I showed a mechanic blackened spark plugs and he said I'd need an engine rebuild. Then I watched this video and checked the PCV valve which needed replacing - spark plugs now fine, big money saved. Thank you!

I bought a car that was blowing a light white mist through the oil dip stick when I tried to check the oil.(while the car is running/on)
Also light oil mist pushing up through the oil cap/oil refill cap when I take it off.(again while the engine is running.
I for sure though the piston ring seals/ head gasket was blown (but no white or cloudy oil in dip stick).
I bought the vehicle anyways thinking I had to change the motor.
It turned out to be just the pcv value was stuck and it was all I had to change for less than $25.
Bought the vehicle for $1000.
The vehicle is still going for $5-6k.
Man I hot lucky.

I had a crack in the PCV hose on my HK Barina that I missed for a couple months - causing an initially very subtle but increasingly rough/high idle that would eventually either stall or get stuck at around at 1.5k rpm and lose acceleration altogether until the engine was switched off and on after a 5s wait. This video was a great help.

Excellent explanation on the the purpose of the PCV! I guarantee that most mechanics wouldn't know this! Mechanics nowadays simply replace parts until the symptoms go away!

Great video, thank you, you saved me thousands of dollars of unneeded repairs that i was planning but it turned out that my pcv valve was stuck closed and this video was all the only info i needed to figure that out. Thank you

PCV Valve on my Honda cost less than 5 bucks, took me less than 5 minutes to replace. I cleaned it with carburetor cleaner offen as I can.

My 2008 Honda crv 2.4l had issues with a lean bank 1 and ran rouph at a stop and fuel mileage was horrible. I found a collapsed PCV hose and changed the hose and PCC valve. The car long and short term fuel trims went back to normal withing 10 percent of each other and fuel mileage improved with smooth idling. If Pcv valve is closed it increases crank case pressures and could cause oil leaks out of the rear crank bearings, oil pan head covers and sludge up your engine. Small part big problems. Check it and make sure it's working properly. And please don't vent to atmosphere. It's better to have engine burn it clean then to pollute air even more. I also had to clean my throttle body because the dirty air clogged everything up. I had just bought this car used and must have been like this for a while. All good now. Thx

I think best to prevent the PCV Valve from getting clogged up . Is to have routine oil changes every 5-6000 miles with a new filter . And to use a detergent based engine flush such as AmsOil or Liqui-Moly each time .

Well informative video. I know too much about PCV but your video added even more information to me.

[maccaten]

Great video!! Unfortunately found it one day too late :( Every sensor replaced and the problem persisted. Didn't even know a pcv valve existed! Brilliant explanation though. Will certainly know for next time.

[pattywoo]

Great video - very helpful to a complete novice!

[tgvoaden]

The best video I have seen re the PCV, ,well done and thanks. on my way to see my local auto electrician, I think the valve is in the rocker box so expensive.

[dimicharitidis]

I had anti-freeze constantly bubbling up and getting all over my cylinder covers in my Crosstrek. I've taken it to a mechanic, and they told me that the PCV valve was busted and had sucked oil into everything, and the oil had caused a lot of tubing to crack and break. Estimated cost of repairs would be ~$1000 (all while saying there's no guarantee it would fix the issue). They also told me this could have been caused by an oil pan leak (Subaru gonna Subaru), and they gave me the estimate of $6000 to fix that.

I'm thinking on just having the PCV valve and tubing replaced because that seems to be the most likely candidate of what caused the issue (and on a vehicle w/ 127K miles on it, I don't think the PCV valve had ever been changed). And if the oil pan is leaking, it must be a small leak, because I don't see oil on the ground, so it can leak a little while longer for as much as I care.
