Valves adjusted- drove until engine was warm, pulled into the driveway, adjusted with the motor hot but off, checked again hot and idling. Found a few that were very loose, but even after adjustment the engine still seems noisy. Re-checked again today, cold, adding 0.002 to my clearances. Tightened the valve lash on maybe 3-4 valves, started it up. Seemed a little quieter, but also not quiet enough. A few of the valves seemed to be clicking more than the others, when I put my stethoscope to the collar next to the lifter. Clearances were fine though. Are hardened seats noisier? The three clicking valves are all exhaust.

I put the valve covers on, drove it around, and went to the gas station. It seemed to be quieter, but still not quiet enough. I was going to recheck hot and idling but it was 90 degrees, so I'll find a cooler day.

Next on the list is more horn troubleshooting. A closer inspection of the wire from the relay to the horns indicates it is original. Also, the relay is designed to have three screws, but is only held down with two. What are the odds it is incorrect for the car? Seems odd that Packard would only droll two holes in the mount if the relay had provisions for three. I tested the relay, and it works fine. I did clean up the points a little with a file, and reset the gap.

Also- the insulators where the neck of the horn sits in the mount are just chunks of heater hose. Looks like crap. What was originally there? Maybe just a rubber grommet?

Good to be driving it. Still grinning with how much better it rides with two good shocks and new king pins!
