G'day Eric,
I had an 81' Vanagon L that I bought new. It was actually pretty quiet, but then it had no miles on it. I only owned it for the first 60,000 miles, so who knows once it got on in years. I did ditch the factory Continental tires in favor of a set of Pirelli P700's the first month I had the car though, and that improved ride and quiet a bit. Remember those tires? They were pretty good in their day. And this 87' was horrid when I first got it, but that was because it had it's original shocks and a set of house brand tires that had been on the thing in storage for something like 12 years - bricks more than tires really. The mileage on this one is low though, and her suspension/ steering is still tight so with new tires and shocks she's a bit nicer than the 81 was - but of course we didn't have 16" alloys and XGTZ4 Michelins back then Wink
I'm thinking of replacing the seals at both front doors and side door. The existing ones are fine, but I'd just like the doors to close as snug and tight as I remember them on the new car.
The biggest tangible difference between the 81' and 87' for me is the smoother idle, greater horsepower, and automatic transmission on the 87' that gives it better overall drivability. And of course the jump seats and table are pretty clever. But I liked the thinner 81' mirrors better than the boxy electric ones.

I have an 89' Wolfsberg 'Whitestar' and an 82' Diesel Westy. I'm sure you can imagine the difference in sound! Even without the engine noise the front doors and sliding door in the 82' just seem like they are made out of thinner metal. They just do not have that beautiful low deading 'thunk' sound that my 89' has when I close the doors. I am going to try the sound deadening product on my 82' to try and quiet down the symphony of noises taking place behind the front seats. I don't think there is a noisier car than an old westy.........diesel!!!

Do you folks know whether the later model versions have this stuff going on already? I have an '87 Westy that I wouldn't mind quieting down, though it's not too bad as of now. Question

Yeah, missed it Embarassed , I think that's the stuff, that should stop alot of noise. My 87 Westy, when i bought it, it had the passenger door step rubber missing, man those four little holes let alot of noise in. First thing I did was order a new one from GoWesty.

Tin can sound is gone. And the van does feel more solid. Laughing I can still hear the long standing squeak in my front end though Rolling Eyes But I think I need to fix that problem rather than cover it up. Its been cold as hell recently, and I haven't had a whole lot of time to complete the job. Unfortunately I havenít progressed much past the last photos I posted. The job will be on hold at least until I get that rust out of the picture. Rolling Eyes Keep ta posted.


By doing your front doors does the eDead keep water off of your door panels? Is it water tight?

Yes, with this you don't have to put back the plastic "moisture barrier".

Mighty... That stuff looks great. Are you just laying it in the panels, or are you using adheasive?? Any concern about moisture trapped within or behind it?

Sorry to reply to an ancient thread but it just got added to the stickies today so it seemed like a good place to post my experience yesterday. I picked up some of that tar-based roof repair stuff (about 1/16" thick, 6" wide, comes in a roll) for $15 at Home Despot. Put it on the rear hatch panel inside, and voila! HUGE difference.

This stuff is WAY cheaper than B-Quiet. I was initially concerned about offgasssing from the tar-based stuff but (1) B-Quiet's mid-grade stuff is tar-based, and looks like the exact same stuff, and (2) any outgassing won't get past the vapor barrier anyway. I picked up some 4-mil clear plastic for that ($12).

Granted, I'm not doing the whole floor and stuff like some... just the noisy doors. One roll is plenty for that.

I also looked at the Frost King duct insulation that some have used. It is very lightweight-- I suspect it would not work nearly as well as the heavier stuff for sound deadening.

What is the SKU number so the rest of us might be able to find it, please?

Okay, I can't stand it any more. All you guys getting your vans quieter is even making someone as destitute as me, consider doing something about it Smile

Mine is a plain vanilla van, with rubber floor mats, so if you think your carpeted vans are noisy....... oye! I rode in a friend's van once, years ago, that had carpet, and was stunned at the difference.

Here is the rub. Buying some stuff and putting it on doesn't seem to stress my skill set, but how are you folks getting the door and hatch panels off and back on? It seems to me that after 25 years, if I try to remove those things, every one of those little plastic 'doo dads' is gonna break, the panel will crack or bend, and although it might make the van quieter, its not gonna be all that pretty anymore.

What's the secret to getting those panels off and one in one piece? and for the doodads that break, what are you doing to replace/repair/make ammends? Please?

Thanks,

Mark

I trashed the UPC but on the label it says "Protecto Wrap Quick-Fix Roof & Gutter Repair Tape". It's next to the roofing/flashing stuff. It has a foil backing that faces out, and some very strong adhesive when you peel off the paper. I wouldn't put it over anything you might need access to ever (e.g., welded seams and such). I went for about 75% coverage.

I have a set of these for pulling the panels off:

I broke two or three clips pulling off the back panel but maybe others are more skilled. I have seen the rear hatch ones for sale at Bus Depot.

Your laying down of sound deadening material is way better that mine. Your cuts look sharp!!

Question about the doors. Thats my next step. Why did you put it over the plastic and not behind the plastic? I thought I saw a post that said to do what you did to achieve more dampening affect, but I cant find it now. I was thinking about doing it on both sides, but like you I go overboard.

Thanks,

Jason.

Thanks Wink I'm an architect by trait so anal retention is my vise Rolling Eyes Laughing I spent wayyyy too long on it.

Yea I kinda did the doors the wrong way. I was reluctant to remove the factory installed plastic sheeting. So that was my only option. If you remove the plastic in yours, or its already gone, put your sound deadening material on the inside face of the actual door skin. You'll get even better results. Also you wont have to worry about your speaker leads grounding out on the material.

Good luck

Good luck

Just to chime in a bit on the plastic sheeting or vapor barrier. I discovered that the PO (or rather his mechanic) removed the plastic sheeting on the drivers side when I was doing a bit of sound deadening. I bought some painting drop cloth plastic that was rated for moisture and some heavy duty double stick tape. A little bit of creative x-acto knifing & patching and it was all sealed it back up nicely! I've had to take my door apart several times due to some powerlock gremlins so I'm good at it now!! Just a thought!

Thanks,

I tried to pull the plastic off and it seems like I might be able to pull it off and save it. If not I will use tencentlife's suggestion.

Cheers,
