Smelling fumes in cab and hear a whistle led me to realize I had a broken turbo Y-pipe seeing the stainless steel "accordion" flex part covered in soot. when I removed the modded up-pipe (egr side), the end part of the turbo Y pipe fell out!

I can't seem to figure out how to remove and re-install a new Y-pipe. Without success, I tried to remove it from below.

Does it come out top side once the turbo is removed? if so how? it seems to be a puzzle.

 

The only way I could get it out was removing the turbo,and I spent more time figuring out how to get it out than it took to re-re the turbo.

 

I was wondering if the heat shield had anything to do with the secret of removal but since I'm at the point of removing the turbo, maybe the heat shield can stay in place and remove it once it's out of the way.


Thanks Tony.

 

The best way is remove the turbo and ****** the pipes out.

 

Yea you will have to remove the turbo. I removed that also about 2 months ago and I had to remove the turob.

 

As soon as the turbo was removed, the turbo inlet Y-pipe was easy pickin's. The heat shield didn't have to be messed with for its removal.
However the two 8mm bolts on the bracket were removed so I could get a little wiggle room to use a screwdriver and pry the marmon clamp (V-clamp) from the inlet side of the turbo attached to the Y-pipe.

The OEM Large Y-pipe is toast, it's completely broken in two at the flex joint. The small Y-pipe that goes to the egr cooler was thought to be where the broken flex was located but it turns out this modded pipe is holding together just fine.

There is a procedure involved in the removal of the small egr related y-pipe;
Remove the top 10mm bolts first THEN loosen the lower 10mm bolts connecting the exhaust manifold last. This will alleviate twisting forces upon the flex connector above. (reverse procedure for install)
This is for those with solid up-pipes or modded ones since there is no support from the egr cooler inlet.

 

When you install the new pipe do a little at each connection until tight.

 

I will, and thank you.

I am wondering if I have to do the same thing with the pedestal? also massaging it into place?
I think I should go around and torque down everything related to the turbo including the marmon bands a little at a time.

Also, I am realizing that the flex joints in the Y pipe have their purpose for heat expansion and contraction.

 

BTW, when the turbo is removed, the egr up-pipe can be still attached to the turbo "Y" pipe as a unit and lowered over the heat shield for reinstallation or initial removal.
