    Black spot on rear turbo

    Hello guys,
    My rear turbo makes a black spot, just where the turbo cold side meets the pipe that goes to IC. It is very strange, it looks like exhaust tail pipes blackness.
    I have cleaned it a few month ago, but it appeared again.

    Any ideas? Thanks.

    Probably oil. Every platform with small stock turbos I've dealt with always had leaky turbos.

    I am sure it's not oil. I put my hand there.

    Turbo mole. If it becomes 3D then you should see a doctor.

    It looks exactly like carbon exhaust, but there is no exhaust in that area.
