Thank you for finally posting a video on the 1.4 pcv isue. Everyone thinks it's the valve cover and I too replaced mine. I had oil coming out everywhere. Did some research and replaced my intake with the Dorman brand and no more oil leaks. Wish more people knew about the problem with the stock intake. Great video.
I’ve received a letter regarding the pvc intake manifold failed from GMC, i’ve noticed i have oil leaks all over my engine and whistling sound when i pull the oil dip stick out, I was told I need my crank shaft seal replace not knowing that was the cause, I took to GMC dealership to have it replaced, they did not mention what cause it, thanks for posting this video, now i will get GMC to reimburse the cost.
@@southfloridagearheads now i need to go back to the dealership and have the pcv issue fix, i just wonder why they didn’t noticed it, again thanks for posting this video!
It's supposed to run with the case in a vacuum. The seals blow because without the check valve the case is exposed to boost from the turbo, and that's what causes the seals to blow and oil to leak.
mine isnt a turbo model. can it be the same issue chevy sonic 2015 1.4. also losing oil now but i was hoping it is just blow by. i see no leaks. should i prepare to change seals as well?
I noticed my Buick Encore with the same engine smelled like hot Mobil 1 when I got out after driving. I looked at the check valve in the intake manifold and it was gone. I also have a check engine light. The code I read is P0299, low boost. I'm hoping fixing the PCV valve and the intake non return valve (what GM calls it) will fix it. I downloaded a GM service manual and it kept referring to the MIL. After quite a bit of searching, I found out that's the Malfunction Indicator Light, aka Check Engine Light. It will forever be the Mother In Law light to me.
low boost might be something different. this car had to have the turbo done around 55k miles. I think they are prone to waste gate failure and cranks in the exhaust housing. good find on the GM service manual I've been looking for one. MIL light yes hahha
@@southfloridagearheads I wish I could tell you where I found the manual, but it's been a couple years. It's a large file, 481,129 KB. I also got a complete electrical manual. I'm aware that this is not necessarily the entire problem. One thing I found in the manual is that when you change components in the intake system, you should do an intake system learned values reset. I bought an Autel MaxiCOM MK808BT PRO scanner. Autel customer service told me this unit would do that reset, but so far, not. There's a menu that lists it, but I get an error code. Autel has been working with me to resolve this issue.
The tech at chevy meant there isnt a pcv you can just change you have to replace the valve cover. The valve in the intake is called a non return valve. When you talk to techs at the dealer specially the ones that have been there for a long time use exact terms for instance this style pcv in the valve cover is widely called an oil seperator if you said that to a chevy dealer they would say idk what that is. When I worked for a new car dealer I asked for butt connectors for a wiring repair and the guy at the parts window had no idea what i was talking about then i explained and he said oh you mean salmon connector. If i call the dodge dealer for a vent vave you gotta say leak detection pump or they have no idea what ur saying.
Good video. If you had googled the common faults for this engine, you would have found a ton of info including the turbo breather pipe. Also could you tone down the rock music, its hard to hear you :)
I've got the same engine in my Astra J 1.4t. Next mod is an induction kit :) don't suppose you have any advise with the throttle body leaking oil? I've checked the manifold, oil separation and turbo pipe and all valves are good
Did you have any more oil leaks After replacing both I just did it to my car and I think I'm still leaking oil when I move concerned that it might be the oil Pan because it's all on the same side like yours flinging around on the belt I never thought about it being the crank seal
at idle or light throttle when there is vacuum if should suck the vapor from the valve cover and direct it to the intake. under boost the check valve in the intake should close and prevent you from pressurizing the crankcase. white smoke usually means burning coolant. any change in the level?
If I understand the sequence of events, you replaced the valve cover after the diaphram failed, but then problem with the oil leakage ensued. Then you replace the intake manifold. But did you have to replace the valve cover a second time after replacing the intake manifold?
no, caught it early enough before the valve cover diaphragm blew a second time. I think If the check valve isn't in the intake when car goes into boost it will blow pressurized air into the crankcase system and eventually blow out the valve cover diaphragm, crankcase seal. etc.
@@jma2022 hi. My car is running fine, no errors, with the pcv fix kit! I had P1101, but it was because of the trottle body. I've replaced it and now is fine.👍
One thing no one seems to have mentioned is that you can check to see if the orange nipple is still intact inside the pcv valve on the intake manifold, simply by removing the hose, then shining a light inside. If you see the orange nipple, it tells you that the pcv valve is still intact and working. The valve, or what I like to describe as a "flapper," is connected to the orange nipple, and resides on the other side of the intake manifold. Without the nipple, the flapper simply falls off. This is kind of what a flapper on the bottom of a toilet tank looks and operates like.
@@southfloridagearheads The first 2 times all in the side of the belt side, a lot of oil, after that we change the valve cover for the 3rd time and now it’s leaking only on valve cover
This was the best explanation of the whole issue. Thanks for posting.

It should come back after a year or 2 though with the same stupid design & material for the check valve in the intake
I have oil (in front) everywhere, and sometimes comes a strange smell unlike a burnt oil or antifreeze..

even the dealerships don't know. I bought my parts there and talked to the tech and he didn't know thr pcv was in the intake manifold

@@edab1253 Dealership mechanics are commonly incompetent.
Yes gmc is fuxked up with this plastic bullshit
Cruzekits has the kit to fix all this nightmare surprised you don't know about the orange knub and sealing it.
Thank you very much oh man this is your outstanding and I don’t know what to say but thank you for your knowledge and your expertise
Thanks for sharing your findings. You taught me something today.
Im just hoping this fix will last! there seems to be a lot of issues with these little engines.
Good job diagnosing that check valve issue.
But you have to use a fix kit on the manifold also. There are 3 options. If you don't, the Dorman fails again also.
Did he not do this?
Fails entails? Leaks codes drivability?
Yep Cruzekits has it his name is Andre
It's supposed to run with the case in a vacuum.
The seals blow because without the check valve the case is exposed to boost from the turbo, and that's what causes the seals to blow and oil to leak.

@@DG-hr9ye sounds like your turbo seal is leaking. Is there oil in you intake track as well?
@@southfloridagearheads can you give an update? Did it stop leaking?
@@KRC-es1xi no further issues almost 100k miles on the car now
Andre at Cruzekits has options for this fix with his kits.
Hi buddy, additional to that intake check valve does it there other pcv in that engine?
Did you have any more oil leaks After replacing both I just did it to my car and I think I'm still leaking oil when I move concerned that it might be the oil Pan because it's all on the same side like yours flinging around on the belt I never thought about it being the crank seal
yeah i think i need to do the front main seal behind the balancer.
Would this cause oil to pulled into the intake? I replaced the valve cover gasket and the water inlet and now it's blowing white smoke..
at idle or light throttle when there is vacuum if should suck the vapor from the valve cover and direct it to the intake. under boost the check valve in the intake should close and prevent you from pressurizing the crankcase. white smoke usually means burning coolant. any change in the level?

@@southfloridagearheadsthe checkvalve like you name it is the same that pcv or does it 2 things diferent?
Hi..did you car blow thick white smoke? Mine is..
no, white smoke is usually coolant
Where does the orange check value go? I took mine off and it is not there.
No idea.. did u find it?
It gets eaten by the internal engine components or burnt up out the exhaust.
Do you have the intake manifold part number? I have a Opel Meriva B(2011) 1.4 88kw(120hp) A14NEL. Thanks
Are you still looking for a new intake manifold for you opel? I just replaced mine with the cruze intake with some simple mods to make it fit.
@@jma2022 hi. My car is running fine, no errors, with the pcv fix kit! I had P1101, but it was because of the trottle body. I've replaced it and now is fine.👍
Did this fix it? Heard these fail just the same as the oem ones
possibly. if yours is blown out just get the fix kit. probably better off in the long run
They claim they don't but........ I put 6 covers on mine before learning what was real problem

@@CarlosGarcia-ls4hn Good point!
@@CarlosGarcia-ls4hn Hey great point but can we not just buy and replace that orange nipple thing instead of buying whole manifold?
Unfortunately not. It's fitted from inside the manifold so to replace you'd need to cut the manifold open.
I know this a little older but what's the part number on that intake?
sorry I just remember it was Dorman. I think I got it from autozone?
@@southfloridagearheads Ok I can't find a plastic one with a removable pvc I've seen aluminum ones.
you can keep your old manifold if the valve fell out and buy a cruze fix kit. @@keyf1106
I replace the valve cover 3 times on a month and still has oil leaks 😢
where is it leaking?
@@southfloridagearheads
The first 2 times all in the side of the belt side, a lot of oil, after that we change the valve cover for the 3rd time and now it’s leaking only on valve cover
@@andyrenteria4676 hmm? and your putting the little dab of RTV where the timing cover meets the block? what about the torque sequence for the cover?
You don’t think I need to change the intake manifold, maybe that’s the problems of the cover oil leak
It’s looks like I have the same problem as this video 😅, same oil leaks
I got the doorman valve cover and intake manifold still po171 the cruz is utterly ass bottom line
check the vacuum lines under the intake manifold. I had one pop off and caused that code from the wastegate lines.
