I probably already know the answer...

In the winter I volunteer taking hospital employees in to work when the snow is bad. I have had some tsrting issues that seem to be more apparent when it is raining. not sure about cold. I need this 91 XJ to be usable at a moments notice. If the cooling system was in tip top shape, In what conditions could the 4.L run for more than 24hrs? fresh oil, freezing temps, a more efficient fan..... what are your thoughts?

If everything was in good shape it should run fine until the oil needed changing. There is a team that run a 4.0 Cherokee in the 24 Hours of Lemons race and they keep it on the redline for pretty much the entire race, and take high speed corners which starve the engine of oil at times. All of this being done with a typical 4.0 and they do pretty good for their class.
