    I list this turbo in 3 months ago brand new because I was told that if oil gets through that pipe change the turbo. I tried to clean the air dryer with dawn following a video on YouTube and it looked like it was working . Today I see that oil is leaking and getting into that pipe that connects to turbo and air dryer what can I do about this if I already replaced the turbo

    If those clamps are tight there should not be any oil on the outside of that pipe in the picture. You need to look inside the pipe for oil. This can happen if you have too much crankcase pressure in the engine. You might have too much pressure due to breather tube or filter being clogged or your engine may be worn out. This video explains turbos . Around 4:50 in the video.

    Just check and see if there is oil on the inside of the pipe off of the turbo to the charge air cooler. How long have you drove it since putting on the new turbo? Does your engine sound like it is running correctly? Are you adding oil frequently?

    Better check the drain for the turbo. If it’s clogged, oil will push past the seals and into the turbo. A new turbo shouldn’t be pushing oil into the charge tube or CAC. BUT, a clogged drain tube will cause it to happen on any turbo.

    It’s been running fine and no it’s not leaking bad that is draining the oil fast. I drove it for 3 months with new turbo

    Is that the tube under the turbo?

    Yep. Comes out of the center section, where the bearings are located. Feed goes in the top and drain out the bottom. Can’t be any kinks or restrictions in it. You might disconnect it and see if you can run some type of steel cable (not your dipstick) down through there, just to make sure there’s no sludge or other buildup inside it.
