What would cause the waste gate valve on a CD300 1983 classic diesel engine Mercedes-Benz have oil to drip under the waste gate? Where might the oil be coming from? 2-3 miletrips causing engine not to heat enough may be problem. 180,000 Miles on it.
Turbo repaired for alternate reasons.

 

you mean the waste gate actuator is leaking oil?? the actual waste gate doesn't have oil going through it.
