Q: Can a faulty Pcv valve cause catalytic converter problem

asked by on

Using excessive oil . It is not leaking. Car has no power to accelerate or climb Hills.

My car has 64000 miles.
My car has an automatic transmission.

As you may know, a faulty or clogged PCV valve may cause the engine to consume oil due to a lack pressure relief. This may eventually cause problems with the catalytic converter as well due to the car’s inability to expel the exhaust gases properly. i would suggest having a professional from YourMechanic come to your location to diagnose and inspect your PCV valve problem.
