View Full Version : What Is This?

Dan ~ dancoresq sent me this email along with a picture regarding something that broke on his '60 430MEL engine. Here is what he had to say, followed by the picture.

"I have a question for you. I had something - a metal tube - break in my car (60 MEL T-Bird) and I took a few pictures of it. I am not sure what it is that broke but could show you a few photos and could describe it. It seemed to spray oil when gave it gas and the valve on top of it is looks like the an air valve on a tire. It sits in the center of the back of the engine (near the bottom of the windshield). The air valve is whats throwing me off as I don't know what would have that as it's top or if a previous owner rigged something up and its not the real top. It did just happen (at night) so while it looked like oil, I do guess it could be some other kind of fluid. The car still starts and drives although I only moved it back into it's garage."

I think what broke is that copper tube with the white circle on its end at the bottom of the picture. Was that hooked to the back of that flange with the bolt with yellow threads on it?

Every once in awhile this topic pops up. It is a transmission test tube, used by the factory before delivery.

It goes to the transmission and it serves no purpose. Most Squarebirds do not have one at all. Others may have one that is disconnected.

I believe John Byers (byersmtrco) took this picture of his '60 convertible:

Hope this helps. - Dave

Thanks, Dave! I remember this being talked about before now, but did not remember that when Daniel asked that of me in email. I gather, from the looks of it, that the tubing broke off from the back side of that connection on the flange. I gather it would be okay if he were to either try to hook it back up, or cap it off? Apparently, from what he said, when it broke, he experienced it leaking what he thought might be oil, but was probably transmission fluid. I will pass this information on to him and thank you for it.

Yes Ray, tell Daniel that it's ok to remove and discard the tube from his trans and plug the hole.

What is pictured by Mr. Byers is the what broke and it does look, in daylight, like transmission fluid and not oil. Very good news that it can simply be capped off. As a temporary fix to stop the leak (a significant spray, actually) and to move the car back to the garage and seeing that there was excess tubing that could be pulled back through if necessary, I did clamp the tube that's pictured with a monkey wrench and, as stated, the car seemed so sound fine while running. Now I need only to cap it permanently. Always a nice to hear a fix is an easy one. As always, thanks for the help.
