Am I right in thinking the car should stall if I squeeze the pipe connecting to the PCV? I tried this but it just idled slightly lower for a second then went back to normal.
I think you mean isv!! It should die if you completly block the air in the pipe but not necessarily faulty unless you have a problem with your idle. What car?
the pcv on an abf can die (mine did) i cant think of any logical reason why squeezing it would stall the engine. itll block the breather and the dip stick ill pop up lol
