Quieting the Engine
While I'm on the topic of that center seat support: Last fall I noticed that most of the engine noise in the passenger compartment was coming from that center seat support. It turns out that there is a open gap on either side that conducts noise straight from the engine compartment into the passenger area. In addition, the front of that center section is a single layer of fiberglass - not very acoustically isolating.
The front of the section was deadened by the addition of a layer of engine-compartment-rated acoustic insulation ("Dynamat" is a popular brand, though this is a different product):
The gap was handled by installing a strip of closed-cell adhesive backed gasketing material to both sides of the section...
...that compresses when the center section is installed:
Next up: Intake pump installation. Thanks!
