On the metal crossover line, it gets tightened, because it's often leaky. Tightening the outer nut results in the oil tank side of the crossover line moving toward the back of the car. This results in the L shaped soft hose being kinked.
Loosen the hard line and rotate it so that it moves the oil tank side toward the front of the car. Re-bend the tab that holds it to the engine tin.
