So I disconnected the pcv hose and blocked off the vacuum hose connected to the manifold. That eliminated the white smoke issue. I noticed that there was oil in the vacuum hose getting sucked to the manifold. Not entirely sure what this all means. I drove the car for several years with out the pcv being connected to the manifold vacuum. While in Afghanistan, my dad had taken the car to get tuned at a local guys shop where he then decided that there needed to be a pcv to manifold vacuum established. Question is....am I hurting the car blocking off the vacuum line and not having the pcv connected?

It's my understanding that the pcv will get toxic gasses out of the crank case.
What kind of valley pan are you running. The tomahawks supposedly dont suck oil like some others.
