As some of you know I pulled the older style ATS turbo off my truck in favor of a factory unit off of a '94. I have been plagued by exhaust leaks at the y-pipe to up-pipe union.
The y-pipe I have fits very loosely into the up-pipe, which I noticed when I test-fitted them before they went on the truck. The ends of neither look damaged, so I wonder how tight of a fit it's supposed to be. The gap I have is big, 1/8" or so between the y-pipe and up-pipe. The y-pipe obviously can't slide further up into the up-pipe because its located by the studs on the manifold. I have tried every sealant I can find and nothing will stand the heat for very long. Perhaps that's due to how much I have had to use to fill the gap.
RLDSL is sending me another y-pipe, so I'll compare that to mine.
Any other ideas? Any feedback on how tight those pipes should be when slid together?
