Intake Minifold Heat shield
 

Hello you all,
i need a little bit help. My 3,5l H3 is sucking air somewhere under the "heat-shield" of the intake manifold. I think it's at the connection to the pvc-hose of the crankcase ventilation. Can somebody tell me, how to remove the "Heat-shield"? I looked for clips or something like that, but was not able to find something.

Greets,

Jens

Identical question, different forum, identical answer? ;)

Are you talking about the PVC hose under the throttel body resonator box?? #6 below?

If so, the rubber hose connects at the bottom rear of the black plastic box to the valve cover. Loosen the hose clamps connecting the rubber intake hoses to the plastic box, there are two 10MM bolts on the left side holding the box in place. Take out the bolts and lift.
