  • Oil Leak

    Well, after some, in depth, diagnosis, it seems my "oil leak" is, mostly coolant. I can't tell precisely where its coming from. The car has a pressurized system and an overflow added so I'll have to get it up to temp and have a look see. It is leaking oil from the rear main, as well. I think I'll drop the pan and Plastigauge it. I have a rather steep, long driveway here at The Fongderosa so any leak in that area is going to be exacerbated each time I drive up to the house. My concerns, that I had bought a pig in a poke, have been assuaged.
    Has it ever occurred to you that the sole purpose for your existence might be to serve as a warning to others?

    Carl that is much better news. Remember Model A’s will leak when the front of the car is up on a steep incline.. There is no rear seal to hold the oil in... So make sure before you go dropping the pan.. Also make sure that the oil level is not overfull on a level surface.

      Keeping the coolant level on a Model A has been debated and thrashed continuously. What I have found is, if you fill it to the top it will find it's own level just below the baffle. If you fill it just over the baffle it will stay close to that level. One thing I would advise, when you pull the pan and rear cap, use the tin foil folded in half, pull the plugs and turn the crank by hand, if it is stiff using an extension bar then pull a .001 shim from either side and try it again. I know that this was not done upon reassembly after the babbit fix, which could have negated the fix if it is too loose. Carl, I would also get the 3/8 drain tube and replace the 5/16 drain tube.
      You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

        He said it has a pressurized system???. That would negate the baffle deal

          Carl my truck was jacked up in the front while I worked on the front end and leaked oil a good bit. After I let it down it almost completely stopped. Hope that's your case as well.

            Beau I thought you marked a spot when it went pop.

          I think it's more than the typical Model A oil leak. It left a pretty long, wide stripe up the driveway. I'm gonna go in there and take up the rear main, a tad.

              Feel free to put together a tutorial for the tech section on how to set the bottom end clearances.

              Okey dokey,Will do...give me a bit to format it correctly,the actual process includeds using a measured constant (the tin foil) and feel. Basically you use the tin foil as the "go/no go" while removing shims. Use the "go/no go" in reverse when dressing bearing caps when the shims are gone.

              I suspect The Wiz is, somewhat, like the Loch Ness Monster. There are rumors of his existence but little in the way of hard evidence to corroborate them.

            Too much oil?
            by BillLee/Chandler, TX
            I have heard the story that over-filling the pan on an A engine will cause the rear main to leak. I have no reason to NOT believe this, but I would sure like to understand WHY it is so.

            Anybody with the answer?

            Newby needs a question answered on 29 model a pickup rear main oil leak
            by Adog
            Just bought a new to me 1929 model a pickup. Engine runs fine with no knocks. After a 20 minute test drive and parked on concrete, oil flowed out of flywheel housing. A area approximately 18 inches In diameter. Oil also leaking from left side of engine pan and base of oil fill pipe.

            I have all of Les Andrews books. Question, is it possible to remove pan and the rear main cap for inspection...

            Transmission oil leak
            by Tudor31
            Maybe I shouldn't make any fuss about it, but after replacing the oil pan gaskets and getting rid of the oil leak from the pan, the few drops of oil from the transmission is annoying. The tower has been rebuilt and has a new gasket, the drain and fill plus are nice and tight, but there is still a couple of drops a day (dripping from the drain plug, but coming from somewhere else). The oil is 50/50...

            Significant oil leak
            by Tom Rode
            So I've been driving this car a week or two now, parked in garage it leaks no oil, go for a drive and come back and park it on driveway and it drips oil from the weep hole in the bell housing for 5 or 10 minutes after I return. Clearly leaking while running. Read some about clogged oil return line from the rear main bearing, and other issues regarding leak at bearing and/or seal. Have read other sources...

            Suck it out or let it drip - - oil change
            by Bikerider58
            Sludge in the bottom of the pan is common due to non-detergent oil. If 10 years of non-detergent and 10+ modern detergent oil and engine build; then it seems like the sludge would be cleaned out. I still had a good layer of about 3/8 inch.

            I did not check when the pan was off, but suspect a good amount of oil is in the pan below the drain hole. With the engine tilt it seems like there...

I was 1/2 way between the F and L mark when I headed out yesterday, topped off water in radiator (most of which flow back out under expansion), when I parked for about 20 minutes at one stop noticed more than usual amount of oil under car when I pulled out (about 2 inch across...

            Dip Stick?
            by DaWizard
            I was wondering exactly where the dip stick takes it's measurement from since the level on mine doesn't seem to move when I know it leaks out the rear main?

            Is it dipping into the pan beside the dipper tray, or is it dipping into the dipper tray itself?

            Also, anyone have a picture other than the side view in the owners manual?
