The insulating panel above the engine in my H36 has come unstuck and keeps falling on top of the engine,

This is a foam panel with foil on the side facing the engine.

Other than duct tape - do you guys have any suggestions as to how to properly glue this soundproofing panel back in place ?

this method is great providing you have a plywood core to screw into...

in the past I have used #6 or 8 screws long enough to reach thru the soundproofing material without crushing it, with large flange fender washer on the screws to attach it to the walls and top of the compartment.... the screws should be placed every 10-12 inches to keep the insulation secure.
this is a permanent, yet removable install that wont ever come loose on its own...

Same thing

I had the same thing happen on my 2007 H-36 and I think I may have used a staple gun with long reaching staples and pretty sure that's what I did and will look for sure

you can also use ss roofing ring nails with the plastic washers

I've always been skeptical of engine-room insulation that is meant to be attached solely on the basis of mastic. In the south, engine rooms get pretty hot, causing the mastic to release.

Auto Zone carries Heads Up/Quick Fix headliner high heat spray adhesive. The underside of the roof of a car can get up to near 200F. I've used it to glue headliners in and so far they haven't fallen back in my face while driving.
