General Information
Injector Protrusion
Injector protrusion can affect power from the engine. In
addition to a single sealing washer (A) on the injector, the
thickness (B) of the head gasket controls injector protrusion.
Thicker service head gaskets are used when the head
surface on the block has been refaced.
