In this video I show you how to replace a PCV (Positive Crankcase Ventilation) valve. Whether you're a beginner or an enthusiast, this video aims to provide you with all the necessary information about PCV. A working PCV is important in maintaining a healthy engine. You'll learn about the various components of the PCV system and how it works. I explain the working principle behind PCV and how it helps in removing harmful gases.
A bad or blocked PCV valve can cause issues. It can cause loss of engine oil through formation of new leaks made through weak seals and gaskets, or causing oil to get past the piston rings. If you burn oil, over time will damange the catalytic converter and O2 sensor, which both are very expensive.
On this Honda engine, the PCV is located in the front of the engine. You can see in the video there is oil residue around the positive crankcase ventilation valve. This means that that the PCV either is not working properly or the seal is an issue. Usually if the PCV isnt working as it should, it will push oil residue past the seal instead of taking it back into the intake manifold.
The signs of the working PCV is that if you shake it, you will hear it rattle. In the video I compared new and old, the older one does rattle but it is muted. It does not mean that it isnt working, but it could mean it is not working efficiently.
The PCV is connected to the breather plate or stock catch can. This separate the oil from the vapor. This system was put in place to reduce harmful gas emission into the atmosphere. It also is a mechanism to reduce crankcase pressure. The reduction of crankcase pressure was always an issue in the past. The PCV system is a simple way to reduce engine crankcase buildup / pressure and to reduce harmful emissions.
You can also clean the PCV valve. Because this is a plastic PCV valve I would clean it with a water based degreaser then spray it with a MAF cleaner. However I chose to replace the PCV valve. This is a relatively inexpensive part. You can get a bigger repair bill due to oil leakage and engine problems if the PCV valve stopped working.
As this is a plastic PCV valve it will fail eventually due to many heat/cold cycles. So it is better to replace it as a preventive measure.
A bad PCV Valve stuck open or closed can result in the below:
Oil leaks past seals and gaskets
Oil burning as pressure pushed oil past piston rings
Some from exhaust as oil burns in combustion chamber
O2 (oxygen sensor) can go bad if you burn oil
Can cause buildup of sludge in engine
Catalytic convertor can go bad if you burn oil
Poor fuel economy causing engine to run in a rich or lean condition
Rough acceleration or rough idle as air to fuel ratio is imbalanced
Check engine light may turn on as PCV valve impacts performance and emissions

Part numbers for 2009-2014 Jazz and City: 11855-P72-000: Rubber grommet 17130-PWA-003: PCV -> applicable to other small Honda vehicles (confirm before buying) 17131-RB0-000 or 17131-RB1-000: PCV Hose -> if is damaged or feels flimsy/squishy replace it as it could collapse during PCV operation resulting in flow restriction. --------------------- Honda FIT 2nd gen 2009-2014: 17130-PND-A01: PCV 94109-14000: Washer for PCV -> same 14mm washer as oil drain plug for Honda's 17131-RP3-A00: PCV hose

I have a 2010 1.3 City. I am facing this issue where under 2k rpm the car feels very heavy on each gear, but as soon as I reach 1.9k - 2k rpm, the car becomes extremely light. The PCV valve has never been changed, but there is no oil reduction. As for the mileage in my most recent tank, I got around 16.8 km/l on ODO (571 km), it is mixed Isb highway driving + within society as well, the actual figure for that tank was 14.5 km/l. However, with a light foot and very soft accelerations, over a 60+ km round trip I do get over 21 km/l on display. Sorry for the long post, just wanted to give a little background. I drive the car at 60-70 km/h and never over 70.

That is planned. But I need to wait a bit more for valves to get out of spec with milleage, so it will be a while.

is it okay sir? when i remove the pcv valve of my honda jazz, almost half of the grommet fell inside.

@TheWrenchWiz 6 ай бұрын

If the passage inside is blocked, then then its a problem. Long time back I had a small piece fall inside, caused no issues. Monitor your oil levels. If you see excessive consumption or maybe a leak start somewhere, it could indicate the passage is blocked. That breather plate isnt complex to remove, held on with some bolts and sealed with gasket maker. Getting to it would be more time consuming.

Hi may pcv valve got broke the other pieces is inside na pvc room is there a problem if I can install a new pcv valve without getting the other pieces inside ?

@TheWrenchWiz 3 ай бұрын

If it has blocked the passage inside then yes it can be a problem. I don't think a small few pieces will block it, maybe restrict the air flow, depends. I also dropped a small piece inside on a previous occasion. Have had zero issues.

where are you located?

From Philippines sir😬 any link for online shops (example shopee) sir will be much appreciated 🙏🙏

@TheWrenchWiz 5 ай бұрын

@@user-pq9lb8ml1m I would would not know any online shop for your location. The best option to ensure if you want a genuine part is to go to Honda, tell them you want this part 30530-RB0-004 (double check if its the knock sensor you need). They may not have it in stock but they can always order it in. For online shops ask them and check any feedback if they indeed sell genuine parts.

@user-zb3lw5jt8o 4 ай бұрын

Hi sir, what happens if most of the grommet fall inside? I've tried to took it off but most of the grommet fell inside and i couldn't get it out

@TheWrenchWiz 4 ай бұрын

The issue is if it has blocked the passage inside. Try getting a wire of some sort to see if you can fish it out. Else just install new one and monitor your oil levels. If you notice increased oil consumption after then you have open it up, the breather plate, and get it out.

The PCV valve on my 2009 Honda Fit does not look like this one. It is the same metal one that is on the Honda K-series engines. What year is the one in this video?

@TheWrenchWiz 28 күн бұрын

I mention this at 4:43. Yes your right its a metal one, way easier to remove and no rubber part to deal with. The one shown in the video is for a 2010 Jazz/City.

Is it possible to clean it with a spray? Instead of buying one.

@TheWrenchWiz 4 ай бұрын

It should be to some extent. I would use an electric contact cleaner or MAF cleaner, as it does not leave any residue behind. However, if the PCV valve is plastic made, it will eventually fail. The plastic will become brittle and stop functioning. So this is why I recommend replacement.

@VicManBRA 4 ай бұрын

@@TheWrenchWiz thanks for the reply. I took mine off with the help of a mechanic. Its metal made . However its allowing air past both directions. And even cleaning it with spray didnt help. We ask honda dealer a new one but its only going to be available in 7 days. May that be the reason why my oil is getting burned? It never did. Now it disappear half quarter every 4/5 k km. Thanks in advance

@TheWrenchWiz 4 ай бұрын

Yes a faulty PCV valve can cause oil loss/burn. Inspect the hose that goes from the PCV valve to the intake manifold, if its oily have it cleaned.

How did you knew that your PCV valve is faulty?

@TheWrenchWiz 9 ай бұрын

The old PCV valve still does rattle but is it at 100% functionality? I cant say. But the oil residue I showed in the video (around the PCV seal) is an indicator that something isn’t right. This is a plastic PCV and it will eventually fail. By fail I mean it will also lose structual integrity, being exposed to many heat cycles. This time it took around 10 minutes to get everything out. I took it out once after it had 100% failed. It took hours as it broke into pieces and all effort was to make sure pieces didnt fall inside the oil seperator. I also had more oil loss between oil changes. So I now change it as a preventive measure, rather than wait for it to completely fail.

@musabkhurshid8530 9 ай бұрын

How does one knows that PCV value is not functioning?

@TheWrenchWiz 9 ай бұрын

If it doesnt rattle when you shake it, its gone. But again, just because it rattles does not mean its 100% perfect. You can test the airflow too. It should only go in one direction, if you can blow air both ways, its gone.

@musabkhurshid8530 9 ай бұрын

how will the car behave if the valve is faulty?@@TheWrenchWiz

@TheWrenchWiz 9 ай бұрын

You can get more oil consumption. You can start burning oil, oil can go past seals. Engine could idle rough, have overall poorer engine performance and milleage could suffer.
