Well, I finally figured out my clutch leak down problem.
I have been having a problem keeping hydraulic fluid in the master cylinder. I kept thinking it was the line between the master and slave cylinder. Finally got the chance to work on it and nope, it's not the line. I have a new one installed now and it was still a problem.
I never saw any fluid on the driveway, so I figured it had to be the line, but nope! Turns out it was the slave cylinder. I had my wife helping me bleed out the line after I changed to the new one, and I could hear the slave cylinder blowing and sucking air during the process.
Well, new slave cylinder is on the way. repairs to be made as soon as it gets here. I miss driving my old truck.
