Default Pinning/welding cooling hoses, 997 gt3 problem only?

Folks, I'm contemplating a 996 GT3 (again). There's one for sale out of state. I inquired about maintenance on the car, etc, and also about pinning the coolant hoses. The response back to me was basically, "the hoses have not been pinned as it is a 997 GT3 issue only." This struck me as weird since everything I've read indicate that this was a 996 problem.

Am I missing something here?

FYI, the place listing/selling the car is a very well respected shop here on RL. So this is confusing me even more.

It's both.

It's a great car. Fantastic. But ... it has a couple of issues as do the 997.1 and 997.2.

The way I look at it the maintenance and mods to address the issues is far less than the outlay (and depreciation) for a newer car with all the nannies.

Happens to all GT1 block motors, sometimes this does...

Ugh, this makes me leary about this shop/dealer selling the car! Especially says in the email that it's only a problem on 997 GT3s. I guess I'll continue looking.

Thanks!

"WHEN" I buy another Mezger powered car, it will have all this done before hand. Still beyond disappointed in Porsche over this epoxy pipe nonsense.

2001-2007- Formal investigation now as posted elsewhere. File those complaints if you had a failure/repair.

The correct fix is to weld. Yeah - it costs more. That's typical with doing things right. Pins are a bandaid.

As mentioned above, it affects 996 and 997.1. We'll see if the epoxy on the 997.2 was truly fixed, as these cars age.

Had mine welded recently, and submitted a complaint to NHTSA. The pin approach seems to work as well, unless Sharky et al are lying to us (which I doubt). I just went with welding because it seemed to be the more elegant fix.

I have welded an awful lot of these water pipe sets. Never had to do a failed one but around 75% of the ones I have done had at least one that did not look too good and was close to failure. I disassemble and clean every trace of adhesive off the tube and the socket. It is very easy to see which ones were going to stay put and which ones were close to coming apart. A few tracks around here mandate some form of repair. Some people pin them, I have no issue with pinning just wonder where the swarf goes from the hole drilling. There would not be much, but even a little can add to the waterpump's marginal seals issues.

As noted above, all GT1 motors can have this issue. Have done 997's and they look to have the same adhesive failure patterns as the 996's and turbo. Just not as many as the parts are newer. Never really put a statistical count so I don't know where things might improve year wise on 997's.

It is essential that you report the preventive repair for safety. File complaints. welding is proper repair.

Hi,

I am with a law firm that is looking into reports of catastrophic coolant leakage in Porsche 911s, similar to what you have been discussing. If you have experienced this issue or are interested in the investigation, please feel free to email me at emo@girardgibbs.com, or give me a call at (866) 981-4800. You can also visit our website http://www.girardgibbs.com/porsche91...investigation/.

Thanks,
Ellen

seller is wrong.
6 has more pinning issues than 7, mainly due to age.
i know i am victim.... like a top down T9 or laguna... the wall gods were nice to me.

This just happened to a fellow-Rennlister this past weekend with his 6 "3" on the track... The epoxy broke free on one of the fitting on top of the engine, spilling coolant on the track. Luckily, it drained through the center of the car and not on a tire at speed. It did end his DE weekend though...

Due to this "first hand" knowledge, I'm am more seriously considering welding the lines on my 6 "3" during the winter off-season.

One of my fittings came loose, but we caught it with a visual inspection just before it burst.

We welded that fitting. The remaining 5 will still need welding, but I have been waiting to see if there is a resolution from Porsche first.
