Hi all,
    I just purchased a 74' TR6 and have a leak in the o/d unit. The 
leak is worse when the o/d is Not engaged. Oil leaks out from behind 
the copper washer and nut (upper right) that bolts the back case 
to the main case. Tryed new washer but no luck. The leak is large 
enough to cause a steady drip of oil down on the exhaust and ground.  
Any body knows what causes this and what must be done to rectify it?
tks
