Is my PCV valve causing oil consumption? | Oil BurningExperiments | Episode 7

On newer cars I don't know when they started the pcv valve doesn't give the oil burning (sucking) problems that it used to

Can you test if the valve is good are bad?

Probably the most cost affective thing for reducing oil consumption is the high mileage oil.
I'd bet you would be near 700 miles per quart.
As that's what I have found in the autos I've swiched to it.

Put a catch can on there

Means: new pcv valve can't stop oil burning 😭

Wow, for $9 that was an awesome elimination video!!!! Thanks.

I already changed the PCV valve on my car. But still bruning.

Can’t go wrong with oem

A quart of oil for going only 370 miles, that is a big problem. you need a fifty gallon drum of oil hooked up to a pic line to feed the engine with oil.

Im surprised you have not ran compression tests on this. Compression and leak down would tell the exact issues

Pour petrol over the car , light it up and smile. Then go and buy a decent American car instead of Japanese rubbish.

VW/Audi has an Oil/Air Separator that works in conjunction with the PCV valve. If the PCV valve is stuck closed then the extra pressure in the crankcase pushes oil up the Oil Separator and througj the intake manifold causing white blue smoke at the tailpipe....this is often overlooked and mistakenly diagnosed for bad valvestem seals or piston ring blowby. To rule out piston rings do compression test first. PCV valve is very cheap so before tearing down the head for a valve stem seal replacement first do the PCV valve and clean the oil air separator as well as all the ventilation pipes on the engin.... in turbo charged cars a seized or malfunctioning turbo can also cause oil consumption and white smoke

Let me know it's not going to cost that much because I won't go to a dealership to purchase

the antifreeze does not circulate completely through the engine, the oil evaporates

have you lost the engine cover ? or do you prefer to leave it off ???

i'm jealous of people having their pcv valve exposed like this

If you clean it or replace it, will the oil leaks stop (if that is the issue).

Hi Dave. First, big thanks for sharing with us your knowledge and experiences, it is awesome. I Have a question please about my PCV on my CLS 63S. WHen i 'm pusing the gaz in neutral gear position to 4000trm it takes a lot of time to go down back at 1000trm. The engine idle looks perfect, there is no self variation up and down. No oil consumption too. So do you thing the PCV valve could be the reason why please ?

I live in Kitchener Ontario Canada. The exact same part just cost me $46 …..why is that?

that wasNt a ‘smige’ it was 1.53247 smidges.☹️ NEhU, wat happens if oil is leaking from crank case through pcv valve?, would 1 drop block the vapors, or the vapors drive past it?-🤔

Get the correct tools

Toyotas burn oil. Always have, always will.

Just a check valve

What's the old one bad ?

What happened with the real thin Pennzoil the 0 30 did that help at all ?

A red coffin on wheels, when you have an accident they just bury you in the car😢 I don't care what the crash ratings are in that thing

No I'm done I'll check back with you in a year or so

Compression and/or leak down test....

just did mine on my 07 avalon . seems to have helped.

On my 2010 civic, if was a pain.

Just randomly stumbled upon your video. If it leaks like a lot after doing every possible thing other then an engine overhaul. I would just drive it as is and just keep topping it off. No more oils changes but get a high mileage filter and change that only.

I am finding this approach helpful, My issue is which in a series of small repairs do you do first?, it all needs cleaned up from the oil literally being blown everywhere (multiple little things went on the same ride), the thermostat, the pcv, cracked injector, the fan, and everything that got messy and gunked from the oil. I'm sure there's more issues yet to find but I can't determine what. Tips please, please (it's older car I love and live way out in the woods, I gotta do what I can) it's about 6 more mos till I can get another car (and pass this one to one of the kids)

If you have a 07 to 13 Chevy Silverado the pcv is built into the valve cover. Go ahead and replace both valve covers while you're at it. This will fix your oil consumption problem.

That looks like a lot of oil usage, does it look like a two-stroke when being followed ???? Next step 20-50 oil???

158k miles 2l soul running very strong with replaced spark plugs, coils and pcv valve, no more oil consumption, purchased part from amazon for $13, same with my kids sportage 2.4l

Not working for me. Oil still keep burning.

dealerships barely keep parts for vehicles older 4 years

ther3s no way that pcv valve was brand new.... it looks all pealed away the paint

Did you have a crow's foot in your hand? To use like a wrench? Instead of a wrench? Shame!

... cette voiture consomme autant d'huile que le McDonald's de mon quartier !😂

They didn't have the PCV valve for my Camry at the Toyota dealership either. It seems odd-common tune-up item. How many different PCV valves go in Toyotas, like about 4?

<3

You are lucky you don't have a Ford vehicle.

Nice work

Many moons ago, the blowby or crankcase fumes were vented to the atmosphere via a rubber tube running from the crankcase to the atmosphere. Along comes the EPA that said that was a no-no. Alas, the PCV valve was born, which directs the blowby gases back into the engine to be burned.

I change my pcv valve every year, along with my air/fuel filters; super cheap insurance🤷🏽‍♂️

Why not using LUBEGUARD oil seal with every oil change

So I just changed mine this morning and my oil light was on and needle jumping from high to low wildly. I changed the oil and guess what? About 1 quart in my truck smh. I changed the oil and put 5 q in it. The light went off and the truck stopped ticking so let's hope for the best.
