Title: Engine Identification
Post by: Blackcoupe230 on September 24, 2022, 04:35:34 PM
Hello, this is Dana Robinson. I have a 1935 PJ Deluxe Business coupe. I have been a member of the Plymouth Owners Club since the 1990's I was at the 1998 National meet in Plymouth MI. with my car. After not starting my car for 21 years, its now time to do some major work. I have a couple questions. #1 I know my car has a Dodge car engine 230 CI, number on the block is D24-22492. From what I have read D24 was used in 1946, 1947, & 1948 cars. Does anyone know exactly what year it is? I have been trying to buy cap, rotor, plugs ect. to try and start my car and have a hard time getting the write parts. #2 When I bought my car I got an extra engine with it. It doesn't have a block number, its blank. From what I have read its an after market engine that you could purchase when yours wore out. The tag on the block says "For Parts Specify Model 219" Does anyone know what size or year this engine is? I will have to rebuild one of these engines. Thanks for any information. Dana Robinson

Someone somewhere probably has engine number break outs for the 1946 through 48 but unfortunately I don't.

With respect to getting tune up parts, it is possible that when the newer engine was installed the used the original distributor, etc. Look at the tag on the distributor, from that we might be able to identify what year and make you should tell the parts person to get the rotor, points and cap you need.

Blackcoupe,
For the correct points, cap and rotor, you will need to know the model number of the distributor.
I assume it is an AutoLite.  It will have a tag on the side of the distributor base telling you
the AutoLite number.  NAPA Auto Parts or one of the on-line MoPar sellers will have these parts.

Blackcoupe,

I looked in an old (1954) parts book.  Firstly, it said that Dodge engines from 1946 through 1948 - and maybe into early 1949 - used the D24 designation for engine serial numbers and automobile serial numbers.  There was no "reset back to zero" for each year.  It stated that the 1946 year engine started with D24-10001 and continued throughout the D24 models.  You would need to talk to someone with intimate knowledge of Dodge serial numbers to find what year your engine was build.

Also, all D24 engines use the same distributor and distributor parts.  This 1954 book called out these numbers:  distributor model #IGS-4207A;  cap IGC-1107S;  rotor IGC-1015B;  points IGP-5028ES.  These are old AutoLite part numbers.  I'm sure they have been superseded and the AutoLite parts might not be available.

If your local NAPA Auto Parts does not have what you need, I'm sure an on-line seller, like AMS Obsolete, can help you.

Thank you Bill & Tod. I did get a picture of the distributor tag and it is an AutoLite The Napa man sold me points and cap for a Dodge in the 50's that looked like mine. The points for the 46 and 48 were opposite of mine. I didn't know there was a tag on the distributor at that time. I will check with Napa with the AutoLite numbers. I tried to look up AutoLite numbers and didn't come up with anything. The Information that for the serial number says D24 1946 Dodge cars started with serial number 30,645,001. My Number is D24 22492. Doesn't Make sense to me. I will get in touch with the 1946 tech adviser. I have an extra engine that does not have a serial number. It has a tag on the block that says "For Parts Specify Model 219" Does anyone know how to find out what this engine is. I have read you could purchase a new engine for your car when yours wore out and they had a tag on them. I need to rebuild one of these engines and I'm trying to find out what engines I have. Thanks again Dana Robinson

What is the AutoLite number on the distributor? We might be able to identify what car that distributor was originally fitted to.

I can't really help you regarding the D24 22492 or "Model 219" engine numbers at this time. I will try to find some time to dig into my references.

Chrysler Corporation Splash Proof distributor. Part no 1546755
AutoLite No IAT-4101B Serial No 3J0G2221

I did get in contact with Michael Warshaw 1946-1949 Technical Advisor and owner of www.moparpro.com
He said my engine is a 46 47 48 Dodge 218 CI not 230CI
He said the distributor was not from then and he is trying to find it also.
I did get points, rotor and cap from a few different auto stores.
The points matched up with a mid 50's Dodge and the cap and rotor they matched up with a 63-64 Willys
My neighbor (78 years old) used to own a Plymouth-Dodge dealership years ago. He said if I had a 35 Plymouth
201 engine in my car, the points, cap, rotor would be the same as his 46 Willys he owns now. That's way I kept throwing in the Willys at the auto store when they couldn't find anything. Thanks for the help Dana Robinson

My copy of the 1946-54 Plymouth Factory Service Manual shows that AutoLite IAP 4101 A-1 with a Chrysler number of 1233566 was used on the P-15 Plymouths (1946-48). Your Chrysler and AutoLite numbers are slightly different so not for Plymouth but probably for the same general era.

It sounds like you were able to find points and a cap that will work. That is great and you will want to record the current part numbers for the next time you need to replace them.

Thanks Tod, Yes I did record the numbers from the points and cap. Even saved the box ends.
Every little bit helps. Still can't start my car. Timing chain is loose, and have 0 compression in 3 cylinders.
Michael Warshaw said I have stuck valves.
Like I said its time for a rebuild.
Thanks Dana Robinson
