I got an exhaust leak

[killjoy]

I had this exhaust leak.  I found out I had a broken bolt in the head.  I took off the manifold and turbo in one piece, and all the hot side, drilled a hole, easyoutted the bolt, put it all back together and I still have an exhaust leak somewhere.  I retightened the turbo outlet 5 bolts, flange 4 bolts, and manifold 8 bolts.  I even tightened the o2 sensor.  Its still there!!  Where or what next?

Sounds stupid but did you replace any necessary gaskets?  I know when i had an exhaust leak in my headers I fixed it but tried to use the old gasket and it was leaking from there.
