What is your craziest successful JB Weld truck repair (or other)??

[prostreetC-10]

JB Weld has a different produce out that I haven't seen before. It might have been out for awhile but I only knew of the 2 part tube. It's call JB Weld "Steelstik". I have read some pretty crazy things have guys have successfully repair with this and the original stuff including cracked engines (water jacket stuff).

What is the best repair you have ever done with JB Weld that is still holding up today??

I guess I should add my own story. Ran over a huge rock in my old Mercedes. It went down the bottom and punched a hole in my trans. I was too broke at the time so I used the old JB Weld to fix the hole. Always exposed to hot trans fluid and never leaked.

I've been using JB Weld from the time it came out in the 60's. Poor country folk make do with cheapest easiest repairs. I always keep some in my tool box.

The best uses were to repair a cracked AFB Carter carb mounting base for my 56 Chevy back in the 60's, done some minor body work, fixed a crack in an exhaust manifold and recently used it on my tractor. In between I have used it for lots of other minor repairs but too many to mention and some can't remember.

When I was a kid I couldn't get the tire bead off the steel rim of my go-cart so I cut it with a grinder but I ended up grinding through the rim. So I patched the rim I never lost air with the new tire. It held up long as I owned it.

This spring there was a hole on the bottom edge of my service tank. Mixed up some JB weld screwed a screw into the rust hole and it leaks no more.

power steering pulley rubbed a hole in lower radiator hose on my mustang so I jb'd it so I could go chase tail in town, held up so well sold the car that way.

The throttle linkage support on my 70 had a groove carved into it from the carter pin making it stick. JB welded the thing and it is still holding up!

Back in the early 90's my friend gave me his '71 GMC 3/4 ton because he needed it out of his driveway. All I needed to get it running was a battery and replace the ramhorn on the passenger side. I grabbed a battery and got it started, but at the time I couldn't afford much, my son was pretty young and I had to make it work. The hole was about the size of a nickel and right in the middle of the manifold, right where the tubes meet (typical). So being broke I used a big wad of JBWeld and it sealed for a while. I wound up getting some header wrap also and plugging the hole, and wrapping the manifold to keep it in place. That stayed until I sold the truck a couple years later.

I know a guy who fixed a head on a pulling tractor with jb weld. In competition on a friday night they burnt out the head from the chamber past the fire ring and all the way to the outside. After removal they did not have a welder to fix it and needed to run sat night. They got jb weld and formed it into the burnt area and layed the fire ring back in to make the groove. Let it set overnight and it made a pass. It will stand 1250 degrees and 100 lb boost.

fixed the crack in my 07 600 katana's crank case cover. not as crazy as some of these but i was proud of myself since it was the first time i have ever used it

I have fixed a cracked alum. carb spacer or two and once even a cracked holly fuel bowl. On my 72 Bug the carb has a dime size factory plug that is known to fall off. Once driving it shot off so I did the V.W. roadside repair. I took a dime ground down the edges and placed it in its place with some J B Weld. It's still there. But...my most recent was my Black and Decker weed trimmer. The plastic guard had broken off of the base and cracked in half. I used J B Weld to piece it back together but it would still spin on the base. So I used it to "weld" it to the base. Problem solved.

in the early days of our racing and before dry sump systems, we ran big oil pans when the car came off the track it would scrape the bottom till it got ahole in it ,just mixed up some jb and coated the bottom , no leak

Flared and joined an aluminum fitting to a copper pipe on an AC condenser.

Really didn't expect it to work. After it setup for two days, I intentionally tried to break it and couldn't. Bent the copper tubing, but the joint would not budge.

Very impressed with JB Weld.

Fixed a hole in a refrigerator evaporater coil. It held up under constant pressure for several years.

Oil pan on an s10 blazer after wheeling and poking a hole in it. It lasted untill a friend of mine had bought it 7 years later and after many nights of mud bogging it scrapped it cause a brake caliper was seized... also a guy getting his series 60 detroit overhauled on a low budget did not have the money to fix the damaged fire deck correctly. So to get him down the road we cleaned it real good, applied it like body filler over the bad spots. Then filed to perfection. That was 3 years ago, and the guy is still makin money with it

Best fix was on a farmall H. All the radiator brackets came loose so I glued them back together with jb weld. Also used it to fix a bad fitting in that tractors hydraulic system.

I repaired the crankcase/chain cover mating surface on my Quad 15 years ago. I needed to file it perfectly so there were no leaks at the gasket. I was amazed that the stuff held up at all.
Now I am trying to get rid of the quad...

Recently I made a new lug on an old Briggs and Stratton motor to mount the fan cover. The lug where the cover bolts down had broken, and its cast iron, so welding isn't a good option. I made a little cardboard form and packed it with JB to make the new lug, then drilled and tapped.

On my truck I rebuilt my heater controls where the original rivets had broken. The whole back of the panel is JB Weld.

Last week I broke off a tap chasing holes in the block of my 327 I'm building. 1/4" tap snapped right off in an oil pan bolt hole. after multiple attempts i got a special carbide bit and drilled it out, but the hole was out of round and bigger than the size for a 1/4" helicoil. So I filled it with JB weld, then drilled/tapped/helicoiled. Should be a good permanent fix.


In industry there is a similar product called Belzona. I've rebuilt boiler pump casings and shafts with it and had them last for years. Its basically heavy duty JB Weld.

Fixed the keyway on a crankshaft snout. Worked great.

[hounddogs!]

Not proud of this, but I've repaired gas tank leaks on three different cars with it. '87 Accord, punctured on a RR crossing; '87 GN, corrosion above the hanger straps; '95 Corolla, crimp joint that failed.

prostreetC10, cool thread... you may be able to sell these (stories) ideas to JB weld in the end :-). What great stuff!

This older woman I do work for on her farm has a pond with teak lawn furniture that got moss and lichen all over it. I pressure washed it and was going to put preservative on,which I did later. But first,I noticed all the legs had hollowed out cups in them from sitting on the ground. I started off with JB-Weld but realized that was too slow and costly. Lowes has some sort of epoxy like JB in small cans. I masked the legs up about 1 1/2" and filled the hollowed out legs and coated the 1 1/2". The epoxy sealed the rot,won't absorb ground moisture and is sealing that 1 1/2" so leaving in the grass is no longer an issue. It looks really nice on there,like it was made that way. The furniture looks like new and will stay that way and it was real simple to do.

I recently repaired a hose fitting on the top of my charcoal canister with JB Weld and a ball point pen refill.
