Working w/JB Weld

[SkiDaddy]

Last night I filled in the OEM intake manifold crossover w/JB.:cool2: It came out well but there are a few low spots I want to go back & fill in. Question is, after roughing the existing JB Weld surface w/80 grit do I clean w/Acetone? I'm concerned it might soak into the JB Weld or soften it.

Never used JB weld on an intake or anything else I always use Devcon.

Another metal epoxy.
Don't worry, you should be fine with JB.

You can clean with acetone. Won't hurt anything. JB Weld is perfectly fine for use in your motor. Most Devcon formulations and JB weld are epoxies. Lots of motor builders use it.

JB smells SOOO good

What does this mod do?
I thought the motor needed that transition port....?

Read the Duel 44 observation thread in the drive section. It made all the difference in the world for the tune ability of my motor.

Strongly recommended by a certain powerplant builder...

Use it, bruise it, acetone it. JB is more powafull than you westerners think.

i had a cast iron motor block that a rod busted through the side of it.

i got the area milled flat and used devcon to butter a peice of aluminum over the hole.


worked great for over 3 years, then i sold it.

its pretty good stuff.

It almost sounds like a corporation that some evil ruler is hiding behind from a 007 movie or something like that.

Could JB Weld be used to fill a pinhole in a B-Pipe?

 

[SkiDaddy]

You could try it. Just be sure to clean the outside thoroughly, rough up w/sandpaper, reclean, then apply. Push a ~little~ bit though to help hold it on. Be aware that if you push too much through it may break off & be pushed back into the combustion chamber by the return wave of the pipe.:bigeyes:

devcon is at mcmaster.com btw.

What's that now, like the 1757th jet ski related part that can be found at mcmaster.com?

I love it when people point that out.

 

[michael950]

If the hole in the b-pipe was not made by you, and there have been no modifications send it in for warranty.

 

[SXIPro]

Actually it is on an older ski that I am buying second hand. I doubt they would honor the warranty in that case. It's a tiny hole, so I figure JB Weld, furnace cement or high temperature duct tape and I'll be golden:Banane01:

 

[michael950]

Call first. I think it is regardless of owner. FPP has one of the best warranty on parts out there!:Banane01: :woot: :cheer: :arms:


Better to get them to fix it if possible for future reasons.
