Where is the crank shaft seal in a 2001 Tracker?

Answer 1

All engines have two crankshaft seals, one on the vibration dampener end and one on the output end. The seal on the vibration dampener end is called the front seal, the one on the output end is called the rear seal. Crankshaft seals often leak because of pressure buildup inside the crankshaft called "blowby". That usually occurs when the rings have collapsed or excessive carbon has built up inside the ring groove. Collapsed rings can be caused by overheating the engine. Excessive carbon buildup can be caused by failing to change the oil.
