Re: Proud New Owner of a 49 Packard Club Sedan

As you will recall, I had a compression issue on No. 3 cylinder, and resolved to remove the head. I've had bad luck with manifold bolts, and so I decided to try to do it without removing the manifold.
My son and I got the car into the shop, removed the hood and drained the radiator. We pulled off everything attached to the head or that went over it. the hardest thig was getting to the vac line that went to the vac advance. Its under the carb and hard to see. WIth all of that done, we pulled off the acorn nuts on the head studs. My plan was to inject penetrating oil into the stud-head hole interface and let it soak for 24 hours. Then I would spin the engine and hope that he compression would pop the head. If not, I had brand new putty knives, wooden wedges, screwdrivers, and an engine hoist ready.
Without my permission, my son put a putty knife where the water was coming out and tapped it gently with a hammer. I went tight to the stud. He did it again a little further down, and it want right to the stud. Hmmmm.... So we did it a few more times, with the same result. We went thru all of our putty knives, when I lifted up on one. AND THE HEAD MOVED! We had it off within a minute. So much for the engine hoist. glad I did not buy those huge C clamps!
The stuff I put into the holes was a combination of PB blaster and some stuff from the dollar store called "LUBE." That's it. Just "LUBE." Its from the orient, and I assume full of strychnine and whale oil, but it sure works.
We soaked the antifreeze out of the cylinders with paper towels, and then coated the cylinder walls with oil, and pout some in each cylinder. I got the white glob out of No. 7; it was in the oil we put in.
It appears that the head gasket was blown between 4 and 5. My engine guy says the head is warped, so it needs decking. I have a new head gasket that came with the car (yes, I thought that was odd), but have just ordered new head nuts and washers so it will be next week before I can get it all back together. What puzzles me is that I can't see anything that would cause low compression on Number 3. I still have to spin the engine to do a valve operation check. While it is down, I might as well take care of some cosmetic issues. What color is the distributor supposed to be? Engine color, black, or something else?
