Q: Can I drive without a Pcv valve
I just want to know if I can drive a couple of miles without pcv valve
My car has an automatic transmission.
Your engine will not run good and my stall at idle with no PCV system or valve working as it should. If you need to drive a couple miles to get the parts needed then plug the vacuum side of PCV line and it may be okay to drive a short distance since running longer than this may cause the pressure to build up in the crankcase and cause oil leaks and engine will run lean or rich without a properly functioning PCV system.
