Clutch fluid questions -->
Ok, I took the lid off my clutch fluid reservoir for the first time ('04 coupe w/ 6500 miles). What's the deal with that black funnel/cone shaped plastic/rubber piece that sits on top of the fluid? What is it for?
Also, my fluid looked a little dirty and had some small black particles floating in it. Is that normal?
When I went to put the funnel shaped piece back in, it made the fluid overflow and spill out. What's up with that? Is there a special way to put it back in or something?

the black rubber thingy is to minimize the free air volume. air is laden with moisture... Moisture and heat turn the fluid black the little solid flecks are a precipitate ... It means it is time to change the fluid.
the insert should not cause on overflow unless the master was overfilled to start with..
Use Valvoline Synthetic DOT3 + DOT 4 fluid. it resist mositure pick-up better thant DOT 3 fluids and has a higher boiling point

The black particles are pretty normal. Many people, myself included, use the "turkey baster" method to suck the old fluid out of the reservoir and replace it with new fluid (leaving room for the little black cap as mentioned above). You will have to do this suck and replace effort several times over a period of weeks before the particles stop leaching out of the seals and lines and the fluid will stay clean.
Bleeding the clutch is the better method to replace the fluid, but bleeding the clutch is a nightmare as the bleed port is on top of the housing and requires removing the center section of the exhaust and the tunnel heat shield which has about 36 bolts holding it in place. The turkey baster method is the lazy man's alternative to get new fluid in the system.

I change mine the lazy way too, and I try and do it before each track trip.
