    I Have a 70 LT1 orignal moter with a orignal GM high rise...When I went to remove the heater hose nipple out of the intake I striped the threads (i knew that was gonna happen I can take care of that not a big deal...)...my problem is a small structure crack has formed on the manifold where the heater hose nipple enters the intake to about a 1/2 inch pointing towards thermosat....I was wondering if anyone know's about how to repair (alum manifolds)......If it were something else I might consider it a loss.....But I seen 70 LT1 manifolds go over 400 bucks on e-bay.....

    take it to a welder, have them grind into it a little bit to create a trench then try to match the factory look(at least contours) as best as they can.

    Sounds like a complete loss to me. I'll do you a favor and take it off your hands for $100. /forums/images/graemlins/eek.gif

    Seriously though, I had a block crack repaired about a year ago by some funky method I'd never heard of. What I gathered was that they basically used some kind of epoxy and pushed it through the crack with pressure somehow. If it works for cast iron it would surely work for an aluminum intake?

    It was at a professional engine shop up in Wisconsin that did a lot of racing and marine engines. I would think that any reputable and 'up to date' engine shop would know more about it.

    Hope that was vague enough to help... /forums/images/graemlins/1zhelp.gif
