EGR Blockoff Plate
The AWD has some rough idle so being it has 105K. I figured it was time to blockoff the EGR Valve. There are other vfaqs on this also.
 |
Here is the EGR Valve on the car. If you look above, you can see where I pulled the ISC Motor for testing. Remove the vacuum lines from the valve and mark them. |
 |
With a 12mm socket, remove the two bolts and the valve should come off. The left arrow shows the vacuum lines. |
 |
Here is the EGR valve and the metal gasket off of
the car.
|
 |
Scribe a line around the gasket onto a piece of metal.
I choose to use metal left over from hacking the airbox. It seems sturdy
enough.
|
 |
Here is the line I traced. I used a Dremel to cut
around the mark.
|
 |
Then took a sanding stone to remove rough or jagged
edges.
|
 |
I scribed lines for the 12mm bolts to attach it back to the intake. The pictures below show where I drilled the hole out and widened it with a dremel with gasket on. This enabled me to be more precise. |
 |
 |
 |
I added RTV sealant to the valve before putting the
plate on.

 |
Here is a pic with the plate back on and last the gasket. I added more RTV to the side that meets the intake manifold. That's it! Bolt it back on and add the vacuum lines back. |
