looper, IIRC the current head of Porsche is a finance guy...

While my CS will likely not be tracked I would have like to think it could without worrying about the engine hydrolocking itself. It's a bit disappointing to find out that the psuedo dry sump is more a marketing thing than a real way to keep the engine working properly under high cornering loads. In all of engineering there are compromises required to balance competing requirements. I guess this is one of them. Still a disappointment.

Personally I would have gladly given up the goofy key/entry/security/immobilizer computer systems for a decent AOS and/or dry sump.

This oil burning is enough of a problem that I won't buy. Plain & simple. I won't even consider buying new or used until this has been fully adressed. Porsche AG better acknowledge the oil burning problem properly, formally, quickly & completely. AND FIX IT!

This is too reminscient of the series of engine problems that plagued the Boxster. I guess Porsche AG will learn the hard way. They jacked a lot of Boxster owners off and the early editions spent to much time in the shop that the Boxster became notorious. One didn't buy new but waited for some other sucker to sweat out the repairs and then buy one that didn't need to be in the shop all the time.

Porsche has "advanced" and become like all other car manufacturers. Quality Control went out the factrory long ago--back in the air cooled age of the 911.

That is an admirable sentiment. However, telling it to us here isn't going to fix anything. You should email/write/call PCNA directly and let them know how you feel; otherwise, it's just that much more noise on another internet forum to them. Even if someone at PCNA reads this forum, a post just isn't going to have the same impact as a direct communication.

Also, while you're at it, sign the petition, if you haven't already.

I honestly think we're all **** out of luck. If porsche steps up to fix this, they're going to have to also step up and handle the RMS leak issue... among other "quirks" like the infamous 996Turbo 2nd gear pop out issue.

I don't remember exactly, but doesn't this fall under the UCC implied warranty of fitness? Seller in this case, has reason to know how it would be used (performance driving) and promised, in writing, that the race-derived engine design would be capable of handling high G cornering. Class action? My Contract knowledge is damn rusty hah.

As an aside, I wonder what Porsche then does with the Caymen they use at Porsche Driving events.

For the past two years in the Denver area, Porsche has had pseudo-AX events where you could drive their Caymen around a course at high speed with a Porsche driver in the passenger seat, then around the course with the Porsche driver at the wheel.

Many, many tires gave their lives in these events. :-)

Yet none of them ever smoked at all; does that mean Porsche installed a different AOS on these cars?

Would an 'Oil Catch Tank' fitted between the Standard Air/Oil Seperator and the Plenum/Thottle body work? -

If it could be fitted low down, so that it could be emptied from underneath occasionally, and also ensure that any oil drains down - not up, into our airways.

Would this be a simpler modification?

What would the drawbacks be?

Here's a couple of images of the Motorsports Vapor Oil Separator, P/N 996 107 926 00 (Porsche calls it a VOS, not AOS as we've been incorrectly abbreviating)



It looks pretty complicated. There are two main chambers, and they're much bigger than I expected. I'll post some images of the stock VOS when I get it out, but I expect it to be much smaller. The stock P/N is 996 107 026 00. From the parts catalog, it looks like the stock unit only has a single main chamber. There is some sort of manifold on top of the Motorsports unit that connects the chambers, with a diaphram that must operate a valve. There is a drain at the bottom of both chambers. There doesn't seem to be any way to open it up and look inside, and I can't see much through the various inlets and outlets, so I have no idea how it works.

This thing is big! I'm not surprised some rearrangement is required to get it installed. More as I progress...

For those who want to do this mod, I ordered my VOS from Tischer's online parts site (http://www.trademotion.com/partlocat...75&catalogid=0). Tischer is a site sponsor. It had to be sourced from Germany, and took about 3 weeks from order to delivery. It was $455 delivered.

I remember a conversation with BillC about just such a setup. Bill - your thoughts?

Someone did their own oil tank on a Boxster and at one DE it splashed out and caught fire so such a homebrew hack might have some drawbacks. Sooner or later someone will have a "kit" for the motorsports VOS or something similar I'm pretty sure.

Attached are two photos of the two-stage VOS (AKA Porsche Motorsports AOS) installed in my car.

I have now run the car through a day of tight AX and a weekend of high-speed, high-load Time Trial sessions at Willow Springs (1:35.7 for reference) with no leaks, smoke, or oil burning. Prior to the installation of the AOS I would use 1/2 quart of oil during a track weekend at Willow.

Installation was done by Vision Motorsports in Laguna Hills, CA.

Krok - in the last photo the tube exiting from the diaphram at the 9:00 position has no hose on it. What about the one in the back of the diaphram (2:00 position in the bottom photo)? Is it connected to anything?

Is that the offending air pump behind the VOS on the right?
