I have been about to pull my hair out with my 64 rear main seal leaking. I have had it replaced twice and to no avail it still is dripping. I have had to engine rebuilt twice and I have to believe that all parts were replaced when rebuilt but not totatlly 100% sure. My mechanic says that it could be the thrust bearing could possibly be bad cause he did say there was more than usual movement in the crank that he was use to seeing...could he be possibly right about that? I just don't want to go to that expense unless I am sure it will resolve it. I no you can make no guarantees, but with your experience with these year models, you might have some inside info that I am not aware of...

A special tool is described in the shop manual. It guides the upper rear main seal into place so the sealing surface does not get shaved off. Don't use it, and a leak is about guaranteed, as you know. 

I don't see the crank moving back and forth as an issue, as the surface is the same.

James 

We just did a thread on the rear main seal leaking and Kim is in the process of putting the bottom of his engine black together after he replaced the rear main seal to see the results 

Many have different degrees of a problem with the rear seal leaking in our year cars 

It SB good reading just to learn more about the subject 

The info is on the current Dashboard page 

Enjoy

Dash removal

Posted by Jake Mickley on October 9, 2019 at 12:06am 9 Comments

Hello everyone,

On a 63 CDV, if a guy wanted to remove the entire dash to get all the metal painted, and do some other things behind there, how would he go about doing that?  I checked here and the shop manual, but can't find a complete guide.

As always, and help or direction is appreciated.  Thanks!

Thanks for letting me join the club.  Picked up this ‘64 Coupe Deville a few months ago out of Beverly MA, the car has few stickers on it from various Cadillac clubs, didn’t know if anyone might recognize it from it’s “Glory days.” Everything seems pretty healthy except for the body and some very Mickey Mouse repairs, was wondering if anyone had any leads on…
