Y-bridge

roughly how long does it take to remove the Y-bridge and are there any special tricks to getting it out like some fancy rubber ratchet or anything? I did my FPR and while I was in there I didnt really take a look to see how bad it would be. I bought the All Season EGR delete with Y-bridge and Im thinking of diving in on Friday.

If youve never done this before it can deff be time consuming. By the 3rd time i finally replaced mine with a profab kit but i also had my turbo out at the same time so it took a little less time cause there was more room for your hands. Mines an 07 lbz so its a little diff but not to much, i ended up tapeing two 10mm wrenchs together and flattening out the closed end to get the front two and i also made all the bottoms studs and used a magnet to get the nuts on them. Seemed to be alot easier. Just take your time and youll be alright. Id say close to 4 hours or so if i remember??

I believe it took me around three hours to get mine in there. Not bad, just time consuming. You can help yourself out alot by starting the 4 nuts on bottom studs before you drop the y bridge in. With having the egr cooler out of the way, I was able to get get a wrench and my hand in from the back passenger side, next to the turbo. But now I just saw you have a 2008 so may be a little different. Nevertheless, good luck and have fun.

I know the FPR wasnt a whole lot of fun, the biggest pain there was getting the intake elbow back into the Y-bridge, I probably spent over an hour alone on that.

Its a pain. I had to loosen my turbo and tilt it back to get my y-bridge out. To loosen the turbo bolts I used a swivel socket. I believe its 17mm

Good luck.

At least I have access to a full auto shop and everything in it, I should be able to figure this out.

Well, I got it done, took most of the afternoon at the shop. There is one bolt that does not clear the turbo so I ended up cutting the head off and backing the rest out with pliers, I replaced it with an allen head capscrew that would clear. Other than that, all the fuel and coolant lines in the valley need to be disconnected and swung out of the way. I would not do this in your garage unless you have a lot of tools. I was in a full auto shop and still had to get creative a few times.

A good set of flex wreches and a large array of socket in the 10-15mm range in 1/4-1/2" drive, some various screw drivers, and if the EGR is coming out, a 5' pry bar some wood a case of beer, box of bandaids and a good buddy to hold you back so you dont take the bar to the headlights. Those up-pipe bolts are very stubborn and you dont have much room to move.
