EGR Removal - 301 Turbo
« on: October 15, 2013, 07:50:15 AM »
It is my understanding to properly remove the EGR from my 1980 301 Turbo, I need the following:

1.  Block off plate with a gasket.
2.  "plug" the vacuum line.

After reading 301 articles at the 301 Garage, they talk about the feed tube? 

The feed tube will not just slip out from under the turbo, so unless you happen to have the turbo off the motor, you'll need to cut the feed tube with a cutting disc on a drill, or a short hack saw.  Leaving the feed tube in place will allow high exhaust temperatures to be directly heating your plenum, so be sure it is removed, whether you use a block off plate or a welded shut EGR valve.  Then you can remove the brass elbow from the intake manifold and match up a brass pipe plug at your local hardware store to replace it.  A brass plug is best because it won't seize up the way steel or iron will, and since it's a softer metal, it won't damage the threads in the cast iron intake manifold either.  Torque both the plug and the block off plate (with a new gasket) to 15 lb.ft.  Also remember to plug the exposed vacuum line that activated the EGR. 

Where is the feed tube located?  I thought the EGR only had a vacuum line?

Dear Joe:
Thanks for the pic.  I plug the vacuum line at the source, remove the EGR tube and "plug" the brass fitting at the manifold. 

Correct?

Wow! That thing looks worth removing.

The EGR "tube" was just as interesting to remove.  I like the stock appearance, was hoping Joe would chim in on how to proceed? 

The brass inlet can be plugged with a brass mate however, I'd like to mate to the tube as well just to keep the stock appearance. 

Thoughts or suggestions?

How about helping to keep the "stock" appearance yet eliminate the EGR?
