UPDATE: Replaced the intake manifold today, the PCV orifice was completely clogged. I replaced it because the gasket kit is about $30, but the whole manifold with gaskets was $60! I'm keeping the old one and will clean it up and use it to just keep swapping out the manifold every 60K mi or so. I also cleaned the throttle body, and used CRC GDI cleaner to clean the valves. Engine is purring like a kitten now.
Awesome! Can you post links to where you bought them from?
