I have an odd sound in my 91 stock nsx. Every now an then I get a chirp sound when I release the clutch in first gear. I have now found that I can repeat this every time if I am just slowly rolling or even from a dead stop if I start off in 2nd gear. The sound is more of a chirping sound versus a squeak. Is that the clutch or throw out bearing starting to go bad? 91 with 72k miles, unknown if it is the original clutch.
