Maybe it you give it a form where it doesn't have to divide by zero?

ContourPlot3D[
 y^2 (4 x + z) == Cos[x], {x, -5, 5}, {y, -5, 5}, {z, 0, 10}]

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
