Checked PCV valve today. It seems fine. It’s not clogged. I cleaned it anyway. Hose was not clogged also. There’s vacuum with engine on. No oil in the house. Very little oil is present in the PCV valve itself.
I will need to take it out for a compression test as I don’t have the tools for that.
Thanks again.
