For you guys out there that know alot more than I do. I really need some advice. My problem is, I may have dropped a piece of one of those plastic rivits down the breather tube that goes to the clutch/transmission. I pulled the clutch cover off, and nothing there, but I notice there is also a passage that goes back behind the rear cover also. I dont know if this is a threat to anything or not.. If anyone can chime In, I would sure appreciate it. Do I need to tear this whole thing apart just to make sure it didnt go back there?
