How can you tell when a PCV valve needs to be replaced?
PCV Valve Replacement If the valve doesn’t open and close on schedule, or if any part of the system clogs, the result can be a rough idle, sluggish acceleration or increased oil consumption. Rough idling is commonly caused by bad spark plugs, so problems with the PCV valve are often misdiagnosed.
Will a bad PCV valve throw a code?
The PCV won’t throw that code. Check the filler neck and fuel vapor pressure sensor. Question: What kind of damage can result from a bad PCV valve? Answer: You’ll see sludge buildup that will slowly destroy internal engine components, and oil leaks from damaged seals.
How long does a PCV valve last?
