Keep engine oil where it belongs — sealing the point where the back of the crankshaft exits the block — with the MAHLE Engine Crankshaft Seal 67766. This rear crankshaft (rear main) seal is a direct-fit replacement for a broad list of Acura and Honda applications, including the 2003-2020 Acura MDX, 2004-2014 Acura TL, 2003-2017 Honda Accord, 2005-2022 Honda Odyssey and 2005-2022 Honda Pilot.
Signs this seal may need replacing include engine-oil seepage or drips near the back of the engine and oil accumulating around the bell-housing area. Because an external oil leak can originate from more than one gasket or seal, diagnose the source before replacing.

This part cross-references / interchanges with the following part numbers:
What does this seal do?
It is a rear crankshaft (rear main) seal that seals around the back of the crankshaft where it exits the engine block, helping contain engine oil at that point.
Does the seal rotate with the crankshaft?
No. The seal body stays stationary in its bore while its lip rides against the rotating crankshaft to keep oil in.
How do I know this seal may need replacing?
Oil seepage or drips near the rear of the engine and oil around the bell-housing area can be signs. Diagnose the source first, since other gaskets and seals can also leak.
Will this fit my vehicle?
It is a direct-fit replacement for the listed Acura, Honda and Saturn applications, such as the 2003-2017 Honda Accord and 2005-2022 Honda Pilot. Check the Buyer's Guide tab for your exact vehicle.
What numbers does this seal interchange with?
It replaces BS 40685, 91214-R70-A01, 91214-RBB-OO3, 91214-RCA-A01 and 91214-RKG-003. The MAHLE manufacturer part number is 67766.
