Sounds like a plan, i'll try them out later. If they didn't swell enough i'll get some diesel. Besides, i hear its a bitchen cleaning product. And a badass penetrating fluid if mixed 50/50 with atf.tbpmusic said:Never been a huge fan of PB Blaster, just never worked that well for me.sakibomb said:I tried that but they didn't do anything. I soaked them in there for a few hours and tried again and they still didn't expand. I honestly forgot they were in there, i'm sure days later they are bigger than hell. If they don't fit i'll just stick them in the deep freeze. Give it a few mins and try and fit.
Anyway, a quick (less than one hour) soak in Xylol (from a hardware store) is guaranteed to swell up and soften those o-rings (or any rubber part, like intake manifolds, etc.).
Don't worry, they will shrink back.
Ordinary diesel fuel will do the same thing - see the "Hard Rubber" post, here somewhere.......
