Rear Main Seal for Kia Engine Sealing

DJ Rock RM489 is a premium rear crankshaft seal built to control oil leakage at the rear of the crankshaft where it exits the engine block. It is a direct-fit replacement for select Kia Spectra and Kia Sephia applications, helping maintain proper lubrication and keep oil away from the clutch or flexplate and flywheel area.

Fits 2000-2004 Kia Spectra, rear. Fits 1998-2001 Kia Sephia, rear. This part cross-references MAHLE JV1671 for the same application.

Key Features

• Premium-grade rear main seal for engine sealing service
• Direct-fit replacement for rear crankshaft seal applications

Detailed Description

The DJ Rock RM489 rear main seal is designed for engines that require a reliable seal at the rear crankshaft opening. In the 2000-2004 Kia Spectra and 1998-2001 Kia Sephia, this seal helps maintain crankcase oil control under heat, pressure, and continuous crankshaft rotation. Depending on the original engine design, rear main seals may use different configurations, and this replacement is built for the specified rear application.

Manufactured with durable synthetic rubber or fluoroelastomer sealing materials, the RM489 is made to resist oil breakdown and elevated engine temperatures. The sealing lip design supports consistent contact at the crankshaft surface, which is important for reducing seepage and protecting surrounding drivetrain components. Use RM489 when servicing a leaking rear crankshaft seal on Kia Spectra or Kia Sephia models listed in the fitment data.

What It Helps Fix

• Rear engine oil leaks at the crankshaft exit point
• Oil contamination near the clutch or flywheel area
• Visible oil seepage from the rear main seal area
• Loss of proper engine oil retention
• Seal wear caused by heat, age, and crankshaft rotation

Installation Notes and Tips

Confirm the engine application and rear seal design before installation. Inspect the crankshaft sealing surface for wear, scoring, or contamination, and clean the sealing area thoroughly before fitting the new seal. Proper alignment during installation is important to avoid premature leakage. For Kia Spectra and Kia Sephia rear main seal service, follow the vehicle service procedure for seal depth and orientation.
