Some of my vehicles had responded very well over the years to doing seasonal valve adjustments. Valve lash does very enough with the ambient air temp. at the time of adjustment to warrant it but be careful. I am looking at your geographic locations. One in Michigan and Oklahoma. The extreme seasonal temp. changes in Michigan can cause havic with diesel valve clearance.
Pick a day with moderate temps for that season to get the best adjustment.
I adjusted valves on one of my gasoline vehicles one cold winter day (why? I don't know!) and nearly fried my valves. A cold adjustment at 20degs.F is alot different than one at 80deg. F. Of course I am doing this in a driveway or unheated garage.....
