What area is the leak coming from ?  Are you sure its gear oil ?
    Alot of times its the axle boots . You also have a mainshaft seal . This seal leaks between the engine and tranny and will dump lube on your clutch. There are a few other places that it will leak from.
     Keep the fluid level up and you will more than likey make it. Your call
     Good Luck !!

Well I made it back to chicago. . . . .  In an air conditioned tow truck  :cry:

The bus ran good all the way to about 60 miles south of chicago.  I wanted to get gas one last time before getting into traffic.  I came off the exit ramp and it died, i poped the clutch and it got going and made it to the gas station.  I had lunch and went to get going and the bus wouldn't start.  I pusdhed it around the parking lot to jump it off the small hills and nothing.  A jump wouldn't work either.  Finally got as tow truck and found that the motor seized.  Not sure how that happened, no lights and the engine is full of oil.  The fellow who sold me the bus is shipping another motor up and Ill get it in over the weekend . . . . what an adventure

Thanks . . . . Nope I was real carefull about keeping the speed low.  The P.O.  told me if I pushed too hard, I'd be on the side of the road with a blown rod . . . .
