Will be following along with great interest as your Twelve returns to its former glory.

Ps - Have updated your Registry entry with the photo from the first entry in this thread.

Great to know another Twelve is being restored, good for you taking on this significant task. I well be closely following your progress with great interest. Good Luck.

The last picture shows why you can't remove the valve guide from the valley.

I made a guide puller from a HS 5/16-24 all thread rod, a couple of nuts and a socket that was just big enough to fit around the valve seat. Tightening the nuts pulls the guide out.

There is some interference in the fit, but it doesn't take much effort to get them to move. I thought about using a slide hammer, but I decided it would be better to avoid the impact and ease them out.

I forgot to show the "C" clip removal. I will go take a pic and post it.

For some reason the picture failed to post. Operator difficulty is guess.

On the left is a guide with the clip. The ends of the clip are painted white.

Sorry the picture flipped on me, The guide is on the right.

Here is the clip with a screwdriver prying it out of the groove. The one side is out, need to move to the other side and do the same.

I had a machine shop face the seats. They put the guides in. Used a quick way driver to put guides in.

And they were a bitch to pull back. I used the same. All thread had to get b 7 grade. Other was snapping.

And I had to buy a ream. Cause the new guides aren't as thick at ends as old ones. So pulling on end closed it a bit.

I used brass on the end. And the tip still closed.

When you get to the valve clusters . Mr pushbutton was repairing the valve rocker needles/ rollers.

The rocker shafts Packard used a long plug. But as far as I know you can't get them. Only the Dorman type. I think I used 2. Per end. And I might drill the end to put a pin in. I have an uneasy feeling with those Dorman plugs.


My dad's 12 engine I have on hold. Dealing with my 56.

And. Things around the house keep popping up.

My next thing on the 12 is valve clearance.. Which is critical. Whatever clearance my dad used..that engine was quiet.

Packard gives the high and low. I'll be in mark Claytons clearance.

I am pulling the engine to make sure there are no issues and to give it cosmetic overhaul, hardware paint, etc.

I used a 2 ton cherry picker with a leveler and it came out in about 15 min. I was amazed.

Another engine bay view. I had to remove the bolts and move the steering box to get clearance. Pulled it straight out the front.
