  To replace the rear seal should I loosen all the mains to get slack and then push a new half in over the crank? Or is there a one-piece seal? If so is it better and worth the extra trouble to install?

  hi 1950 Ford v8 rear main seal
are you sure it is the rear main seal and not something else, check the engine over carefully. oil pressure gauge, back of intake manifold seeping, fuel pump stand etc,,,
how much oil is leaking ?
is the engine rebuilt ?
are the oil breathers clean and working,?
any blow by in engine, internal pressure will make the oil run out of the rear main,? easiest exit
you will need a rear main bearing seal installation and removal tool, if you want to do the job,
if you loosen the main bearing caps, you still have the transmission input shaft holding the crank in up position,
do you intend in removing the engine and installing new main bearing ? mic the crank,

what I would do is use plastic gauge on the rear main bearing, first to see what you have for play in the crank and check the book for what they give you for specs on play,, then go on from there,
and see what condition the seal is in, it is a rope seal and might be hard and brittle ?
let hear how you made out, my 2 cents 37Ragtopman

  Thank you Ragtopman, that is a lot of good information.
The seller told me it was a fairly recent overhaul, and the amount of oil is not that great. But a little bit goes a long way on my garage floor.

I am working on another problem now. My overdrive will not engage. I have checked the solenoid on the bench and it works fine, but when it is intalled it won't engage. The relay also works fine. I feel sure the solenoid is installed correctly because it has to be rotated about a quarter turn to install or remove. When voltage is applied with a hot wire, it sparks but nothing happens.

Any suggestions?

  Here is a link to overdrive trouble shooting. Just change the references of voltage from 12 volts to 6 volts.
