2003 Hyundai Elantra Question: crank shaft seal dislodged and leaking oil

Answer 1
Excess crankcase pressure due to a restricted PCV valve could cause this or a kinked or restricted PCV hose. if the engine crank "breath" it will develop pressure internally and cause several engine oil leaks. Could the seal just got hard and brittle due to age? -
