Traveller, thanks for your reply!

I looked up your suggested part. According to the parts diagram, it would appear that the mentioned part, 993 602 121 00 is some sort of gasket (breathable or vented?) which goes between the distributor and distributor cap. It is not a hose which interconnects with the oval distributor openings (which I suspect were originally intended to be used to visually see the belt for inspection). I'm thinking that this gasket implementation differs from the original hose ventilation implementation but if doable is the preferred over the hose ventilation implementation.

Perhaps the gasket implementation is the final Porsche solution to ventilation of the distributor?

Do you (or anyone else) perhaps know:

- How does one identify or tell if the distributor in the 964 would support the gasket ventilation solution? Is this doable for all model years?

- If the gasket solution is doable, does that mean the hose ventilation patch can be removed and thus simply return the hosing to ventilating the rear signal housings?

- I presume that both distributors would have this gasket?
