Hi there, I am Cam.This sounds like an issue with the valve cover on the drivers side. These do not use a regular PCV valve, rather its an orifice and a series of baffles under the valve cover. If its loosing oil and no external leaks, then those baffles and the orifice may be a problem. The orifice cannot be changed on its own so I suggest replacing the drivers side valve cover assembly to correct this.
