Sorry, I'm getting frustrated.

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

Remove the turbo and fix it maybe?

sounds like the screw on the wastegate needs to be screwed down???

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.
