I'm trying to separate the oil line that runs underneath the rear of the engine and up on the right side, as the photo shows. I have tried a lot of force, breaker bar and heat, and nothing has worked. Just wondering if I'm twisting the right way. I'm holding the nut on the hard line and twisting the larger one on the soft line counterclockwise when looking from front of the car towards the back. That should be correct, right?
