As an engines piston rings wear, the oil control ring or rings can lose there effectiveness. More oil will stay on the cylinder wall and end up in the combustion chamber. This can also happen if a car isn't well stored and the cylinders corrode. The build up of corrosion pitting will make it difficult for the oil scrapers to do their job.

Blow by is from wear on the compression rings that allows combustion pressures to go past the rings and pressure up the crank case a bit. This will lead to oil vapor exiting the crankcase vent and is also a form of oil consumption due to all the heat that builds up in the crank case. This just vaporizes more crankcase oil.

I've heard a lot of old wives tales (mechanics tales) about model T engines. Folks tried all sorts of things to gain improvement of performance. Whether they were effective or not has yet to be seen. The water pump installations are also a point of contention. Some swear by them and some swear at them and take them back off.

The main thing is that the car is still functioning and is used regularly with proper scheduled maintenance. The 92+ to well over 100 year old cars are still around as examples of the reason that Ford was so successful back in the day. The simplicity like that just isn't known in this day and age.
