3m Structural Adhesive is an epoxy, it's what Summit and Autoparts stores usually carry. I like it but it looks like the temp rating is 400.

3M Scotch Weld can go higher but it's usually in a double tube that takes a gun. And there's a lot of different part numbers.

JB is rated to 500. I use a ton of JB.

Where exactly is the crack,David?

Wait, is this one of those CV or Mercury Cougar 4.6 intake manifolds from the mid to late 90's? There was a large lawsuit which covered certain years which was then opened up again to cover later models to 97 if I recall.

If that's it, go to the junkyard and grab one of the replacements that Ford installed as a result of the class action suit. You'll know as it will have the Ford part numbers, not Dorman (skip those). That replacement will have a aluminum cross over at the thermostat housing as well. You'll recognize it that way.

Too late to get a replacement as a result of the class action. I did the replacement after messing with the glue because nothing worked. The job is not bad at all.

Replace the rubber hose in the galley below the intake when you get there.

I'd v-grind it just a little with a dremel and JB Weld it.
As long as it's not right beside the exhaust manifold, it should hold fine.

I JB'd a pin hole in the radiator on the racecar and it's still there after 5 years (and still not leaking).
