Ford 390 Intake
So this guy is selling this intake manifold for really cheap, but it appears to have a crack around one of the bolt holes. I was wondering if this is an expensive fix or if I should not even bother buying it.

Aluminum?
It could be TIG welded.

Re: Ford 390 Intake
Yes, it's aluminum. I don't know how to TIG weld so would it be expensive to take it to a welder and have him do it?

Re: Ford 390 Intake
Stock cast iron 2 barrel intakes are plentiful, so probably not worth the expense.
If it is something special, repair may be worthwhile.
Oops, didn't see the previous post. My point is moot.

Re: Ford 390 Intake
Problem is that it appears to have affected 2 sealing surfaces. It will have to be welded and then machined...
I would guess that it is going to cost more than it is worth unless this is some sort of rare original intake.
Who dropped it?

Re: Ford 390 Intake
If it is otherwise a good intake you could possibly get it TIG welded. Does the crack only affect the rocker cover gasket surface? If so I don't see why you couldn't file a V shaped groove into the crack and have it welded. Then carefully file the gasket surface flat. If it is cheap enough it might be worth it.
One thing that could give you trouble is if the welder gets it too hot It could potentially cause warpage, so I would think keeping the intake cool during the process would be important. One could stitch weld it together slowly and keep a wet towel on it between, although I have never welded a cast aluminum intake so this is merely speculation on my part.
