    I never worked on Chrysler engines like this. I know  in the 29 DB the engine is Continental.  Or at least some of them.There may be some made by  Chrysler too. I do not know. There are bloggers on this site who may know for sure and will be able to assist you. The main point is engines of any type do have some sort of seal at the back of the main bearing. I have seen oil slingers in that area, and some bearings designed in such a way, allowing the oil to pass the bearing in special groves to allow the oil to flow back into the sump At this point I suggest you check the oil pressure and compare it with specs if you can find it. In my Dodge Senior six the oil pressure after starting is constant 40 lbs regardless of RPM. Worn bearings, rod, main or cam will cause oil pressure to drop,It appears to me the rear main is specially designed as a combination of bearing and seal slinger . Bearings in those days were poured babbit and who knows what. I am hoping you are not looking down the road to a rebuild.   

    Note following reference for Senior six but only used in some cars and 29-30 trucks. Smaller wheel base trucks used the DA-6 and were built by Dodge Bros.

    the most notable different was the length of water jacket.

    I'm not sure that is correct as gearing is what is hindering top speed on the big trucks. Yes a poor running engine can be a factor, but only a factor

    I’ve learned what the warranty tag on my 29 DB 3/4 TON truck indicates. These old truck were not intended to be used for fast travel. They were used as an utility of moving goods. When you have a 5.11 rear end ratio you can not expect cruising in traffic at 55 mph. Some folks have invested in the “Mitchell “ transmission assist to get better top speeds. 

    You just have to enjoy the journey and ignore the impatient divers.

    😐 I am looking for clincher rim to fit a 1928 Dodge Senior 19 inch wood wheel. Tire size is 600/650 x 19 , The width is 4 and a 1/2 inches wide . If measured across diameter  it will be 21 inches. It will have 6 lugs. The ones from Graham truck will likely be the same. Please PM me. 

    Got a picture?

    Not sure if the 72’s were the same as the 75’s but mechanically I don’t think there was much difference. Here’s a couple of pages out of my 75 manual that may help. There is no rear main seal, the first thing I would check is that the drain passage isn’t block any way it is a bit late here so I will leave you with diagrams to study Cheers Ben

    Per attached pic item number 15 is rear main bearing oil passage. The rear main drains into this sump and If the bearing flow is to much to drain into the pan the sump overflows to bell housing area and drips thru hole.

  5. My 29 DodgeBros DA6 engine may be similar. There is a reservoir at rear of engine. It has a slinger that slings oil at rear of engine. Excess oil should drain to the oil pan thru a tube. Excess oil will drain out. There’s no seal at the back of the reservoir .

    These engines are notorious for dipping oil. Even my rebuilt engine dips oil.

    I found possible causes to be: excessive oil pressure, improper installation of rear oil pan seal, and worn rear main bearing.

    I ran an engine in my truck with unknown history, but it did run. The rear bearing was so badly worn that the oil  over flowed and poured out of rear of engine thru hole in bell housing.

  6. I believe Dodge didn’t supply floor mats for 29 trucks but with the cold weather coming I have eliminated some cold drafts.

    I got mat material from Restoration Supply. Note the edging material. I used 5/16” rubber tubing. The trick was to split with single cut. See pic of wooden block with knife edge. Placing the 3M mastic was a bit messy.

    I also placed a cocoa mat on the firewall. There was a material placed there by factory. Does help quite engine noise

  7. Interesting find On DB Club site of invoice listings. http://www.dodgebrothersclub.org/pictures/Dealer_Invoices/Searchable PDFs/

    Here is a 29 Graham Bros DE chassis with a DA engine. “H” code is DA 6. Guess they were just cleaning out their warehouse of parts. Only things to make it a GB truck rather than a DB truck would be the badging of radiator and  hub caps.

     

    These are searchable PDF files that can be down loaded to Adobe PDF files.
