Hi all! I've got some updates from the past few months:

- new clutch slave cylinder and hydraulic lines installed
- dropped and discarded leaky aux fuel tank, and redid fuel lines to OEM tank
- went through radiator hoses and replaced old ones
- assorted rust grinding + converting
- new tires on the rear after one blew out

I started the van this weekend for the first time since fixing the fuel tank and replacing the clutch slave cylinder + lines. Fired up just fine with some fresh diesel in the not-leaking tank. I then rolled down the driveway a bit to test out the brakes (they work pretty good for not being adjusted yet), but after all my work fixing the clutch actuation I still couldn't get it moving under it's own power -- I let out the clutch while in gear and nothing happened. So I was pretty bummed that evening, not knowing which of many things could still be wrong with the clutch or transmission. But the next morning, I put the front up on jackstands to get the drive wheels off the ground, hoping to see if I could shift through the gears and see some wheel rotation. It worked! I was able to shift through all gears, including reverse. I tried getting a video to demonstrate, but I accidentally was in picture mode instead (whoops).

So it seems to me just that the clutch is grabbing enough to spin the wheels when there's no load, but not grabbing enough to drive the vehicle.

I'm thinking it's one of three things now:
- clutch release fork needs adjustment; currently not engaging enough
- clutch friction surface is worn out and slipping
- pressure plate springs got weaker from sitting compressed for 10 years

I'm going to try adjusting the release fork first, since the other two mean dropping the transmission.
