I think a T-28 would fit in place of the T-25. Just a suggestion. Yeah, this sounded like an oil-seal problem from the get go. On another note, if that much oil was getting into the intake tubing, an oil-catch can is not gonna be your solution. I've spoken to Corky about this because I had very small traces of oil in my intake piping before the turbo. He said that a little blowby is normal, and you will have a little film buildup. If you have drops, then something is wrong.
