If I plug off the EGR vacuum line, do I still need to block off the EGR exhaust gas tube?

 

What are you trying to accomplish? Did you get headers without an EGR connection? Just trying to clean up the engine bay? Assuming there is some sort of performance gain?

 

If you have a faulty EGR, it will still leak after you plug the vacuum line. To totally do away with the EGR, you can jusy pull the EGR off the manifold and make a gasket to block off the top port. I used 3 layers of Dr Pepper cans and it works great.

After that, you can plug up the line at the headers and take out the tube that goes into the manifold. You dont need to plug that hole, as long as you plugged up the EGR well.

 

I'm sorry, I am done with my header install, and am still confused on what to do with my EGR. I was told by one person If my EGR works fine, I would just need to plug off the vaccum feed. I was wondering if there would be anything else to do.

 

Plugging intake hole mandatory and will let you avoid vacuum leak. If you leave EGR solenoid vac line unplugged/opened EGR membrane will never open, so it's somehow fine. But EGR will give you trouble code anyway (I am not sure on '94), since signal to open EGR will not result in voltage change from MAP. Cleaner way - remove all EGR stuff, there is a lot of info on this board on it...

 

You still haven't answered the question... WHY are you deleting it? What you are trying to accomplish will dictate what you need to do.

 

I am getting rid of it because I didn't know whether or not I could keep it after my non-emission header install. If I can just leave it all there without a problem (after the exhaust tube has been disconnected) it would be nice. Does that help....or do you need any further information?

Ok, so you can plug up the EGR valve by removing it (1/2 open box wrench) and cutting out a gasket of some kind to plug up the holes.

Once you get the EGR valve plugged, then you can leave the vacuum line on it because even if it opens then the exhaust gas will be blocked by the plate.

Then if you have Off road headers (no EGR fittings) then you can remove the EGR exhaust gas feed pipe. You dont need to block off this hole because it just goes straight to the EGR valve through the intake (doesnt go into the plenum).

Hope this helps.
