Amazing a Buick and Chevy with a K as the first character in the vin number, a pcv valve that is a valve cover , and a non return valve that is a an intake manifold. American cars that do not identify as American cars and parts that do not identify as the parts they should be. Automotive wokeness. The diagnosis repair and was excellent . These cars are pieces of S#!T
A very very common problem I've done hundreds of them, those motors are a POS on a good day so it's no surprise they have so many problems, just your usual "quality" GM (General Mess" product.
It's the same story over and over with this engine. There's a guy on here named "Dre Dan" channel-- Look up his "V3 PCV fix" for this 1.4L. He seals up those internal holes, and then drills and adds a more industrial valve on an external line-- that's easier to change and virtually never breaks anyway. It's a great alternative to buying a new intake. Because I was not going to buy a whole new intake, just because it's missing that silly little silicone flapper on the inside- which will just fall out again. (disgusting design). They should have at least added a little window/ removable lid with two screws where you could each down in there with a new silicone flapper valve, without taking off the entire intake.... anyway, the "version 3 (v3)" fix is a sweet little kit and makes this engine 10x more reliable; because as long as that valve holds up, they PCV doesn't go bad, typically. If you do these a lot, you might look into it.
Go ahead and reinvent the wheel... or PCV valve & intake system in this case. Just don't do it with cheap plastic components... Right? So I think I've figured out why they do this in mimic of BMW's plastic engine bay strategy. After watching a recent interview with Elon Musk about his meeting with Daimler Chrysler in 2009, I think manufacturers do this kind of planned obsolencence BS on purpose. In that interview (in Germany) he was told by a successful car industry investor that the car makers who actually make it, do so on the volume of used cars on the market by selling high mark up parts for them. The new car sale doesn't make you money and maybe you lose money on it, but the parts with the fixed costs already spent can have very low variable cost and higher margins (easy money with stable longer term yields). This is why so few new car companies have been able to succeed in recent times. They have no volume of used cars to make that sweet, sweet low cost/high mark up parts money. US car companies have to be required by law to carry parts for the cars they sell for 10 years. And many like Chrysler stop carrying them after that. In contrast, I still by factory Toyota parts for my 24 year old Tacoma. You know who loves Toyotas? The whole world does!

You test it with a smoke machine. Blow smoke into the intake… smoke will come out of that hole in the diaphragm indicating you need repair kit for the pcv or a whole valve cover
Disgusting isn't it. All it needed was a little window there with two screws, where we could reach in with a new silicone flapper and pop it in place, and then screw the cover back on. but no, They want to sell parts; and a 10 cent piece of silicone flapper isn't going to make them any profit. It's embarrassing really. This is why I only buy Honda or Toyota.. other than Ford trucks.
Can GM get any more pathetic. Disassemble the top of engine for PCV issues. Never should have bailed them out. And I used to work for and only drove GM products, before this abortion happened.
I knew what it was going to be only because I've done them. It's nice to watch someone else work :). Your explanation was simple enough to be given to a customer and detailed so that it didn't go over anyone's head. Nice video, thanks.
@@GoTechTraining Knowing now that it's rubber, I worry less about it roaming around in the engine. I'm the guy that searches for hours for the dropped screw that didn't hit the floor. It's not the cost of the screw that worries me. it's the damage it might do to what ever it gets into....Thanks....

There's a guy on youtube that has made an aftermarket fix for this intake valve.. You actually glue in a plug and seal up those existing internal holes--- then you drill a new hole and put a valve on an external line---- at least this way you can replace it easily later. It's a pretty sweet little kit and makes it 10x more reliable than buying a new intake, just because a little silicone flapper fell off. What a terrible design. This engine makes me angry at the engineers. lol
@@GoTechTraining His channel is "Dre Dan" -- and he had made iterations of his repair kit. Last I checked the V3 (version 3) was the most recent. Just search his channel for "v3 pcv 1.4L"
How often do the intake manifold check valves fail? These are kind of expensive parts and jobs to fix too frequently. Have had this happen twice in 10k miles but only needed to change the valve cover previously. Orange nipple was still in the intake but engine still failed and leaked and threw codes and drove badly.
Hey Max Ax, this is a pretty common issue on this engine. I'm not sure that it should be failing again so quickly after it was repair though. Maybe something went wrong? ~Mike
@@GoTechTraining well I stupidly tried cleaning that intake hole or tube with it with the metal cleaner provided in 1 of the latest PCV fix kits, and then after that I looked and it was gone. Didn't check before. But I only tried it because I did an oil change and noticed some leakage around the top of the valve cover on the outside facing the front of the car. Maybe it was gone already to cause that, maybe not. But even the last time the valve cover was totally bad and leaking, and the car ran crappy and threw 3-4 CEL's the nipple was still there.
Just replaced the valve cover today. Be careful of the two corner bolt holes that are in the timing cover. The aluminum seems to be softer. Both stripped out when removing them. Had to drill out and heli coil both holes.
Discovered an oil leak coming from those two bolts today, replaced my valve cover yesterday. I am so sick of this car. Looks like it is helicoil time for me too.
Great video, as stated by others in the comments, so many people replace their valve cover and have to replace the front mail seal that also failed, but never resolve the core issue which is in the intake manifold. As far naming goes, alot of people, including myself, call the non-return valve in the intake manifold the pcv valve. But thats just semantics. Once again, great video.
7:17 at this point tighten those 2 external torx bolts that hold down that upper timing chain guide. Those bolts have been loose on every single 1.4 IV done a valve cover and intake mani on.
Great video. There are so many video's out there telling people to just replace the valve cover and gasket. As you have explained it's the intake manifold. I have had great success with the updated Dorman intake manifold. Dorman 615-380 Lasts much longer than the oem. Thank you.
The two trouble codes should not be related. Did you clear the codes after replacing the thermostat? The P0599 is a circuit code, so make sure to check your wiring and PCM control for the thermostat. With the P0171 lean code, I would start by checking the PCV valve as demonstrated in this video. I hope this helps! ~Ryan
Very good showing what was wrong and how to fix. I have a po171. & po458. Codes. Took it to technician who said it's the purge valve. ? He said part & Labour will be £231. ? Does that valve sound right ? P. P.
I just had 2 questions, what is the mileage on vehicle and there is a kit that caps off where the orange valve falls off. In ur opinion would you use the kit or change intake manifold? Thanks for the video any feedback appreciated
I used the Cruzekit to replace the check valve on my 1.4 and it permanently solves a design flaw. Very easy to install, seller has an excellent video. Way less expensive and much better end result!
Hey William, We flash a few pics of the new intake here th-cam.com/video/F9Arl6vEBJY/w-d-xo.html Sad part is the part design is not updated and it is the exact same design as the failed intake.

Crap..... Always something with these 1.4 turbos.. working on a 2014 cruze just replaced a cracked head from overheating.. along with timing set water pump thermos. Im about to go finish up and install exhaust manifold/turbo and the intake until i saw this video, im pretty sure thay non return valve is gonna be shot on my project too
Hello, As of now, they have not updated the intake manifold. They do sell it by itself now, you used to have to buy it with the throttle and injectors attached. ~Ryan
What do you call SUBSTANTIAL and KNOWLEDGEABLE and PRODIGY The answer is Go Tech Ryan Wilsing Sharing what you know with us Thank you very much helpful information video Tutorial great👍 thank you Have a great day and take care Can't wait when you how you carry out Voltage drop testing Go Tech Ryan Wilsing From Nick Ayivor from London England UK 🇬🇧 ⏰️ 21.39pm
It’s often a broken return valve in the crank case that causes the diaphragm to rupture. If you just replace the PCV cover and the return valve is still broken, they’ll be back in in 2 months.
What happened to the non return valve that was in the old intake?? If it fell out and allowed boost pressure into the crankcase, where did it end up... or did I miss that part?
yeah.. It's just a little piece of silicone that acts as a one way flapper. It falls out and you have no way to get in there to add another one--- so they just make you buy an entire intake, when all you need is a little 10 cent piece of silicone. Such a poor design; and it will fall out again --- just you wait.
@@calholli Dorman makes an aftermarket intake that has a pointy bit that prevents the valve from being sucked away into the nether regions of these 1.4s.
I haven't watched yet-- but I bet it's the pcv on the top cover... My sister had this same issue. You have to buy the entire cover just to fix it. And also, there's a little silicone valve inside the intake that can go bad--- and then you have to buy an entire intake just to fix it. This engine is terrible.
If that boot was missing in the Intake, would it cause white smoke to come out the exhaust pretty heavily? Even after replacing the Valve Cover with OEM? Or do you think thats more or a turbo issue?
Not bad….not bad at all! You’re no Mike Becker (you know…..THE Mike Becker) but you are pretty darn good. Thanks for sharing the excellent tip on checking for the missing non-return valve!
@@GoTechTraining I hope you know that I was joking regarding the Mike Becker comment. Of all the Mike Beckers in the world, he’s the best Mike Becker (and the most intelligent) of all! You’re a great addition to the channel and I look forward to additional content!

Hello, It can be expensive due to the part cost and labor. It is listed at around 4 hours of labor, so the cost will depend on the shops labor rate. ~Ryan
What would a job like this cost at a dealer and can another auto shop know how to work on these! I have a strange situation, i have 2016 cruze with 2nd gen 1.4L / turbo and i have a 2020 trax 1.4L 1st gen ( strange)
Not sure on cost, really depends on labor rate and part cost. But this job is pretty straight forward and can be done with a few sockets and hand tools. I think another shop should have no issue with this repair, if they do engine repair as a service ~Ryan
Hey Earl, thanks for watching! Yeh, this engine sure has it's issues. I can think of a few others that rank as high as this one too. Ford 5.4, GM 3.6, Chrysler 3.6, I'm sure the list goes on if we kept thinking about it lol. ~Mike
Can I ask at what mileage the orange 🍊 pcv inside the intake manifold fails? They were telling me dorman parts has a intake manifold that is better than factory manifold. Thanks for the video any feedback appreciated
@@GoTechTraining well, I did the pcv valve check, using piece of paper like you showed on your video, and pcv valve was good. after I removed the code with my OBS machine, it turned out check engine never came back !!! thanks again for your help
Hey Carlos, you're right, it is a diaphragm but it does the same job as the traditional pcv valve. GM calls its a crankcase pressure control diaphragm in service info. Diaphragm valve different operations, same result essentially. Thanks for watching! Mike Becker, Senior Instructor
It's crazy! The Opel Mokka ist one of the best selling cars from Opel that days. No one knows this problem, and i fixed it all! The intake-sealing, the throttle, the map sensor, the injectors, the ignition coil because of the misfire... I needed the car for work so I drove and drove and drove. So i destroyed the sparkplugs because of the high heat. Thank you very very much for your help 😎 I thought the engine's down, but you rescued me!
I changed both out today and have that code p0171 come up with a little hissing from the pcv hose …. I didn’t check the o ring …. Good looking out I’ll do it first thing in the morning
Hello, I've got P0171 and P1101 faults on my 1.4 turbo. I checked the non-return valve in the intake manifold, the oil separator membrane and the non-return valve in the turbo hose which was bad. I changed it with an used one, but it passes little air from the turbo side ( you can barely blow the air from that side in to the hose). My question is: should I bother to buy a new hose for 50eur? Could the system even feel such a small amount of air coming from the hose and turn on the check engine light?
Changing the valve cover only pushes the problem down the road about 20k miles and it will happen again. There is a bypass that will eliminate the valve cover problem. Replacing the intake will also only push the problem down the road. Get on Cruze Talks and look for Cruze kits. This will prevent either part from ever failing again
Hello Skildude, I have heard of work around kits that people have been using on these engines. I'll have to check it out. Have you had any luck with these yourself? ~Ryan
Great video! The mechanic changed in my A14NET: intake manifold, valve cover and this pipe from intake to turbo. Unfortunately I have high positive fuel trims on idle (about +25%) and P0299 (underboost) error. The turbochanger is new, the is no airleak, and the EVAP valve seems also OK. Do you have any idea what would be the problem with P0299 and high fuel trims?
@@PAYASLRF Hello! Thank you for your feedback! The turbo is back on my Astra. It came back for itself after about 3 weeks. It was probably intercooler sealants (I have changed them). By the way I also replaced vanos sensors. Now my Astra drives smoother.
As soon as you said a bounce of tsbs I called it but I wasn't expecting that valve. I had a car come in about 11 months ago and wish I looked harder at the tsbs. I have a filling that valves missing just because its same motor with turbo and the lady drove it so long it was bad. In my defense I was already fimialer with this issue but the more I think about it I dont believe it was a turbo the first time I seen this. No excuse I should of did research. Sometimes your busy you've seen the symptoms before, you do your testing fix it and ship it without getting in to tsbs. At least I know now.
GM also made it a little confusing with having several TSBs for the same problem. I think only one of them mentions both issues in the same TSB Thanks for watching! Ryan W, Technical Instructor

That's a good question, I have never found one that has fallen out. The valve is made entirely of rubber, so most likely it is just consumed by the engine Ryan W, Technical Instructor
@@GoTechTraining well, I guess that answered my question, didn't realize it was just a rubber valve, thought it was an entire assembly. Hope it dosen't wrap itself into the turbo exhaust impeller. thanks.
@@mthompson1637 It's literally just a flat piece of rubber/ silicone-- with a little nipple in the middle to hold it in place-- yet you can't get to it to replace it-- so they make you buy a whole new intake, instead of selling the 10 cent rubber flapper. Embarrassing design.
i just figured out the pcv was leaking vacuum and wasn't happy about having to replace the valve cover. now i have to check and see if the intake's shot too. good to know

Im about to go finish up and install exhaust manifold/turbo and the intake until i saw this video, im pretty sure thay non return valve is gonna be shot on my project too
Yeah they are a very common failure, but easy to diagnose at least.
Thanks for reaching out!
~Ryan
Do you know when they updated the manifold got a 2018 trax just curious if I'm going to have this issue
Hello,
As of now, they have not updated the intake manifold. They do sell it by itself now, you used to have to buy it with the throttle and injectors attached.
~Ryan
Great tip on replacing the intake manifold along the PCV/valve cover! 👍
Thank You!

Great video. May I ask what did you disconnect in the fuse box and why?
It’s always good to use paper it’s old school way for pcv. We used to check on oil dip stick tube
Nice cheap and available tool! I still use dollar bills on the exhaust from time to time!

Buenos dias, el video me ha resultado util¿ me podria decir cual es par apriete en Nm de la tapa balancines?
All you had to say was your car is a piece of shit don’t try to fix it yourself if you aren’t a mechanic 😂
We have the same issue with the vauxhalls here in the uk, even on non turbos.
It’s often a broken return valve in the crank case that causes the diaphragm to rupture. If you just replace the PCV cover and the return valve is still broken, they’ll be back in in 2 months.
What happened to the non return valve that was in the old intake?? If it fell out and allowed boost pressure into the crankcase, where did it end up... or did I miss that part?
My question also. Where do we look for it ??? Did the missing valve fairy carry it off ??
yeah.. It's just a little piece of silicone that acts as a one way flapper. It falls out and you have no way to get in there to add another one--- so they just make you buy an entire intake, when all you need is a little 10 cent piece of silicone. Such a poor design; and it will fall out again --- just you wait.
@@calholli Dorman makes an aftermarket intake that has a pointy bit that prevents the valve from being sucked away into the nether regions of these 1.4s.
@@TheGNexus I looked it up.. That's an interesting fix.
Unlike here, ALWAYS remove the ground connection on the battery.
I haven't watched yet-- but I bet it's the pcv on the top cover... My sister had this same issue. You have to buy the entire cover just to fix it. And also, there's a little silicone valve inside the intake that can go bad--- and then you have to buy an entire intake just to fix it. This engine is terrible.

@@RowdyEnt. That just means the guy before you already fixed all these issues.
@@calholli I bought them brand new. Soo I doubt that.
@@RowdyEnt. Yikes.. Paying new cars prices for a Cruze. ouch
@calholli I bought it in 2011 and the sonic 2015. Was alot less then you think. Also got a 2014 f150 back then for 25k cdn brand new. Shop around.
If that boot was missing in the Intake, would it cause white smoke to come out the exhaust pretty heavily? Even after replacing the Valve Cover with OEM? Or do you think thats more or a turbo issue?
Not bad….not bad at all! You’re no Mike Becker (you know…..THE Mike Becker) but you are pretty darn good. Thanks for sharing the excellent tip on checking for the missing non-return valve!

How many $$$ at the dealer is this going to cost...valve cover&intake manifold, is this many hours of labor???
Thank you..
Hello,
It can be expensive due to the part cost and labor. It is listed at around 4 hours of labor, so the cost will depend on the shops labor rate.
~Ryan
Great video! How many miles were on the Buick Encore at the time of repair?
What would a job like this cost at a dealer and can another auto shop know how to work on these! I have a strange situation, i have 2016 cruze with 2nd gen 1.4L / turbo and i have a 2020 trax 1.4L 1st gen ( strange)
Not sure on cost, really depends on labor rate and part cost. But this job is pretty straight forward and can be done with a few sockets and hand tools. I think another shop should have no issue with this repair, if they do engine repair as a service

Not necessary to find where the missing boost check valve went? Or, did I miss something?
The boost valve is made of rubber and most likely is consumed by the engine

Hey Earl, thanks for watching! Yeh, this engine sure has it's issues. I can think of a few others that rank as high as this one too. Ford 5.4, GM 3.6, Chrysler 3.6, I'm sure the list goes on if we kept thinking about it lol.
~Mike
The loud music sucked
Can I ask at what mileage the orange 🍊 pcv inside the intake manifold fails? They were telling me dorman parts has a intake manifold that is better than factory manifold. Thanks for the video any feedback appreciated
wow, that's what you call it ''simple'' diagnosis... not for me, I'll pay for a mecanician, thanks anyway, nice video !
Hey Richard,
The diag is simple, the repair is a little bit tougher.
Thanks for watching and glad you enjoyed the video!
~Ryan
@@GoTechTraining well, I did the pcv valve check, using piece of paper like you showed on your video, and pcv valve was good. after I removed the code with my OBS machine, it turned out check engine never came back !!! thanks again for your help
Of course !
Sorry, but that is not the pcv valve. It is only a diaphram. The car has two pcv valves, but that is not it.
Hey Carlos, you're right, it is a diaphragm but it does the same job as the traditional pcv valve. GM calls its a crankcase pressure control diaphragm in service info. Diaphragm valve different operations, same result essentially. Thanks for watching!

Greetings from Russia! I have Opel Meriva B with the same engine. Tomorrow ill be fix that problem with valve cover. 10X!
It's crazy! The Opel Mokka ist one of the best selling cars from Opel that days. No one knows this problem, and i fixed it all! The intake-sealing, the throttle, the map sensor, the injectors, the ignition coil because of the misfire... I needed the car for work so I drove and drove and drove. So i destroyed the sparkplugs because of the high heat.
Thank you very very much for your help 😎 I thought the engine's down, but you rescued me!
I changed both out today and have that code p0171 come up with a little hissing from the pcv hose …. I didn’t check the o ring …. Good looking out I’ll do it first thing in the morning
watch out mike the new guy migth take over lol

I have 2015 Cruze and oil in the air intake and no vacuum on the turbo lines
How hard is it to replace the pvc bipass hose if it is cracked?
Everyone do your self a favor and just buy Honda or Toyota!!!
Which RTV sealant do you use? Thanks
Permatex Black or Gray. Black has better oil resistance. Gray has better torque holding qualities.
John nailed it, I used the permatex grey on this car.
~Ryan Wilsing
How about the MAP or MAF sensor?
Will you guys do any hybrid videos??

Yea pretty much what data pids to look at? How to test the big orange cables. And how’s the electric motor work between the trans and engine
Hello,
I've got P0171 and P1101 faults on my 1.4 turbo. I checked the non-return valve in the intake manifold, the oil separator membrane and the non-return valve in the turbo hose which was bad. I changed it with an used one, but it passes little air from the turbo side ( you can barely blow the air from that side in to the hose). My question is: should I bother to buy a new hose for 50eur? Could the system even feel such a small amount of air coming from the hose and turn on the check engine light?
I got this dis you ever resolve it?
Hey, what RTV did you use? Thanks
Great video. Where's Mike Becker today?

What a daft design
It's embarrassing. lol
I think the concept is good, but I agree it was poorly executed
I guess all cars have their issues
Thanks for watching
Ryan W, Technical Instructor
Changing the valve cover only pushes the problem down the road about 20k miles and it will happen again. There is a bypass that will eliminate the valve cover problem. Replacing the intake will also only push the problem down the road. Get on Cruze Talks and look for Cruze kits. This will prevent either part from ever failing again
Hello Skildude,
I have heard of work around kits that people have been using on these engines. I'll have to check it out.
Have you had any luck with these yourself?
~Ryan
Very nice 👌
Great video! The mechanic changed in my A14NET: intake manifold, valve cover and this pipe from intake to turbo. Unfortunately I have high positive fuel trims on idle (about +25%) and P0299 (underboost) error. The turbochanger is new, the is no airleak, and the EVAP valve seems also OK. Do you have any idea what would be the problem with P0299 and high fuel trims?
Hello did you checked the vanos sensors?
@@PAYASLRF Hello! Thank you for your feedback! The turbo is back on my Astra. It came back for itself after about 3 weeks. It was probably intercooler sealants (I have changed them). By the way I also replaced vanos sensors. Now my Astra drives smoother.

As soon as you said a bounce of tsbs I called it but I wasn't expecting that valve. I had a car come in about 11 months ago and wish I looked harder at the tsbs. I have a filling that valves missing just because its same motor with turbo and the lady drove it so long it was bad. In my defense I was already fimialer with this issue but the more I think about it I dont believe it was a turbo the first time I seen this. No excuse I should of did research. Sometimes your busy you've seen the symptoms before, you do your testing fix it and ship it without getting in to tsbs. At least I know now.
GM also made it a little confusing with having several TSBs for the same problem. I think only one of them mentions both issues in the same TSB
Thanks for watching!
Ryan W, Technical Instructor
It's the same story over and over with this engine. There's a guy on here named "Dre Dan" channel-- Look up his "V3 PCV fix" for this 1.4L. He seals up those internal holes, and then drills and adds a more industrial valve on an external line-- that's easier to change and virtually never breaks anyway. It's a great alternative to buying a new intake. Because I was not going to buy a whole new intake, just because it's missing that silly little silicone flapper on the inside- which will just fall out again. (disgusting design). They should have at least added a little window/ removable lid with two screws where you could each down in there with a new silicone flapper valve, without taking off the entire intake.... anyway, the "version 3 (v3)" fix is a sweet little kit and makes this engine 10x more reliable; because as long as that valve holds up, they PCV doesn't go bad, typically. If you do these a lot, you might look into it.
@@calholli I'll check it out thanks.
Thenyou so much my friendo to good information to us gracias mi amigo por enseñarnos ya me sus cribi a tu canal your chanol saludos .
Maybe more about the valve. As M Thompson asked, "where did it go ??" Should we be looking for scrap metal somewhere ? Thanks.
That's a good question, I have never found one that has fallen out. The valve is made entirely of rubber, so most likely it is just consumed by the engine
Ryan W, Technical Instructor
@@GoTechTraining well, I guess that answered my question, didn't realize it was just a rubber valve, thought it was an entire assembly. Hope it dosen't wrap itself into the turbo exhaust impeller.
thanks.
@@mthompson1637 It's literally just a flat piece of rubber/ silicone-- with a little nipple in the middle to hold it in place-- yet you can't get to it to replace it-- so they make you buy a whole new intake, instead of selling the 10 cent rubber flapper. Embarrassing design.
How did you start the engine without stepping on the brake pedal?
i just figured out the pcv was leaking vacuum and wasn't happy about having to replace the valve cover. now i have to check and see if the intake's shot too. good to know
