My main oil line is leaking where the pressure hose meets the hard line.. Its metal on metal so how about a J-B weld job???

Would that work????

 

That would be a no. The oil lines are only steel braiding overtop rubber hose. Once the hose is broken open its time for new hose as there is no hope for a 'j-b weld' job, since the oil will still permeat out from another spot in the line.

 

Replace the line. The local hydraulic shop can make you a new line very cheaply using your old fittings. JB Weld won't work.
