Epic Fail

I installed the fuel rail and  hooked up the wiring to the injectors and was bolting on the upper intake manifold when disaster struck. The book calls for 34 Nm torque on the intake bolts and my 3/8" clicker torque wrench has the gradients etched into the shaft (10,20,30, etc) and smaller gradients (1,2,3 etc) in the part that twists around. The top gradient in the shaft is 29 Nm so I turned the handle up to that, then added 5 more to get 34 Nm, the recommended torque. The wrench definitely clicked but then I felt a pop, the pictures explain the rest.
So, the intake is junk and it's cast aluminum that is difficult to weld.
