Essential Component: Rear Crankshaft Oil Seal

The rear crankshaft oil seal is a crucial component that ensures the smooth operation of any automobile's engine. It's designed to prevent oil from leaking out between the crankshaft and the engine block. This is necessary to maintain optimal oil levels and prevent potential engine damage caused by insufficient lubrication.

How It Works

Positioned at the back of the engine, the rear crankshaft oil seal (often made of high-quality rubber or silicone) fits snugly around the crankshaft to form a tight seal. This prevents engine oil from seeping out as the crankshaft rotates, thereby safeguarding engine efficiency and performance.

Risks of a Broken Seal

When the rear crankshaft oil seal fails, the consequences can be costly. An oil leak might develop, leading to decreased oil levels, which can result in inadequate lubrication. Over time, this can cause engine components to wear prematurely or even lead to a complete engine failure. Furthermore, oil leaks pose a fire hazard and can result in environmental damage due to oil seepage.

Compatibility

This rear crankshaft oil seal is compatible with the following Nissan models:

• M45
• Fx35/45
• M35/45
• Qx70/Fx
