 |
|
OK guys as I mentioned in another post, I tried removing the foam causing my bug to bubble up the paint on both side of the Crescent side intake vents.
Well completely removing the foam is a big jog and I am use you will not get it all out unless you cut the sides of the car.
So all I was able to do was put a small pipe from the vent into the other end in the engine compartment.
Figured maybe when ever I have time I will to the right job.
SO I take the bug for a ride. Damn it never smelled so bad from the exhaust gases, what did I do.
What I did was make a tunnel for the fumes. The Crescent vents go to the cabin and engine compartment. The fumes now go directly into the cabin from the engine.
So now I will be dealing with the Death foam himself. I will foam close just the part that enters the engine compartment.

Sorry buddy, I figured you had used the search feature. 
I can show you how I handled that on my 60, not sure if will work the same, I've never had a new enough bug to have "vents". |

Now you finally know why you were getting labor quotes of $2000.

Yes.....those vents...which I am sure you know....are not air vents FROM the outside...they are air vents that pull air from the sides of the rear window...outward.
To be precise...the overall design was so that when you have the front drivers or passengers window cracked just a bit....the air flows up over the roof liner and down teh back window and is supposed to be sucked out the vents.
Its part of a "draft free" ventilation design.
I do not know how well it worked on the beetles but it worked very well on the 411/412 cars.
Here is more about it.

I always thought they were for the heater/defrost. Either way, I think many folks make “pillows” like the older models to stuff in there when they remove the foam. That’s what I did anyway. Search in the bug forum there’s even a post with dimensions on how to make the pillows.

I always sorta suspected those vents were there, in part, to make closing the door easier (possible). 
But yeah, sucking air out helps blowing air in, important on a car where only naturally occuring pressures are available to provide fresh-air ventilation. (except the supers with fans). |

| Vw made. A triangle piece of foam covered in some sort of material that slotted into the area behind the window. Accessed from the engine bay. |

This ^^^^
VW on earlier cars used left over headliner material to make the Triangular pillows. As stated above they were inserted into the "C" pillars from the engine compartment.
I guess VW thought it would be easier/cheaper to use the death foam instead of the pillows.
A friends wife made a replacement set for his 66. Sadly I have lost track of the pic and the friend.

Yes.....these were part of the defrost and ventilation system. The question i have always had about these vents on the beetle.....is if they actually worked well at all.....as designed.
As I noted....they worked well on the type 4 cars.....the sedans especially. But not quite as well on the wagons. I always wondered why the wagon flow through defrost and vents did not work as well......until the paper board back window duct panel on my 412 two door finally got destroyed. Then the two door system worked poorly as well.
So the gist is that the 411 two and four door sedan came out in 1968 with normal corner vejt windows in front. It had some condensation issues in the back I suppose.....so the next year onward......they got rid of vent wing windows.....and ground a notch into the glass of both driver and passenger side cront door windows.
So when you crack the window just an inch or so.....the air only comes in at,the top and flows through both aides of the headliner.
When you are driving....the two "gills" at the back create a very small suction. They were linked to a "manifold" with slots in it that goes all the way across the rear window from aide to side.
So air comes in the front....over the headliners.....flows down the rear window from top to bottom.....and gets sucked/pushed into the manifold at the bottom of the glass and out the gills.
Its described in the owners manual mainly as a method to create "draft free" ventilation while driving. I'm betting mainly with smokers in mind!
But.....on the wagons.....there was no "manifold" with any volume for holding air.....just a row of slots on each side of the rear glass.....just like the beetles. It did not seem to work well on the wagons....so i suspected it may not have worked well on the beetles either.....but i do not know for sure.
I will try to post some pics later. Ray |

I wonder if the fact you don't have a headliner in your car is contributing to this?

Well today I resealed the very end of the foam, that may solve the smell.
Next will be open the Crescent vents. I have two sets of those so I will just swap them out.
Q- dog, good question. I wonder if the the bars that run around the roof that the headliner attach to have opening in the engine compartment and the like you said allow, fumes in??
This whole venting system is totally new to me. I though the vents were intakes.

| I think it will solve it. Doubt it's as bad with a single centre mount, but with dual dells either side and only inches off the top of the engine bay no wonder it smells, the fumes will go out the air filters and rise up into that opened up area. The inner foam is still better off being gone though. |

Clark it a no win situation.
Unless I take out the body saw remove some slices of my bug on both sides, trying to get the foam out is really tough. The sides of of the tunnel from the vent to the inside of the engine compartment will have foam wall paper.
Your single barrel carb theory is logical
At the moment I believe if I keep the water out it will slow down the progression. Or even cutting out the visible bubbles and keep my fingers crossed. Then find a shop to match the paint.
That said I want to enjoy the car this summer. Cold winter days await me.
My wife and I stopped off at an Ice cream Store on a main road. In 15 mins.
at least 50 to 70 motorcycles in groups stopped for ice cream or just road by.
New and old bikes and they all smelled like my bug. They were enjoying themselves.
I plugged the two original vent covers with black silicone and ordered stainless steel mesh that I was going to install over the silicone to give it and original open vent look. Lets see how that goes.
