Rear Engine Intake Manifold

[Pat Schmitz]

what's most interesting, is the apparently (cheaper) thinner-walled aluminum tubing going to the intercooler did not wear through, but the much thicker (more expensive) manifold wore through!!?? Apparently the metal composition on the manifold must be softer...

Has anyone had any weld repairs done? If so, where do you suggest? It will probably be more work to remove it than it will to weld it back up...
