Hot Rods HAMB friendly Quadrajet repair...

At the Relix Riot this weekend, the Quadrajet on the 472 Caddy in my '36 decided it had had enough of the threads in the inlet, and began leaking. Back in the day, when every other car on the road had a Quadrajet, all part stores had repair kits for over-tightened inlet fittings, but this is 2011, it was Saturday evening, and I wanted to cruise around the grounds in the roadster.

I posed the question to several of my buds from the "Relix" car club who wre there when the calamity occured, should I try wrapping the threads with plumbers teflon, tin-foil, or use JB Weld?

One of 'em responded, "Post it on the HAMB", so after the fact, that's what I'm doing.

So, given the same situation, which "repair" would YOU do? I won't say which one I used, but I will say it's still leak free today, and I drove the car about a hundred miles since I "fixed" the carb. It seems to be permanant at this point, so I'm not inclined to fix it any further!

JB weld if you let it dry. But a helicoil is the way to go.

 

second the jb weld. You can even tap it when its cured.

 

cliffs quadrajet has a fix for this. I have not used it but it can be seen on the web site.

 

So far, it's JB Weld two, really fixing it one. Wonder which route I chose?

I'll vote for tin foil.

 

I know what ya did, but I won't tell on ya...

 

I vote for bubble gum and duct tape!

 

I'll second that. Cliff Ruggles is "the man" when it comes to overhauling a QuadraJet!

 

lol, i REALLY thought the tin foil was gonna work, too!

 

I used to use a Tomco repair kit that works kinda like a rubber o-ring expansion plug. But if you can't find one of them, then glue the stripped fitting in (JB Weld), let it set up and pray it doesn't leak.

JB weld is the only one of the three that's permanent

 

I have sent him a note a couple times about rebuilding mine and both times he has been too busy to do mine????

 

what housing do you have ? I have lots of Q jets setting around

 

I used JB weld on my '68 Rivi. I sold the car but I know it is still in there several thousand miles later. Cleaned the inlet with lacquer thinner while on the car. Spread the JB weld on the inlet fitting, tightened everything good and drove to work the next morning.
Got great mileage too - on the freeway

 

JB Quick. Be back on the road in 15 minutes.

 

In the situation you were in I'd guess teflon tape for a temporary fix. That stuff can work wonders in a pinch.

 

JB-weld (and a fire estinguisher) to get it home (or better yet, a trailer).

Once home you have a number of options:

(A) Tap the threads deeper and use a fitting with more threads
(B) Tap the opening for an oversize thread, and install an oversize fitting
(C) Heli-coil the opening and use the standard fitting

JB-Weld WILL soften over time in the presence of gasoline. It took about 3 months in the test we did.

The HAMB friendly repair would be to put 2 97's on one of those ugly ***ed adptors and use the red translucent fuel line.

 

If this is the big OD fuel nut fitting, there is really no traditional re-threading option for it since the thread is so large and fine in pitch. I've used gas seal tape for it (made for natural gas & propane), good in a pinch. The best option is either a new body or one of the fix kits, which I still see around at older real auto parts stores.
