I've seen alot of posts regarding broken EGR pipes so I thought I'd just make a seperat post. I was able to remove mine, braze it and reinstall it in under 3 hrs total. Alot of that time was some thinking, a trip to home depot for a small oxygen tank, brazing and testing for leaks.
Here is how you do it:
Take a 12mm open/closed faced wrench and tie a 3'-4'string or wire to it. Trust me. Just do it. After you drop the wrench for the 4th time you will know why. You will have to do this blindly. with your hand follow the EGR pipe down until you feel the bracket that connects it to the engine. There is one screw. there is VERY little room and you'll have to reall squeeze to get there. now you know where it is. Now take the wrench to it. put the closed end of the wrench over the bolt and carefully remove your hand leaving the wrench over the bolt. You'll neeed some leverage to break it loose initially. I used another wrench to put the open end of one into the closed end of the other to get more leverage. once you break it loose it's just patience. This bolt alone will run about 30-45 minutes. Once it is off, disconnect the two ends and pull it out the top of the engine.
Once out, I cleaned and preped the TWO LARGE cracks for welding/brazing. I had bought a small Mapp gas and Oxygen set from Home Depot for about $50.00 some months ago and now it was time to get my money's worth from it. If you don't have one of these things, they are very cool and inexpensive. They get VERY HOT You can actually weld with them. I used a Flux coated Bronze rod and brazed the cracks. I put it into water closed off one end with my hand and blew into it to check for leaks. There were none so I reinstalled. I would NOT recommend using JB Weld. It is great for hi-temp but not for vibration.
The only issue is that I have been unable to reconnect the center bolt. I thought that might happen. I'll try again later but I really don't think it is that big of a deal. I have also heard that you can reach the bolt from the bottom of the car as well.
Now that I have done it, it would probibly only take about an hour to do.
How did it work, you might ask. G R E A T! My car is back to sounding like a Lexus rather than a 1973 Ford LTD.
It feels good to finally make a worth while contribution to this great site.
