Removing twin scroll flapper AND re-installing it
OK, so I have a few cracks in my turbo manifold, one of them is right near the twin scroll flapper. I want to pull the flapper out so that it can be easily welded BUT i want to be able to re-install the flapper. I've read all the posts on how to remove the flapper, but these are all permenant and I would really like to fiddle with it when i put in my BNR, just to see.
Any body have any ideas??
Please don't make this a twin scroll good/bad post as its been done. (and done and done and done)
Thanks
Augie

Not easy...
You either gotta cut the flapper off or break the braze at the joint.
No real nice way to do this.
Why you want to put it back?
Just buy another use manifold, since they are a dime a dozen?

Interesting that you think that I would break them. as they came out without a fuss. Lots of PB blaster, but not much trouble. One of the studs had a thread missing, so I figured I'd pull it and replace it as I wouldn't trust the thing otherwise. I figured I would just pull the other 3 as well. The only one that gave me any trouble was the one with part of the thread missing. I had to get a little creative but they are all out and reusable, execpt the one of course.
That being said. Where do the cracks tend to happen on these things, all of mine are on the turbo flange side, and the engine side as NO cracks at all. For some reason I thought this was the other way around. I'm alittle worried as one of the cracks is quite big. I slipped my spare turbo (new BNR ) over the thing and it looks like it should work but I guess I'll find out. I'm going to have it welded and then check.

cracks always happen in the middle. Looking at the 4 studs on the turbo side, the crack will always be adjacent to the upper righthand one, there is a little pocket where the manifold curves and right down in there will always be a crack that extends around to the back.
IF any cracks extend onto the turbo mating flange it is not a good idea to try and fix it, I'd suggest just getting another one with less mileage. Even low mile manifolds usually have the small crack in the middle, though.
