Re: bad noise
Good luck troubleshooting the clutch. My 85 had a bad slave cylinder that would be fine for like 2 days after you bled it, then it would slowly leak fluid until the clutch would hardly work. Very embarrassing to grind gears when you're a good driver! LOL. One morning I had to push it backwards to get out of my driveway cause it wouldn't go into Reverse. Your problem sounds like a pressure plate or flywheel problem, though or maybe a foreign object inside the bellhousing like you said. Whatever it turns out to be, I hope its something easy.
