You're welcome. Dan, I hope you're not feeling too broken this morning! hehehehe!!
Migue, I will send you the spare valve so you can take it from here. I have your contact info.
I'd be interested to see what others would have for this topic too.

I was a little under the weather, until about 11AM 
Sorry guys, i get lost after the 
so, bumping an old thread:
there was talk of removing the piece that moves the valve, but was it ultimately determined it would be best/easiest to just plate the thing off and put the valve back on so the ecu thinks its still moving the valve, so no CEL...right?

from what i'm getting from reading this thread... The no-CEL wasn't confirmed after driving the car for more than 50 miles. But the block did work, however it might make the engine block hotter?
The exhaust gas is routed along side a coolant channel in the head. While blocking it from the EGR side will eliminate a good deal of heat from your intake air in #4 it will still transfer heat to the head. the #4 exhaust port has a slit cut into it, that leads to the hole that goes through the head. I have taken quite a few pics of this, and will include it in my final writeup(whenever that happens, I can't even finish the car
) If you can block it from the exhaust side you will definitely get a decrease in head temperature. I was thinking about getting a piece of rod with the same OD as the hole and bending the end to fit in the channel. This would block the exhaust from the exhaust side of the passageway instead of the intake side.
I did find out more information during my research this week though. The EGR valve is checked by the MAP sensor. Apparently the EGR opening changes the vacuum pressure slightly, and if the MAP sensor does not see this change it will throw a CEL. I am not sure how accurate this is, but it makes sense to me. something to keep in mind when testing this anyway.
