if a pcv valve had failed would it cause blue smoke all the time or just certain conditions, like idle or only when there is a vacuum etc

owen

In fact it would cause that much smoke you wont see behind you lol

Most of the times if the pcv isnt sealing, boost escape to crankcase and force the oil throu the rings to the chambers where it burns and gives smoking issues.
