As for pluging the hose, bad idea unless you dont mind blowing seals like the ones on your valve cover. That PCV valve is there to vent and if its getting clogged its from blow-by.
First of all WHAT OIL SEALS ON THE PISTON ??? Second excessive blow-by is not caused from bad oil rings. Third the hose that gets plugged goes to the intake not the valve cover. You put a breather on the valve cover. Forth it is not getting clogged it is sticking open so when there is vacuum it is sucking oil.
I am willing to bet that most of the problems stem from lack of oil not broken down oil. For example, my low oil light came on ,so I added oil now my engine is making a noise.
I have seen motors with so much fuel in the oil that it has the consistency of fuel not oil. The motors are still running with no spun bearings.
I have seen my motor suck down 2 qts of oil in less than 500 miles. Once the problem of the sticking pcv valve was fixed it would use approx 1/2 of a quart of oil in 3000 miles.
The biggest cause for spun bearings would have to be lack of oil.Metal on metal is a bad thing. shawn
