So, I'm just curious, what causes the coolant pipe failures that I read about in the 996 turbo? It appears that the pipes are metal, so is it the adhesive that holds them in place? Is the repair for them pinning and/or welding also?
coolant pipes are glued in, sometimes these dry up or fail depends though. I have a 15 year old Turbo that's been tracked in summer hard every year and never had a issue. I think some engines may vibrate or move around to much and put stress on it who knows.
The fitting are completely different then glued in pipes though, its a separate issue. While glued in these plastic fittings actaully crack and then leak. Same issue seen in the 955 Cayennes with its coolant pipe failures.
This set of stainless steel coolant pipes replaces the weak factory plastic units that are prone to failures.
This item is considered preventative maintenance and should be installed on all 997 Turbo (2007-2009), 997 GT2 (2008) and 997 GT2RS models. This part is not required or compatible with 996 Turbo models (which already have a metal tube).
A known weakness of the GT1 engine is that the coolant pipes (6-8 per engine) come unstuck from various housings and cause complete catastrophic coolant failures.

Agree!! I love mine. I have had one of my pipes pop loose. Re-bonded it and so far so good. Will have an engine out service soon and upgrade all the pipes and have them pinned. New coils, hoses and water pump etc....
If you want a heavier and even more dull steering feeling electronic awd car with a engine that is fitted with cost savings measures like plastic coolant fittings that crack with age, and pressed on cam sleeves that slip and the variable turbos don't hold up as well as the old ones that do not move. Then go ahead, get a 997.1 tt
yawn.
plastic coolant fittings. How many have failed? yes, I want a real number, not a "well duh, i read somewhere that its been a lot."
Proof that the VGT turbos don't hold up as well? Evidence? Facts?
Pressed on cam sleeves...yup, that sucks.
talking about sucking, lets talk about your cracking tailights, your 2nd gear popouts, your ancient pcm, 4 piston front calipers, etc etc.
Lest we forget about the 70bhp power increase, as well as torque bump, reduced turbo lag, etc etc.

I don't work for Porsche to keep track of numbers. I've seen personally the cracked fitting while the engine was out while it was getting repaired. Plastic ages and with the engine vibration its not if it will crack but when. Cracked tail light mounts tabs can happen, these are plastic like your coolant fittings, except these are easy fixed cheaply. I don't have and actually never came across one with 2nd gear pop out issue, I wouldn't have bought the car if it did. PCM? or PSM? The 996tt can easily be brought up to 600hp or more. The variable turbos are weaker do to the nature of how it works if you run a tune and push them have be know to implode. etc.. etc. nuff talk, you want to arrange a track date then you can show me how much better the 997tt is.
quad and jumper - Do the race in New Jersey and loser has to take Chris Christie out for dinner after you figure out a way to get him in your car.
I am in Toronto and he is in NJ, Mid Ohio is somewhere in between us, though we can to other tracks, I know NNJR comes up to CTMP but NJMP is not a HP track at so he would lose that advantage. A 997tt even driven by an amateur should leave my slightly modified 996tt in the dust as its so superior.
Had the opportunity to buy a 996 turbo with many modifications and ended up with a 3.6L N/A due to how much more I can actually use the power on local roads and tight twisters. I can push my N/A about 90% everywhere I go as where I couldn't do that with the turbo. I honestly felt as though I would never use the turbo to its potential and even the seller of the turbo car agreed with me.

I also currently have a 02 C4S. I agree, I can drive it full throttle with no thought not even worry about it coming out on you. Rain or Snow doesn't matter its almost a safe forgettable experience. You don't have to worry about having too much power or worry about having to manipulate the throttle to keep traction. You have to have keep it around 4000 rpm or more for it to be responsive. It can be more fun becuase of that just a whole lot slower.
