Duramax First Generation: 2001-2004 (LB7)
Hello, new to The Forum. I have a 01 Chevy 3500 with the lb7. A little history, the engine I pulled and went into at 195k miles and changed head gaskets because of an external coolant leak. I replace the gaskets with Fel-Pro gaskets and new head bolts, not head studs. No injectors at that time...
