Look at the Y bolted to the rear of the passenger side manifold, both the manifold and cross over pipe connections.
Then look at the slip joint in the turbo up pipe.
Also look at the driver side manifold to cross over connection.
Also the base of the turbo where the up pipe bolts on.
And finally check the manifold to head connections on both sides.
A leak before the turbo is usually easy to spot if you look good, black soot on everything close to it.
On the charge air side, things get harder, but you will usually see motor oil in that area from the CDR gasses.
The exhaust connections do not have gaskets on the crossover or Y connections.
The charge air side has O rings in the turbo and manifold connections.
When I was cranking my boost up, I had bad leaks at the crossover and Y to manifold connections.
I went to NAPA and looked through all of the exhaust gaskets till I found a gasket with a steel stiffener the same size as the crossover pipe ID and the two bolts for the clamp almost fit in the two holes in the gasket.
A little work with a drill press enlongated the holes till it fit the bolts perfectly.
Then I used "Permatex Copper Spray Gasket Maker" to coat both sides of the gasket before I installed them.
One in the manifold to Y joint, one in both ends of the cross over pipe joints.
I am running mid 20's for boost with no leaks now.

Yeah, I was wondering if Ford used the flange type with no gasket or with one. I can only hear it when there is a load on the engine, so finding it at idle is a pain. I can't here it once the turbo spools, so I'm thinking it is on the exhaust side. If it is leaking from where the left manifold and crossover pipe connect how do I get it to stop? That's where I think it is since it's the only spot with any soot.
