Sounds to me like a bad intake manifold gasket.

Or its head related ie a warped/cracked head or a blown headgasket.

That causes excessive white smoke.

Pcv valve wont cause white smoke

i think its the heads then or the intake could be cracked on it, but unlikely.

A cylinder compression test will tell you if its head related.
