MAHLE Original Chevrolet Express 2500 12-06 Timing Cover Seal

This is the Victor Reinz timing cover seal, part number 67775. It's designed to fit a wide range of GM trucks and vans, including popular models like the Chevrolet Express 2500, Chevrolet Silverado 2500 HD, and GMC Savana 2500. This seal sits behind the crankshaft pulley, right at the front of the engine, and its main job is to keep engine oil from leaking out around the spinning crankshaft snout.

A well-functioning timing cover seal is crucial for keeping your engine properly lubricated and preventing oil from getting onto other engine components or the ground. When this seal starts to wear out, you'll typically notice an oil leak originating from the front of the engine, often around the crankshaft pulley. Replacing it involves removing the crankshaft pulley and the timing cover, so it's a job that requires some mechanical know-how and the right tools.

This seal is made from durable materials to withstand the heat and friction it encounters. Ensuring a tight seal here is important for the overall health of your engine, especially on work vehicles like the Express and Silverado that are often put to the test.
