Cannot thank you enough for walking through the various components of the PCV system. This allowed me to properly diagnose and repair the PCV system. It also saved me from spending additional money on the intake manifold that wasn’t needed…yet. I did need to run the car for quite a while (at least 30 minutes) after the repair to get all of the accumulated oil in the intake manifold driven out. I was overjoyed when the last bit of blue smoke stopped and the little engine got back to normal. She purrs like a kitten and pulls right up the hills better than she has for a while.

[@AndreiDPop]

That’s so awesome to hear! Very glad that you were able to sue this information and get your car fixed. That’s been the goal behind everything I’ve done here. Saving people time, money, and frustration.

[@Amigo4evr]

I heard this today. "Vehicles nowadays can surf the web, stream videos, navigate and pinpoint a location in a map, but can't tell you why their check engine light is on." How ironic is that?

[@spelunkerd]

That's a brilliant explanation, and your website explains it even better. I find it frustrating that mechanics don't think first about how these systems work, since understanding is necessary before one has any hope of fixing things properly. Matching blowby gas flow through a PCV with the dramatically variable intake vacuum of a turbo is a huge challenge. So, I guess we shouldn't be surprised this system is much more complex than a simple captive ball and spring.

[@godseykj]

I spent countless hours trying stop the oil leak from around the valve cover. Saw your video, ordered the intake manifold and installed it. No more leaks!!! Thank you so much for taking the time to make the video. Truly helped. Now I’m searching how to remove oil stains from driveway..lol. Thanks again!!

Hands down, Andrei creates the best DIY repair tutorials for the Chevy Cruze. His step-by-step instruction guides include pics, which virtually eliminates the need to take pics as you go along (although I recommend you do anyway). And his work-around kit for the POS OEM PCV system is ingenious and affordably priced. I feel like I owe him more money for making this so simple and affordable. Thanks, Andrei.

[@AndreiDPop]

Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working. Very recently, I had a friend install my kit which meant pushing the check valve out and catching it on the other side to plug it up with my kit. Turns out his had a tear in it, and it wasn't during removal. For many people, the check valve either gets stuck closed or even caked with deposits and starts leaking. Waiting for it to fail can often cause other issues down the road due to oil consumption. If you have over 30k miles on the intake manifold, I recommend not waiting until it fails.

[@dextermorgan5799]

@@AndreiDPop Well, I have only changed the intake manifold once on my Cruze and I have 306,464 miles now. The valve cover has been changed 3 times. But sadly my turbocharger is starting to fail. Wastegate is locking up. This is the original turbo and has lasted over 300,000 miles.

@@AndreiDPop "Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working." ... - This point cannot be stressed enough. I'm from the UK & work primarily on Vauxhall, a brand of GM, using the same systems; all are terribly designed. The intake manifold PCV non-return / check valves can indeed tear or become clogged "open" with carbonised / burnt oil deposits; symptoms are mainly observable with positive manifold pressure, ie. "boost". Faults with this valve will cause consequential faults with many other components.

Hello, and thanks much for this video and the kit you've designed... i will likely be ordering one of those shortly. My girlfriend has a Cruze, and the diaphragm on the valve cover is indeed failed and leaking vacuum.... it also sometimes makes a whostling sound that sounds like a belt squeal... when you plug the vent of the diaphragm on the valce cover it immediately makes this sound. I've diagnosed this to be vacuum leaking , and sucking air in around the crank seal. I am thinking that adding your kit, as well as a new valve cover, and possibly the hose and valve by the turbo inlet, will ALL be necessary, but I also think we should be replacing the crank seal as well....she will likely keep the car, or eventually give it to one of her kids , so I want to fix it right... Any further input or suggestions would be most appreciated. Thanks again for doing us all the service of making this video, and designing a kit to provide a metter solution than OEM part replacement....

[@alvinclarke4667]

Your video talked about the other end of the PCV hose at the turbo and a check valve there. Does that one go bad and ever need replaced? Next question: If the valve cover gasket goes bad, does this create a vacuum leak and cause poor performance? My Cruze gets random lifter noise that comes and goes. I checked the valve on the valve cover, but it wasn't blowing air. I replaced the valve cover gasket because it was leaking oil. Since then, I've had no issues.

[@AndreiDPop]

Yes, the check valve on the other end of the PCV hose sometimes goes bad, and creates a vacuum leak. We find it gets stuck open more than it does get stuck closed. Yes, a bad valve cover gasket can cause a vacuum leak. Check spark plugs, as they sometimes back out. Lifters shouldn't make any noise unless you've been using low quality oil.

[@herr_kukuffs]

Dear Dre Dan, Thanks for your great videos, explanation and kits avaliable to get - it's great solution for this strange crankcase ventilation system from GM with this PCV Mushroom valve in the intake manifold at A14NET engine and similar. I wonder to know, why they don't use the same system which used at A16LET engine, where the PCV valve made externally, almost exactly how you made at your kits? It's rhetoric question ;) But what I really wonder to know and can't find relevant information concerning this issue - what if the ventilation system will only one way. I mean, if the mushroom valve hole will be plugged up in the intake manifold and only way of ventilation will be via corrugated hose to the the turbo charger. Such way will be completely identical to the default ventilation system during the boosted, loaded mode. But what will happen at the idle mode or mode with little load ? I suppose, that if it will be not enough air at the intake manifold for the stable engine operation the electronics will open the throttle valve a bit more to provide the enough air flow. Further the more air will be sucked from the turbo charger and from the corrugated hose connected to turbo inlet - so the crankcase ventilation will take place in this case as well. I am not completely confident in my thoughts concerning this crankcase ventilation as I am not specialist in it, but why double-way ventilation system needed, what is the benefit of it? Best, Igor

[@markdelgado7677]

Dre Dan, Thanks for the video! Great explanation on the system. I have an oil leak somewhere between the charge line and throttlebody. Have you heard of this before?

[@AndreiDPop]

Yes. This is typically made worse by a missing check valve in the intake manifold, but otherwise simply means the clamp isn't tight enough.

[@ripptydevibes2581]

@@AndreiDPop Am I reading this correctly? Are you implying that some oil leaking from the charge pipe is acceptable? A lose clamp? Wouldnt this be a check valve issue, resolved with a DRY charge pipe yes?

[@AndreiDPop]

@@ripptydevibes2581 If you have oil leaking form the charge pipe, you also have a boost leak there as well. Some oil will come through the PCV system, but it tends to settle in front of the throttle body and leak at that charge pipe, even if actual consumption is inconsequential. Even a healthy car will consume some oil through the PCV system, and some of that will find its way through the intercooler and up the charge pipes. Not something to worry about unless oil consumption increases significantly. A check valve issue will make it *worse* but a minor amount of oil will still go through the charge pipe on a healthy engine.

[@ripptydevibes2581]

@@AndreiDPop Agreed, thanks for the quick reply. I guess we arent as used to seeing oil at the intake on natural aspiration, but owning my 98 mitsu 2.0l running 32psi, it was nice of you to remind me that it is somewhat normal for the Chevy Cruze to have oil in its charge pipe lol. This customer is missing the check valve nipple, and im considering pricing your deletion kit and valve cover job, but shes already been in deep with this cruze at 100k miles so im almost as likely to start washing my hands of it and let someone else grow into the bad guy lol.

And so, I came across your video and purchased your "GM 1.4L LUV/LUJ PCV Fix Kit V2" - kind of a h*ly sh*t moment after firing it up and running it with your kit on! It now runs like it did when I drove it off the dealership parking lot! Wow - just wow! Dre Dan's kit was the perfect fix for all my problems so at the very least, I thought I'd write you and again, say thank you! For a 100% failure rated part, the intake manifold with it's cheaply designed check valve...well, this is the way! It was also a good time to clean the throttle body and everything I had access to - a lot of built up crud as this was the first time having it apart since I bought it.

Do these failures occur or start to occur without throwing a code? If so, how do you diagnose it from instrumentation (e.g. turbo boost measurement) running an OBD device? I've been having oddly rough performance and subpar gas mileage since my dealer's 50,000 mile service a few weeks ago, and there was a bit of questionable idling before that which I chalked up to my usual spring routine of having very little highway driving and not even all that much city driving that time of year. I had dealer replace fluids (radiator flush, transmission flush) and flagged to them the possibility of a PCV situation; they did not find anything wrong on the PCV but did see a plug not quite all the way screwed in (corrected) and a boot on a plug wire slightly corroded (replaced).

Pull the spark plugs and pressure test the cooling system. Or, cylinder leak pressure test and see if any air in the cooling system. Either way, the two shouldn't do that. That's a breach.

Excelente explicación. Pienso que la válvula dentro del múltiple de admisión de mi Chevrolet Sonic RS 2013 1.4L esta atascada, pero no tengo la certeza. mi vehículo marca el código P1101. He reemplazado la tapa de punterías para descartar que el diafragma este averiado y revisando la válvula check en la manguera PCV hacia el turbo, encontré que el flujo de aire va en las dos direcciones, por lo que también reemplace esta manguera. Aun con esto mi vehículo sigue marcando el Código p1101. Observando por la toma del múltiple de admisión y después de limpiar con un poco de alcohol y un Isopo el área, se puede observar la pequeña protuberancia naranja, por lo que confirme que la valvula pcv sigue ahi. Pero supongo que esta atascada. mi vehículo no presenta ningún síntoma aparente, salvo el indicador de Check engine en el Tablero. También he notado un mayor consumo de combustible y ligeros restos de aceite dentro de cuerpo de aceleración. como puedo tener la certeza de que la valvula dentro del multiple de admision esta averiada o atascada? ya he encargado el kit de reparación para no tener que reemplazar todo el múltiple de admisión. pero si la valvula sigue adentro como la restrinjo? solo debo sacarla de su posicion para despues bloquear el paso de aire? un coordial saludo y gracias por tu video desde Tijuana B.C Mexico.

Pudiste solucionar tu problema? Hoy empezó a fallar mi Buick Encore 2017 1.4 Turbo, empezó con un ligero fallo en relay y empecé a escuchar mucha succión de aire en el diafragma de tapa de punterías, revisándola y escaneandola noté que igual me marca el P1101 que es MAP el problema realmente empezó cuando después de aproximadamente 1-2 horas de estar revisando, el turbo empezó a mancharse de aceite y empezó a sacar humo blanco por el escape, ni hace ningún ruido raro el turbo pero si empezó con estos problemas. Mi deducción es que el diafrágmame o ya sea el múltiple de admisión están permitiendo el paso excesivo de aceite al turbo y no es exactamente el turbo el que se daño, me serviría mucho tu opinión en caso de que se haya solucionado tu problema. Saludos

[@hanceljosuedlatorre1494]

​@@temeocero1411 que tal !!! Como no sabia si la válvula en el múltiple estaba oh no atascada opte por removerla, de cualquier forma es un a falla que eventualmente va a suceder por lo que me decidí a instalar el kit de baypass de la válvula de múltiple de admisión, pero, después de hacer el cambio mi auto seguía igual, marcando el mismo código. mi problema se encontraba en el cuerpo de aceleración, lo removí yo mismo y le di limpieza, la suciedad que tenia no permitía el movimiento correcto de la mariposa, por lo que el flujo de aire y gasolina no era el correcto. tuve que conseguir un escáner avanzado que me permitiera setear la calibración del cuerpo de aceleración después de manipularlo. y listo adiós al error. Por lo que tu comentas es posible que debas cambiar la tapa porque si hay vacio el diafragma esta rot, despuies de eso revisa el cuerpo de aceleracion y limpialo. espero que esto te sirva. saludos Hancel

Hello my GF just bought a 2014 Cruze and it has those problems I got a new cover ordered, I'm a dirt track race car mechanic stock cars and modified's, not a lot of experience with turbo engines. Question could I delete to pcv with a breather filter or no being a turbocharged engine?

[@TheAshleysofia33]

Great, easy to follow explaination of this system. P1101 does not go away on my car. The dealership replaced the turbo with new gaskets the first time. The second time they found a vacuum leak on the camshaft cover, third time came up after my battery died, and now I'm so fed up with this code! 4th time, all within 8K miles. Best part is, the code comes and goes as it pleases. I'm going to take matters into my own hands and replace the pvc hose to the turbo. Any other suggestions?

just bought a 2016 chevy Trax LS with this motor (Korean). It runs amazing but I was looking up known issues just to kind of pre research so that I can be prepared if something is to happen. This was super informative. Thank you. I subscribed just in case I ever have to refer back for issues. Thank you for the content. Is there any specific out of the ordinary tips or maintenance you would recommend besides the usual obvious oil changes and regular upkeep? Or maybe you already have a video about something like that? Thanks. P.S. I saw another gentlemen's video working on one of these and he recommended every other oil change that you change the Inlet Turbocharger Oil Line because it's located behind the heat guard and due to where it is located the oil gets clogged in that line and it causes your turbo to fail prematurely. I know Dorman also makes a replacement piece for that & it's inexpensive & an easy quick fix while changing the oil on the vehicle.

[@AndreiDPop]

How many miles? I would inspect the intake manifold for a missing check valve. Always run synthetic in the engine, AMSOIL is best and I can get it for you. Keep an eye out on the cooking components. They’re cheap but tend to fail. Coolant flush should have been done by now so if it wasn’t, get it done. A BNR tune would be a good idea as it will get you loads more power but also keep the engine a little cooler which will prolong the life of cooling components.

I have a 2011 Cruz. Did a leak down test and it leak at the back of manifold. Replaced it with new. The hose that goes from the intake to the turbo blows free one way and just a little air comes through the other way. Wondering if that is normal? Looked to see if i could can find the check valve in the intake. i saw something but not sure if its bad or not. Here's whats going on with the car. Taking off i get up to 3000RPM and the trans wants to down shift, If i get up to 3000 and let off the gas it shifts fine into the next gear. I've talked to others on different sights they say pcv problem. I also changed out the turbo. The scan tool code came up with bad turbo.. On all of the sights, I've haven't heard anything about shifting troubles and the pcv.

[@Thunderroad8517]

Is the valve cover gasket replaceable? Fixed a p0299 with a clip missing of the wastegate/disconnected. Now I have an oil leak. Replace the big hose with the two check valves because it broke when checking the little valve in the intake. Any thoughts would be great if you have the time. The oil leak wasn’t present prior to fixing the turbo clip. Thanks in advance.

[@andrewg2973]

Did it stop the noise ??? Have you drove a long distance since because it ate 5 valve covers because of defect. Ac compressor bolts backed out and there was a loud rattle and I think the squealing and whistle / siren noise was to do with that, new belt losts of ticking but thats fuel injectors . I got an appointment on 21st of February so i will comment and let you know what mine is doing to see if they can figure it out. There was a crack in flex pipe twice so replaced it and with new toyo tires handles and drives a million times better fixed alot of jerk out when I hit the breaks when car starts before it is warm, I hope my comments help I ramble on but the mechanic said it was 1 of the smoothest running cruzes around 😊 also throttle body and intake manifold were done with crankshaft seal at 93 k but manifold was done a second time, hot water valve failed 2 times but high test gas and change oil when it is dirty or smells like gas if it is down add a little but you need to change it. When my turbo went I am pretty sure it was the waste gate but I could only do 100km even at 5000 rpm and mechanic could not touch it for 2 hours so check anti freeze and oil like i said basic maintence and any noise from engine ask a friend or a random person can you hear anything, mechanics dont want to diagnose they will change something they think is wrong but it wont fix the problem unless they know and have common sense also wash your car and check air filters behind glove box and engine filter I had mice babbies behind glove box got a washable k and n filter but good luck and take it on highway or parking lot hold traction control for 20 seconds untill both lights are on foot on brake and one on gas first gear ebrake on rev car for 5 to 10 seconds let go of brake put handbrake down and spin those tires get the car working abit burn that crap gas out needs high test and brake and gas will go to 1500 rpm traction off it will go to 2500 rpm it just needs to be driven stop and go but get on highway and open it up it should go from 100 to 120 when you floor it when you give it gas it should shift and pick up speed, when we first had the car it didnt have power from 100 to 120 now I can easily hit 130 i floor it to speed limit and it and if I hold the gas down a bit it will go to 50 then 60 70 80 in no time just drive it like you stole it, it needs to be driven and cleaned out you should not need a new cat I was told twice but it was flex pipe both times car gets hot to but there is a reason if your cruze runs rough or is crap it is one of the funest and best cars I have drove i leave every one at the lights they pass me but thats cuz I let off gas at 50 and dont want to be that guy that does 100 in town I have got to 90 like just have some fun and find a good mechanic or come to me and I can let you know what I think cus yeah love hate relation ship but it works when you fix it and do basic maintenance

[@maltebursing1124]

Hello Dre Dan, i have a strange noise in my opel corsa with 1.4 turbo motor from 2014(its the same motor as in the cruze), when its warm an its no belt driven part - i checked it without the belt. I checked the PCV valve to the turbo, its switching when i blow in an suck there and i can see the nipple in the intake and the valve cover isnt sucking air. But i have the simmer ring squeeking when i shut off the engine and a noise like a sqeaking belt when its warm. Is it possible to have a higher underpressure on the enginge caused by the valve cover? I first want to change the simmerring but if its not the solution for it i maybe want to change the valve cover. What do you think? The next step could be an expensive change of the timing chain. Sorry for my bad english ;)

Good job with the custom PCV. Hey I have been experiencing on occasion , gasoline vapors when at idle with heater fan on only.

Any update on how well the Dorman intake manifold works?

[@lightsoforion7699]

Would this cause white smoke out the exhaust as well? I've got the p0171 p0106 p1101 codes and the disc thing on top of the valve cover is indeed sucking air and I cant see the orange nipple in the intake manifold. I wasn't concerned about it until I noticed it's white smoking but it doesn't smell like oil or coolant. Just smells like regular exhaust fumes but is thick white clouds when first starting up then it eases off a little.

[@pgriffiths88]

Would this problem result in coolant leak anywhere? Trying to determine if I'm having a head gasket problem. Thank you!

[@RGL642]

Hi Dre Dan awesome video and explanation. You and one or two other guys have similar fixes. What is the hose mounted on top of your valve cover, where does it go and what's it for. Have you made a video showing and explaining that setup. I'm having all the same issues you had and this will be the second time I've replaced the VC.

[@AndreiDPop]

I'm the only one that has the PCV fix kit. There are a few guys who have attempted something different as an adaptation of one of my designs, but there are flaws with each approach. For as simple as my solutions look, they're actually quite complex, and a great deal of time was spent during research and development. Even the epoxy selection took me two weeks, spending hours each day with engineers at loctite and jb weld discussing technical requirements. Did you address the intake manifold check valve failure? If not, the valve cover will fail prematurely.

[@RGL642]

@@AndreiDPop I have not fixed the issue yet but want to, I just want to make sure what you have for a fix is actually true and a correct fix. You still did not answer my question to the hose installed into your valve cover, please see my last post. I want to do this one last time and fully correct the issue (GM sucks. Any info on installing a dual inlet ketch can and a throttle body spacer. Is that something you have done on your kits. I've seen another video from Spool_Time doing a similar setup. I want to install the best setup possible for all these cruze issues. Thank you for your time.

[@AndreiDPop]

@@RGL642 the fix kit I designed (all three versions, actually) address the intake manifold check valve failure. The valve cover will continue to fail but should last 60k-80k miles or more between failures if the intake manifold is working correctly. It's a true fix as it plugs up the hole where the old check valve used to be and relocates a new check valve externally. You can order any one of them from cruzekits.com. As for the other question, apologies as I forgot to reply to that. That's an AMSOIL single remote bypass filter. Superfine particle filtration and adds 1 quart extra capacity to the oil system. Bit expensive but I've found it reduces wear and allows me to operate more safely under extreme conditions. For example, I've been towing my 6x1 trailer for the last 8 weeks every day, pulling anywhere between 600 pounds empty to 1750 pounds loaded. This is while pushing 24psi of boost on a BNR GTX14 turbo and running e85, with stiffer valve springs. . Far more power than stock. I don't really believe in catch cans, and here's why. While tuned and driving the car hard, I had to add 1/4 a quart to my car in 15,622 miles of driving on a single AMSOIL oil change. That was before I added the bigger turbo and e85. With oil consumption that low, with the pcv system working properly and running a super low volatility oil like AMSOIL, I struggle to find any tangible benefit to a catch can. Now, I am working on a boost path vacuum pump mod that will further improve piston ring seal under boost, which will provide some tangible benefits. You can run a dual catch can setup with a throttle body spacer if you want to. I just don't think you'll see to much benefit. A super low volatility oil will make a bigger overall difference.

[@AndreiDPop]

@@RGL642 also worth noting, with my v3.4 kit, you can run a single catch can in such a manner as it would filter both boost and vacuum paths. Pretty simple setup that would eliminate the need for two catch cans and the throttle body spacer if you really did want to run one. It would require just a few slight modifications to the kit design. But I could easily make those and include it as a drop-down option on the v3.4 kit page.
