EGR Block off the CORRECT way

For those of you that want to have both options, EGR system and block off, this will give you both options with a quick swap back and forth.

Materials needed:
Tap and die set
One small bolt, I'd suggest using a very small hex head bolt
Drill
Grinder (bench or powertool)
Thin piece of aluminum or steel (Id suggest aluminum but I used steel)

First off locate your EGR Valve, directly behind your distributor, next to your fuel rail. There is one vacuum line connected, remove that line and set aside.
Remove the two nuts that hold the valve in place, the studs may come out too, not a big deal, just set those aside.
Remove the valve and use the base of it, or the gasket, as a template to make your block off plate. I suggest you use a sharpie to trace the outline and bolt holes, then drill the bolt holes first. Then cut out the block plate.

Next, from the inside port on the EGR valve, there is a round port and a square port. Inside the round port is the valve needle. Drill a small hole from the inside of the round port to the outside of the valve. This will allow the EGR valve to operate when blocked off, ensuring you get no CEL codes.

Tap the hole and keep in mind whatever you drill and tap it out to you will need to have a small bolt handy to block that hole later when you pull the block plate out.

Reassemble by placing a new gasket on, then the block plate, then the EGR valve. Dont forget to reconnect your vacuum line and probably your IACV plug since it was probably in the way and you disconnected it.

The open hole allows your EGR to move up and down without creating a section on itself. And the block plate doesnt allow exhaust gasses back into your engine.
