Not needed for a 2003 LB7 Duramax
This gasket is just not needed on a 2003 LB7 Duramax. There is no gasket under the housing and GM uses the o-ring that is around the T-stat to make the seal. Nice gasket and made well but just not needed. I’m not gonna send this back because what’s $7 more when you’re paying $2,200 + $1,600 core for injectors, plus valve cover gaskets and fuel lines! 💰💰💰🤷♂️
