Graphics3D of implicit equation

GROUPS:
hi all, above helped me solve a solid of revolution, but now I have to do the solid of intersection of the following graphs
ContourPlot[{y^2 - 2 y == x, y == x}, {x, -1, 3}, {y, -1, 3}]
the problem is that I have not yet a clear idea of ​​how to make this work,I have tried to convert it to its polar form as follows,
y^2 - 2 y == x /. {x -> r Cos[\[Theta]] , y -> r*Sin[\[Theta]]}
Solve[%, r]
mpediment remains the 3d intersection graph of functions, any solution to this is welcome

my rotation axis is X, later to calculate the volume, the fact is that I need the 3D graphic of the above graphs. My idea is to represent its parametric form and then use the graph to see parametricplot3D three d, I hope someone knows some other method to make the solid of revolution, still waiting for some comments

Hi everybody,  finally I could solve my problem, here I show that 3D graphic rotated 270 degrees about the x axis

graphs used are as follows,graphs used are as follows, to subsequently rotate about the x axis
