The SPOOLOGIC SL-310-026 Turbo Gasket Kit provides replacement gaskets and seals for turbocharger service on 2011–2016 Chevrolet Silverado and GMC Sierra 6.6L Duramax LML pickups. The set brings together up-pipe, oil-drain, intake, and EGR sealing components commonly disturbed while accessing and reinstalling the turbocharger.

Features

• Upper and lower up-pipe gasket pairs
• Oil-drain flange gaskets and line sealing washers
• Intake O-rings and shaped seals included
• Additional EGR flange gaskets for service access

Sealing and Service

Turbocharger removal on the LML involves more than the exhaust flanges alone. Nearby intake and EGR connections may also need to be separated for access. Replace the seals at the joints opened during the repair, and inspect the pipes, flanges, and grooves before assembly. The exact service procedure determines which supplied components are required.

• 2 Oil-Drain Flange Gaskets
• 4 Additional EGR Flange Gaskets in the Pictured Profiles
