Spraying Oil

AJ/FormS said

At WOT the small lines cannot keep up, there is almost zero vacuum so the blow-by has to force it's way thru there, and when it hits the choke point, the pressure finds a new place to escape. Be glad it popped the dipstick and not the rear mainseal. .
Some breathers have one-way valves in them, check yours. If they blow both ways,then your engine seems to have a ring-seal problem

its spraying oil at idle per OP. there may be other issues If the lines are to the back of the carb, they are above the butterfly (timed port) so they are offering no vacuum until the carb is cracked. If they are below the line, then that is a vacuum leak waiting to happen. are your valve covers baffled under the breathers? I had a valve cover that had a baffle that was coked up beyond passing gas. It wasnt a Mopar but same principle.
