This is a no fluff step by step video showing you exactly how a professional fabrication and welding shop repairs someone's mistake.
In this case, I tried to MIG weld a stainless EGT bung into a cast manifold using an old Harbor Freight flux core welder. It went 50 miles before cracking off. My Turbo Diesel Mercedes was down for the count after this until the guys at Fluid MotorUnion saved the day.
Huge thanks to Fluid MotorUnion in Naperville Illinois. If you need anything done to your car just give them a call at 630-305-3054 and mention LegitStreetCars.

Good job on the pulse setting.
Maybe the Welder use the silicone bronze filler rod, not normal stainless steel rod, maybe 309lsi filler is good for cast iron, but the gray cast iron will cracking of, So a stick with a high nickel content should be used
So if you were going to weld a cast steel turbo manifold with a stainless steel pipe.. so cast steel to stainless…would you use a higher nickel filler?
silica bronze would be easier.
Should probably be titled “ welding new bung on my manifold”
what did he charge you for that job?
I need teepee for my…
Welding cast iron is tricky. Without access to a TIG welder ( And the necessary skill to operate it. ) you have to preheat the iron before attempting to weld it. MIG won't penetrate enough. Use a stick welder.
What was the weldingmaterial used to weld this stainless steel onto that castiron manifold? Was it 309?
I live near Naperville Illinois, i just bought a pretty nice e320 Mercedes for $1200 in Addison Illinois
@legitstreetcars What modifications do you recommend for reliability on the om648? Egr removal? Swirl Flap delete? I have to build a custom intake for my om648 to fit it in my Volvo C304 and I figured along with that I will delete the egr and swirl flaps. What are your thoughts? and how would I go about deleting them?
Ok I'll do it… points at Alex and goes ha ha!
You should have stuck your camera inside a welding mask to film the weld part.
I’ve welded my fair shake of cast manifolds even have a video of it on my channel, from I always pre heat the cast and what I’m welding to it also slow cool it after welding for a crack free weld. Since cast and stainless have different heating and cooling properties if this isint done it will usually result in a crack at the toe of the weld after a some heat cycles. I’ve seen it good without a pre and post heat but why chance it and it will last a lifetime if done correctly. Great content nonetheless
That beard is fucking sinful.
For something that needs to be dependable you either need to be a decent welder or at least use a decent welder like an Everlast or something and not a harbor freight welder.
