Clutch master and slave

[Mellvis]

I recently put a clutch in the Ranger (1986 2.9 4x4), or I should say had a local shop put it in. I picked it up and within the 5 mile drive home, it started slipping really bad. It was at a point that I could put it in gear and let off of the clutch and it was as if it was in neutral. While the trans was out, the slave and master was replaced with used (yeah I know, but they where factory Ford parts that I can't afford to purchase right now) ones. After the truck sat for a few days, the clutch worked again. I drove it a couple of miles and it began slipping again, just as before, to the point of seeming like it was in neutral when it was in fact in first gear and the clutch pedal was released.

My question is, is there a check valve in the system that could be sticking so as to keep the pressure plate released and then slowly bleeds the pressure back off as it sits for a few days? If so, where would this be, in the master or in the slave?

You guys seem to know what's going on and I'm confused. I think it's a good theory but I'm not familiar enough with this system to know for sure.

if i had to guess i would say that your slave is bad and sticking and or the master. i learned along time ago that given the scope of a clutch job it makes sense to do it right the first time and use all new parts (still no 100% guarantee that parts are good but it significantly raises the odds that they are ) looks like you need to pull trans back down

That was the news that I didn't want to here, but thanks for the information. Do you know if there is a check valve system in the unit?

Sounds like somebody greased your clutch disc.

Did they offer to replace your rear main seal, and you refused?
