Back in March I got sick and tired of my noisy *** truck. So I did a lot of research on sound damping, bought a lot of products, and have gotten to work. I'd already Fat Matted the entire floor and doors, with not much improvement, so the plan was to pull the dash, get to a bare firewall, and proceed from there. Here we go.
Well, I'm balls deep in this sum*****. Its not too bad, just take it slow. There are two screws on the left and right edges of the front of the dash that face the windshield. They are a PITA to get out, no clue how I'm getting them back in. They secure part of the HVAC ducts.
Gettin' it done! Bare firewall. Starting the CLD tiles, closed cell foam, and mass loaded vinyl installation on the firewall.
So yeah, between the above photos and now, I've gone full retard on the sound proofing. While I was pulling the HVAC air intake vents at the base of the windshield, something on the turbo up pipes caught my eye. Soot. Leaking up pipes, that's probably a big noise source. One thing leads to another and I have the top of the engine dismantled replacing/upgrading/cleaning damn near every little bit. Rebuilt the turbo, installed CCV mod (routed to filter/catch tube and back to intake), EBPV delete (with new pedestal mount), New exhaust side turbo housing since crack found in old one during rebuild, new RiffRaff billet intakes, 50 cent fixes, RiffRaff FRx and HPX, new orings on everything, new up pipes, new Red Head steering box, new ps pump, Navistar water pump, new hydroboost and brake master cylinder, new rear driveshaft ujoints, etc. Like I said. Full. Retard. I'm only just now getting to the interior, but it's coming along nicely. the entire firewall has CLD tiles covering ~25% then a layer of closed cell foam (CCF) and a layer of mass loaded vinyl (MLV) then the factory CCF/MLV firewall insulator is placed over all that. All voids are stuffed with hydrophobic melamine foam. Enough talk. Pictures.
these SOBs were a PITA to remove. I think they were the originals (~225k miles)
CLD Tiles
CCF/MLV
Hydrophobic Melamine Foam
Coming together
Next up is to finish assembling the dash, install the new hydroboost and master cylinder, wrap up the cab sound proofing and then get her back on the road. Its been almost 5 months.
