Description
LB7 Injector Gasket Kit with Valve Cover Gasket | 2001-2004
The Merchant Automotive LB7 Injector Gasket Kit includes every seal and gasket needed to reinstall 4 injectors and reseal the lower valve cover on one bank of a 2001–2004 LB7 6.6L Duramax Silverado or Sierra 2500HD/3500HD. On the LB7, the injectors sit under the lower valve cover, so every injector job means removing it. This kit combines our LB7 Injector Seal Kit (copper washers, injector O-rings and body seals), our LB7 Injector Return Line Seal Kit (return line seals and banjo seal) and a new lower valve cover gasket. Reused seals can let fuel leak under the valve cover and into the engine oil, and a reused valve cover gasket can leak oil.
How many kits do I need? Two. Each kit covers one bank (4 injectors and one lower valve cover), so replacing all 8 injectors takes 2 kits.
