- Is your Cruze (Sonic, Trax, Buick, Vauxhall Astra, whatever. Anything that has the 1.4L Ecotec engine) constantly throwing any one (or combination) of these codes: P0171, P0106, P0299, P0507, P1101 or P2096? Well, congrats. Your PCV in the intake is probably junk. It happens to all of them at some point in time.
Symptoms of a bad PCV system are any of the aforementioned codes, poor performance, poor mileage, too high crankcase pressure that leads to blown out seals and leaky oil pan gaskets.
The PCV design is known to be faulty with this engine and causes tons of problems of various severity. Luckily, there are people that make kits to alleviate the poor design of the PCV, so you don't have to worry about it again. (You can also make your own if you want to piece everything together.)
In this video I show you how to install the CruzeKits PCV kit as well as adding on the SuperCruzes catch can. I show you the layout for the routing both with and without the catch can so you can decide what route you want to go.
Yes is said PVC many, many times in the video. You know I meant PCV.
I also said 1 bar for crankcase pressure. I meant 1 psi. One bar (14.5 psi) would be way too high.

Thanks for watching.
Thank you, you're the only guide that actually goes through everything when you're using the catch can. Not even Dave went through it like you did.
No problem. I try to make things as easy as possible for someone watching so they can get the job done and not have to worry about trying to track more information down.
@@greasyfingergarageHey I have two questions tho, how did u tighten the holder for the catch can because my hands cannot secure that damn bolt and r the hoses connected to the catch can supposed to be tightened or secured at all
@@bruhbro I used duct tape to hold the bolt in the bracket and the bracket to the car. Put the nut on bolt in the fender well and used a gear wrench to tighten it up. The hoses to the can are held on with hose clamps.
@@greasyfingergarage thank u so much man
Friend, I placed the oil trap wrong, the line that comes out of the gases goes directly to the oil collector, then it comes out without clean oil and there is the t connection to the PCV and turbo.
i had the failure happen, saved me thousand dollars literally.. been 20k miles and still going good. best fix ever, no need to replace the entire intake!
Not to mention that if you "fixed" it per the way a dealership would, it would just break again since they replace it with the same garbage parts.
I am in the UK, just ordered the kit from these guys👍
Awesome. Hopefully the shipping wasn't too bad.
just did this and luckily I had already ordered a new PCV Hose for this car months earlier. Lucky I did because the valve in the bottom part.( near the turbo) eas completely gone. When you take that hose off if you can blow air from that bottom part then the valve is missing. On the new one when you look in that bottom part of that hose connector, you can clearly see the orange valve. You can actually suck through but you shouldn’t be able to blow through it.
I simply took the new PCV hose. I got and cut the ends of it off to use instead of the old one. Not expensive at all on eBay or wherever anyways, I think this is something important people should know. If you did it without replacing the bottom part of that hose then you are probably missing that valve also. Should be easily remedied and replaced.
I don't think the valve being in the hose you are replacing matters when you do this. Those are replaced by the external check valve in the kit. Just replacing the PCV hose itself can sometimes fix the issues since that is leaking pressure back. But they just end up blowing again at some point. The purpose of the kit is to replace the PCV system with something that doesn't suck.
I didn’t notice you saying PVC instead of PCV. I got beer in my ear 👂!
Great explanation of how the pcv system works. My question is, why bother even rerouting the crankcase waste to the turbo at all? Any intake system should have clean air and clean fuel. Why introduce crankcase garbage? Why not plug the dump fittings entering the turbo and run that hose down under the car, or to the inlet of the catch can?
Emissions and the fact that it is a closed-loop system. Back when everything was carbureted, you would just stick a breather in the valve cover that would vent the pressure to atmosphere and call it done. In an effort to help lower emissions, the excess pressure was then directed back to the intake tract to help burn off any remaining hydrocarbons that has slipped past the rings into the crankcase and then be directed out through the cat.
When OBD1 came along, the PCV system was nothing more than a check valve in the valve cover with a hose that tied back into the intake at some point. That was pretty much it and the computer didn't monitor it at all. When everything switched over to OBD2, there were sensors added for everything and the computer would start live monitoring every system of the car.
The PCV system was then considered closed-loop and the airflow coming through that system was accounted for and programmed to be within a prescribed threshold limit to be functioning correctly. So being that it is a closed-loop, if you were to just dumb the crankcase pressure out without running it back through the system, the computer would read as your car having a massive leak and throw a myriad of codes. To do something as you are asking about would require reprogramming the computer to completely eliminate the PCV system.
Modern cars are a tradeoff between maximum efficiency and maximum performance. When it comes to the PCV system, they actually do help with emissions (even if a little dirty air makes it back around to be burned again) a bit as evidenced by the fact that they are still around. Unlike the power-robbing, weight-adding Smog/AIR pumps from the 70s and 80s that existed solely to pump fresh air into the exhaust to make emissions at the tailpipe read lower instead of actually doing anything.
@@greasyfingergarage . Thanks very much. I appreciate the detailed explanation.
The only reason I can think of is emissions clean air act.
@@greasyfingergarage I hate failing smogs over the useless AIR system being missing. Like you said, it just tricks the probe, doesn’t actually help emissions.
@@jakegenocide Most states don't even bother checking for them or doing those sorts of emissions tests on vintage vehicles anymore. And That is a good thing.
I put a upgraded doorman intake on 200,000 ago runs strong 44 mpg no leaks took 25 minutes was only 95.00 bucks
I've heard mixed things about those. As long as its working for you that's what matters.
I have a catch can for my 2000 Toyota with 210K. I can see the oil mist from the PCV hose in the headlights. I don’t want it to turn into carbon buildup.

The ZZP one is supposed to be even more efficient,do you know if that’s legit?
What do you mean by more efficient? I personally have zero experience with the ZZP kit so I can't speak for much that goes into it. I do believe that their kit is only offered with the catch can and the price is the same as doing the combo kit that I did. I think they both use the same catch can. The ZZP kit is definitely more "professional" looking with the mounting brackets and molded hoses. I do believe that you have to pull the intake off for the ZZP kit to add some sort of spacer (don't quote me on that). If that is the case though, you could just go with the updated GM intake that supposedly fixes the PCV issue (I have no experience with that intake either). In the end, it is multiple options that address the issue in different ways. I just chose to go this route, and it is the only thing I can speak from experience on.
I’ve replaced my valve cover and all and my Chevy Cruze idle is kinda funny when I come to a stop the car still wants to move like it will jump any suggestions??
Sounds like you are describing the engine surging. That is usually caused by air getting sucked in someplace other than just the intake. If you have any codes, see what they are saying. I don't know what all you took off to change the valve cover but you may have not put everything back on exactly correct. My default assumption though would be that it is related to the PCV in general. You can pull the hose off the intake and look in to see if you see the nipple in the intake. Even if it is there it doesn't mean that it is functioning correctly though. I would recommend doing at least the PCV fix kit. You don't need to do the catch can unless you want to do it as well.
Purge valve 39 bucks throws a body code
Why would your Chek engin light comes on in my cruze?
I am assuming you are asking why your car would throw a check engine light. There are tons of different reasons that your car could have one. If the light is on, you need to get the codes scanned. Then you can start the process of narrowing down what it is causing it to throw the light.
Thanks for the feedback. I really want to do this kit and fix problem ahead before it causes problems. Everything looks straight forward except putting the epoxy with adhesive and cap. I really get confused and wouldn't know what I would be looking for. Does the kit come with instructions on how to take off original and cap it off with new kit? Thanks again
I thought I did a fairly decent job explaining it. At 9:50 in the video I take a pic and just poke at the orange nipple in the intake until it breaks up and I can push the pic through the hole without resistance. I then use a shop vac to suck all the pieces up in there. Anything that is on the other side of the wall where the rest of the PCV is will just get burned up in the engine. (This happens all the time on their own when they fail). At 26:00 I go through the process of putting the plug in. You can also look up the install video made by the PCV fix kit guy himself if you want some more info as well.
Sorry if I missed it in the video but is the catch can really needed? What benefit does it add? I was going to do just the pcv fix kit.
While every car runs, it has water vapor, air and oil mixing together, forming a funky orangish sludge. How much is produced depends on a lot of different factors. The catch can separates that sludge from the air being fed back into the intake to be reburned. Does a car need a catch can to run? No. I can't think of a single car that comes with one from the factory (mostly because it would just be something else that the owner would have to keep track of). They definitely have their benefits though. You just have to decide if the added cost of a catch can is worth it for doing the fix. But you can do just the fix kit and it will take care of the PCV issues.
@@greasyfingergarage Good to know thank you
I have a coffee can 😂
I have a 2013 base model 1.8 L non-turbo.. just change the coils and spark plugs and valve cover gasket because it was leaking causing skipping while I had the valve cover off I cleaned it PCV valve openings with the valve cover off mates for everything was drained wiped cleaned reinstalled valve cover new gaskets Etc stock car up no more skipping so the coil pack and spark plugs and Etc take care of that but somehow I ruined my PCV valve hissing and making noises out of the valve cover of course similar car but different engine on Turbo instead of buying a new valve cover with the new PCV valve set up in the cover can I just disconnect what's there and put a catch can where am I going to need that vacuum leak fixed
I have no experience with the 1.8, so I am probably not the best person to answer this question. I do believe the PCVs are far better in the 1.8 than the 1.4 and can be replaced independently since they aren't a part of the intake like the 1.4. I also do not know if the 1.8 is overpressurized like the 1.4 due to the turbo and terrible PCV design. If you were wanting to add a catch can, I would imagine that it could be put inline of wherever the PCV hose runs, as long as it isn't affecting the flow around the EVAP system. You will still need to have some sort of PCV valve in the loop though. Your best bet would be to look and see if Supercruzes or ZZP offers a catch can kit for the 1.8 and see how it works. You could also probably ask them the question directly. They would be more knowledgeable about it than I.
Can you tell me what was the mileage on the Cruze when you did this job? I have a 2014 Chevy Cruze Lt with turbo and mileage is at 86 thousand. Thanks for the video any feedback appreciated
I'm a bit over 120k. It can be done at any mileage since the problems pop up fairly early from the terrible design of the PCV system.
I've replaced the valve cover, intake and throttle body a couple of weeks ago. I have everything needed to do this setup except for the clip that you epoxy for the pcv inside the intake. Do you have to do this process since I've put a new intake on? If so do you have a part number just for that small clip or where to buy?
Since you already replaced the intake, you do not need to do this. The intake will have a new PCV diaphragm in it that will work, for a given time. How long it lasts is yet to be determined. I would just run it the way it is now until it starts throwing any of the codes that can be caused by the PCV issue (it will fall eventually since the design is still the same).
As far as that little insertable button clip thing that comes in it, it just comes with the kit. No idea what the name of it would be or if there were some sort of part number. I would imagine it was chosen because it fits in the tube while the intake is still in the car. You could reach out to the cruzekits guy and ask him. Maybe he can just send you one.
When you had the new intake out before you installed it, you could have popped out that diaphragm and ran a screw into the hole and epoxied the rest of the small ones shut.
I would just run it like it is for now until the issues arise. Just understand that they will happen again at some point.
The new intake will eventually do the same thing as the old one. The “ plug “ from this kit replaces and fixes that inadequate and flimsy rubber??? nipple thing.
9:21 plz i need buy this plastic . i lost what is the reference. code
I don't know what the name of that piece is or if it is available individually. I looked up exploded diagram views of the PCV system and it shows everything in that hose to be one unit. You may have to call the parts department of a dealership and ask them to see if their system shows it. If not, you would have to get the entire hose and cut the connector out of that. Maybe you have gotten lucky though and the piece isn't missing but is actually stuck up inside the elbow. If it is extra dirty, it could be there without you being able to see it.
My Chevy Cruze just makes a clicking noise when starting
My negative battery cable is brand new and my battery is good
What do you think it is?
Are you positive your battery is good? Clicking when trying to start is usually a dead giveaway of a junk battery. Keep in mind that even if you check the voltage of the battery it can show up having a full 12volts when it has a dead cell inside. Make sure the battery is fully charged and take it to get a load test at any auto parts store. Another sign its the battery is if you are able to start the car by jumping it.
Clicking could also be the starter solenoid I think? Key or push button start? Try turning the key just until the on position and right back again two or three times. Not dur3 how you would do that width pudgy button start.
Question, what if I already have the pcv fix, how do I only get the catch can?
You can get that from Supercruzes. It is the first option from the dropdown for the PCV fix kits. It comes with the can, bracket and hose kit to integrate it into the kit you already have. You can always call them up to be sure though.
I just did this to my 1.4T junk and it is still making way to much crankcase pressure. Why!?!?!?? Why is that.
Piss poor engineering from the get-go. That's why they have all the problems. As far as why your car still has too much pressure, who knows. Did you clean out the PCV port enough when you did the install? If you did this exact kit, is the check valve aligned in the correct direction? I'm also 100% convinced that these cars throw codes for problems that don't actually exist. Its pretty obnoxious.
Two things to check. Take that PCV fitting off of where you put in the plug. Maybe the plug and JB Weld didn’t completely cover the centre hole where the orange nipple was or it wasn’t cleaned and dried enough before you installed it. Also after installing the plug did you leave the hole unplugged for at least 15 hours before reattaching the fitting over the hole? If you put everything together and start the car up right away the JB Weld could be blown out of the holes. One other thing it might be is that the Purge Valve in the back may have already been faulty which will throw those codes too. Get a new purge valve and redo that part of the kit. Lastly, did you remove the intake “ beauty cover “ and check that diaphragm on the valve cover? If it makes a “ clicking sound “ with the engine idling or if a piece of Kleenex gets sucked or pushed away from that diaphragm then that part may have already been destroyed.
Quick question could you run a pcv valve out of the valve cover to the intake manifold and T a line to the turbo
The PCV out of the valve cover to the intake is how the system used to work on OBD1 cars. I do not know if doing that exact layout would work on a forced induction system. You would also need to modify the valve cover for a tie-in in some way. So you would have to pull the cover off to drill and tap something into it without getting plastic in the head. You also won't be able to tie directly into the current plastic line that runs from the intake to the turbo. It will just disintegrate on you. ZZperformace offers a kit that runs out of a new oil fill cap to the turbo, then new lines to a spacer that goes between the intake and the head.
So a long answer to your quick question. But I truly don't know if that layout would work. My assumption would be no and you would still be throwing codes.
@greasyfingergarage just something I thought about watching your video it can't be that complicated
@@levialston518 The biggest issue is making a solution that works without tripping any of the obnoxious and unneeded sensors so the car stops throwing codes. More computer controls means more things that can cause problems with said controls.
I got Holden Trax
Just looked up a pic. Seems like it is the equivalent of a Sonic.
Isn't this a class action lawsuit? Chevy knows this is a problem there just making money off all the labor and parts after the nipple blows
No clue. I do know that there were clearly enough issues that GM would start covering the valve cover fixes and refund stuff that was already done, to an extent. They wouldn't refund the money for the crank seal failing due to it. Or the oil pan gasket getting blown out.
If it is a class action lawsuit, it means nothing. The only people that benefit from those are the lawyers. They get 98% of the money and everyone else comes away with like $2.37.
I have a question
Which is?
That was the question 😂
So sorry guy.
I just can't get past spending $270 on a item that i have to use super glue on.
Do the painties come with it ? ...@ 9:38 😆😆😆
Then don't do it. I don't care.
PVC? You must be a plumber?
I'm a plumber in that I lay the pipe. Haha. Ha. h.... I'll see myself out.
@@greasyfingergarage 👍I’ll stick with the ABS pipe. Plumbing is alphabet soup
The guy who makes the pcv kits has found that there’s no benefit to a catch can on the gen 1 Cruzes.
There are several people that make PCV kits. I just elected to go with this one. If there were no benefit to a catch can on a vehicle, the can would stay forever empty. But even if there is any sort of liquid that accumulates in it, then there is a benefit since it is keeping that liquid from recirculating back into your engine. Whether cost/benefit ratio is to someone's liking is up to them to decide.
There are other vehicles that get that yellowish sludge in the oil and can often be seen under the oil fill cap. In really bad cases the oil pan can become caked in that sludge. Just think of it a a “ what if it happens safety net. Even I lifejacket isn’t needed if you don’t fall into the water.
An when it burn off in the cylinder it causes detonation an knock
I would take the safety measure of what if with a catch can than not having anything
Used in vauxhall astra in uk too
That's good info to know for all the Europeans out there. I'm sure it may be used in more vehicles under the GM umbrella like Holdens, but I can't keep track of every car the engine is in the states let alone everywhere else. Our coolest cars for several years here were just rebadged Holdens. It is the GM way.
Shared video on astra j forum for u thanks for video
@@grimreaperbadboy Well I certainly appreciate that.
q desmadre eso
Not sure what you are saying. Hopefully good things.
What crazy fool would spend $270 on cheap hardware? 😂
What crazy fool would choose to live in California?
You could had cut this into a 10 min video and it would be a lot more informative and helpful
I'll be sure to reach out for approval next time.
