Hans,

I agree, setting the valves on a Packard with the engine running is one of the least favorable jobs to do; especially for the center cylinders which requires working around the exhaust manifold.

Others here have adjusted the valves cold and add about .002" to allow for stem growth when warmed. They can comment on their method and the extra clearance.

I prefer to set them at operating temperature, but with the engine not running. After doing all the prep work for a valve adjustment (RF tire removed, fender splash shield off, and tappet covers removed) I thoroughly warm up the engine then shut it off and set the valves for No. 1 cylinder; then, restart the engine let it run for a minute or so and set the valves for No. 2 cylinder; and repeat this procedure for the rest of the cylinders. This will maintain operating temperature with the benefit of the engine not running.

There is a method for setting all the valves with just two revolutions of the engine. I don't have this procedure memorized, but others may know it or where it can be found.

Once adjusted, the valves will not need this job done again for many miles.
