[s-cars] Intake manifold, injector, maybe leakage

[Elijahallen92 at aol.com]

Hey guys, the cars is running strong and I am very happy but I noticed  
around 4 of 5 injectors on the Dahlback intake manifold that there is a yellow  
stain like fuel is leaking out around them and drying on the manifold. Is this  
something that anyone has experianced? The injectors are in good condition.  
Could the insert around the injector be shot?
