Mystery Pipe...

[Guest]

Hello, all

I was rooting around in the front of my recently acquired 964 Tip (RHD).

Above the battery, two pipes pass through the inner wing. One is from the intensive cleaning fluid reservoir and is plastic with braided reinforcement.

The other pipe, in my car, passes through the wing close to the abovementioned. It looks meant, with a neat rubber grommet. It is transparent plastic with no braiding and, erm..., it is not connected to anything within the car. It just ends in free space!

It does not smell of anything smelly like fuel or washer fluid. I can blow through it, and it sounds as though it exits under the left wing somewhere.

Any ideas what this might be (or have been) for?

My car has some dampness in the area of the battery, and I wonder if it is due to this tube, although I suspect that it is just that someone spilled fluid when filling the internal washer reservoir.

Are you talking about the battery vent pipe?

Well, I did wonder if it were a battery overflow pipe. I remember that the battery on a 944 I once owned had a dump pipe extending from the original battery. It became redundant when the battery was replaced. It always looked to me like a liquid drain pipe since it ran downwards from the top of the battery, but it could have been a gas vent.

On my 964, the pipe would run distinctly upwards from the battery before it passes through the wing, so it is not going to get rid of any liquid acid, but it could have been to vent gas, I suppose. The battery in my present car was not original, so I cannot be sure how it was originally set up.

I now have a nice new sealed Bosch battery, which I hope will need neither venting nor any other attention for years to come! So, I think that I will seal off the pipe in question in a neat (but reversible) manner.

Some battery vent pipes also connected to small container on RH inner wing.

One assumes that Porsche had problems on older cars with the battery dropping thru the rotten floor! BTW, Holden Classics do a battery acid mat that can be put under batteries to soak up any spilled acid.

You blew the tube??? How are your lips this morning...........[&:]
