It could be an obstructed air cleaner. And on and on. It’s going to take patience and insight to track it down.
I'm not convinced that the PCV valve in the valve cover is the issue people say it is. The one in my valve cover is 100% dead. My engine has very little blow-by, and the breather tube is usually relatively dry. I've rigged up a catch can on mine, and in 2 weeks of driving had a single drop in the catch can. If there is significant blowby in the engine, I can imagine a very different story. The design of the PCV valve is definitely stupid. There's no reason they couldn't have made that a plug-in unit on top of the valve cover.
