That is interesting because you are not listening to what we are saying at all. Not the evidence. Not the personal testimony. Nothing. You have an agenda that is all.

Guys, just picked up a 996tt so I have another forum to keep up with besides the 993tt forum.

I have welded an awful lot of these water pipe sets. Never had to do a failed one but around 75% of the ones I have done had at least one that did not look too good and was close to failure. I disassemble and clean every trace of adhesive off the tube and the socket. It is very easy to see which ones were going to stay put and which ones were close to coming apart. A few tracks around here mandate some form of repair. Some people pin them, I have no issue with pinning just wonder where the swarf goes from the hole drilling. There would not be much, but even a little can add to the waterpump's marginal seals issues.

From my experience, this is a timebomb and eventually it's fuse will light. Find some way to mitigate it.

That couldn't be further from the truth.

Hi,

I am with a law firm that is looking into reports of catastrophic coolant leakage in Porsche 911s, similar to what you have been discussing. If you have experienced this issue or are interested in the investigation, please feel free to email me at emo@girardgibbs.com, or give me a call at (866) 981-4800. You can also visit our website http://www.girardgibbs.com/porsche91...investigation/.

Thanks,
Ellen

This answer is a perfect example.

Such a pile of ****, I certainly hope that the engineers for the porsche coolant tubes in the late 90s and early 00s are designing something more in line with their training, like water balloons or bendy straws. Whatever was the problem with the pressed in barbed nipples that have been used for years without failure? Apparently re-inventing the wheel with such technology is just what these cars need.

Put this in the same waste of time I spent two years ago with my cayenne turbo that was so advanced that they decided to use a space age polymer with stainless collet inserts. You may get 70k miles out of these coolant tubes before they fail under the intake and the extremely caustic porsche coolant destroys the starter and only if you are lucky will run down the back of the engine valley out of the drain, and deposit itself on the torque converter seal, eating it like aircraft stripper.

I hope the next generation of porsche engineers shoot for the moon and design a lightweight composite head stud, or possibly the perfect super polymer valve spring retainer, as the ones we have used for years, have failed so often and making them from plastic makes good sense. Maybe some plastic exhaust manifolds would be in order as well.

Very disappointing to say the least. I would expect these elementary design flaws from other manufacturers, but in the auto manufacturing business the motto of you get what you pay for is far from the truth.

Oh by the way if you think that this is an isolated incident, and that your car will not succumb to this failure, it is just a matter of time and or mileage that will let you experience the joy. What I am saying is if something has not been done to your car to alleviate the adhesive from failing, one of the fittings with the most tension on it will fail.

How about me as proof. My car has never been tracked. I started a thread yesterday on this forum in the 996TT section.

One instance isn't a trend.

Is your Turbo stock?

cdk4219

Please explain, with all of the wisdom that you have how on this earth the size of the turbo or the current wastegate setting on the car will have any effect on the deterioration and failure of poorly engineered cooling fittings.

Dock

Explain to me what asking you about your Turbo has to do with anything other than me wanting to know about your car?

And if the fittings were poorly engineered, most would have failed by now.

Carlo_Carrera

They are at least one hundred sighted tube fitting failures in threads on this board alone. The NHTSA has issued recalls for manufacturing problems with less failure rates than that.

Are you saying the NHTSA is issuing recalls for engineering successes?

drh

It is stock. Never been tracked and never had the **** run out of it. Never drag raced.

~48K miles and well maintained always.

Not trying to start anything, but I've stayed out of a lot of discussions here and when I see you posting, there is a sort of antagonistic tone to they way you write. Maybe you don't mean to come off that way. I prefer to offer the benefit of the doubt

WPOZZZ

My 02 has 20k on it and the engine is being pulled because my oil tank is leaking. Would it be wise to have the pipes pinned or welded while I'm in there?

Dock

And how many of those are repeats on other forums?

How many of those cars had been tracked prior to coolant pipe leaks?
