Do you have a check engine light on or oil leaks happening? A bad PCV valve could be the culprit! In this video, I outline the top 7 symptoms of a failing PCV valve, so you can address this cheap fix before major issues emerge.
We'll cover:
What does the PCV valve do? A quick primer on its function
Increased oil burning and consumption
External oil leaks at seals and gaskets
Rough idle and stalling episodes
White smoke from the exhaust pipe
Oil residue collecting in air intake tubes
Sludgy oil formations in the crankcase
Check engine light trouble codes
I also discuss some simple at-home tests you can do to check PCV valve function. Things like removing the oil cap to check for vacuum suction. Plus, how to monitor engine idle for changes when pinching the vacuum line.
Replacing a bad PCV valve before it fails completely can save you money and prevent bigger headaches! I recommend being proactive once you spot symptoms emerging. And consider a preventative swap every 60-100k miles.
