Gary,
I have changed the fluid on three RCAs and didn't have any problems with th=
e gaskets. They were also the green tubes that was involved and didn't req=
uire all of them to be changed.
Your picture shows what I believe to be fluid contamination but the only wa=
y to be sure is to take it apart and clean it.
Good luck,
Daryl
