Worn or aligned rings will give an increase in crankcase pressure and this can shove oil out the breather and down the inlet valve guides if they are worn too.
A wives tale still believed by some, but proven by none...and which melts in the face of common sense. Most certainly a crankcase can be pressurized by blowby, but not by gap alignment in the rings. Staggering the ring gaps is superstition.
Gas is fluid, and does not need gaps in a straight line to pressurize the case. There is no increase in case pressure to be found by aligning the gaps in a ring than staggering them. The gas need not travel in a straight line, and gap alignment makes zero difference in the pressure which may leak past the rings. None.
