JB Wield

[AnthonyX99]

Hey guys been awhile since I posted here. The back of the engine, the studs pretty much snapped and I can't tap it because there's no space at all I need a m7 stud and thats not going to work. Now for my question if I applied Jb wield to the engine and stuck the spacer on it along with the new steel pipe I'll be using I'll be using it on the pipe as well, Will JB wield be able o take the vibrations and not crack or just fail all together?

From experience fix it right. For every 1 success Ive heard Ive seen 6 failures in trying to repair something with JB weld. It has its purpose but not in a fix for a part you depend on. Thats my take.

I forgot to add the engine will be sitting on two steel plates side by side set vertical so it wont be floating.

i doubt it would work. and for the amount of effort you're going to put into something that will probably end in failure, i'd take the engine to a machine shop and have them get the snapped studs out for you.

then, i would figure out why they snapped in the first place, and fix that (without JB welding anything.)

JB Weld isn't nearly as strong as cast aluminum (see attached typical properties of AL vs JB Weld). However, might work in some applications as a filler in a confined space, but not with heavy or repeated loading; i.e., vibration. In any case, I agree with removing broken stud(s) and replacing.

JB weld is crap, the only thing I ever had success with while using JB weld was welding a friends locker shut back in high school.....


I just removed a snapped off stud from my motor today by using a rotary tool with a cutting wheel and cutting a little slot into the stud. Then it came out with a screwdriver quite easily.

Boy oh boy, Anthony. In case you didn't notice, JB mentioned around here is like calling someone's mom a colorful term! With that out of the way, I've had a lot of success with JB STIK and similar products. NOT THE 2 LIQUID TUBES. I've had success with the liquid, when used for it's purpose, but the stick putty type work great, again, for their purpose. I will have to agree that JB, in most cases, should not be used for a permanent repair in this type of application. You are asking for failure and wasted time. I will use it in a split second to do a quick fix for something temporary or some not so important fabbing, like rear view mirror mounts or something. Just my $.02. Best of luck getting it repaired.

JB weld is not good for extension stresses. Get it meaured, weld and re drill.
