Engine Cooling System problems of the 2004 Porsche 911

My gt3 has cooling pipe on the engine external to the block. I have read this is a systemic issue with the engine used in gt3 and turbos (metzger motor). A fitting comes loose due to adhesive failure resulting I loss of all or most of the coolant fluid. The repair requires engine removal and repair of the fittings. There is some issue as to the proper or best repair approach. What is know is that the adhesive failure is almost sure to occur. I have been lucky as I have few miles on my vehicle and have not yet experienced this failure, but very concerned this will occur and the sudden loss of coolant fluid will most like result in a spinout or crash. Even if no accident were to result, I am out of normal warranty, this failure will set me back $1500-2000. I have followed reports of the numerous failures of these fittings on 6speedonline. Com. As I have not yet had a failure, I still want to register my concern should there be a NHTSA directed recall to Porsche.

The event happened in 2008. Purchased Porsche gt 3 from Porsche dealer in 2006. Accelerating onto a limited access highway from an entrance ramp the car made a violent fishtail movement in a counterclocwise direction causing a 180 deg. Spin. I tried to correct but no response and then applied brakes heavely but car continued its movement eventually hitting a concrete barrier in the right rear. The car had to be towed and eventually totaled by the insurance company. At the impact site I did notice fluid on the road and also back up the road. Since my wife was injured and needed to be taken to the hospital, I was more focused on tending to her but as I look back and also reading about the collant problems this car is having I would not be surprised if this car had a discharge of cooling fluid. As a side note, I do hold a competition drivers license with the scca and have competed for over 30 years and have owned Porsches for over 40 years. I presently own another 2004 gt 3 and very concerned about this problem. ## VIN failed ##.

The above car has a factory water cooling system that involves aluminum piping that is epoxied into the block after approximately 24 months of use the epoxy fails and all the coolant is evacuated from the system all over the engine and the ground the motor could seize and the coolant on the road in that volume creates a dangerous situation for other drivers. The epoxy fix offered by Porsche failed 3 times for me (twice more subsequently)until I had a shop weld the aluminum pipes to the block. ## VIN failed ##.
