did you do the oil cap dance test? loosen the cap dont remove it and see how much it dances... lil movement is good, some flopping around is marginal, if you have to have your hand above it so it doesnt fly away thats not good
another easy test is wait til it gets to about 30F outside and see if you can start it without a block heater, keep going to lower temps to see how low you can start it in, i think 20F without a block heater is good.. actually. i dont know if this test is for blowby.. but i would be assured if i could start my car in 20F |

For what its worth, I performed the cap test on my 240 with marginal results. The cap danced vigorously. I guess my engine is worn out although it doesn't burn much oil and it always started on the first glow at 15F last winter. Maybe I should be looking for a new engine.

same here, i dont have any smoke on start up that i can see, and the engine in the winter, except when my glowplug relay was out and i was using the block heater, when i fixed the GPRELAY, it started first try everytime, but last winter in illinois was mild.
my engine also burns no oil, the only time i have seen it burn oil is when i was doing 75-85 on the expressway trying to get to work, i noticed a slight drop in oil, but other than that, i dont see it burning oil

If it starts fine, especially when cold I wouldn't worry about it.

Put the oil cap back on and ignore it. Unless you are going to rebuild the engine there is no point and looking into it further. If it runs and starts fine thats what matters.
