I last adjusted my valves maybe 5 thousand miles ago.

I use wvo settled then filtered to 5 microns, and in the car from the tank I have a prefilter, a vormax/racor heated filter, then another prefilter before it hits the injection pump, and I check the prefilters regularly. I also purge with petrodiesel always and so the only times wvo is in the pump is while the car is running. Could this still create residues? I have found no evidence of polymerization in my crankcase oil btw.

Hot and cold same cranking no starting.

I rotated my engine to OT and I saw both of the cams were pointed up for the first cylinder, but I haven't checked anything farther.
