I have one smog system that is non functional. I took out the inserts and put in a button head socket cap screw. One similar to this, but without markings on the head. Smog pipes seal nicely against these.

Roofing nails work great

I used steel rod and welded a lip on it like the tubes had. Just slips in the hole where the tube was and the upper tube clamps it in place.
|
1/4" clevis pins fit perfectly in the tubes & it has a flange that will seat against the manifold. Pull those long tubes out of the manifold or the nut on the tube won't look correct. No welding is needed. I did this on my big block car at 83k. At 157k they looked just fine. Use a BB in the vacuum hose from the carb. to the deverter valve. I just mentioned all to Larry Christenson & that's what he said he would be doing. Really easy....Joe

What is the reason you want to take the tubes out ?

I tend to remove the stainless injection tube, put them in a bag saved for future use as needed, & install a suitable mechanical "plug" (i.e. Nail, Screw, Clevis, Machined plug) UNDER the Nut of the Smog distribution Pipe manifold or "Tree". I see no reason to leave the injection tube flapping in the breeze of the exhaust gases path.
I do not like the PaceCar jeff method since it potentially damages the manifolds (Tube) female tapered seat. Good topic with Lots of great ideas and a variety of methods. |
