No. The front elbow is just a connector to receive filtered air that is drawn into the engine from the air filter. On the inline 6-cyl, the CCV is toward the rear and is the smaller tube running to the intake manifold. It is precisely sized to meter the amount of vapor it draws while running.

Installing a PCV in the front tube will overpressurize the engine, causing it to blow the gaskets and seals, creating a series of repairs that never solve the problem.
