Explorer egr delete?

[lagbolt]

When deleting the egr on a 1997 explorer 5.0 motor can I just cap off the port on the exhaust manifold or do I have to plug the hole in the intake manifold as well? I'm using stock explorer manifolds.

Just cap off the exhaust manifold.

From the sounds of it you have the external EGR.
For the intake you can remove the elbow (with the EGR on it) and mount the throttle body straight tot he intake. That will be a complete EGR delete, not just made non-functional.

When deleting the EGR and mounting the throttle body straight to the intake. Which gasket do I use the metal looking one that goes in between the intake and the original 90* elbow or the paper one that is in between the throttle body and the 90* elbow?

I used the paper gasket the goes with the throttle body.

OK Guys, not to hijack but I think this is relevant. What is the advantage of deleting the EGR. I have a 2000 Explorer swap I'm starting in a couple of weeks. So this is all good information.

Thanks Mark!
I deleted my EGR to get rid of the of the 90* elbow coming off of the intake to the throttle body. I was having clearance issues with my air filter tube and the hood with it running over the top of my alternator.

2000 I believe has an internal EGR. Not external like my 97.

Nope. '96 and early '97 are internal EGR.
Late '97 to '01 are external EGR.

I stand corrected. I knew it switched at some point.

So I have a new question regarding capping off the EGR on the exhaust manifold. Where I live is pretty crappy with store selection for shopping and getting parts. There for finding the right size thread to cap off the EGR port on the exhaust manifold is just not happening for me. Does anyone know the thread size so I can order one online or have any suggestions on what they have done to cap it off?

I used the tube nut from the steel hose, and the head of a carriage bolt for a plug.

Good idea garberz. How's it holding up? Any warpage in the carriage bolt head?

Last one I capped I used the line that was attached, crimped and folded it back and forth until it broke. Welded the end shut. Screwed it back on.

I don't think the EGR on the manifold is a common thread.

It's been holding up for almost two years now, I don't think it's going anywhere. The first plug I used was two pennies, that lasted just one heat cycle. The carriage bolt was the first thing I thought of after that. A correct size ball bearing would work well also.
