Current setting you have will be pushing boost into engine crankcase via intake manifold, this AOS is designed for NA cars and needs to be modifed to be run for boosted applications, otherwise you pressurize the can. The mod basically turns it into a a poor mans dual catch can type setup. You really need two independent cans to do it properly, that being said i'm running this AOS on my turbo setup. I blocked the short hose that goes from can to intake manifold and replaced the check valve on the back of the block with a regular barb fitting(that check valve only opens under vacuum). Its not ideal but it works.
*Edited looks like they put a one way valve ( the red piece) to stop what i mentioned from happening, maybe that failed?
If you are after a VTA can, I have a brand new Full Blown VTA catch can that I fit then removed a few days later during my turbo build ( its never been run). I had to switch to a recirculated system in order to get my build engineered. Willing to let it got for $100 US + shipping ( im in aus, shipping wouldn't be more than 30 US) let me know sir
