Starting to see some circle track engines with a line that runs out of the back of the head, and down to the oil pan. I assume it is acting as a vent of some sort, due to windage off of the crank. Also, only seeing this on the passenger side. Was told from some hotrod/gearheads, that this line has been used by drag racers for awhile, especially with big stroked big blocks.
What size line are guys running for this? Pros & cons of running this line?
Thanks.
