Default Quick EGR! question

Those of you who made custom EGR block-off plates, what exactly did you use?

Sorry for the new thread, but I searched like crazy and couldn't find anything specific.

Before I cut the air fittings off the headers, I took the air tubes and cut the tubes off. I welded the holes shut and just bolted them back on. I know this doesnt help if you dont have a welder. But maybe you could run them to a shop or someone that does. It only takes a few minutes.

Are you talking about for the headers or for the intake manifold. I jb welded a cork in to the intake manifold and my buddy just drilled some holes in some scap metal and made some caps for me using the gaskets as templets.

I used a 1 3/8 freeze plug in the manifold and welding shut the tubes like whiterhino did. If ya dont have a welder just go to lowes and a small sheet of steel and cut one out that way

if you are talking about the egr hole in the intake, you can just use a rubber freeze plug. or i had an slp ls6 intake with egr, so i just used the nut that came with it and cut out a piece of sheet metal to cover the hole and screw it on...sealed it with gasket sealer too.

Sorry, forgot to tell you I have new LT's non-emissions. Isn't there another tube or tubes that goes from the stock manifolds to the manifold that need to be blocked off?

I the intake piece I found a small metal plug that was just laying in my shop welded it in. then filled the rest of the piece up with bondo up to the top, sanded it smooth/flush and painted it black then bolted it on and most people never notice it.

there are two air tubes and one egr. the egr is the one that goes to the front of the intake. all you have to do is block off that and then remove the hoses and pumps for the air and egr systems. i have non-emission LT also. it looks alot cleaner without all that crap in there

Alright, I'm going to pick up some sheet metal tomorrow and do the job in the afternoon. I can't wait to clean up the engine bay.
