On Saturday late afternoon I got a call from an elderly friend and mentor who was in an agitated state. A T which he is donating to the Club's museum had suddenly sprouted numerous problems just days before it is to be picked up and he could now not move it across the street to the convenient pick up site.
Sunday I drove through heavy fog (it's been unseasonably warm these last few days) to Lenny's place and together we set about to tame the unruly beast.
With success ours, it was time to move the T across the street. One of the repairs involved removing the carb. The hot air pipe was not yet back on. "Lenny, don't you want to take a second and put the pipe on?" "Oh, we're just going across the street."
Um, OK, Lenny.
Well, it started and ran a bit rough as a T can when it is only about 40 degrees, until the engine warms up. The engine never really smoothed out and ran poorly (read crappy) as it crossed the street and was backed into the staging area.
As it was crossing the street I noticed that the intake manifold elbow was coated with heavy frost and it was even starting to cover the front of the carb. (Remember the heavy fog? The air was quite humid.) I thought that some of you might enjoy the following picture.
Take Care, Bill
Been there, done that, got the picture! Now that is a lot of ice!
Last year on the way to a parade my car started to run progressively bad, we just barely made it to the staging point. When I got stopped my carb looked just like above but about three minutes later the ice melted and the car ran just fine the rest of the day. I will no longer run with out a heat pipe.
Only time I ever hat this problem on any of my T's is when I ran a cast iron intake without a heater tube. I have never had this problem since I installed an aluminum intake.
I thought my exhaust manifold studs were the wrong ones because they were so short but I'm ok now that I've seen yours are the same as mine, Don
Has anyone ever seen icing with a Wilmo or Anderson. I drove my first T in 1945 and have never seen it on any T. I drive one of my Ts to town ever morning in pretty low temperatures.
William's very good picture above sure proves that it happens.
If I can post it the pictures below was taken by a tourist up in Wyoming one time when I got caught in a blizzard. My coupe did not ice up as far as I know, just kept plowing through the snow.
Another picture if I can post it. I was at 2 miles above sea level. but this picture does not count because the center door has an Anderson.
This picture (if I can post it} Was almost 14,000 feet. It does have an aluminum intake. Again never any icing that I know of. I guess we are just too dry.
You will have to move the first two pictures around with you mouse to see the coupe. I don't have a clue why the pictures came out so large.
In 1989 We had the MTFCA National Meet at Estes. I believe that it was the largest all MTFCA tour that has ever been put on. We had 227 Ts. One of the routes was over Trail Ridge (the picture above} I was the wagon boss and I am sure that if anyone had icing I would have heard about it. The picture below will show part of Trail Ridge. Its show just above the top of the T. That part is only 1/2 the way to the top.
According to the attached chart, the highest risk of carb icing occurs when the ambient temperature and dew point are nearly equal and the ambient temperature is between 25 and 60 degrees F.
A bit smaller
Still a lot of snow!
I had this often even in the summer. When I drive richer then if had less Ice on the Manifold.
But since I but a “hot air pipe” on it the problem is solved.
Attached the Foto of the Pipe You will get it at Snyders T-4582 $12.95
I'm running an Anco Hot-Spot manifold with a foam air filter on my'26 TT without ice build up.
I just realized that if you could quickly remove that manifold you could use it to chill your Christmas cocktail!
Have a Merry Christmas!
