Help-Slushy Antifreeze

I wonder why a dry start in the winter is different than a dry start in the summer.

Not sure what you mean about dry start in one or the other. But if you have a pan heater and the oil boils there is for sure more heat directly above the element and IF it is possible to make the oil run away from that bearing by so much heat in that one spot, then that spot will not have oil for a few cranks of engine. I am not sure if the heater could make it less oily than when you shut off a hot engine and it sits there hot and runs away. In summer the pump will have oil there fast compared to in winter when oil is thick, that much I know. I have started some vehicles and it takes a bit before the oil pressure comes up when not having been plugged in. Not sure why the magnetic pan heater seems to cause engine crank damage, but as many mechanics that I have heard say they could see on the crank or bearings where the metal had a different color. having said that the bearing going out there would do the same. . Personally I know you can boil oil in one spot and not have it boil in a pan 6-7 inches away. It is hot but does not boil. I made a fish fryer that was long rectangle and had one burner in the middle. could not fry the fish on the ends of a 2 ft pan. had to put in 2 burners.

I have burnt the paint off the pan so that tells me it is getting very hot in that spot. I quit using it for more than a few hours for that reason. so far no spun bearings. I would love to have temp sensors and cameras in a pan above the oil and against the crank to see what really is happening in there when those pan heaters are being used.

Before glycol alcohol was used as antifreeze therefore "alky".
Problem ally would "boil" off and leave water which would freeze.

I have training in thermography, which is essentially the use of infrared cameras to monitor or test many things. The application I used it most for was to monitor equipment in a refinery. This could range piping that was near the outside ambient temperature to tubes inside a reformer furnace that produces hydrogen that operate between 1200F to 2000F. Almost 99% of all surfaces you encounter are being affected by infrared energy even though it can’t be seen. This energy is mostly from the atmosphere aka the sun even though it is night the sun is heating the entire atmosphere of earth. Think of a police video that is using night vision you can see the humans very plainly because of their body heat. But you can also see other object more faintly like roadways, homes and fences. This is because the camera is seeing the infrared energy reflected off of them. The heater on the pan that burned the paint is passing infrared energy from it to the pan. In this case, as it is with many paints or coatings, they become an insulator or a block to the heat energy transfer. The infrared energy hits the paint surface but as with all surfaces some of the energy is reflected but the majority passed through and then reacts with the metal oil pan which is a material far more suited to absorb the heat energy and in this case pass it on to the oil. The paint in this case is being bombarded from both sides so to speak. It’s ability to transfer the energy back out of itself is very low. The molecules in the paint heat up quickly and start to lose their bound and break up or in other words burn up which from chemistry we know they simply change. The highest percentage of them become a vapor we usually call smoke. So does the metal oil pan actually get that hot, the answer is no. This is because it was able to disperse the heat energy to the metal in the oil pan around it and also transfer the energy to the oil.
