Check out this website:'s plastic

and this website on a recall: yes, it says Crown Vic but covers others with the 4.6 and the plastic intake manifold

It's a common failure for Ford 4.6L intake manifolds. Replace the manifold (I know it's not cheap) but that's the only fix I know of. JB Weld should work for a while but usually, it isn't a forever fix. It isn't a difficult part to change and the gaskets are re-usable if they aren't damaged. Be sure to soak the EGR tube with WD40 or other penetrating oil.

DavidH25 your handle on these resources never cease to amaze~ GURU number ONE for a reason~

How could a mechanic NOT overtorque this creation? The design is laden with flaws....a world of better ideas comin' from FORD!

Tracy Hooks

A Technician wouldn't over-torque them because he's read the specs and sequence first. Besides, it's pretty hard to screw up with the steel inserts the bolts go through.
