Thanks for responses Dennis, Scott and Ken.

I should have included in symptoms that the van is undrivable. I am not able to reliably engage or disengage clutch. My first thought was a worn out master or slave clutch cylinder. I crawled underneath and started playing with the slave cylinder and as I said below... it SEEMS that the clutch arm protruding from the transmission is not "springing back" as much as it should after full deflection by the slave cylinder.

Does that still smell like a bad clutch Dennis and Ken? The service records that came with the van show a clutch replacement not too long before I purchased it and it immediately broke.
