After a hunting trip three weekends ago, I drove my tracker all city driving for two weeks.  After the first week, I noticed the clutch seemed to be acting weird.  It wouldn't grab like I wanted it to.  I was THIS close to not taking it hunting this past weekend, but I was glad I did, because it did great all weekend and drove itself up the grade with no problems, 4th gear all the way uphill until I got to the top.  When I was headed home, no problems either.  Once I got back to flatlands when I was close to home, I was putting it in 5th gear at about 25-30 mph and hitting the throttle to try to purposely make the clutch slip like it was before.  I couldn't make it slip even if I tried, it grabbed jsut fine.  My theory:
I also have a lot of oil leaking from the distributor, leaking on top of the bellhousing. 
Could the tracker just have needed a good, hot, freeway drive to burn off all this oil?  I'm thinking the clutch got oiled from the elaky distributor, sicne there is not gasket or seal between the trans and the engine block, and the clutch got oily...when I started driving it out of town, it warmed up and burned out all the oil, so by the time I got to a serious grade in the mountains, it did just fine.  For the next two days after I returned home, it grabbed great, now it feels like it is oily again.
Would this make sense or not?  Or would I have to replace the entire clutch?
I posted another topic about the fast idle.  If I can't figure out how to do it other than dealing with the vacuum stuff, it's going to the mechanic for the idle and check the clutch.  But dammit, I hate paying someone else to do something I shoudl be doing myself
Any help is appreciated

first thing I'd look at is the clutch cable....if it got tight or moved then it might have engaged the clutch with your foot off the pedal.

on another side of this I've seen more than once that the rod in the clutch pedal got weak and made it that the clutch would not release.

Check the cable from one end to the other, Fix the oil leak and try it. I don't think the highway miles made a difference. Dirt might have gotten in somewhere and messed it all up.

It's odd that it would shift just fine after a decent drive though, and not act up at all, it was perfectly normal after that.  Haven't driven it since I got back.  Last hunting trip this weekend coming up, will be taking it again
