I bought a USED TE44 off ebay. Got it today. With the exhaust elbow off,the fins are VERY OILY looking(exhaust side only)! It has a little up and down play but the fins don't rub the housing. The guy said it had 5000 miles on it and it was good. Doesn't it mean the turbo bearings are shot if the exhaust impeller is soaked with oil or could it be something else?
