving fuel economy.
To refill the engine oil, first, locate the oil filler cap on the engine. This is usually a yellow or black cap with a symbol of an oil can marked on it. Remove the cap by turning it counterclockwise. Next, using a funnel, pour in the recommended amount and type of oil. It is important to pour slowly and carefully to avoid any spills or overfilling. Once you have added the correct amount of oil, replace the oil filler cap by turning it clockwise until it is tight.
After refilling the engine oil, it is important to check the oil level to ensure it is correct. This can be done by using the dipstick, which is usually located near the oil filler cap. Remove the dipstick, wipe it clean with a cloth or paper towel, then reinsert it fully and remove it again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick. If the level is too low, add more oil, and if it is too high, absorb the excess with a cloth or absorbent material.
Finally, start the engine and check for any leaks. Let the engine run for a few minutes, then turn it off and check the oil level again with the dipstick. Ensure that the oil level is correct and that there are no leaks. If there are no issues, your Honda Pilot's engine oil has been successfully refilled and you are good to go!
