Ok...this is getting really general now...it's more out of curiosity over anything else. I'd like to know why the Dodge WC manuals say the gap needs to be set with a warm engine (they recommend doing it with engine running) and the jeep engine can be done cold. They are basically the same engines, just 2 more Pistons and the componets are on opposite sides.
Anyone know the technicalities behind this practice?

I'm not sure how you would set the valves with the engine running anyways...
As far as warm vs cold, the valve clearences would be less when the engine is warm and thermally normalized due to expansion...hmmmm...hopefully, someone more knowledgeable than me will chime in. If not, I'll call my old grizzled tractor mechanic buddy, he rebuilt quite a few Dodge WCs for local volunteer fire departments through the years, he might remember. (Hes owned a well bubbafied GPW for about 40 years, lol!)

Yes the "Professor" is correct, the stem of the valve may grow longer as the engine heats to normal operating temp, if set cold you may run the risk of a burnt valve.  |

Interesting and it makes sense. But why wouldn't that practice be addressed in the jeep manuals. or is it and I have just not noticed it all these years?

Some engines are set cold, some hot, and I have seen in manuals hot and cold settings. |
