In some older vehicles before the pcv system they used a tube that released the oil and gases directly into the atmosphere. this was before pollution was a big problem. besides the heavy pollution that caused it also covered the bottom of the vehicle with oil and the road if it was a wore out engine with lots of blow-by just something i learned thought i would share
