Clutch Fork

I had searched for this question - how do I know if the clutch fork is actually bent or not?

I left my PSD sitting for past two months, believing that the problem was Sync rings inside Z5, were worn out.

My friend came to check other car and noticed that my truck was sitting for long time. I explained the problem, that stick won't shift from any gear while I was driving. Have to turn the engine off in order to change the engine, so I was stuck on 2nd gear to drive around a bit, just on the block, nothing farther. My friend suspected that it was clutch system, not the tranny.

What happened was that I checked under truck on the slave cylinder as he said that it is either that or the clutch fork. We played with it for a bit. I put slim (just a piece of metal with hole in middle, allowing the rod from slave cylinder to seat in there) between clutch fork and slave cylinder rod. Turned out that he was right. I am able to drive around and shifting. The reason why he suspected that was that he noticed that clutch pedal went all the way to the firewall and told me that it was not supposed to do that.

So big question is which one is at fault - slave cylinder or clutch fork?

After reading several posts, throw out bearing could be source of this problem?
