I guess when my warranty runs out I'm going to Zspeed route.

Yeah, they replaced my CSC and pilot bushing. The noise has come back. So it wont fix the problem. That might not be the problem/sound.

The CSC is prone to failure and/or leaking. Never was known to make a noise problem. It would cause the clutch pedal to be stuck or no actuation if you lost all the fluid.

I don't think they upgraded the CSC, but may have improved manufacturing process. Cant say for sure.

I'm going to drive on this second CSC and make more notes of it. See if noise is consistent again.

I wont do CMAK till warranty is over.

They have not made a more robust CSC.

That's all it is. New number. Nothing has changed.

"The CSC has been failing for 10 years; this seems like a design flaw."
"Well, let's change the part # first and see if that fixes it."
