Only pressure was the return spring.

Funny, there was no warning. It was like a cable clutch, one day, the
cable snaps! Normally with Hydraulic clutches you have some warning,
feels funny, leaks, etc. I looked at the slave particularly and could
see no leaks there. Nor under the car.

Well, as you know, modern clutches have the slave inside the clutch
mechanism, not outside like the 95/96/97 V4's. So you replace the whole
damn thing. $1,250. US dollars in Denver, CO.
