Small vid about PCV
If course it will, the breather and hose to the filter is OPEN
You say that like it was a fact.
But that breather may be a sealed unit. and if it has a hose nipple on it, that is the norm. and so
The fact is that as engines age, they may produce a lotta blow-by, especially at WOT, and just a few seconds could blow that smallish line right off the air-cleaner, but if it was secured really well, then something else might blow, and the usual losers are the dipstick popping up, or the valve cover gaskets puke.......
but this one time, I had an engine that blew oil out the back somewhere and made a real mess.
Then I bought me a blow-by tester. and hyup,
Then I pulled that engine out, cuz it obviously needed rings.
