MAHLE Original Buick Century 93-91 Rear Main Seal Set

When you're rebuilding an engine or dealing with an oil leak from the back of the crankshaft, a good rear main seal is critical. This rear main seal set from Victor Reinz is built to keep oil where it belongs, inside the engine, and out of your driveway. It's designed to fit a wide range of GM vehicles from the early 90s, including popular models like the Buick Century, Oldsmobile 88, and Pontiac Trans Sport.

This seal set is made with durable materials that can withstand the heat and pressure found at the rear of your engine. A proper seal here prevents oil from leaking past the crankshaft and flywheel, which can cause significant oil loss and create a mess. Installing a new rear main seal is often part of a larger engine service, and using a well-built replacement like this one helps ensure the job is done right the first time.
