    67 BB Dipstick Tube Color

    I am in the process of detailing my 67 L68 engine and note that the Judging manual states the oil dipstick tube is painted semi-gloss black. My tube is currently a natural unpainted finish and appears to have never been painted. I am under the impression the tube is original.

    A friend told me the tube's were never painted. Who is correct? Do I paint or leave it natural?

    Thanks in advance for any help.

    Mine on my L71 is Natural. That being said, I have a 4th edition JM that states natural, I also have an updated 4th Edition that states Painted? I did not receive a deduct for Natural.

      Thanks Bill,
      I think I will leave mine natural as it was. The JM is confunsing on this matter.

        I agree Bill. Natural is correct. The tube wasn't even in the same state when the engine was painted orange in New York.
        The tube was installed at the St Louis plant.

          I did not know that the tube and dipstick was installed in STL! So I guess that the bracket/tube that mounts with a exhaust manifold bolt would not have orange over spray on it? Is this right?
          I think I learn something new everyday on this board! Thanks Michael.

            The AIM shows that the dipstick and tube are listed as being installed at the St Louis plant so no orange paint on the tube.
            The existing exhaust manifold bolt is reused to secure the tube, so, of interest is the fact that the bolt head should be covered in orange paint while the tube is natural. It likely would have a few chips in the paint though from being removed/replaced.

            I've been fooling around with these cars for over 40 years and I'm still learning.

              Here's a pic of the dipstick tube removed from my 43,000 mile, barn find, 1967 L68 convertible. As plainly seen, it's pretty dirty, but no sign of paint, of any color. As best we can tell, the engine has not been apart before.

                Your tube is just exactly as I would expect it to be. I have NEVER seen a known-original big block tube for ANY Corvette that was painted. This includes all years, all engines, and whether the tube was installed in PRODUCTION or sold in SERVICE. I would not rule out that some SERVICE tubes were painted to help "preserve" them while in GMSPO inventory. However, if any were painted, I never saw one and I have numerous NOS big block tubes.

                  I think it is pretty evident that the tube was never painted and is a natural color. How do we correct the information in the JM to eliminate the "painted semi-gloss black " portion so that this does not become an issue on the judging field for someone who followed the JM in their restoration?

                    I just read your original post again and see that I was thinking you mentioned orange, not black. My error.

                    The answer is still the same though. no paint on a big block dipstick tube. Natural finish.

                    I'll try to pay attention.
