The crankshaft oil seal prevents engine oil from leaking out of the engine system. The engine oil is needed to lubricate the various engine components. Without oil, the moving parts would not be lubricated. This would cause friction between the engine parts, ultimately leading to serious engine damage. The crankshaft oil seal is located at the crankshaft housing. A pulley is mounted on the crankshaft, which drives various components such as the water pump, alternator, and oil pump. The operation of the crankshaft is therefore important for the operation of the lubrication system and vice versa. The crankshaft oil seal prevents engine oil from leaking out of the system and ensures that the parts remain properly lubricated. This seal can wear out over time. Below we explain the symptoms of a worn crankshaft oil seal.
Crankshaft oil seal defect
Due to the heat of the engine and moving parts, the crankshaft oil seal can become defective after some time. The car's engine expands due to the heat. Seals must therefore be able to withstand this heat and movement. However, cracks can eventually develop in the seal. Ultimately, this part can become so worn that a leak occurs. There are a number of symptoms by which you can recognise a defective crankshaft oil seal:
- Oil is leaking from the crankshaft housing.
- The clutch is slipping: this is because oil is leaking onto the clutch plate.
- The car's engine is overheating: there is not enough engine oil to lubricate and cool the parts.
Replacing the crankshaft oil seal
Replacing the crankshaft oil seal is a difficult job. If you have some knowledge of car maintenance, you can replace this part yourself. Note that the exact way to replace the seal may vary depending on the make and model of the car. Make sure you jack the car up with a car jack and keep it stable with axle stands. Various car parts will need to be disassembled, such as the timing belt and crankshaft seal. We recommend checking the timing belt directly for defects and replacing it immediately if it is defective. This will save you a lot of effort and time.
Would you prefer to have a specialist replace the crankshaft oil seal? Then simply order the seal from Winparts and take it to the garage yourself. The prices for car parts are often slightly higher at the garage than online. Therefore, it is usually cheaper to buy the parts online. Then you only have to pay the installation costs.
