Mazda 6 Crankshaft Seal

The main task of the Mazda 6 Crankshaft Seal is to prevent the leakage of engine oil at the crankshaft opening at the end of the block and to retain lubrication at its proper location. This circular part is made of a combination of hardened metal and soft rubber, is positioned at the front of the engine, and forms a tight seal that traps oil within the crankcase, limiting friction on the rotating components and preventing untidy spills that would reduce the oil level and increase wear and tear. In the broader Mazda range, the design has been essentially the same since this simple arrangement already balances strength with elasticity, but more recent cars may employ more modern rubber compounds to allow longer life, yet older models of the range use more traditional materials. No matter what the year, the Crankshaft Seal works in a similar manner, that is, it is clamped around the shaft, preventing pressurized oil from leaking out. Before drivers notice puddles on the driveway or the smell of oil after a trip, they usually first see dark spots on the driveway or detect an oily odor, which are evidence that the seal lip has solidified or split due to mileage and heat. Otherwise, the leak may cause the loss of oil in sufficient amounts to starve bearings, and thus repairing a worn Crankshaft Seal at the first indications of leakage spares the cost of larger repairs. Owners of Mazda are happy that this small seal keeps the lubrication system of the whole car safe and secure in silence, yet plays a significant role in protecting the engine of every Mazda 6.
