IMPORTANT: All gasket surfaces should be free of oil or other foreign material during assembly. Inspect the engine block oil
gallery passages to make sure they are free from any debris or restrictions.
IMPORTANT: The oil pan on LS engines is a structural member. The alignment of the pan is critical to provide the proper
mounting points for the transmission bellhousing. The rear of the oil pan must never protrude from the rear of
the block. The rear of the block and oil pan are to be flush (Figure 2).
