JB weld will definetly work if prepared properly prior to installing the JB weld.My coolant pipes are welded now but i did at one time have to JB weld one in because of a time crunch situation and it lasted quite a while and had no signs of letting go when i did get around to welding it .It actually was a giant ***** to get off lol.
I would guess that if you haven't had the failure yet, like me, that some JB in combination with the factory stuff gives some pretty good support. But making one point strong just makes a blow out somewhere else more likely.

Well I will say the 4500 included more than just welding. Literally every hose, and gasket, and o-ring that was readilly accessable was replaced. I needed the piece of mind because I drive about 90 miles a day in my baby, and didn't want something else to fail down the road. Oh and it also included the GT2 conversion as well.

I was driving along the highway at 65mph and I noticed that the temperature gauge started increasing and that there was steam bellowing out of the engine. Pulled off highway and coolant was pouring out from the left rear engine compartment - Had car towed home to inspect and upon removing the airbox it became very apparent that it was the dreaded epoxy coolant pipe failure on the pipe just below the alternator.
I know the long term solution is to have the pipes welded or pinned but does anyone have experience / write up on using JB weld to solidify the pipe? It seems like it could be a simple fix for the interm until I do a clutch + gt2 slave later this year.
Any info?

My fitting just let go today on my silver turbo on the last run of the day at auto cross at the tire rack .. 12 of us cleaning the track for an hour. Just fixed it with jb weld.. Grind with a dremmel , chemical clean , apply to both sides , let sit for at least 48 hours. At least I got ftd. My black turbo let go at ginger man raceway last summer. It was the one under the alternator for both.

Hopefully you get it resolved quick and back out to enjoying some spirited driving.
Plus one on this one.
Two questions for the JB weld fix - Does using this fix inhibit the ability to weld the pipe in at a later time? How would a shop weld this after the JB weld is there? As for applying the JB weld are you coating the outside of the pipe and inserting it in or are you inserting the pipe and coating around the pipe with it? Combination of both?

I got really lucky with my new 996tt. A coolant hose let go while the car was on a test drive(not me driving). It turned out my Audi mechanic did the welding and the bill was over $3000 for all the hoses, I believe there are 8?? and a few other things were done while the engine was out

Hmm it happened to both of my turbos under the alternator also.

I just looked at my invoice and the total was $1589 for the R&I of the motor and then $1000 for the welding of all 8 coolant fittings. The $1000 included the removal of all the fittings, cleaning and preparation, and the actual welding done by an FAA certified aircraft welder. There is a good bit of engine disassembly to remove all the fitting as you can see in the attached pictures. So you're looking at $2600 give or take.... If someone is quoting you $5K then they are bending you over.....

steeze,
Welcome! sorry to hear of your woes. There are a few of us here in the valley in the PCA & on this forum with 6TTs. None of the the other guys that hang nor I have had a failure with the coolant pipes. We are all active with our cars (I've had mine many years), perform a lot of our own maintenance.
What part of the Valley you in?
