There is two lines from the oil tank, one goes to the pump, you'd think from the pump there would be a line out to the intake, but there isn't. The other line from the tank goes to the intake. Does it somehow build up pressure in the tank to force oil out the tube that goes to the intake? Should the oil tank cap be vented or no?
