What is an oil pan and how does it work?

An oil pan is a reservoir attached to the bottom of your engine to store the oil that lubricates all of the moving parts inside the engine. Engine oil, also known as “motor oil”, is circulated throughout an engine by the oil pump when the engine is running. It also flows through a filter that removes contaminants that can be harmful and cause premature wear to engine components. Beyond lubrication of those components, the oil also serves to clean them and keep them cool. The oil begins its journey in the oil pan. Made of steel or aluminum, a typical oil pan holds anywhere from four to six quarts of engine oil, depending on the vehicle make and model. How much oil is in your engine - the oil level - can be checked by removing a dipstick that extends into the oil pan from the engine compartment. A drain plug on the bottom of the oil pan allows old oil to be drained out when it is time for fresh oil to be installed. The oil pan is affixed to a flange on the bottom of the engine block and is sealed with a gasket.

How can I tell if my engine needs a new oil pan?

Oil pans usually need to be replaced for one of two reasons

collision or corrosion. If an oil pan is impacted by debris on the road (or off of the road), or if the metal that makes up the oil pan is rusted sufficiently that it no longer holds oil, it will need to be replaced. The location of an oil pan is close to the ground, making it difficult to see unless your vehicle is lifted in the air. While it is possible to detect damage to an oil pan through a quick inspection, it is more likely that you will notice a fluid leak on the ground after your vehicle has been in one place for a while. Of course, a mechanic can lift your car and take a look to verify a damaged oil pan.

How is this service performed

How is a Oil Pan Replacement done?

To replace the oil pan on your engine, a technician must first lift and support your vehicle off of the ground for access to the bottom of the engine where the pan is located. On some vehicles, an engine crossmember (part of the lower structure of the body or frame) must be removed as well. On others, steering, exhaust, or other components may also need to be removed. And in some cases, the engine may need to be shifted out of position to get at all of the oil pan fasteners or to create space for the pan to be dislodged. In general, however, once access is gained, steps to remove and install an oil pan include the following

  • Drain the old oil from the engine
  • Remove the fasteners that hold the pan to the engine (there are many)
  • Carefully pry the oil pan from its mounting flange
  • Extract the pan from its mounting location
  • Clean any gasket/seal residue from the mounting flange on the engine
  • Insert the new oil pan into place along with a new gasket
  • Start all of the fasteners by hand
  • Torque all fasteners to manufacturer’s specifications in the correct sequence
  • Install fresh oil (and probably an oil filter)

OTHER QUESTIONS CUSTOMERS ASK

Is replacing an oil pan easy?
The level of difficulty when replacing an oil pan depends entirely on the make and model of your vehicle. The repair always requires that your vehicle be safely lifted and supported in the air for access. There are also many fasteners to remove and reinstall. But the real difficulty comes if a number of components must be removed for access, or if the engine (or engine mounts and crossmember) must be moved to create enough clearance for the pan to be removed.
Can you seal a leaking oil pan?
Whether or not you can seal a leaking oil pan depends on where the leak is coming from. If the oil leak is due to a bad oil pan gasket or seal, then yes. You can reseal the pan by removing it and installing a fresh gasket or sealant. If, on the other hand, you are referring to “sealing” a crack, hole, or corroded spot on your oil pan, then no. Sealing up a hole from the outside is no guarantee that you will keep the oil inside your engine and is not recommended.
Can you drive a car with a cracked oil pan?
It may be possible to drive a car with a cracked oil pan, but not for long. If the oil level drops, not only will it tend to break down (degrade) faster, it will not be able to provide sufficient lubrication to your engine. If the leak is subtle, frequent checks of the oil level on the dipstick might help. Make sure that the oil level remains in the zone between “full” and “low” to preserve your engine. But if the leak is significant, serious engine damage can occur from lack of lubrication.
