FIGURE 1 - INLET MANIFOLD GASKET CLIPINSTALLATION
Some early produced 5.0L and 5.7L TBI engines were built with stainless steel dips that fit over the intake manifold 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.
