Oil Leak from Dip Stick Tube - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

A vehicle just purchased which had the transmission services just prior to collection has an oil leak from the where the dip stick tube goes into the box.
At the time of service a new tube was installed.
Not be overly mechanicaly minded what is the best approach to stop the leak ?
Assistance appreciated...

What make, model and year is it? Most of them have an O'ring where it goes into the transmission. Fluid runs out, so catch it with a pan, probably about 2 qts. The refill the trans to the marks when the fluid is hot to the touch. Otherwise when the fluid heats up, it will expand and leak. Also the shifting can get erratic.

Not exactly sure of the box. It's in a 1932 roadster, bolted to a 302 windsor.
Three (3) speed box.
O'ring is the likely problem. This is what thought was a possible.
It's dropped minimal oil as yet as it's only run about 10 klms since service.
Thanks

That more than likely has the O'ring. Would like to see a post of the roadster. If you have/a picture/s, post in the showroom forum. We'd like to see it.

YES!!! PHOTOS!!!

I had a similar problem in a 1932 Ford model B. I inherited it from my grandfather who had bought it for cheap from an estate sale in Florida. It was in dire need of fender and other body work, the wooden box required a restoration and for the life of me, I never checked the oil when it arrived.

I went to drive it out of the garage, up a 5% graded hill so I could get some sun on it to melt the snow from the night before. It stalled out going up the hill, I'd roll it back down, it would start fine and I'd try again, and again. I did an oil change. Turned out I only got about 1/2 quart of oil (think molasses), the rest had turned into sludge that I could grab with my hands. My guess is that the oil was 50+ years old at least with a lot of miles on it.

One of the things I loved about the ol' truck, was kicking my wife out to fuel it, as she was sitting on the fuel tank filler and had to remove the cushion!

After I flushed it all out and refilled the crankcase it ran great, but oil leaks were everywhere of course, the O ring was one culprit. I have photos, if I can locate the box they're in I'll scan'm and post them up.
