New 'rrrrrrrring' sound in my 82 1.9na diesel 4 speed vanagon.� Looked over the engine for any smoking parts, thought maybe something might have been rubbing on something.� Nothing at an idle.� Not noticeable in 1st gear, mostly hear in 2nd and still present in 3rd and 4th, but mostly 2nd.� it's a deep whine/rrrrring sound. It's strong and consistent, maybe it fades in 3rd and 4th as the engine/road noise increase? � Nothing noticeable at this point with the transmission and i can't tell that there's a loss of power, don't have much to lose!� definite rrrrrring sound though.� any ideas on where to start looking around?� 

thanks, Steve
