Agreed vacu pans are for high rpm low vacuum as stated. Just mentioned to cover all bases. Not street driven engines.
If the pcv is not working properly have seen the oil work through the threads of bolt holes. Once oil enters a bolt hole with a bolt in it there is a gap between the hole thread and the bolt thread unless it has sealer on it. Hydro static tension will hold the oil in the thread gap and any pressure ever so slight will work the oil up the thread.
If the pcv is working the negative pressure will draw the oil down the thread.
This was covered in a 2nd year class in mechanical engineering.
