How to soundproof?

[Homer T. Coyote]

I am going to try to find a TDI engine cover as it is supposed to absorb some of the noise.

I put a towel at the bottom of my glove box. It's incredible how much noise those little boxes of fuses made, bouncing around like they were.

The G60 valve cover is a bit heavier and uses a better gasket that NEVER leaks.

I somehow got ahold of a G-60 valve cover, was thinking of putting it on my diesel Caddy

just use the factory gaskets?

It's kind of a cool looking cover, worth anything?

This is the G60 cover I put on my 81 Caddy 1.6TD. I also used the baffle and gasket/stud conversion/upgrade kits available off eBay. No leaks at all.

That is one sharp Caddy. I didn't think out the valve cover but if its cast aluminum I guess it would help too. I was actually speaking of the large plastic (I guess) engine cover that covers the entire engine. I don't recall where but I read that it was there for noise control.

Vanagon Mark...

The G60 valve covers use a one-piece
rubber gasket that seals better.

The valve covers are quite sought-after
and usually sell for around $60 to $100
depending on the condition.

That valve cover works great with the turbo or A2 intakes but the A1 intake interfers with it.

VanagonMark...

One thing I forgot to add, the G60 Valve cover/rubber gasket
set up requires the use of shoulderless valve cover studs.

I uhhh errr... have too many cars to list... well that's not true
OK, good point.
I'll count my cars and list them.
Does the Blue bunny count?... now that the rear end has broken lose?
Projects or just running projects?
Decisions, decisions.

I had something written but hadn't checked yes in the space that makes it visible.
It still doesn't show so I'll have to work on it.
Oh, look there it is, I just needed to make a new post.
Ya happy?
Like Hagar and Bunny Bondo?
I hope so.

I have drastically reduced interior sounds and I dont even have carpet or a headliner yet.
First I replaced the roof sound deadening with a layer of thin foam/foil stickybacked insulation from home depot, then glued new foil backed jute padding to that. That cut down a lot of sound
Then I covered the underside of the hood with the double foil backed jute, and the firewall. That helped some.
Another effective noise killer was adding a layer of sticky backed asphalt roofing to the inside of the doors to cut resonance. I replaced the door plastic seal with hardwood floor foam underlay/water barrior stuff. I used home acrylic dap caulking to stick it to the door and applied a lot of it because the rubber also dampens vibrations.
The real sound killer was what I did today. I picked up the under carpet deadener which is a dense jute with a thick rubber mat attached to it, from a 99 oldsmobile cutlass. I suppose nearly any type of semi luxury car would work, cadillac lincoln whatever. I put this under my rubber floor mats, remember no carpet yet. Its now reasonably quiet inside the car especially considering I have a 2 1/4" downpipe, motorcycle muffler, ported head, ported intake, and the air intake draws air through a 3" tube which goes to the rain tray/cowl. This thing was painfully loud before...literally. Now its nice to drive. Once the headliner is back in, the carpet is done and the exhaust has an effective muffler It will be luxury quiet. I also have stuffed all open dead space in the back of the car in the hatch and by the wheelwells with foam chunks.

Great info.

I really like the last one that speaks about using some commonly available, and cheap, sound deadening materials. Right up my alley as the funds just go too dang fast (a lot faster than my car, which is still waiting to be put back together).
I will try to remember to get photos and post progress.
