Sorry, I'm getting frustrated.
This is a continuation of http://vwdiesel.net/phpBB/viewtopic.php?t=17001

I Was told that the wastegate is F%$#ed, lack of boost would indicate stuck open since the BOV is blocked off.

Depends on the turbo.

On the kkk turbos there is a screw in the middle of the waste gate you can clamp down to raise boost but on a T3.. If it's stuck open your going to need to take it apart I believe.

take the dp off (lots of penetrant) and give the wastegate dump valve some good taps to get it to close.  there is probably a good amount of buildup around it though...  maybe torch it to burn it off?

you need to take it apart and lap or clean the sealing surface.

I plugged it with JB weld. I took some pictures of that i think on my much anticipated 1.6td build thread

I plugged the 90 degree fitting that connects to the rubber line.
