y-pipe problem (pics)

ok, i just changed the rear turbo on this car, i removed all the assembly as i was suppose to change the primary turbo also.

everything bolted back up together really well until i got to the y-pipe. here is what it looks like.

no matter how much i try to pry it, there is no way this is going to line up right.

anyone ever had that happen? I am kind of out of ideas.

thanks a lot.

Loosen the peices that go to the turbos, then hand fit and tighten the bolts for the y-pipe. Did you remove all the pipes beforehand and check if they were ok? The o-ring on that rear turbo side should have vasaline or similar lube to keep it from coming out of the groove and/or pinching. If it's not on their snug it should be replaced. I can't remember if you can do only one bolt on each turbo inlet (like drivers side front/rear then passeger side front/rear) but if you can that may help. Are you shure you aligned the turbo assembly ok?

Did you "clock" the turbo housing back exactly where it was ?

the bolts on the rear turbo are not even thight, if i pry enough to be able to align the holes on the primary turbo, the o-ring pops off...

I had the same problem when I took my turbos apart. To line them up again I just tapped the compressor housing with a rubber mallet.

i think your bearing housing is misaligned with the turbine housing or bearing housing with compression housing or even both sides might be misaligned, all the bolts need to be on tight before you put the y-pipe back on.

Well case is solved guys, i had an other set of turbos lying around so i made sure the y-pipe fit nice and realised that the angle of the turbos were off a little so that really was my problem.

luckily, i was able to pry them without having to remove the whole assembly again.

thanks everyone.
