WOW.. So I had cleaned and checked my PCV valve before and assumed if it rattled when I shook it, it was good. Did the balloon test and it was leaking air. Bought a new one and surre enough, no air leaked with the balloon. AMAZING TEST.
@@ajayprakash1798 Yes I did. However the rough idle came back and I just checked my Solenoids on the side of the engine and one was sticking, so I have new ones coming today. But if the PCV valve does what mine did, it is bad and replace it. Did you test your PCV? Mine was $22 at O'Releys.
I just removed my pcv valve and noticed oil on the hose end. It had a very light rattle. So immediately I wanted to try the balloon test. The balloon inflated on both sides of the valve and the air also leaked. Thanks for this video.....I never knew about the balloon test...only the rattle test.
I know Im asking randomly but does someone know a way to log back into an instagram account..? I stupidly forgot my account password. I love any tricks you can offer me!
@Orlando Zyaire I really appreciate your reply. I got to the site on google and I'm trying it out atm. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
Some models of PCV's are designed to NOT fully close, so even a new OEM PCV will pass a bit of air. The balloon test is only valid for certain models, that are supposed to fully close. The only way to tell which type you have is to buy an OEM PCV, and do this balloon test on it, then compare with your old one.
this way the test may be inaccurate. The suction pipe is connected to the place where you attach the balloon. Oil vapor comes from the large part. I think it should normally be closed on both sides, and when the pressure increases, the valve should be opened with the help of the suction. In this way, the valve always remains open and oil vapor constantly flows to the suction.
Only thing I do different is to half way fill up the valve with gumout and THEN holding both ends closed I shake the heck out of it and repeat until the valve sounds nice and loose and the cleaner is coming out clear. Once dry I blow through the outlet end to see if it is sealing ok. Good enough for me.
Any tips on installing it? I have a 2014 Mini Cooper S. Should I simply intercept the connection of this hose to the PCV, or should I replace this hose with a new silicone hose from the PCV, new catch can, and new silicone hose to the intake? The existing hose looks like it might be too firm to place much of anything in between
I checked the PCV valve using balloon test as well. I inflated as you did and then leave it for a couple of minutes. As minutes goes by, the ballon deflated very slowly. In fact I heard a hissing sound on the PCV valve when deflating So my question is a good PCV valve should be totally air tight sealed or not? Thanks
try to clean the pcv valve first, but if it still leaking maybe you need to change a new one..pcv will close on engine shutdown and if there is a backfire..thanks for watching
I cleaned it throughly using carb cleaner but there's still hissing sound in the PCV valve. Though the balloon air takes totally deflated in 4 minutes. I replaced my Camry genuine parts PCV valve 2.5 year ago. I travel roughy 6k miles yearly. My question is PVC valve should be air tight sealed when testing a balllon or it just prefectly normal a hissing sound can be heard. Would appreciate other members can share their views as well Thanks

Not all pcv-s are one-way. The easiest way to check, with pcv out, is to block intake side and apply vacuum (a syringe or something) on the cover side. This should close the valve, while valve closed and vacuum still applied remove the intake side block and the valve should remain closed, no movement - good valve. Clean it if not done yet and reinstall. P.S. if you're gonna use the finger and mouth method be sure to clean that valve extremely good because if the valve is bad then you can guess what happens with all that gunk from inside it ( and even if it isn't bad).
I suggest people NOT check it by using your mouth if the tube is still connected to the valve cover. I just came back from the physicians office because I did just that and inhaled a lot of crankcase fumes. I ended up with sores all over my hand and body that developed the day after and debilitated me for a week because I had some reaction to it. I literally looked like a leper. The stupid part is that I actually have a hand vacuum to test these things but was lazy to pull it out.

From what I understand, the whole valve cover needs to be replaced if you want to replace the PCV in that case. What I'm not clear on is how you can test the built-in PCV before going that far
Hi can you help me the crankcase breather valve on my skoda fabia i combi 6y5 1.4 mpi only allows air one way, at idle the engine pulls air through the PCV valve inside the crankcase is that normal? shouldnt it be the other way around? i tried blowing air through the breather valve and it only goes one way towards inside the crankcase which means it can never push out the gases throught the valve. Is this normal? i cant find any information, only found one guy saying something about one way pcv valve, but why is that one way towards the crankcase it should let air go towards intake :( what do i do?
The breather hose is connected from the intake pipe where the fresh air come from, then it pass thru the crank case, and from the crank case unburned gases exit to the pcv due to the vacuum. And the pcv hose is connected to the intake manifold where unburned gases is injected. I think its normal .
@@jlsetnuper you are right my car system has a differentl setup, it pulls air through that little ventilation valve into engine then exista on the backside of the engine into the crankcase ventilation sistem that contains a difderent pcv valve elwcteonically controlled and from there back into the intake manifold on jts lower part where i cant see it , i thought i have and old Style pcv valve thats bidirectional and its stuck one way like many youtube mechanics show on their cars.
@@jlsetnuper yanıtınız için teşekkür ederim. Bozuk Pcv valfi gaz kelebeği adaptasyonu nu etkiler mi? Veya egzoz gazı düzensizliğine neden olur mu? Çünkü motor bazen çok yumuşak ve sessiz çalışıyor, bazen ise gürültülü ve titrek çalışıyor.
@@jlsetnuper wrong If the PCV valve is stuck open, oil will be siphoned from the crankcase under high vacuum conditions and cause engine to burn it and causes tons of blue smoke out the tail end, look at your filler, cap if their condensation on it along with milky stuff you have a bad pcv valve.
@@chuckychuck pcv valve is always open when the engine is running..it will only close when there is a back fire or the engine is off..check the video while engine is running..

A oil catch can or air oil separator will catch the oil vapor and send cleaner air back into the engine and it will run better that’s what I did
