OEM 1999-2002 Nissan Skyline R34 Front Main Seal for RB20DE, RB25DE, and RB25DET equipped models. 

This is the Front Main Seal, otherwise known as the Front Crankshaft Seal. When this seal starts to fail, it will leak oil onto the pulleys which will then get on the belt and cause it to slip. It is best to replace this seal whenever performing any work under the timing cover.
