That does make sense. 2LTE's seem to have a lot of crank-case air movement for some reason; not sure why. I don't think it's an indication of wear, as I've heard about it lots in my reading forums. Restricting it I suppose could cause the air to find other paths (valve guides?) which would push oil. LIghter viscosity might increase the symptoms.
Rather than putting the PCV hose back to the intake, you should consider just running a hose under your truck. This is how a lot of the older diesels worked (3B stink pipe). Will at least prevent the sludge from going into your intake. I ran a oil catch can for a bit and had some problems with it, so now just run a stink pipe.
