The crankshaft oil seal is located in your car's crankshaft. The crankshaft converts rotational motion into linear motion. This means that it uses the force generated by the pistons in the engine to move in circles so that the car's wheels can turn. The crankshaft is housed in the crankcase, which is the largest cavity in the cylinder block. For the crankshaft to work properly, it must be completely lubricated with oil so that there is no friction. There are two crankshaft seals, one at the front and one at the rear, which are known as front main seals and rear main seals respectively.

Because the crankshaft needs to be lubricated, there are seals at both ends of the crankshaft to prevent oil from leaking. In addition, the seals help prevent debris and contaminants from getting onto the crankshaft itself. In this case, the crankshaft may be damaged or stop working.

The crankshaft seals are made of durable materials so they can withstand the harsh environment of the crankshaft. The materials they are made from may include silicone or rubber. Although they are designed to withstand high pressures and temperatures, they can wear out and become damaged over time.

The front crankshaft oil seal is behind the main pulley. If the seal starts to leak, oil will get on the pulley and get on the belts, steering pump, alternator and everything else that is nearby. The rear oil seal is located along the transmission. The process of replacing the crankshaft rear oil seal is complicated, so it is best to entrust it to a professional mechanic.

Because the crankshaft oil seal can fail over time, it's a good idea to know the symptoms before it fails completely.

Signs that the crankshaft oil seal needs to be replaced include:

• Engine oil leak or oil splashes on the engine
• Oil splashes on the clutch
• The clutch is slipping because oil is splashing onto the clutch.
• Oil leak from under the front crankshaft pulley

The seal is an important part of keeping the crankshaft running smoothly, and the crankshaft is essential for the engine to run properly. Therefore, this repair cannot be delayed.
