So I'd read about this "green stuff" you guys had all spoken about and I'm like wth i never see any green stuff in my hoses...Well I hadn't cleaned out my Optima for a couple weeks after using and just got around to cleaning it, only to find some green goo in the hoses and connections!! WooHoo!

So anyone know what that stuff is? It was a pretty color green almost cartoonish nuclear toxic looking

E-man,
I believe you are indeed correct and it is 'Nuclear Toxic Green Stuff'
Did it taste 'Toxic'.
I am not familiar with the Optima so I cannot advise you if it's repairable but it sounds like you got a result!!
