    Puzzling '67S Air Cleaner Assy Port

    Hi folks - My '67 S appears to have an original air cleaner assembly that has a strange 'port' on the bottom, front surface. There is a hole about 2-3 mm in diameter that allows air to short circuit to the clean side of the air filter. The outside of the 'nipple' has no barb, so it doesn't really look like it's intended as a hose connection. What's up with dat?? Any ideas??

    Best Regards,
    Bob

The 911’s initial participation in a competitive event, the 1965 Monte Carlo Rally, was fitted with a 100L tank (#300055). Seeking additional info on earliest 100L tank fitments to 911’s.

    To test the drain for function, overfill with oil...

    I have a hose attached to mine (that allows any moisture or oil to drip harmlessly on the ground) as I previously had an experience with an overfill (oil) situation. Bottom line, if someone stupidly overfills your oil, no hose will allow it to go all over your engine.

    Its a moisture (oil overfill ) drain that should have a hose attached. The hose exits into a "resevoir" that fits through the tinware over the engine oil cooler. The resevoir has a porous slip on base (look like an upsidedown brown hood)

    "Reservoir"

    Thanks for the input! I considered the possibility it was a moisture drain, but never stopped to think that a dry sump would purge any oil overfill thru the breather....makes sense.

    Anyone have a photo they could post showing the 'reservoir' as Nick Moss calls it? I guess it would be a dumb question to ask about the availability of replacements.....

    Best Regards,

    Puzzling '67S Air Cleaner Assy Port

    Hi

    As Nick said it goes to a small metal tube that fits through the tinwork, a rubber valve slides on the bottom of the tube, I have just replaced the rubber valve, it’s the same as a VW Beetle breather valve I got mine from the local VW garage. Its also shown on PET with a Porsche part number as is the metal tube.

    Regards John
