Re: 996/997 engine failures
That's exactly what I was told. Apparently, the GT3 and Twin Turbos are not affected because they are based on the older pre-water cooled design.
I was told it wasn't a question of "if" the engine would go, just "when." If that's true, then more people most be aware of this.

I've been told that Porsche dealers are doing a lot of engine replacements. The failures have something to do with crankshaft vibration or warping--I'm not sure of the details. Has anyone heard this before?
Hmmm. Not sure what to make of this. Not sure how a car can make it to number 1 on JD Powers report with engine problems. I guess just another reason I don't put much weight in JD Powers. If my engine goes I hope it is right before the warranty expires or right after I sell the car.

Re: 996/997 engine failures
I've not heard of this on the M96 engine, nor the M97, but I am aware of one M97 that did have to be replaced on an '05, reason unclear.
The only widespread engine problem I was aware of on the M96 was the rear main seal leak, which has occurred on some M97's so it's not yet solved. Hopefully, at least improved.

These problems sound like the problems I was told about. This is a very knowledgable and credible source who would not say this if it were not true. But I'm wondering why I haven't heard this before. I had an early manufactured E46 M3 which blew an engine, but I had no trouble verifing that it happened to hundreds of cars built in October/November '01. Apparently, this 911 defect (if it's true) is inherent in the design and not fixable.

Sounds like a nasty rumor which never made it out of the larval stage.
This comes from someone with intimate knowledge--they're doing two engine replacements a week. The problem is with the Boxster/996/997 watercooled engines. The Turbo and GT3 have the older crankcase design, I'm told. Checking further on the web, it does seem that Boxsters are having problems.

Re: 996/997 engine failures
Porsche came out on top in the J.D.Power survey of initial quality. That means fairly new cars. The problem doesn't crop up right away. My Boxster engine was replaced after it ejected part of the valve train right through the valve cover. Someone at the dealership told me that the engine failure rate was between 5% and 7%. The GT3/Turbo block seems to remain bulletproof. My neigbor's 996 had the engine replaced. That's two engine replacements out of five Porsche's on my street.

I just remembered: my dealer told me the M97 was replaced because of "piston slap", whatever that is, and for whatever that is worth.

Re: 996/997 engine failures
surfing the net for engine failures seems to reveal a lot of 997,996, boxster and M3 engine failures, these are low production vehicles, so the ratio of engine failures to number of cars sold would seem to be exceedingly high, most of the failures seem to just happen, i.e not tracking the vehicle, dont see how anyone can keep enjoying the vehicles, waiting for the engine to self destruct.

Re: 996/997 engine failures
I've been surfing Porsche forums very frequently for over 3 years now, and I can't say that engine failure on the M96 or M97 has been a common problem I've seen discussed.
I don't believe this is a real issue.
Forums like these magnify the problem because you only hear from those with a complaint. The true denominator is unknown. Despite that, as I said above, engine failure as a systemic problem has just not been an issue until this thread, at least that I've come across.
I suspect someone's trying to stir a pot.

These are my thoughts too. We need waaaaay more information from substantiated sources on this before we start drawing E46 M3-type parallels.
Consider that we have had the 997 engines in the hands of consumers / daily-drivers worldwide now for 21 months-- any statistically significant pervasiveness of lower engine failures would not be suppressible or stay under-the-radar for this amount of time. As Silver Bullet pointed out, these things are normally magnified in the context of an internet forum, not downplayed.
A case could be made that in consideration of future resale value, owners may be reluctant to publicly announce their own car's major component failures to a group of their local club members or neighborhood gazebo cruise-in crowd, but the internet is the PERFECT place to vent with relative anonymity about vehicle problems.
If you add up all of the 997 owners accessing the four or five highest-traffic 997 websites, we're proabably talking a total denominator of 400 to 500 owners. I could be mistaken but I think we've had a total of three (3) engine-replacement accounts posted by contributors on these sites...2 intermediate shaft failures and a non-correctible RMS seating surface requiring casting/engine replacement..... granted this not at all a scientific poll, but far from the avalanche of discontent which befell the BMW E46 M3 chat boards around 2002 when motors began to fail wholesale...I owned two E46 M3's so I was right there.
A conspiracy of silence is NOT how anyone would characterize the evolution of the internet dialogue on the BMW M3 3.2 litre engine failure boondoggle.
Thom, I recall reading some of your prior posts going back some time and I'm not accusing you of trolling or anything like that....is this a dealer technician at a high-volume dealer that you have first-hand info from? How many replacement engines are we talking about relative to overall sales? I would be happy to personally take on the task of aggregating any and all information on 997/987 engine replacements. Step up, post here or PM me anyone with specific information. As a hopelessly addicted 997 owner I want to know about this stuff in intimate detail!!!
Re: 996/997 engine failures
Did you notice any difference in the engine performance, such as rough running, vibration, before the crankshaft gave out?
I started my car then I hared a strange sounds from under my car, I turned off the engine I looked under the car and I so oil dripping from every where, and it has only Km16,250
2005/997s

Re: 996/997 engine failures
Found this pdf file on 996 engines and reliability, might help if your on the fence on buying a 997 do to engine worries (takes some time to download)

Damien, I sent you my cell number, feel free to call.
My motivation for starting this post is certainly not to start rumor or "stir the pot." I simply want to ascertain whether or not engine failure is widespread. Frankly, it would seem that it is not, based on responses to this post. You make the point that maybe only 500 Porsche owners visit forums, but they are all knowledgeable enthusiasts who know what's going on--that's why I came here for an answer to this.
I did not give detail about who warned me of this because I doubt he would want me to, but I will try to speak with him in the next couple of days and report back.
I got the very first 997 delivered by Silver Star Motors on Long Island (not where I heard this); I've got 20,000 miles on this car and love it. I'm just trying to determine whether or not I can keep this car beyond it's warranty. One thing I like about Porsches is that they are supposed to be bulletproof--I will be very disappointed to find that that is not true.
