I need to epoxy a piece or two in my al intake. Are the more expensive epoxies like Moroso better than something like JB Weld? I don't need a lot of strength, I think the most important thing would be adhesion to two pieces of al.
What epoxy would you recommend? Thanks!

MarineTex gray or A-788 Splashzone for gas engines.
Belzona 1111 for alcohol engines.
Getting a good mechanical bond is very important.
So, make sure you prepare the surface so there's plenty of mechanical "grip", degrease with acetone, and it'll never come out.

Gas engine, so what's the source for the MarineTex or SplashZone? I have never heard of either.

May sound crazy, but I just patch coated some rivets on my aluminum fishing boat with some epoxy I purchased from "Fasco" out of Hileah, FL. Think the website was fasco.com, but search on "Fasco, Hileah, FL" and it should come up (or "aluminum boat patch epoxy). I love the stuff. It worked great and I talked to them on the phone. They were helpful. You could ask if they have some that will not deteriorate with alcohol. They have many, many kinds. On the boat I used "Flex Steel", which has teflon in it for coating the bottom of boats, but again, they make all kinds. Just a thought.

And even the 10% blend is enough to cause Moroso's epoxy to "unglue" from the intake, as I can confirm first hand. 
If there's alcohol in your fuel, find that Belzona stuff someone mentioned above. But don't expect it to be cheap!

Wow! More choices than I thought there would be. And a little more complexity. Thanks for the help, guys.
