Guys- all you can do is make a complaint with NHTSA. Fix your fittings and drive safe. Not much else now- There was a law firm in one of the threads that was interested in starting a suit. Don't hang heavy stuff on your key chains !!

Just poured through the entirety of this thread. Short of scraping and analyzing the data it appears as if the issue is generally isolated to 996 and 997.1 GT3's.
My local mechanic informed me last week that in order to drive in any PCA events, all 997 GT3's irregardless of generation or year must be pinned or welded.
I don't intend to race PCA, but I am concerned about this being an issue in my '11 RS. I'd hate to send a friend into the wall during an open lapping session.
The Question:
Does anyone know what changed b/w .1 and .2 GT3's that has seemingly decreased or removed the likelihood of the issue? By now, there should be loads of .2's with >10-15K miles on them that should have "blown up" on track and yet, very few reports of such behaviour on this thread.
Cheers,

It's a ticking time bomb. As the glue gets older and has less strength, it will go.

I don't believe all PCA regions require pinned/welded fittings on all Mezger engine cars. My local region, OVR, has stated that 997.1 and earlier cars need to be pinned/welded or have no antifreeze. I did not have to do anything to my 2010 GT3. However, I will have the fittings welded.
Supposedly Porsche changed the glue to a more robust product. I can't imagine that there isn't a product there that would handle the task. If Figg could epoxy the Linn Cove Viaduct surely a water pipe could be successfully glued into an engine.

Very few regions have taken a position. If your car's fittings are not done and come loose on track and others wreck behind you. the ethical question is " are you responsible for the incident knowing there was a fix and potential danger to yourself and others. Many threads on this subject. I personally fixed mine so I wasn't ever put in that particular situation. **** happpens- fixing the fittings makes it one less. I could not with a clear conscience go back on track without fixing them. I have a problem when I'm on track knowing some have not fixed them. My choice to drive or not to drive. tough at times.

Thank you for the pointer. I'm using WW anyhow... Maybe this needs to be added to tech form for pds and tt.
Btw you may want to fix the 991 reference as they do not use the same engine block. It's really: 996 gt3, 996 turbo/gt2, 997.1 gt3/rs, 997.1 turbo/gt2, 997.2 gt3/rs and not sure on .2 gt2
11.0.25 All water-cooled vehicles entered in racing events may use only pure water in the cooling system (Redline Water Wetter allowed). Use of ethylene glycol (antifreeze) is prohibited. Antifreeze is allowed only in vehicles entered in PDS or Time Attack events, however, 996, 997, and 991 GT2, GT3, and Turbo models using the GT1 derived engine may use Antifreeze if the manifold fittings on the cooling system have been welded or pinned to reduce the chance of fitting failure. These cars have a history of fitting failure when on track and can dump coolant on the racing surface requiring clean up and causing significant delays. If the manifolds are not pinned or welded, then the Antifreeze must be removed and replaced with pure water (Redline Water Wetter allowed). Please contact the Competition Director for more detailed information.

2004 996GT3, 51k miles, blew hose top front of engine (don't know which exactly yet).
Blew at the the Nurburgring last Thursday (4th Jully 2014) coming into Dottinger Hohe, on a straight and off line, no-one behind.
Hot day and foot to floor out of Galgenkopf, could have bee so much worse. No warning lights and car did not overheat.

You're not in Canada so you should be ok.
