EGR blockoff plate

Anyone know where I could get the EGR blockoff plate for the EGR port on an LS6 intake with the EGR provision? All I can find are the plates that block off the EGR port on the headers. Thanks.

You aren't looking for a block-off plate, you want a freeze plug. I think it's 1 3/8". (don't quote me on that, it's been awhile) Should be able to find one at a local auto parts store.

I checked, I'm almost positive it's a 1 3/8" plug.

In that thread they say to use a 35 mm freeze plug. Which one should I use, a 1 3/8" or a 35mm?

I used the 35mm. The other may work I just have not tried that size personally. The connection can just be taped up. Mine is just tucked back out of the way.

1 3/8" fits great, just did it to mine. I also taped the connection up and let it hang. I'll tuck it out of the way one of these days. Just expand the freeze plug using a vice and a wrench until if fits real snug, then tighten her down the rest of the way. Otherwise, it'll want to spin on you.
