The 2.5" exhaust manifold on the drivers side of my 64, has a choke tube through it that is not being used. However it seems to have sunken or receded a little, and this has left a small gap, and therefore a tiny leak too, although undetectable.

Anyone have any ideas on how to plug it up, ( I am not a welder) so just looking for an easy fix for a temporary solution. Or do I need to just get a new manifold?

Driver's side?

Yes, Drivers side

Yes, give me your phone number and I'll contact you and I can arrange for you to have one with no hole.

If the left manifold has a choke heat tube it is a fuelie manifold . If it is in good shape you could sell it and use the money to buy a new set .

Yes my car was originally a fuelie....(long gone before I got it) I have both sides. have been doing an overhaul on the engine, and broke an ear off trying to get the studs out on the passenger side, and had to get a replacement, and was hoping to be able to make the drivers side work, but they might both be up for sale if I cant get this repaired easily. Unfortunately I didn't notice the problem with it until the last minute after I had cleaned it all up and cast blasted it.

I didn't no they made a High temp JB Weld, will have to look into that.

Thanks

JB weld will last all of 28 seconds. This is an easy fix. Remove the existing tube completely and just replace it. The choke tube can be purchased from most any parts house.

Removing the existing tube may involve drilling the ends out. Take your time and use a drill bit that is smaller than the manifold hole.

That's what I would do; you'll still have the hole visible but the new tube should solve the problem...

Mr D.

I agree with TC the correct and easy fix is to replace the heat tube. Pull the manifold and get it on your workbench and the job will go much smoother.

Thanks guy's, I never would have thought that the tube alone is replaceable.....That's the route I'm going to try and tackle.

It seems to me it's gonna be easier to get it out than to get the new one in. How exactly is it installed, does it need to be pressed in somehow?

It comes out from the bottom end, where it's staked in place; the replacement installs from the bottom up. Paragon has them.

HA HA!! Thanks Mike, that's an easy way out I suppose.

I think though, since John Z. has pointed out the way to install the tube properly I'm gonna' give it a try...

Thanks for the advice and help from all, When all the parts come, I will report back the results when I'm done.

Oaker57

Ok, I'm sure you guys are sitting on the edge of your seats waiting to hear how I made out with the choke tube dilemma......

Well its all fixed!! After contemplating all the advice laid out here, I thought if the new tubes are driven in from the bottom up, and mine was sinking from the top down, and had only moved an 1/8" in 50 years, why not just try to drive it back up into place. So using the proper sized punch, I was able to carefully set it back into place with some diligent but firm raps with a brass hammer, while my buddy held a small phillips screwdriver in the top of it to guide it into place until it seated into the hole. So I lucked out on this one.

Thanks again to all that replied.

Slick fix! Sure beats R&R exhaust manifold. No telling what else you would have figured to do with that manifold off
