Maxxforce 13 Crankcase Breather Problems đź””

The MaxxForce 13 uses a spinning "squirrel cage" separator driven by oil pressure to fling oil droplets out of the crankcase gases.

If the bearings fail or the assembly becomes clogged with sludge, the spinner slows down, losing its ability to separate oil from air. This causes the system to flood, forcing raw oil out of the breather tube—sometimes at a rate of several gallons per day. Jet Plate Erosion maxxforce 13 crankcase breather problems

Over time, the brass orifice can erode and enlarge. This reduces the velocity of the oil spray, meaning the spinner doesn't spin fast enough to separate oil. Simultaneously, the larger hole dumps more oil into the housing than the drain can handle, causing it to overflow out of the breather.
