Lower Valve Cover Gasket for GM Duramax

If you’re pulling the valve covers on your Duramax, don’t overlook the lower valve cover gaskets. They may seem like a small detail, but they’re critical when it comes to keeping oil where it belongs and avoiding the hassle of future leaks. The Merchant Automotive Lower Valve Cover Gasket is built for the job, giving you a dependable seal between the valve cover and cylinder head on 2004.5-2016 GM 2500HD/3500HD trucks with the 6.6L Duramax. These gaskets take a beating over time. Between constant heat cycles and exposure to oil, the original seals can start to break down, especially if they’ve been removed during previous service. That’s why it’s a good idea to replace them any time the valve covers come off. This gasket is made to match OE specs, so it fits right the first time and keeps everything sealed up tight once you're buttoning the engine back together. It’s important to note this gasket is sold individually, and since each engine uses two, you’ll want to grab a pair if you’re servicing both sides.
