This is my first time under the car (and the first time under a 914 or even a VW) so I could use a little help identifying some things.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403419060.1.jpg)
There is an unattached cable on the right side.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403419060.2.jpg)
There is also another unattached cable above the shifter.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403419060.3.jpg)
The car has an ANSA exhaust. I'm not sure if these two pieces are suppose to meet.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403419060.4.jpg)
I wonder if this hole should have something attached to it?

It looks like your heat system is pretty much missing!

Thee cables should connect to heater valves that are opened by the lever just to the rear of the shift lever. If you have heat exchangers you need a number of parts to make the heat work.

Air circulates around your exhaust in a heat exchanger.
When heated the air is blown into the two tubes which run inside
your longs. The other ends of the longs have flexible tubes which direct the air up through the dash into the blower plenum. Looks like you are missing
fans, tubes,flapper valves, etc.

Front air system

Rear air system (fans missing from pic)

Be sure your car still has the heat exchangers before you start sourcing parts. That would be the big ticket item. Everything else is cheap and easily sourced.

first two pictures are cables that should attach to heat bellows / valves that let heat into those big holes that run into the car cabin (the last picture).

There should be two of those big holes.

Heat exchangers surround your exhaust "pipes" that connect to the valves.

I see your oil cooler so I assume the motor is in.

DO NOT drive this car in this condition. There are many pictures here to show how your exhaust needs to be setup.

The holes into the cabin will allow carbon dioxide into the car cabin - you don't want that.

Without the fan motors on I would think it would be pretty tough for the exhaust gases to get to the cabin. It's about the most convoluted path invented.

What did you expect, it's German. It has 10 parts when 3 would do. (IMG:style_emoticons/default/av-943.gif)

That big tube in your last picture is the warm air path to your passenger compartment.
So lingering exhaust gases could get sucked in. In the short term just close them up with duct tape.

If you'd like, I could stop by after lunch today.

The FAN MOTOR, I believe you are talking about, really only blows air when the car is idling. Older cars had 2 outlets on the fan motor under the relay box in the engine compartment. Later fans only had 1 outlet on the fan and you could add a splitter to go to both pass and driver. I stuck with the 1 for me, the driver.

My fan works, but the engine is running down the road at 3000 rpm, so it over takes the electric heater fan. It turns on when the red floor lever is pulled all the way up. I only use the bottom dash lever when it is cold.

Yes, I'll make sure I seal off the openings until I get things sorted.

Right heat exchanger. It's pretty loose. Not sure where it attaches to.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403458533.2.jpg)
Left heat exchanger. Doesn't rattle as much as the right.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i237.photobucket.com-17475-1403458534.3.jpg)
Another picture of the heat exchanger and what I think is the J pipe. Not sure why they don't line up.

Another shot of the driver side.

In the engine compartment behind the driver.

hi,

look at the diagram I posted before..

it looks like you are missing both heater control boxes

plus on the passenger side the branch pipe

both branch pipes also connect to the bottom side corners of

fan assembly housing .

Some pics of the parts as they go together:

A common patch for the rattling exchanger is a stainless steel hose clamp at the rear of the "wrapping".

I need to start looking for the stuff I outlined in green.

Part of what you outlined is the forward of the pipes up to the head. (IMG:style_emoticons/default/wink.gif)

You have the tube that runs from the exchanger to the flapper valve. In my pic it is shown attached to the valve, but you already have it.

There are two styles for the right side, and three for the left side.

Early on, the left-side piece bent down under the shift rod. Starting in 73 with the side-shift linkage, the piece then bent up to go over the rod. (The right side stayed the same.)

When they went to the 75+ exhaust, the pieces changed shape to fit the new exhaust.

The older style, as shown in your pic, has two (I think) screws that hold it onto the heat exchanger. Those go through weld-nuts on the edge of the "wrapping" part of the exchanger. There is one or two screws on the inboard edge of the tin piece that go into bosses that stick out of the side of the crankcase.

Sorry, no pics handy.

I'll get the car back up in the air and get some pictures specifically of these parts.

If you want to drive it without heat, you can use a couple of spray paint lids and hose clamps to seal off the body connections until you can put the entire system back together.
