Front Crankshaft Oil Seal for Nissan Engines ️

This front engine oil seal sits at the nose of the crankshaft, right behind the crank pulley. Its job is simple but critical: keep pressurized engine oil inside the timing cover area while the crankshaft spins at high RPM. A good seal prevents oil from escaping onto belts, pulleys, and the lower engine bay.

Why this seal is needed

The crankshaft constantly rotates, and without a tight sealing lip, oil will leak out fast. This part maintains proper lubrication inside the engine and helps keep the timing zone clean and dry.

How it works

A flexible rubber sealing lip rides on the crankshaft surface, supported by a tension spring. The outer shell locks into the engine front housing, creating a firm barrier against oil seepage and splash.

What happens if it fails

A worn or hardened seal can cause oil drips, burning-oil smell, belt contamination, and low oil level. If ignored, the engine may run with poor lubrication, increasing wear and risking serious damage.
