turbo to UP-PIPE question

[melmount]

On the back of the turbo to the babys butt(i guess that whats it being called) the piece the uppipes go to? What there for an exhaust seal?Is it just the clamp?Is there an Oring like on the front of the turbo to the intake runner tube? I assume the oring would melt back there? I am trying to find an exhaust leak and wondering what seals it on the back of the turbo?

just metal to metal contact thats why they use the style of clamps that they use.

The up pipes are usually the cause of the leak, just back of there.



I borrowed this photo from Southpaw's photobucket account. My apologies if this is not cool. It was previously posted in an unrelated thread here on the .org..

Here's another photo where you can see it from the back, above the engine on a van.

up pipe leak - Ford Truck Enthusiasts Forums

i replaced those about 3 months ago with ford gaskets. That means nothing, but i dont see any black marks from leaking now. But i guess it still could be.

[Rohan]

might not be there then, since you already took care of that issue. I is just the most common source for leaks so i figured I'd mention it. The only other place I can think of is manifold-to-up-pipe connection, or ebps tube.

i did replace the bolts to the manifold to up pipe connections. I was afraid to remove the manifolds themselves due to rusty bolts and maybe having to pull the motor to fix broken bolts in the heads.
How about where the intake bolts to the turbo(o ring?maybe air leaking out there??

I am wondering whether this so calledexhaust leak is a leak or the #8 cylinder cackle. I know i havce the cackle. I hear it plain as day at idle. I even have the xover tube. I still have it. I can live with it. But at low rpm maybe 1500, while in say 4th gear cruising i give i a little throttle and hear this leak, (sounds to melike an exhaust leak but i amwondering if its the injector cackling just sounding different. I dont really hear the injector at this time? Maybe its just sounding different?
