Product Details

The Clevite / MAHLE GS33757 Valve Cover Gasket & Fuel Injector Seal Kit is a comprehensive OEM-quality replacement sealing kit engineered specifically for the 2001–2004 GM 6.6L Duramax LB7 diesel engine. This all-in-one kit delivers everything needed to restore proper sealing around both valve covers and injector bores, helping eliminate oil seepage and combustion blow-by common on high-mileage LB7 engines.

Key Features:

  • OEM-Grade Quality: Manufactured to meet or exceed original equipment specifications for a precise, factory-fit installation
  • Complete Kit: Includes valve cover gaskets and injector seals — all components needed for a thorough valve cover and injector service
  • Premium Materials: Constructed from high-quality sealing materials capable of withstanding the thermal and mechanical demands of the 6.6L Duramax diesel
  • Leak Prevention: Provides reliable sealing around valve covers and injector bores to prevent oil seepage and combustion gas blow-by
  • Trusted Brand: MAHLE Original (sold under Clevite branding) is a globally recognized supplier of OEM sealing components trusted by professional technicians and OEM manufacturers

The GS33757 is the go-to seal kit when performing injector replacements or addressing valve cover leaks on the LB7 Duramax platform. Designed as a direct factory replacement, it restores engine integrity without modification.

Quick and easy! Thanks for the convenience!

Fast, easy checkout!

good

web site easy to use, found part we needed....hopefully it will fit when we get it Recieved part...didn't have a dipstick attached and then couldn't pull up the same picture which seemed weird. Cap fits so we will use it without.

I recieved the wrong mirror part for my passenger side 2011 honda oddysey. I have been trying to call to see how to return it and get the right one, but everytime I call they transfer me to the return department and I've been disconnected 3 times after waiting a long time on hold. Can some one please call me at 941-962-5637 to fix the problem? I believe the correct part that I need is Honda Part No.: 76203-S5S-A01 Mirror Sub Assy., R. (Sr1400)

awesome parts dept.
