As Dan was saying on the other thread welding is another way to do it but a bigger modification with more complexity and potential problems in the fix itself. Prior to the machined fittings being sold on Ebay ($200 as posted in these threads) we believed trying to weld the existing tubes to the cast piece was less than ideal. This kit might be a better solution; we have ordered one and do plan to see how well it works on a future build. It looks like it is not a complete kit though from the auction descriptions, we will determine this once we have seen and tested it.
To weld this will probably add 5-6 hours of labor (maybe more) to further disassemble / clean everything and weld, plus the ~$200 in parts etc. There is a greater risk involved in ruining the cast pieces and there's always the possibility the weld will crack later too.

had something like this on the 993 case of my 3.8L GT2R car....we solved it with a backyard stepped double male AN compression fitting in several areas and never looked back...any thoughts on this Alex or Dan?

AND the Safety Chair at a PCA Chapter asked me if I was an Engineer & asked me how I could make the claim that they will all fail. I've decided I don't have to be an Engineer but I'm sure they will all fail.
held together with spit and glue. PCA will not take a position. Everyone watch out for the falling off exhausts also.

The NHTSA has opened investigations from more limited complaints than it seems are being volunteered about these fittings. They only respond to issues that can become safety hazards. Rapidly losing coolant on a curve, or ramp, is a concern. No?

If you own a car with the GT1 engine and it has failed this way, give them your VIN. If you won't do it for your own sake, please do it for the rest of us. Otherwise, it looks like we're just mice.

Dear Nugget: My name is {redacted}, I am an investigator with the National Highway Traffic Safety Administration of the US Department of Transportation. I am interested in the report you filed with us regarding your 2007 Porsche 911 GT3 coolant loss. Can you give me some more details about what happened when the problem occurred? How long have you owned the vehicle and when did this problem start to show up? Do you use the car in any racing or club events? Can you please e-mail/send/fax copies of any repair orders you have related to this problem? Is there anything else you can tell me would be helpful in understanding the problem you experienced?
