Cometic C4815 Rear Main Crankshaft Seal for Toyota 3S-GTE/3S-GT Engine

The Cometic C4815 is a precision-engineered rear main crankshaft seal designed specifically for Toyota 3S-GTE and 3S-GT engines. This critical seal prevents oil leakage at the rear of the crankshaft where it meets the flywheel or flexplate, ensuring proper lubrication system integrity and preventing oil contamination.

Key Features:

• Direct OEM fitment for Toyota 3S-GTE turbocharged and 3S-GT engines
• High-quality construction materials resist heat, oil, and crankshaft wear
• Precision-molded design ensures proper seal compression and longevity
• Essential component for engine rebuilds, rear main seal replacement, or transmission removal service
• Manufactured by Cometic Gasket to strict quality standards

This rear main seal is a critical wear item that should be replaced whenever the transmission or clutch assembly is removed, or when oil leakage is detected at the rear of the engine block. The 3S-GTE engine was used in various Toyota performance models including the MR2 Turbo, Celica GT-Four (All-Trac), and other applications from the late 1980s through the 1990s.
