Important Compatibility Information
Different seal designs may be installed depending on the vehicle and production version.
On some first-generation vehicles, such as the BMW 1 Series F20 114d, the crankshaft oil seal could still be replaced separately. On most later versions, the oil seal is not available as an individual replacement part, and the complete timing case cover must be replaced.
For replacing the earlier seal design, use Item no. 116622.
Recommended Additional Tool
We recommend using flywheel holding tool Item no. 118126, as BMW 116130, to securely lock the crankshaft during the repair.
