86k miles. After doing the work myself and seeing with my own eyes how the fittings are installed, I think it's like playing Russian Roulette after you tune your car and install turbos. You will be creating more heat which is what causes the pop out. There are many threads and opinions on this, but until it happens to YOU, it's hard to swallow! You could do the pinning for less than 50 dollars if you have a drill, drill bits, and just a few other small items, over a single weekend. That's all I am saying on this matter. Good luck.

 

Thanks for the info.
I'm all for preventative maintenance.
Is there a diy online for the pinning?
I wonder how you keep metal chips out of the pipe inside?
Last month I put in a water pump which was preventative only.
The original water pump looked fine when I took it out.

 

There's a fantastic DIY on here. I will post when I get time to search for it

 

This is the one I used.

Awesome diy write up!
Thanks!

I will need to review the link in detail.

 

I'm sure you have read the NHTSA report shown below.
I wonder what the real percentage of coolant failures are compared to the total affected population. Also there is the concern of adding extra heat from the K16 turbos and tune. Since I only drive about 2-3 thousand miles a year in my 996T I may risk it and not do the pinning. Maybe I will change my mind later.

"The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).

NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.

There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

"A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted. Accordingly, this investigation is closed. The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances," NHTSA said.

Summary:
On April 26, 2013, the Office of Defects Investigation (ODI) opened PE13-009 to investigate 10 complaints alleging incidents of sudden coolant loss while traveling on public roadways in certain model year (MY) 2001 through 2007 Porsche 911 vehicles. The complaints alleged that pipe ends joined by epoxy to certain cooling system components may fail suddenly and separate, resulting in large volumes of coolant leakage. The investigation was opened to assess evidence of a design or manufacturing defect in the coolant pipe fittings and any related safety consequences. In response to ODI?s Information Request letter, Porsche identified a manufacturing quality issue with the supplier?s application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008). ODI?s analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier. Most of the leak complaints reviewed by ODI did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked. There were no crashes or injuries reported to be related to the alleged defect in any of the subject vehicles. ODI identified two allegations that coolant leakage resulted in loss of control incidents, but neither involved vehicles affected by the assembly process quality issue. A third loss of control allegation involving a vehicle built during the period affected by the supplier process concern is not counted since ODI was unable to contact the owner to confirm the incident. See the full closing resume in the document file for PE13-009 for additional information about the subject cooling system and ODI?s analysis of field data related to the alleged defect. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted. Accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances."

Alexander Ehrath Wait what? Did they read any of those complaints??? Most of them (including mine) had complete coolant loss! How on earth they could only look at 10 and ignore the rest is beyond me. Come on Porsche, or should I say Porsche LAWYERS, really??? How many more have to lose their cars or get hurt before they admit there is a problem? The report even states they used inferior glue. Huh? Porsche used GLUE on heat cycled under pressure parts? What a concept. So, so disappointed

That B.S. report is why I ended the above post with "that's all I'm saying on this matter". We have had plenty of discussions on this topic. I have exposed you, you choose the risk. That's all...I did my job!

 

Thanks for giving me a "heads up".

 

I just came back from my first test drive and improvements going from just a tune/exhaust to the K16 billets, 5 bar, and tune are huge!
Below are the improvements:
*much less turbo lag
*significant and even increase in power
*boost comes on quicker
*it pulls to redline better.
*the tune itself is better and my car starts off from a dead stop better.
*more instant throttle power than before.
*car still drives as smooth as stock.

Mark,
Thanks again!
It is really an awesome improvement!

Jim

 

Hey Markski,

Given the late spring this year in Chicago, is the spring special still available to 6speed members? How about an installed price including the 3.5 inch intercoolers?

 

Give me a call at 773-980-6550 we can discuss it.
Best
Markski

 

Is the power difference that noticeable?
I already bought this package but only have exhaust/tune loaded.
I'm finishing up suspension stuff right now and will have k16 billet/injectors/retune soon. I'm just wondering how much a difference you can feel.
Thanks.

 

Currently I have the 5 bar instead of the injectors and it is a significant improvement as I mentioned before. I decided to wait and have the injectors done at the same time I get the updated clutch early next year.

 

Oh yeah, you will be able to tell by the smile on your face

 

I was grinning from ear to ear after my first pull with the K16 billets.
