Question on Boxster Air Oil Separator

I have a 2009 Base Cayman with 34000 miles. I've noticed over the past few months random and excessive stinky white smoke at cold start, enough to fill the shop. It clears reasonably quickly, and does not smoke while driving. The oil was changed about 6000 miles ago, and I check it often. I've not seen a measurable drop on the "electric stick." Yesterday I did a number of short-trip errands without issue, but it felt like the power was down it goes alright, just not crisp in acceleration. This morning at cold start, the CEL came on. Reading your article, I do recall hearing a high-pitched whine on first start after garaging it for a week or so during bad weather excessive crank case pressure? I pulled the oil cap while running...significant vacuum pull and the idle is very rough This was expected, the vacuum was not. I will have the ODB II code read tomorrow, but I think I may have an AOS issue causing a mixture problem. Or could it be something else related? Your thoughts? In my research, I noticed there is a difference in the later model AOS mount points. Is there any specific difference in the replacement process? Special tools or pitfalls? What else should I examine in the troubleshooting process? I've only had the car a few months, and the PPE revealed none of these issues not surprised. Any additional guidance or advice is greatly appreciated.

The procedure for replacement is different, but not too much. This does sound like it could be your problem, I would suggest checking fault codes as you plan to and crankcase vacuum.
