The engine crankcase in you car is filled with oil to keep everything lubricated, and to keep the oil inside of the engine, seals are used anywhere there is a seam in the engine, or any place a shaft protrudes from the engine. One such seal is the front main crankshaft seal. This seal is located around the the crankshaft at the front of the engine, and keeps oil from leaking out around the crankshaft. Unfortunately, over time seals will become brittle, crack and begin to leak due to their exposure to heat and oil.

90x110x12mm - usually replaced when servicing the timing chains The front seal or crankshaft seal is one of the most difficult to replace. However, they often fail, and when they do, your car will be marking it's territory with little oil drops wherever you park. Apart from making a mess, it can also cause oil to come in contact with the pulley surfaces. Replace yours and keep your oil in your engine. The perfect time to replace this seal is when you are doing a timing replacement. You already have everything apart, so you might as well add this piece even if it hasn't failed yet as a bit of preventative maintenance.
