Intake port not plugged?

[cdvcj8]

My son asked why the Jeep was suddenly making so much noise. Upon investigation the exhaust pipe had split at the flange for the exhaust manifold. I got a replacement pipe and am going to hack it in temporarily (considering an engine swap, but that's another story). When I got some light on it I see that what looks like a port on the bottom of the intake manifold is not blocked. I'm assuming it should be??? If so, would this part work:

EDIT: After research these look like they are for the exhaust manifold

Thanks,
Chris V.

It's for the end of the pipe (egr tube) that comes from the intake manifold. I think your best option is to hope it's still threaded and find a plug that will fit. I'm not sure on the size though.

If you wind up needing a new intake/exhaust/egr tube, let me know, I'll be pulling mine in a couple of weeks!

What he said

Collins Brothers sells replacement tubes, made out of stainless, or they did a few years ago.

I have a tap to re-thread the holes, and I bought some plugs from somewhere, too. I can post up the tap size and info if you want, I have had to repair a few of these before, replace the tube, or simply plug up the holes. To install the tube, I have found the easiest way is to have the exhaust manifold bolted to head, tube started in exhaust manifold, then lower intake on to tube, start the threads in the intake, then tighten intake to head, then snug up the tube on each end.

Thanks that pointed me in the right direction. Mine has a thread already and I found another discussion that said an oil drain plug of size M22-1.50, HEAD SIZE 19MM from a Dodge truck would work. I'm going to try this:

That might be the plug I used, in conjunction with a steel washer, IIRC
