On both sides the top oil line nut won't budge. On the passenger side the oil line and the check valve (at the bottom of the valve) are turning. On the drivers, the check valve (at mid point) is turning, not the oil line. So on that side the check valve wants to unscrew and the oil line nut is working its way up the line toward the bend in the line. I think if I continue it will destroy the line. I got a butane torch and applied heat but it doesn't seem to help.

Any ideas?
