Yes, there is a way.

Take the new oil line (the upper line) and tape the end with duct tape. Then thread it between the mount and the engine from the front toward the rear. There will be a point where it won't want to go........but.......just force it.........the duct tape will protect the end of the line.

It's a PITA.........I really can't say if it's easier than removing the bolt for the mount and lifting the engine........most folks go this alternate way.
