Gas Recirculation Valve (egr Valve) Problems of Porsche 911 Gt3

On very hot day, over 100 degrees f, after having just exited a freeway onto a city street, while accelerating from red light, a glued-in water coolant pipe/tube popped out from its cast housing, causing catastrophic loss of all cooling fluids which spilled onto the roadway, immediate increase in engine temperature from 185 to over 260 degrees f, and loss of power. Car needed to be towed to repair shop.

"permanent" coolant hose attachment failed; it came loose from its mounting in the engine resulting in coolant sprayed onto tire, with complete loss of control during a turn , including 270 degree spin, and leaving roadway; fortunately no other vehicles were nearby, so a collision was avoided. Apparently, this is not an unusual failure with the gt3 engine. Note: this was not a coolant hose or hose clamp failure, this was a structural failure of a permanent engine component to which the coolant hose mounts. Given the serious safety issues at stake, both to the driver of the vehicle and those also using the roadway near the affected vehicle, it should, in my opinion, be addressed with a safety recall as soon as possible. This is a design defect that is undetectable until the part fails, with potential loss of life and substantial property damage.

Went to streets of willow driving event. During 3rd run session I noticed steam coming from behind as I was taking a 180 degree turn. I immediately stopped the car when it was safe to do so and shut the engine off. Steam kept billowing and the car seems to have lost all it's coolant in a few seconds. 5(!) cars behind me all spun in the 180 degree turn because of this failure. Fortunately none of them crashed. After examination it turns out one of the coolant fittings that Porsche glued into the motor block with epoxy had popped out. This appears to be a very common problem with all of these gt engines. Not only is this dangerous (every gt2/3 on the road is a ticking time bomb, street or track) but it is also costly to have it fixed properly. Needless to say I had my car towed to a shop that is very familiar with this problem to get it fixed right. The solution is to weld these fittings into the motor block. There are 8 of them and the engine needs to come out of the car, the fittings all removed and cleaned from the epoxy before they can be carefully welded back into place again. It is the only valid fix. I have a receipt showing $2750 to have this done. I feel this was my only course of action to make the car safe to drive again and I think Porsche should recognize there is a problem there and reimburse owners that had this done and offer it under a recall to owners that still need to get this done.

I was driving at miller motorsports in tooele utah in drivers education event when my engine temperature gauge started to increase from 180 degrees up past 200 degrees. As the temperature gauge went to 250 degrees, a coolant failure light came on. I pulled off the track and shut down the car within 2 minutes of the failure light and I had to be towed off the miller motorsports track. I had lost all of my coolant from the car. The next morning (Sunday) I took a rental car back to miller motorsports along with 9 gallons of distilled water. I poured 2 gallons of distilled water into the car, and then started it. About seven minutes later, water started spurting from an aluminum coolant line attachment that had come unglued. This aluminum attachment was in a place on the top of the engine that was readily determinable as the water was shooting straight up from where the fitting had come unglued and slipped off. I do not currently know whether I got the car stopped in time for the engine to be ok. I am afraid to drive it before I get all of the aluminum fittings reglued or welded. Because this happened on the top of the engine, the coolant did not create a situation that was a safety risk to me, but if it had been a diffferent aluminum coolant attachment that let loose, I could have crashed at 115 mph due to coolant on the tires or someone behind me could have crashed. The miller motorsport personnel said they noticed a plume of steam at the end of the front straight. At the end of the front straight, I had slowed to 115 mph. I am the original purchaser of this car and did not think I was at risk for this type of safety issue on a car that is not driven in stop and go traffic. It also only has a little over 28,000 miles.
