JRA Posted June 9, 2014 Share Posted June 9, 2014 Hello Everyone, I just bought an 1929 Hudson and I do not know to check oil level. The engine does not have a dip stick, but a sort of glass tube. This tube seems to be empty. How does it work? Thanks, JRA Link to comment Share on other sites More sharing options...
paulrhd29nz Posted June 9, 2014 Share Posted June 9, 2014 Welcome to the ownership of a Great car. 1929 is the first year for Hudson for an electric oil level indicator. You activate it buy pushing the button on the bottom of the instrument cluster. When depressed, it turns your fuel level gauge into an oil level gauge.( It may not work check the wires behind the gauge ). All the gauge will read is empty or full. I do not rely on the gauge at all. I have a 3/8 wooden dowel that I use as a dip stick that I keep in the car. When inserted into the OIL FILL hole, It should read oil at 2.25 inches from the bottom of the dowel. When the pan and troughs are properly full. Use a good multi grade oil, 15-40 is what I use on all the old cars.What body style is your hudson? We love pictures on this sit! Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 9, 2014 Share Posted June 9, 2014 Someone must have installed a sight glass. When the oil is full you should see it in the glass tube. Drain the crankcase, fill to the correct level, and make a note of how much oil is in the glass. Then you can tell at a glance if you have enough oil. Suggest you also get a dip stick as paul did.

JRA Posted June 9, 2014 Author Share Posted June 9, 2014 Thanks Paul and Rusty. It is a Standard Sedan, with wooden spoke wheels, dual sidemaount and trunk. I am enjoyng a lot this car. I am wondering if it is going to be faster than my 1929 Chrysler 75...See pictures attached. You can see the glass tube for oil level indication. It seems to be original. Once it is cracked, how can I replace it? Where can I find such glass tube, is it a special type? Is there any special seals at its ends?

Rusty_OToole Posted June 10, 2014 Share Posted June 10, 2014 (edited) It is too high to be an oil level sight glass. Does oil pass through it when the engine is running? It might be a visible signal that the oil is circulating. If not that, then I don't know what it is for.Is it possible there was a rod in there with a float at the bottom, to indicate oil level?The Hudson Super Six was considered a fast car in its day. So was the Chrysler, its high compression engine was state of the art. Hudson won many races in the US, while the Chrysler was one of the first American cars to finish in the money at the LeMans 24 hour race, and in other races in Europe.If both cars were in tip top shape it would be an interesting race. The Chrysler 75 was supposed to have a 75 MPH top speed but they were usually a little faster, between 75 and 80. I don't know what a Hudson would do but they went very well. They never tell what body style but I would say they tested the roadster. A sedan would be considerably slower than a roadster.If I had to rank your cars by speed I would put the 51 Plymouth first, then the Chrysler roadster, then the Hudson sedan, then Dodge, with the Chev and Jeep fighting it out for last place.

zeke01 Posted June 10, 2014 Share Posted June 10, 2014 There should be a float in the oil pan with a thin rod attached to it. At the top of the rod there should be a small ball attached to the other end of the rod. This ball moves inside of the tube and indicates the oil level. There should be a plate on the side of the block behind the tube with marks to indicate oil levels. Link to comment Share on other sites More sharing options...
JRA Posted June 10, 2014 Author Share Posted June 10, 2014 Thanks Zeke. Do you know where I can buy such glass, once mine is cracked? And how can I replace it? How can we seal the ends of such glass tube? Thanks, JRA Link to comment Share on other sites More sharing options...
paulrhd29nz Posted June 10, 2014 Share Posted June 10, 2014 JRA You can get the glass tub from a Medical supply company and have a glass shop cut it to length for you. Cut your own washers from rubber or felt, they go on the top. Do not over tighten the large screw. It sure looks like to me that your float is in the tube. I think I can see the ball.Remove the large screw retainer on the top of the casting, and look down the glass and see if you can see the top ball on the float. If it is in there, try to lift it out. Once it is out, inspect the float and clean it.They stick all the time inside the tube that goes in to the pan and are not that reliable in my opinion. I have many super sixes and never look at the float, I use my own dipstick as described in my first post.PS. A 29 hudson, in good order, will blow the doors of your Chrysler. Get ready to have a big smile on your face. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 10, 2014 Share Posted June 10, 2014 Remember, it is a Hudson sedan vs Chrysler roadster. I think it would be a close race. Both were considered fast cars in their day. Link to comment Share on other sites More sharing options...
JRA Posted June 11, 2014 Author Share Posted June 11, 2014 I think I will try the wooden stick idea to measure the oil level. Paul, just to confirm, considering a stick that goes inside the oil fill hole, is the 2.25 inches mark FULL? What would be the MINIMUM mark? Thanks JRA Link to comment Share on other sites More sharing options...
zeke01 Posted June 11, 2014 Share Posted June 11, 2014 To get the dipstick marks right, fill the oil pan with oil leaving one quart out. Mark your dowel at that point. Then add the last quart and mark again. Worked for me. Zeke Link to comment Share on other sites More sharing options...
