79 4-2-1 exhaust egr plug

[garion]

Hi guys.. As I prepare to swap my 1800 head to my 2L, I hvae the 79 4-2-1 exhaust, with that extra pipe for the EGR.. Since I'm not going to have the extra port to hook it to anymore with the 1800 head, I'd like to remove that pipe.

What size plug do I need? I *think* I've read that its the same as the oil plug, is that true?

Fixing to do the exact same thing on my '79 Automatic. Hope someone responds. I do know that some guys have cut a solid "gasket" from copper and just plugged up the hole that way. Apparently on the intake side it is just a hole thru the block with no connections to anything.

FYI- I didn't end up removing it.. I covered it with aluminum..

On the exhaust manifold, I placed the exhaust gasket (for an 1800, so it doesn't have the extra bit for the EGR) on loosely with a could bolts.. This showed me the area I needed to cover.. I took some flat aluminum, and cut it to the same.. I then drilled a single hole where the one bolt goes through...

I then filled the hole with some muffler putty stuff (letting it dry for several days).. Then when mounting it to the car, I put alum on, bolted it place, and added the gasket.. If you do it right, there's some space where the gasket doesnt cover, but is clamped between the head and manifold.. I'll try to take a pic if you're interested..

I usually cut the pipe and crimp it shut/bend it back with wise grips.

I'd love to get the thing off, and just plug it... But I couldn't get it to turn, its so rusted on there.. I also didn't remove the manifold from the car, so soaking in PB blaster wasn't really an option...
