EGR stall test question

[zukitrek]

Good mornig sir. This is the nipple i tried inserting on the ports. As you can see is about 3/16 of an inch.    
This nipple did fit in the hole. The other nipple I mentioned that did not fit was a little bit bigger. Anyways this did not help much as the blockage was worst. Here are the other pics of the drillings sealed with the screws and JB Weld.        

Now to work on that tranny. did you get to see my last post on the late shifting thread?

Ragards!!
