    Ok, got under the truck over the weekend to take a look - not the clutch line. The piece of the slave cylinder that the pin goes through was cracked and let the clutch line pop right out. Looking at it, I'm convinced that the seller buggered it up when he replaced the line. Another good reason on why I do my own work...

    So placed the order for the parts through RockAuto and hope they will be here this week. Why the fook they made the slave out of plastic is a whole 'nuther matter... Say what you will about foreign vehicles, but at least my Toyota has a metal master and slave and a metal line that threads into each end...

    Figured that I'd give an update after a month here. Replaced the slave and things have been working fine. I'm still a bit wary about the whole plastic components issue, though...

    Everything seems to shift smoothly and I'm trying to convince myself that it was just a matter of fourteen years of stress on plastic components - or that when the seller worked on clutch line he stressed the slave cylinder connection. We'll see what happens.

    I'm beginning to look at the options of swapping components. Part of the problem is that the master and slave cylinders are plastic and have a somewhat unique fitting for the lines that involves a retaining pin rather than typical hydraulic fittings. If I can find a master and slave that will work without serious fabrication work, I'll change everything out and have lines made up.
