The front crankshaft seal is designed to hold engine oil inside the engine where the crankshaft exits at the front. Over time a seal can harden, wear or lose its contact with the shaft. Signs this part may need replacing include oil seepage at the front of the engine or oil residue around the crankshaft pulley area. If a leaking front crank seal is the cause, this engine crankshaft seal kit replaces it. Pinpoint the source of the leak before replacing parts.
