Crankcase pans

The sump pan or crankcase pan is located underneath the engine block; it is the collection container for all the oil in the engine block. When the engine is switched off, all the oil collects in it. Almost every combustion engine is equipped with a sump pan and this is called a ‘wet-sump' lubrication system. The oil pump removes the oil from the lowest point of the sump pan to provide the engine block with oil pressure and thus lubrication. Some more exclusive sports cars have a so-called 'dry-sump' lubrication system with no sump pan installed. One of the reasons for this is the limited installation space and the G-forces in these sports cars, which could cause the oil pressure to drop with the previously mentioned 'wet-sump' lubrication system.

When a crankcase pan is defective, it is always due to damage. This could be due to driving over objects, causing the crankcase pan to leak. After all, the crankcase pan is mounted on the underside of the car and is often the car’s lowest point. The crankcase pan is sealed with a gasket on the underside of the engine block. Over time, many cars fall victim to a leaking crankcase pan because this seal fails.
