Okay I did a bit of searching but did not come up with much.

I have a 2004 st3 I purchased last year and after putting about 9000 miles on it i knew it was due for a new clutch (factory dry clutch) with 30,xxx miles. So I pulled the clutch components and noticed that the push rod was all gunked up, and also appeared that the slave has a small leak only when actuating i found by taking it off and giving the lever a squeeze. Since i had purchased the oring and seal kit from l.t. i was going to replace the orings that go on the slave cylinder side of the pushrod.

I would think it would be a good idea to clean out the "tube "the pushrod rides in which as far as i can figure is the transmission input shaft since it seems a little dirty with grease and what not. L.t.'s book does not go into detail on cleaning this out. I was thinking take some acetone and a .22 cal rifle bore brush and clean and swab it out but i am not sure if this would be a good idea or not.

No need to clan it, AFAIK it's getting washed by motor oil .

Slave leaking is a common issue, they are all the same, get larger bore and it will also decrease the lever pressure, save your finders in stop-n-go traffic

Your old o-rings were probably a bit worn (mine were) and some of what is in the shaft is a combination of DOT 4 (or whatever) leaking from the slave and oil. If you put the pushrod back in from the clutch side, then the o-rings will take much of that along with it. Then just clean off the pushrod and o-rings and you're probably good to go.
