Problem with ContourPlot3D

Hi. I'm unable to obtain a clean plot of this DE solution: ContourPlot3D[y^2 == Cos[x]/(4*x + z), {x, -5, 5}, {y, -5, 5}, {z, 0, 10}] If I specify PlotPoints->50, Mathematica crashes. If I try MaxRecursion->4, it also locks up. The command above does produce a plot but it's jagged and has an "extraneous sheet" between the two sections of the plot. Any way to get a nicer plot? Thanks, Dominic
