I'd have someone pump the clutch pedal while looking underneath at the clutch arm to see how much travel the arm has. If it's hardly moving at all, you know something is going on with either the clutch master cyl, slave, or perhaps the clutch damper (I assume Rodeo's have one of those, too).

Do a search on "clutch damper" or just "damper" as there are plenty of posts on the subject.

Unfortunately if it's not an issue with the hydraulics, it's either a problem with the clutch itself, or trouble with the transmission input shaft pilot bushing.

When you put your 3.4 in did you press in a new bushing? BTW the Oilite bushing is self-lubricating and isn't supposed to be greased.
