Hello my name is ***** ***** I will help you with this issue.
How many miles are on you vehicle? Sounds to me like it could be 1 of two possibilities.
1. Oil level is not correct
2. The turbo seals are bad
The first step is an easy fix while the second not so much. These engines are know to have turbos go bad all the time. I was replacing them all the time while under warranty. Depending on the mileage, if you are sure the oil level is correct then when I get the mileage from you I will make some suggestions to the turbo issue.
Yes any type of crankcase leak can cause an issue, but with that low of mileage I would suggest looking over all the crank case hoses and if the vehicle still smokes then take it to the dealer and pay the diagnosis fee. When they give you an estimate ask for Goodwill assistance. BMW is having a lot of issues with the Turbo seal, crankcase ventilation and the fuel system on that engine due to the reversed intake and exhaust setup. If you have not had the vehicle at the dealer in a while there may be open recalls for these items. Another check you can do if you are skilled enough is pull the turbo inlet hoses back and see how much oil is in the turbo, if there is a substantial amount of oil then it is also in the intake and pushing that oil through the motor as well. The Turbo seal going bad on the N63 causes all kinds of issues with pushing oil everywhere to the point that in some cases the intakes have to be removed and the oil has to be cleaned out.
I would like to also add that one of the crank case hoses is missing the clips at one end to keep it secured and it also has a hose connected between the two ends. This hose should be replaced for sure. The pressure build up could cause the hose to come disconnected.
I will have to open this question to someone else. This amount of diagrams and information is to be honest is books and books worth, plus the repair will run into a huge amount of unknowns. I am telling you this because in the limited information environment you are at it is going to be an enormous challenge. I will leave it up to you, but I am not sure you will get all the information you will need to get the job completed. I will be waiting for your reply on this.
Ok I will opt out. I will keep an eye on this, let me know if I can help in the future.
I have forwarded the request for you.
