[IMG]I was putting in the fix for the flattened vacuum splitter this evening and saw the item in the photo. It looks like the air supply used to keep the taillights from fogging on the 964s. Is this a useless appendage now, or is there a hose missing? I didn't see any spare hoses back there.

TIA.

 

Are you talking about this bit?

 

Hi Pete,
That looks like the port for the distributor vent hose. It is easy to knock loose while you are working in the engine bay. Take a look for a stray translucent plastic hose.

 

supposed to vent to the distributors, removes "electrical ozone" that harms drive belt internal to distributors. e

 

Pete,

the others are right. Here is a view of that tube connected to the rear blower and on the other side to the double distributor:

 

Thanks everyone, for the help.

How do you draw the arrows and circles? Obviously I am not a Photoshop expert and the text was the best I could do in Photosuite.

 

Hi Pete,
May want to check your distributor out. When I bought my car the hose was missing and the distributor had gotten lots of moisture into it. When I went to do a tune up I found the bearing all rusted and sloppy in the second distributor. Had to put a new distributor in the car, luckily it was covered under the extended warranty that came with the car.
Does anyone know if there is a maintaince schedule for lubricating the distributor bearings?

Thanks Jack. I think that hose has been missing for a while. I seem to recall noticing the bare nub for the hose when I was concour prepping last summer, and then forgot about it.

There is also the issue of the distributor belts also.

 

Thanks to the help above, I hunted around the distributor and found the tube, hiding under a bunch of other wires. Because it looks different thatn the picture Toga posted, I am posting one here. I will check out the distributor, as I think this hose has been off for some time.

 

Pete, be sure to check the black plastic, snap-in connector at the distributor as these have a tendancy to pop out as well..

 

Mine fell off as well....can someone please help me figure out where the other end goes. preferably with pics...
thanks,
Steve

 

This was one of the many upgrades from the 964, which did not have the venting hose, resulting in the degradation mentioned above:

The thread has some excellent pics and diagram for reference

 

thanks, now I see why I couldn't find where the other end goes...the nipple that goes into the distributor must have fallen out as well.
Thanks for the quick reply!
Steve

 

Would'nt this vent release ozone whether the hose was connected or not?
must be useful or it would'nt be there right?

 

I'm assuming that there's a vacuum effect (Bernoulli principle?) from the larger hose that helps draw the ozone out rather then having it passively vent just via the vent.
