I have a 1994 Integra LS

just over 200,000 KMS

Not driving it right now cause it possibly needs a new clutch (so it seems anyways)

Also.. when I let it run, after about a minute some black stuff..almost like really watered down oil comes out the exhaust.

Any Help on what I can do. How can I check if its the clutch thats gone and not the tranny/syncros or something else, and what would you diagnose as the black stuff coming out my exhaust?

Any help would be greatly appreciated.

Thanks
