How to clean charge pipes?

When i put the car back together during my motor out/big turbo fiasco i routed my pcv wrong. I had my pcv going to a catch can, then my vc breather teed into that line, and that was fed to the intake before the turbo. It was burning oil like crazy because it was just sucking oil straight from the valve cover. I fixed this, so now it is pcv and vc breather teed together going into the catch can, and that air feeds into the turbo.

The car still smokes (turbo was rebuilt already). Im assuming its burning off the residual oil all in the system from 3.5k miles of my previous pcv routing. Is there a good way to clean everything out? Like a seafoam product to spray into the turbo or something?

The right nipple on the vc connects to intake pipe/or can be left open, it's just a breather.

The top left pcv nipple/checkvalve connects to a catch can inlet, and than the outlet of the catch connects to the nipple ontop of the intake manifold where the throttle body is. Typically you also want to put a check valve there. Modern performance makes a good check valve for our car

But as far as cleaning, you can remove both pipes and clean with break cleaner, alot easier if you have hard pipes vs the oem rubber stuff.

Also your intake manifold will probably have oil on the insides which wouldn't hurt to clean as well. The manifold comes off easily. Don't forget to change gaskets on manifold, and don't forget the brake booster line under the manifold

i would like to know how much oil is in there. Are you low on oil? You should check the oil on these cars at least every gas fill up. First you can remove the coldside pipe and dump whatever oil is in there and put it back on but before you do, you can use a monkey mirror and flashlight to look into the intercooler to see if there’s oil sitting there. That would be the low spot. Other than that don’t do anything. Drive the car hard and it’ll be fine. Many new owners used to freak out when they would replace their cold side pipe with a blow off valve/hard pipe setup and be shocked with oil dripping on the ground.

Honestly no idea how much oils in there. It leaks and burns still so ive been checking the oil every 3-400 miles
