L5P Duramax Valve Cover Gasket Set | Mahle VS50966
Premium direct-fit valve cover gasket set for 2017–2019 GM 6.6L Duramax L5P engines. This Mahle VS50966 set includes both left and right valve cover gaskets and is engineered to restore factory-level sealing performance on Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks.
Why Replace Your L5P Valve Cover Gaskets?
Valve cover gaskets on the L5P Duramax are exposed to extreme heat cycles, high mileage, and constant pressure. Over time they harden, shrink, or crack—leading to annoying oil leaks that can drip onto exhaust components, create a mess in the engine bay, and potentially trigger check engine lights or misfire codes. Replacing them during any valve cover service (or as preventive maintenance) is the smart move to keep your 6.6L Duramax leak-free and running strong.
Key Features & Benefits
- Direct-fit, drop-in replacement — No modifications required; installs like the factory part.
- Complete set — Includes both driver and passenger side valve cover gaskets.
- Beaded steel construction — Mahle’s premium sealing technology delivers superior durability and long-term leak resistance under the demanding conditions of a turbo diesel.
- Meets or exceeds OE specifications — Manufactured by Mahle, a global leader in engine sealing components trusted by OEMs.
- Restores reliable sealing — Helps prevent oil seepage, protects engine cleanliness, and maintains proper crankcase pressure.
- Ideal for stock or lightly modified engines — Perfect for daily drivers, work trucks, or performance builds.
