[s-cars] Question about injector inserts and O-rings

[David Forgie]

Now that I have finished the T-belt job and have been snooping around the engine for any leaks, e.g.
 stupid-ass turbo hose banjo bolt, I notice that my RS2 green top injectors are dirty where they go
 into the intake manifold. They are "only" 6 years old but they seem to be leaking (nothing to do with
 26 to 28 psi of boost <wink>).  I figure that I could replace the injector inserts and the O-rings but I 
find out that the inserts are not stocked normally.  I *could* just do the O-rings, at least in the short
 term.  

Anybody with any injector insert experience/suggestions?

Here is what my friend Kate says about cross-overs on the inserts (20vT engines only):
