Something else that I ran into on a couple of the hard oil lines was that the fittings that attached to the engine seemed to have been locked up. I was always under the impression that the intended design allowed you to spin the fastener while keeping the hard line stationary. two different fittings were locked up to the point where I had to detach the opposing end of the line and then spin the entire piece to remove it from the engine. Is there something I can soak these in before re-installing so that they work as intended?
