MAHLE Original Buick Century 81-79 Rear Main Seal Set

Victor Reinz is known for making well-built engine components, and this rear main seal set is no exception. This is the seal that sits around your crankshaft where it exits the engine block, and it's crucial for keeping oil where it belongs. If you're noticing oil leaks from the back of your engine, especially around the transmission area, this seal set is likely what you need to fix it. It's designed to fit a wide range of vehicles, including models like the Buick Century, Pontiac Firebird, and various GMC trucks from the late 50s through the early 80s.

This seal set is made to meet the original specifications for your engine. A good seal prevents oil from escaping the crankcase, which not only keeps your engine bay clean but also ensures your engine has enough oil to operate correctly. Replacing a rear main seal can be a bit involved, often requiring the transmission to be removed, but using a well-made seal like this one from Victor Reinz means you're installing a part that's built to last and perform as expected.
