Repairing cracked intake manifold

well a while back my uim got cracked on the flange at the corner bolt so i took it to get it welded. cost me 60 bucks for them to weld it. of course the retards , even though i specifically told them to, sanded down the gasket area to clean u p the weld but they didnt go and replane the whole surface. So i go to bolt up the uim and because that corner was slightly higher than the rest, the gap caused the lim to want to move up and it cracked. so now i have a hairline crack and a vacuum leak in the LIM. i dont want to waste 60 bucks getting it welded but i need to do something. i've read a little on aluminum soldering/brazing with just a low temp torch and some flux to keep from oxidizing right away and a zonc-aluminum solder. anyone know if this works or have any other ideas on what to do about this?

thanks

That sucks. I know how much trouble it is to pull the lower intake. I can't help you with the low temp torch method as I have never done it. I have heard it only really works if the part is level to the ground, otherwise the filler usually runs right off.

Yes, some of the aluminum brazing rods work, but you'll have to PULL the intake manifold, and you will need to have lots of gradual heat to get it to flow & stick.

IMHO, just get a used one.

I'll sell you a couple sticks (HTS-2000) for $5 if you really want to try.

Call Fritz, get used ones.

He's probably got so many, he's using them as coffee table bases.
