JB Weld to fix crack in aluminum intake
Bought a 390 with an Edelbrock Performer 390 intake manifold and I noticed that the manifold had a pretty long crack around one of the bolts that hold it on. I pointed it out to the seller and asked him how the truck ran and he insisted that it ran great. Can I fix this crack without having it welded or should I even worry about it? Thanks all.

JB Weld will work well on aluminum. Repaired a few motorcycle engine side covers with it. As long as it's not leaking, fluids, vacuum, my only concern would be the crack getting worse. Just don't try tightening it anymore if leaking. Aluminum manifolds require lower torque specs than cast which probably overtightening caused this to start with.
