91 350 with a ats turbo ,Igot the two bolts on back of the throat off and the down tube,how do you disconnect the turbo from the manifold pipe? is there a hidden bolt or something ?
Its leaking oil under the turbo somewhere and I seen a post of the same problem that <font color="red"> cdnsarguy </font> described but did not say what the cure was so if you could Pm me on how to fix I'd be extremely happy

You might need to put one of the bolts back in that holds the turbo to the mount and start soaking the slip-fit joint in penetrating oil. Those things are frustrating. The only way I could get mine off was by reversing the crossover pipe and bolting it on to the bottom of the y-pipe, then using it as a lever by kicking it back and forth until the up-pipe broke loose in the turbo inlet.
Your turbo drain grommet is probably leaking. ATS no longer sells the grommet for the non-wastegated turbos.
I am not sure, but I think he's talking about the older non-wastegated ATS that is a slip-fit joint at the up-pipe into the turbo.

So it has slip fit on both sides of the exhaust at the turbo then?
what a pain in the .....

You don't wanna know. I have had 2 of those systems and have spent several full DAYS trying to separate those pipes from the turbos. Compare that to the wastegated ATS that I have now, which took me a couple hours to pull and put back on start to finish this afternoon...
The older square-boxed 088 ATS non-wastegated sits along the back of the engine parallel to the firewall, and has a one piece y-pipe/up-pipe and slip fit joints into the hot side of the turbo AND the downpipe.

The 093 ATS w/ wastegate and s-shaped airbox sits at a slant across the engine and has separate y-pipe and up-pipes w/ a slip fit between them. The up-pipe then bolts to the turbo at the 4 bolt flange, and has a slip fit at the downpipe.

Course, there's also the even older 085 system, which you don't see too often, but he could have that too.
