Thanks for asking your question. I will try and help you out.
Unfortunately I have seen this before. If the crankcase filter has been changed and the code still occurs and the dipstick is being push out. There are two things I have seen cause this.
The first is a faulty turbo. When they fail, they can put exhaust down the oil drawing tube and elevate crankcase pressure.
Second is cylinder and valve guide wear.I am sorry. I wish I had better news.Please reply back if you need more help or have more questions. I am happy to assist.
