Welcome to the forum.

The PCV (which is where the only source of oil in the air piping should come from) should not contain enough oil to cause you to see blue smoke. Usually, blue smoke is attributable to worn rings, valve guides, turbo bearings.

If you ARE getting that oil purely from the PCV then something is pushing the oil out the top of your motor. Normally, a small amount of oil vapour escapes the oil separator in the top of the motor and is passed through the PCV into the air intake. This is forced into the engine, leaving trace amounts on the piping along the way, and combusted - that's why in DPF-equipped models, we have to use very low ash formulation oil so that the DPF (Diesel Particulate Filter) isn't choked up.
