Well i have had a motor oil leak for a while now and it has gotten worse. I had somebody look at it and they said they think it is coming from the power steering pump! I dont really know much about mechanics but is it possible for motor oil to be leaking from the power steering pump? If not where do you think it is coming from? Also i had some greenish sluge come out of my blow-by tube (i guess, it's the tube that is on the front drivers side??) my oil looks fine not milky or anything. what would cause green sludge to come out of the blow by tube of a cummins with 123,000 miles? any help would be great and thanks ahead of time!
