56 century trans question and gas tank

Discussion in 'Classic Buicks' started by 56buickcentury, Apr 10, 2013.

  1. Picked up farm fresh 56 4 door jus put new cap rotor plugs wires and coil and I used a water bottle for a gas tank and the thing started ad ran !!! Concerns now I can't find a gas tank replacement my old one is pretty funky inside, and the trans dipstick is just strate milky goop so I'm guessing ill need a new transmission. Any thoughts ?

    Here is a video for POR 15 petrol tank repair.

    I tried the POR15 kit on my old tank. It worked nicely inside by the look but I dont think I had the outside clean enough when I applied the POR15 Black paint and it has bubbled with rust underneath. I haven't had fuel in it yet so not sure how successful the repair was.
    I think having a radiator shop have a look is a good idea.

    I think Eastwood sell a similar kit

    As for the trans I would remove the pan (or drain plug), drain the fluid, add fresh, flush through cooler lines if necessary and see if it improves. If the car has been parked up the trans may need a freshen up, new seals etc. There was a thread here about nasty trans fluid, when I find it I will add the link.

    Be aware of the older Buicks with double diaphragms.
    They rupture and fill the crankcase with gasoline!!!!!!
    Never happened to me, but heard guys talk about it.

    I've got a rebuilt pump on mine from CARS old buick parts. Kanter has them , too
    You could rebuild your pump with a rebuild kit from the same suppliers


    My car has had the fuel pump replaced twice in 43 years.
    They'll start to leak around the edges a little before they fail completely.:(

    I didn't know about them filling the crankcase with gasoline. :shock:
    I hope I would smell the gasoline before it filled up my crankcase.......

    There are two types of fuel pumps for 322
    A single screw top and multi screw top.
    Both work and fit the same. I 've used both types on mine

    The Dynaflow has torque converter drains. I don't have a '56 manual, but the '55 has two drains 180 degrees apart. The idea is that one is removed, then the converter is turned 180 Degrees and the other is removed. The one on top acts as a vent to allow rapid and complete drainage. It works beautifully, but is a messy (although not difficult) job. I would completely refill the transmission with fresh fluid and see how it works. You may be OK. The Dynaflows were quite reliable; what you have may well just be condensation. I have forgotten what fluid to put in the transmission - it originally used Type A which has been obsolete for decades.
