What It Helps Address

• Engine oil leakage at the crankshaft seal area
• Contamination entering the sealed engine interface
• Loss of sealing contact from worn or hardened seal material
• Service issues caused by incorrect bore or outside diameter sizing
• Noise or drivability concerns related to oil contamination around the front or rear seal location

Installation Notes and Tips

• Verify the year, make, model, and position before ordering; this part is listed for front, rear, and N/A positions depending on application.
• Inspect the crankshaft sealing surface for wear, scoring, or contamination before installation.
• Clean the housing and shaft area thoroughly so the seal seats evenly.
• Confirm the seal dimensions match the original part: 1.987 in. bore diameter, 2.000 in. outside diameter, and 1.437 in. width.
• Use the vehicle notes where provided, such as DOHC, SOHC, diesel, or production-date restrictions.
