Lukaniuk Posted March 10, 2008 Share Posted March 10, 2008 I've been having a hard time finding someone locally who could TIG weld my alum. BOV onto alum. tubing. A friend recommended just using JB Weld but I'm a little weary. Does anybody have any experience with this? Thoughts? Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted March 10, 2008 Share Posted March 10, 2008 half my car is JB wled, lol, it is good stuff Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted March 10, 2008 Share Posted March 10, 2008 I'd go to steel. Aluminum isn't worth the hassle, in my opinion. However, if you really wanna use it, just make sure you rough up the aluminum before applying the JB weld. I'm sure it will be fine. Quote Link to comment Share on other sites More sharing options...

240hoke Posted March 10, 2008 Share Posted March 10, 2008 are you guys serious! I would never use JB weld on a BOV flange. Depending on how much boost you are running and the size of the bov there can be tremendous pressure at that flange. Add to this the heat and vibration I dont think its gonna last to long. I can see your bov popping off and rolling down the interstate. Get it welded or buy a section of pipe with it already welded on from ebay or atp turbo or something.

Evan Purple240zt Posted March 10, 2008 Share Posted March 10, 2008 I had a knockoff HKS BOV with a flange JB welded on. The ONLY reason I did it is because it was temporary and now resides in the garbage can. It worked flawlessly, but bottom line is that its not a permanent acceptable solution.

johnc Posted March 10, 2008 Share Posted March 10, 2008 In a pinch at a race track I JB welded my throttle body on the intake manifold (weld was cracking). It lasted the weekend but I removed it and properly welded the part. JB Weld's max temperature is 500 degrees but that's for a one time hit. Continuous exposure to temps over 300 degrees will cause it to degrade over time. If you ever want to go back and weld the part, ALL the JB Weld needs to be removed and that includes any of the epoxy that soaked into the pores of the aluminum. I had to cut away about .083" of material on both parts to get to clean aluminum for welding. Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted March 10, 2008 Share Posted March 10, 2008 Hmm... maybe you should use some RTV black silicone instead of JB Weld based on these guys' warnings. Quote Link to comment Share on other sites More sharing options...

I have fixed all kinds of things with it and found the stuff works just like video shows. http://durafix.com/demo/256.html I have extra PM me if you want some.

dr_hunt Posted March 11, 2008 Share Posted March 11, 2008 You must be kidding me. You know when you ask for advice on using JB weld on something because it doesn't seem right, it probably isn't right. This isn't right at all, by any stretch of the imagination.

Here comes trouble Posted March 11, 2008 Share Posted March 11, 2008 I used JB Weld as a poverty repair on an aluminum L20 B cylinder head as a temporary fix where the water jackets were ate away from use of only a water coolant by the former Californian owner. The JB crap held a couple years of hard driving but exhaust found it's way into the water passage and blew the radiator apart. Put another radiator in without a radiator cap and drove it another year. The ol pickup never quit running but I left it on the eastern side of the Cascades because it lacked enough power to cross over the mountains again. Use the JB Weld only as a temporary fix or no longer than three years anyway unless you really feel lucky. It is best used in a sandwich like between the cylinder head and the block.

ShaggyZ Posted March 11, 2008 Share Posted March 11, 2008 Dude, that's cheap enough to try out... unless it somehow destroys whatever motor it may be applied to! Quote Link to comment Share on other sites More sharing options...
