OG PCV change to top only.

482 19
I am going to change the dip stick moulding for one with a side outlet nipple and connect it with a "T" piece to the pipe returning from the oil trap and going eventually into the intake side of the turbo and wondered what you more knowledgeable folks thought since I'm leaving the oil trap as is. Please advise.

I would just install PCV #6 and nothing further. That setup has proven reliable for countless OG9-3s and early 9-5s. Keep your eye on the rubber parts and replace them when needed. My experience is that they last 10 years or so, as do most rubber parts, and then must be refreshed.

63k is nothing, in any sense of modern car engines. I don't even start to consider age on an H motor until 200k is within view. PCV #6 is well proven, and you need to remember on boosted cars PCV is not a simple matter. I would not second guess the manufacturer without some serious engineering background.
