Hello everyone,
I need a little help. I tried to block off my xover tube today, but I could not figure out how to make the 1-1/8 freeze plugs work. I included some pictures of the unplugged egr and of the xover tube removed. Maybe someone can tell where I went wrong. I not sure if you're just hammer the plug in to the right side of the tube or what. Also the left side of the engine the tube opening is 1-1/4 inches, different than the right side.

Thanks

First off, that plug is not the one you unplug. Many guys had problems after unplugging that one. You only unplug the one on the other side of the engine.
I'm interested to hear on the freezeplug thing too because I am planning on picking one up today and installing it myself. I would think that whichever way it fit easiest, either in the tube with the cup in or in the EGR housing with the cup in, would be OK as long as you can get it back together with the clamp. If you have to just lightly tap it in then I don't think that would hurt anything. If you really have to hit it hard then I think that may be a problem.....

 

Thanks Dodgezilla for the info. The 1-1/8 plug fits the right side of the tube but you can not get the tube back together with it in. At least that was my problem.

 

Alright, my NAPA had the 1 1/8" freezeplug in stock. I pulled the X-over tube off and installed the plug in the tube on the left side as you look at it. I put the dish in first and tapped it in with a hammer. Had there not been so much soot in the tube it may have just slid in.

Easy Breezy.....

 

OK, I'll give it another shot, there was a lot of soot in the tube.

 

It will work. It was a bit tight but it went in further and further each time I tapped on it. I went until it was flush. I just hope I never have to get it out.....

 

Ok so i un plugged the egr and my truck still runs lol. So now what? Take the cross over tube and just plug it? Is that all that i need to do? What else should b done? Thanks

 

If your mileage goes up and the truck continues to run fine then you can just leave it alone. Testing has shown that just doing this does still allow some soot to get past the EGR butterfly and get into the intake. For that reason many of us have put block off plates between the EGR housing and the manifold where they connect.
The reason we are installing the freeze plug in the tube is because soot is still building up in there even though we have blocked it off. The hot EGR gasses combined with the cooler intake manifold temps are causing moisture to build up in the EGR housing if that tube is not blocked. Now, if you never intend to use your EGR again then who cares?!?! BUT, if you may ever have to succomb to an emissions test then you will want you EGR to work and keeping this crud out is the way to make that happen...
Now, if your truck seems to lose power or does not gain any mileage then the butterfly valve in the intake manifold may be partially closing while driving in which case it would need to be removed...
Your truck should only regen about half as much now too....

Many thanks to Polaraco for being the one to come up with these test results. He is the EGR master and I am merely known as Grasshopper.....

 

Ok, so i will have to wait and see about the fuel mileage. But the power seems fine. So what is this about putting the freeze plug in the cross over? Would that help anything?

 

Read my last post again...

 

Gotcha lol! So to completely block off the egr and everything I need to get plates and then install the freeze plug. Where is the best place to get plates? Or r the easily made? Then if i do the plates and freeze plug I should remove the butterfly valve? Where exactly is that and whats the best way to disable it? Sorry to ask so many questions but as u know there is like thousands of posts on this lol. Thank you for your help!
