JB weld fails below 400F.
Slightly squeeze the business end of your tube for better retention. Some muffler dope or discreetly placed tinfoil may seal things up. I have always believed that exhaust leaks are an indication of too much back pressure ![]()

Thanks. After inspecting it further the exhaust is liking around the outside. Not in the tube. Can I just tap this thing in with a hammer. I have read if it is rusted then it would be leaking through the center hole

Is the tube loose????
Run a coat hanger down thru the tube to determine if it is plugged or not. DO NOT use a drill bit. Use a small diameter wire. Try to feel for any ribbs inside of the tube. It extends (or shoul) all of the way thru the manifold and opens UNDER the manifold. Look there for leakage t oo. Note that the tube should be STAINLESS STEEL. However i i do not knowwhat Packard actually used in production. To remove tube: tap it for the appropriate size bolt and pull it out with a slide hammer. Need to do more research n this to determine if it is SS (or SHOULD BE) and whether or not it has a ribbed kind of venturi area about ceentre of the tube (it should).

I'm not sure if a pre 70'ish SBC tube will fit it or not. The SBC tube goes thru th EXHAUST manifold. A quik inspection i made of my 56 choke tube some 8 years ago made me think for some reason that an SBC tube will fit. Maybe not. Note that the tube SHOULD be SS to withstand the exh heat.

Worse case scenario is that tube is burned apart INSIDE the manifold. Which means that only the UPPER portion of tube will remove with slide hammer. In that case determine the length of tube left in the manifold and distance between bottom of tube and valley cover. MIGHT be able to drive out if there is enuf room. IIRC there is NOT enuf room to drive the entire tube out thru bottom without striking valley cover. That's why i recommend the slide hammer and pull out from above.

I looked in the SM and can not find any procedure for R&R the choke stove tube. P27 shows the intake manifold diagram and the tube but no procedureal statements about it. P27 of fuel and exh section of manuaal.

The tube is slightly loose. I can move it an 1/8 side by side.
If it breaks apart coming out can I run a rod from the top end to shove it out the bottom or is this why your saying measure it?

Log on to Ebay item number 261393105409 to get a view where you tube ends. It just goes through the "hot exhaust" portion of the intake. If you can get your finger or a small mirror under the manifold see if the end is also loose. Copper tubing might work too. If the tube is not broken than actual exhaust fumes will not be leaking. I don't know if the tube inside has holes drilled in it. I think it just sucks up heat through the choke cover. Hope this helps.
