    If you sqwuint you can see past the purple color, but what is that hole for below the vaccuum advance in the valley cover? I've never seen one...of course I've never seen a purple nailhead either.

    Funny how he says "No internal damage has been done that I have seen". How would you see internal damage w/o taking it apart?

    Oh! Now I see how he knows. He looked through the hole in the timing cover. :grin:

    That's for hte downdraft tube -

    pre-PCV systems used this to evacuate gases from the crankcase.

    He claims it is out of a '65 Rivi. Seems to be a lot stuff that doesn't make sense on this listing. But I like the word LA-Sabre...catches alot more hits on the searches that way.

    Thanks for the pic. Explains it all.

    slober tube

    I think thats what they call that. I have seen something like that on some old vetts at my mechanics shop.
     
  6. Adam is right on the money (as always).

    That's the hole for the road draft tube. The government made car makers stop using them in 1964. Of course, the car makers spun it to read "with the new PCV system, no spots in your driveway."

    Is the other end just open? or does it somehow work its way into the exhaust?

    That must not be a '65 motor then, or at least not the valley cover.

    It works like a venturi effect at the bottom end. It runs all the way down to the undercarriage of the car and is cut at an angle to catch the wind of the road while driving - sucking the gases from the tube. It doesn't work well when you're not moving :grin:

    I leaned the hard way

    Rick,
    I bought a set of Valve Covers and a Valley pan off Evil Bay, The listing said from 1959 to 66. There were no pictures on thelisting,When I got them in the mail I was really bummed because the Valve Covers had a Breather cap on each cover and a large hole on one of the valve covers the valley pan had the same hole that you have on your picture! :mad: , I wrote back to the guy and he told me I did bot know what I was talking about and said that they used that set up up until 1966. I sent him a picture of of a 1959 Nailhead and showed him the difference between the early Nailheads(pre 63) and the newer ones(64 and up). I never got a response back! That is what I get for buying something off Evil bay with no pictures!
    So I am going to offer them up to anyone running an old Nailhead!. I could sut the tube off and make a filler plate to patch the hole up and the do the same on the Valve Cover but I want to see if anyone can use them here on the board first.

    We called that tube the undercarriage rust prevention system :laugh:

    I considered bidding on that motor but there are just too many questions that go along with it.

    What the heck are you talking about???

    Isn't kind of weird that in the title it says not GS, lesabre. But a guy asked him if it would fit into a 63 lesabre, and he said it would bolt right in??? :blast: :laugh:

    I Think....

    I Think that from what I have researched that they stopped using that tube in 1961 or 62.
