MAHLE Original Buick Commercial Chassis 96-91 Rear Main Seal Set

If you're dealing with oil leaks from the back of your engine, a rear main seal set is likely what you need. This is the Victor Reinz JV554 Rear Main Seal Set, a well-built component designed to keep oil contained within the engine block where it belongs. It seals the gap between the crankshaft and the engine block, preventing oil from escaping onto your transmission or the ground.

This particular seal set is made to fit a wide range of vehicles, including many Buick Commercial Chassis, Buick Roadmaster, and Chevrolet Camaro models from the late 80s and 90s. Victor Reinz is known for making solid engine components, and this seal is no different. It’s a direct replacement part, meaning it’s shaped and sized to install in the factory location without needing any modifications. Replacing a rear main seal can be a labor-intensive job, often requiring the transmission to be removed, but using a quality seal like this one ensures the repair is done right the first time.
