3. Jence I changed to straight breather. It did catch lot of oil though.

4. So how would head breather sucking air off boost?

Maybe evos has more crank case pressure. I never done the test on tee joint two breathers together. It was a concern that one of them would block the other.

Pcv should be blocked, its after throttle, even if ur tmic is dry. There still be oil being sucked into manifold. Mine had a small puddle when I took the tb off.
