Engine Oil Pan Replacement

What is an oil pan?

The engine oil pan is the main reservoir where the engine oil is held.

How does the oil pan work?

The engine oil pan is located on the bottom of the engine and is large enough to hold all the oil in the engine. It is bolted to the engine block, and to prevent oil leaks there's an oil pan gasket in between the block and pan. The oil pan is where the oil drain plug is located. On all engines there's an oil pick-up located in the pan that's connected to the oil pump. On some engines the pump pickup tube is also located inside the oil pan.

Some engines have an upper and lower oil pan gasket; in these cases, we quote for the lower pan gasket only.

What are the symptoms related to a bad oil pan?

Oil pans don't wear out or break like other parts, they generally only need to be replaced because of external damage from an accident or an improperly tightened drain plug. The main symptom you will experience is an oil leak underneath the engine of your car. The oil that leaks from a damaged oil pan will range from dark brown to dark black. If the leak is large enough or occurs for long enough the oil level will be low enough to turn the oil pressure or low oil level warning light on.

How are oil pan issues diagnosed?

Oil pan issues are very easy to diagnose as the pan is easy to access and view with the naked eye. For scenarios where the oil drain plug is stripped and needs to be addressed, this too is very easy for a mechanic to visually diagnose. In some cases you could have a leak from the oil pan gasket that can be hard to diagnose, especially if the bottom of the engine heavily covered oil, grease and road grime. In these cases in can be helpful for a mechanic to add fluorescent dye to the engine oil, drive the car, then recheck for the source of the leak using a black light.

How is an oil pan replaced?

Some vehicles have a paper gasket, while others may only require an application of sealant according to the manufacturer. Once the pan is installed, the engine oil will be refilled to the correct level and the technician will check for leaks to ensure a proper repair.
