JB Weld my BOV flange to pipe??

My96z said:

Can I use JB weld to attach my HKS SSQV BOV flange to my intercooler pipe? The pipe I am using is steel exhaust pipe but the flange I have on my BOV is aluminum. Will the JB Weld hold it secure?

Reason I ask is I hate to spend $42 on a little piece of steel if I can just JB weld it in there. I bought the valve used and it came with the aluminum flange.


Thanks

I ground a curve in the BOV flang from a first gen Talon. Then JB welded it to a pipe. Holds 21 PSI no problem. The stock IC on a Dodge has a substance like JB holding the end tanks on, only the Indy was welded. So I would say to try it

I've been using JB weld on various IC setups for years.

Don't use the JB Quik crap.

if the quick stuff is the sticks +1 on that, they suck..get the two tubes and mix em...it may take a bit longer, but its worth it...ive fixed pinhole weld leaks on intercoolers, and will probably use it for my talon bov flange as well.... that stuff is magic...

Thanks!!

Jb weld works fine as long as you don't bangthe thing on anything. It doesn't hold up to the quick snaps. I just woke up...having a hard time forming sentances, but I was redoing my IC setup a while back, and i had my bov flange jb welded on, and i dropped the pipe on the floor. It didn't even land on the bov, but the impact was enough to break the 'weld'.

You bought one of the most expensive blow off valves and now you don't want to fork over 40 dollars to get it put on?

Just take it to your local exhaust shop and let them weld it on for you.

Alum to steel? How are they going to do that?

Yes, I bought one of the most exspensive blow off valves USED that came WITH a aluminum flange.

jb will work just dont' smack it or pull on it at all! I will concur with what was said above I had a talon bov using egular jb and it held until I dropped it......and the weld broke=(

that 4 minute jb weld stuff sucks.

Just put on old version of the HKS on my tona...takes 5 minutes to weld it on..exhaust shop charged my friend 15 bucks to weld it on....

I tried JB welding my BOV flange to some exhaust pipe and it always blew off. I was only running 13 lbs at the time. I think it was just too hot under the hood even after sitting all night.

Mine has seen 20psi spikes.

no no what you guys need to use is that Steelie Metal expoy, it's that big chunk of grey "clay" with black "clay" on the inside that you kneed together, that's what's been holding my RFL on for years now and my RFL hangs outside my car so if it ever let go it's bye bye BOV, but I trust that Metal epoxy with my life

I tried several times, I could never get it to hold. Maybe T3 cars get a bit hotter under the hood?

I doubt it. People have repaired cracked blocks with this stuff. I fixed a crack in my head next to the oil gallery a couple of years ago, it's still there.

The key as usual is probably preparation. I sand the two parts with 150 grit, clean them down with alchohol before joining, don't touch anything with your fingers or you will contaminate the area with oil. When I apply the weld, I make a filled radius around the junction, much like you would try to do with real weld. Afterwords, I usually sand and paint the JB so you can't even see it, although my current setup I haven't bothered yet. The ratio of hardener to "steel" is important as well, perhaps your mix is off, too much one or the other. Not sure if JB has a shelf life, I go through it quite often, so it never sits around my garage for long. Dunno what else to tell you, it works for me.

Astonishing..

Why risk losing/damaging your valve over something as petty as paying someone 10.00 - $20.00 to have the flange welded on. You can pick up an alu. pipe from your exhaust shop on the cheap.

Oh, don't get me wrong, it's great stuff. But just in that one application it never worked for me. I did much as you stated, 80 grit, through cleaning and I tried to apply it in layers building it up. Sometimes it would pop before I made it around the block, other times it would last a day. Now I have a custom billet aluminum adapter welded right onto a pipe and it's been great.

Umm, they won't. You see, you can't weld aluminum to steel. Have it welded to an aluminum pipe. JB Weld is so...umm...trailer park.
