The crankshaft seal is a small but vital component in your car’s engine. A faulty crankshaft seal can lead to oil leaks and subsequently to severe engine damage. Therefore, timely replacement is essential. This article explains everything you need to know about replacing the crankshaft seal.
What Does “Replacing a Crankshaft Seal” Mean?
“Replacing a crankshaft seal” means replacing the old, faulty seal on the crankshaft with a new one. This seal prevents oil from leaking out of the engine. From a technical standpoint, the crankshaft seal is a lip seal located between the crankshaft and the engine block. An intact crankshaft seal is essential for the engine’s smooth operation. From an economic standpoint, timely replacement of the crankshaft seal can prevent expensive engine damage. “If the crankshaft seal is not replaced in time, it can lead to catastrophic engine failure,” says renowned US automotive mechanic Paul Stevenson in his book “Automotive Troubleshooting.”
Crankshaft Seal: Definition and Function
The crankshaft seal is a seal that prevents engine oil from leaking out. It is located on the crankshaft, the central drive shaft in the engine. The rotation of the crankshaft creates pressure differences that the seal must compensate for. A leaky crankshaft seal leads to oil leaks and can ultimately damage the engine.
Why Does the Crankshaft Seal Need to Be Replaced?
A faulty crankshaft seal leads to oil leaks. This oil loss can cause lubrication problems in the engine and ultimately lead to engine damage. Signs of a faulty crankshaft seal include oil spots under the car and a dropping oil level. Sometimes a burning oil smell can also be noticed.
How to Replace the Crankshaft Seal
Replacing the crankshaft seal is a complex task that is best performed by a qualified repair shop. Depending on the vehicle model, various components must be disassembled to access the crankshaft seal. Special tools are often required.
