Lets not miss the point here. The title of the thread was "Another 996 down". That speaks for itself. Turns out, it wasn't a catastrophic failure and nothing to do with the IMS.

Billyboy...remember him? Not the IMS.

SacTown, yes. One out of how many. No one can say.

To call those of us that don't believe the IMS hype "conspiracy theorists", well, that's like saying I am crazy for not believing in Bigfoot and the Loch Ness Monster (from MY perspective).

To focus my "anger and energy towards Porsche" to get them to admit they don't have a problem--that I believe they don't have...convoluted logic at best.

I totally agree with your statement that we are all free to believe what we want to believe. I believe that yes, these engines fail. Yes, sometimes it is an IMS issue. Sometimes it is a cracked head. Sometimes it is a chain tensioner.

But the reality is that all cars fail 100% of the time. I just don't believe in putting a band aid on my finger just in case I get a cut. It certainly doesn't mean I don't think you should either. If it makes you sleep well at night, go for it.

And like I said before, Jake's marketing is excellent.

What have I learned from this thread?

The IMS in Gonzo911's and DreamCarrera's 996s will never, ever fail.

Not if you believe in Karma!

SacTown - lucked out - Porsche paid in full for his crate motor - yes he had to pay labor. Still don't know the details, but it was mentioned that the car had "major" engine work done shortly before he purchased it. I don't think his case is the norm yet Porsche provided a free engine on a used car well out of warranty. The servicing dealer, who I assume performed the "major" engine work, certainly had something to do with that. And, SacTown was well of aware of the "IMS Issue" yet posted more about his interest in mods and audio units - until the engine failed.

I am not a disbeliever in engine failure, just as I am not a disbeliever that lightning strikes people and some of those people die.

I still drive all of my cars, I still go outside in the rain.

And I am somewhat taken aback by how quickly Jake resorts to feigning that he is offended and "out of here" when he is quite outspoken and his accusitive remarks of "vendor haters" and some other less than appreciative descriptions of the members of this community.

He is out of here on one thread and appears immediately on another. If he is not marketing to some degree I wonder why he responded to a member who was asking for a cut away view of an AOS by saying "yes, there is one" - " it's in my new book, you'll need to wait until it comes out".

Not trying to spin things up but let's call it as it is. Doesn't mean it's bad or that it's wrong, but it is what it is.

Sometimes the "it's coming, something is coming, wait for it, it's coming and it's great, and I'm so busy you'll be lucky to be able to do business with me" reminds me of Apple's iPhone marketing. They are genius at creating artificial demand, selling before the product can be seen, selling more than they can fulfill, and having people feeling priveleged if they can actually purchase AND receive one. Their numbers prove that their "marketing" works.

There is nothing wrong with marketing - but again - it would be nice to call it what it is rather than to deny it and act like the involvement is altruistic.

In this case Jake could have divulged what he discovered about Gators engine, yet he directs us to his facebook. I personally have no interest in facebook so I guess I'll turn in and hope I awake for another day of enjoying my 60 mile round trip work commute in one of my 996's.

Quite the thread we have here.

What kind of a car community is this when, those that know the most, flat 6 in this case, is only willing to release information, in a halfly answerd way, and is always based around money?

aviography

While majority of us own a Porsche as a hobby, it should be obvious FSI is a business, a business is in the business of making money, it's not even a non-profit organization.

I might not like the price being asked, but i can't fault FSI for rightfully charging for intellectual knowledge the company invested its own time and expense to develope.

A very instructive tale.

I remember wondering when this thread first started why the dearth of diagnostic investigation instead of the rush to conclude that the motor was toast? I just had to replace an a********r on one of my other vehicles too…

I am glad for the OP that it turned out to be something completely different. In his case it apparently was not a whole lot more cost for him to have it transported to Flat-6 than to an alternative garage. However, for those of us further afield it still makes sense to have normal, basic, diagnosis done prior to rushing to a conclusion. Many of the more “diy” folk on here could/would have figured this one out on their own, or certainly any competent garage would have.

The funniest part was that I had to go to Flat-6’s Facebook page to discover the big secret by watching a video. There is much truth to the sentiment that they are master marketers. I have come to the same conclusion myself.

It does not negate the fact that they do great work, but, as another poster put it, “it is what it is”.

alpine003

Glad it was a happy ending for OP. The Porsche belt tensioners must be REALLY effective.

I think this thread is priceless. Only the regular followers are gonna read through 9 pages of "he thinks, she thinks" so it's only relevant for those that have an opinion. It hasn't turned negative yet but there's still opportunity for Goodwin's Law to prevail!

It was a good read, fun to follow, great outcome (because $300 shipping is a bargain, because that about cheapest I could get to ship anywhere, let alone the most knowledgeable on the continent).

One thing that is a fact is that Gator's avatar is hot.

Logray,

Thanks for the photos. I was the member looking for a cutaway photo. It should really help.
I'm still trying to figure out where the coolant resides in the AOS. It appears that it is only on one side of the diaphragm. I can't really see how that helps the AOS function... If the rubber membrane fails, then there is the potential for an intermix issue.

Best,
TomF

I recently had the LN IMS retrofit done on my 2000 C2. It had a dual row bearing made in Japan. Chances are good you have the same?

Imo000

I'm going to cut my old one apart and figure out how it all works but my guess right now, is that the coolant is only circulating in the diaphram housing to keep it from freezing up.

logray

Yes AFAIK the coolant is to keep the AOS from freezing. There is not much chance for intermix from the AOS because it is vacuum/gravity operated and lack of pressure, unlike the oil cooler which is driven by the oil pump. With the AOS, you might get some residual/light intermix goop (around connectors from condensation or leaks), but likely not full blown intermix like you would see with cracked heads or oil coolers. The common symptom from AOS failure are tons of white smoke from the tailpipes and difficulty removing oil filler cap. A failed AOS and UOA could show coolant in oil, but not oil in the coolant due to pressure differential.
