Core Product Description
The 21440-2F060 Hyundai Kia Oil Seal Case Assembly is a rear crankshaft oil seal component for select Hyundai and Kia diesel engine applications. Also known as a rear oil seal case or crankshaft rear seal, this component is positioned at the rear of the engine, where the crankshaft exits the engine block, to prevent engine oil from leaking out and to keep contaminants from entering the engine .
This component serves as a critical barrier in the engine’s oil circulation system, ensuring oil remains within the designated pathways to properly lubricate moving parts. When this seal fails, oil leaks can occur, leading to low oil levels and potential internal engine damage if not addressed promptly .
This part is a direct replacement component designed for specific Hyundai and Kia diesel models.
When Should You Replace It?
Consider replacing your oil seal case assembly if you experience any of the following symptoms:
-
Oil leaks visible between the engine and transmission bell housing
-
Burning oil smell coming from the engine area
-
Low engine oil level without visible external leaks elsewhere
-
Oil spots on the driveway or garage floor
-
Clutch slipping (on manual transmission models) caused by oil contamination
-
Visible damage or deterioration to the oil seal or housing
-
You are performing an engine rebuild or transmission service that requires removal
Note: The oil seal case is a critical sealing component that should be inspected during engine or transmission service and replaced when signs of wear or damage appear. Replacing the seal and case together is recommended for reliable sealing performance.
