After the install, their is a period of time where oil will still be in the system. This is a couple days while it gets sucked through the motor and burnt up.
However their should not be a increase of oil through the PCV system. And if you are having lots of smoke under boost and start up you need to have the vehicle inspected.
It could be a blown turbo, cracked piston ring, or cracked ring land. I would recommend having the vehicle looked at.
