Engine Crankshaft Seal – Ford (BC3Z-6701-A)

The Engine Crankshaft Seal – Ford (BC3Z-6701-A) is a Genuine OEM engine sealing component designed to prevent oil leakage at the crankshaft interface while allowing smooth and continuous crankshaft rotation. Manufactured by Ford, this crankshaft seal is engineered to original equipment specifications, ensuring precise fitment, proper sealing pressure, and long-term durability consistent with factory engine performance standards.

Constructed from high-quality, oil- and heat-resistant sealing materials, this crankshaft seal is designed to withstand constant rotational contact, engine heat, and prolonged exposure to engine oil without hardening, cracking, or loss of sealing integrity. OEM manufacturing ensures accurate lip geometry and material composition, allowing the seal to maintain consistent contact with the crankshaft surface and deliver reliable leak prevention over extended service intervals.

This component is vehicle-specific and intended for Ford applications requiring part number BC3Z-6701-A. Designed as a direct-fit replacement, the crankshaft seal installs using factory-recommended procedures and tools, with no modification required. Professional technicians benefit from predictable installation during engine or drivetrain service, while experienced DIY mechanics can perform replacement by following factory service guidelines.

Functionally, the crankshaft seal plays a critical role in retaining engine oil within the crankcase while preventing contamination of surrounding components. A worn or damaged seal can lead to oil leaks, reduced lubrication efficiency, and potential damage to belts, pulleys, or drivetrain components. Replacing it with a Genuine Ford OEM crankshaft seal helps restore proper oil control and protect the engine from premature wear.

Key product features and benefits include:

• Genuine Ford OEM engine crankshaft seal

• Oil- and heat-resistant materials for long-term sealing performance

• Designed to match original dimensions and sealing lip characteristics

• Precision-engineered for direct-fit installation using factory specifications

• Suitable for professional engine service or experienced DIY repair

For technicians and vehicle owners who demand factory-correct engine sealing and dependable oil control, the Engine Crankshaft Seal – Ford (BC3Z-6701-A) delivers OEM-quality materials and precise fitment that help ensure leak-free operation and long-term engine reliability.
