FIGURE 1:

Some early produced 5.0L and 5.7L TBI engines were built with stainless steel clips that fit over the intake manffold gasket at the intake ports (Figure No. 1). These clips are used to separate the intake ports.

These clips must be reinstalled after any repair that requires the removal of the intake manifold gasket. Failure to reinstall the clips could result in driveability complaints such as poor performance or engine miss. It is also necessary to add a "dab" of RTV sealant, P/N 1052917, or equivalent, to the gasket to head parting line (See Figure No. 1). Clips that are damaged or lost can be replaced by ordering P/N 10074116.
