Alright y’all, I’m here to eat crow & admit my Cruze needed the PCV fix kit!

If you look at my past comments, I was certain the fix kit was just a member of the community trying to profit off us…until I noticed my PCV hose was cracked & leaking putrid odours…

It’s only been a day, but the smell has already dissipated to a shell of what it once was (thankfully).

My MIL has turned off & it doesn’t idle anywhere near as rough after coming off the highway.

Thank you Dre - hopefully my Cruze can make it another 200 000km’s because of your fix kit!

Attached is before & after pictures.

I’ll be preaching to every Cruze owner this kit will save you all the issues if you do it as PM instead of wait for things to go wrong…
I had cam seal leaks, coolant leaks & rough idles (all consistent with PCV failure).

She’s been running like a beauty all weekend & even did oil change today to know everything is fresh!

Thank you for the honest post. I try my best to keep the price down on the kits to make them affordable. In fact, a month and a half ago I spent an entire week migrating my site from to a new ecommerce platform solely to be able to offer more affordable shipping options for international orders. Canada used to be only USPS priority mail for $25 extra, and now I can ship UPS and FedEx for $20 (sometimes less). I haven't increased prices on the V3 kit through all of COVID; it's been $75 for the past 4.5 years running. If there's anything else I can do to help or assist with, please let me know!

You upgraded your PCV, but downgraded your coolant!

Haha as an actual comment, nice work! PCV fix was the first thing I did with my Cruze and I have zero regrets. I'm planning to replace the thermostat at some point soon with a metal one - how tough was it? Did you have to jack the engine up? Did you replace the pump while you were at it?
 
#9 ·
Haha what kind of windshield washer fluid is that?!?

The thermostat was an easier replacement than the outlet.
Probably will need to clean your bolt heads before taking them off.
I jacked up drivers side of the car when doing flush but there was still coolant gushing out when I pulled off the old thermostat.

I did not do the water pump because that is a much harder job than even doing the outlet!

I'll jump on the wagon and concur as well. The kit is a little bit spendy, but don't be fooled, it winds up being cheaper in the end that trying to put it all together yourself. It's totally worth it not having to source parts from 8 different places and make 9 trips to the parts store or Amazon to get all the stuff you forgot or didn't fit. In the end, it's less expensive to just buy the kit. I don't know the guy who makes the kit, but I try to sell it every time I see this subject rear it's head on the forum here, it's a solid fix. Even the instructional video eliminates the typical DIY mistakes one might make during the process... wasting materials, etc. I did my sons car and replaced everything including the valve cover all at the same time and the thing runs like a sewing machine now. The only thing I'll add is that there is another check valve that can go bad that is not included with the kit (GM# 25193343), and mine was bad which required replacement. This must be checked during the install to make sure everything operates as intended. The check valve is on the end of the tube that clips onto the turbocharger housing. You should be able to blow through it in one direction, but not the other way, no air should leak past.
I went all-out when I did mine... removed the intake, scrubbed and cleaned it with soap and water, plugged the hole for the failed factory check valve, replaced the valve cover, the hoses, cleaned the throttle body, everything. All the annoying leaks went away, the car has more power, and now, like I said, the cur runs like brand new again.
I'd also suggest grabbing a handful of extra check valves. They are cheap and it's worth having a coupe around because that will eventually get clogged up and need replaced.

Hey there! I'm the guy who made the kit!

Thanks for the order, and I really appreciate you telling others about it. I try to keep the prices low, but running a business has it costs too as I'm sure you can imagine. I just ordered more boxes today for packaging, for $800, as an example.

The fittings used in the kit however can't be found in store, so you'd be even more frustrated after trying to piece something together to not even find something comparable. The T fitting is custom made (I have my own nylon injection mold made for it), and the check valves have custom internals. The check valves are actually rather special since they have a super low crack pressure and use a genuine viton plunger, which makes them excellent for chemical compatibility and extreme temperature performance. There's a lot more to the kit than meets the eye. Even the PCV hose spec needs to be right or the hose won't hold vacuum or will deteriorate internally due to the liner compatibility.

Thanks again for the feedback. It's people like you that make my efforts worthwhile. I'm grateful.

Is the PCV fix compatible with the ZZP Aluminum Valve Cover?

View attachment 307367

Thank you,
Click to expand...
Yes, technically it's compatible since it has nothing to do with the valve cover, but I generally recommend against all aftermarket valve covers on these cars. There are tons of reported issues on the aluminum valve covers, and they offer zero benefits over nylon in this application. The aluminum ones (from anyone, I'm not targeting ZZP in this) have issues reported such as oil leaking through bolts, valve cover warping, premature failure of the diaphragm, leaking around the edges of the diaphragm, early gasket failure (with no replacements available), diaphragm cap blowing off, oil fill cap blowing off, and other various leaks.

The only thing that matters on these valve covers is the durability of the diaphragm, and in that area, the OEM valve cover is best. You can usually get 60,000-120,000 miles (sometimes more) out of an OEM valve cover with a good working manifold or my PCV fix kit installed. That's why I offer the OEM valve covers on the cruzekits site instead of just reselling the aluminum ones. I could make a bigger profit on valve covers if I resold the aluminum ones. They're only $36 on alibaba... Aluminum Camshaft Engine Valve Cover For Chevy Cruze Sonic Buick 1.4l 25198498,25198874,55573746 - Buy 25198498,Cam Cover,Cam Rocker Cover Product on Alibaba.com

Remember Cruze 1.4 turbo does not use an oil catcher stock valve cover does this Will the aftermarket covers work as well ? Putting in an oil catch can too? My cruze with 120k looked like like the OEM cover. Only the PCV valve diaphragm was bad , and failure was from the 1 way valve that got sucked away into the intake manifold. At 150k no issues with the PCV valve bypass kit nor any of the OEM cover, 1 way valve on turbo.

May I bump this thread?
I plan on ordering the 3.4 kit this week and install it as soon as I can.
Is it really worth it? ( honestly I have to ask)
Which kit is the best to get?
Do I have to remove the intake manifold to install the plug?
And will this help with the MAF sensor code as well?
My son is driving "my" 2014 LT 1.4, He is in college 90 miles away, I just want this done Right and 1 time! Lol a little nervous about a modification deviating from the manufacturer.
You have to understand, I am an Aircraft Mechanic, if we deviate it's on the news.
Thanks for any answers anybody can provide

Get the newest kit, you won't regret it.

Yes, it is worth it. you could probably save 15 bucks if you sourced all the parts yourself, but it would cost you more in shipping and hours of hunting... so don't bother, just get the kit.

You don't "have to" remove the intake, but I did so I could scrub it out with soap and water, totally de-grease it inside. I wanted to make sure the plug never comes out, ever. I like fixing things once and done... rework totally torques me off. I washed it in the garage slop sink (I assume you already know to remove the throttle body and other parts first, you should only submerge the stripped plastic intake) with plenty of dish soap, then did the plug job while it was out. you may want to get some round "pipe cleaner" type brushes of various sizes if you take it off to wash it like I did. I tend to overkill things though, you may not want to go this far, but the intake really isn't difficult at all to remove. another note: if you remove the intake, you will be removing the tiny little bypass pipe from it. Be very careful removing that from the intake side. The intake barb that it plugs onto is very tiny and fragile. Take your time, it will snap off quite easily if you start yanking on it like a gorilla.

this does't fix any MAF related errors.

This kit basically replaces a poor design that is prone to early malfunction and failure, so just consider it an air road worthiness directive. the "design" is the same as was originally manufactured, just relocating the valves and replacing with more durable ones.

I would also suggest ordering a couple extra check valves (with the kit when you order it) to keep in the glove box. the one I installed on my sons car is going strong a couple of years later, but it is just a plastic check valve, and it will eventually clog or jam up one day. they are cheap enough to just grab them now so in the case you need them later you won't have to go on a treasure hunt.
Also, I suggest replacing the valve cover with a GM original at the same time you do this, or at least check the diaphragm on your existing one and make sure it is working properly. they often get popped when the PCV isn't working right, so there is a chance yours is already blown out. check it.

also make sure to test the check valve for the pipe that clips onto the turbocharger end. I am attaching a photo, the circled part is where the check valve is located. You will be cutting this piece off and re-using it with the kit. when we did ours, this check valve was trashed from running for so long with a malfunctioning PCV system, so I had to amazon-order a new pipe so I could get a good check valve. I'll also include a link to the amazon part I am referring to in the case you need one. The valve is easy to check, simple one-way. air should freely flow one direction and slam shut tight not allowing air to go the other direction.

put mine in a year ago . Going strong…. Is it worth it??? YES !!!! You’re taking a rubber check valve out of a high suction/ vacuum area that is inside the intake manifold. It is not if, but when… ( gm what were you thinking ) and moving it outside the motor. Easy access. Super simple. I did not remove my intake. I recommend getting the tools. The cleaning brush was excellent. Used throttle body cleaner. So much sludge//// attache the plug to the screwdriver and…. Take a couple of trial runs before attaching the plug to the screwdriver, making sure you know where the hole is! feeling for the hole, or you will drop it in … read a few have and no harm…. Plastic chewed up a spited out I guess…also recommend spending the extra 50-60 bucks, and replace the other 1 way valve at the back of the turbo, and the pcv pressure regulator. Again way to go GM… glued to your valve cover… none of this is hard just time consuming… and if you replace the valve cover just search this site for step by step, yes you definitely want a torque wrench and follow the tightening sequence. Kit includes everything hose from the turbo… T’s and great online videos….. now comes my next headache the Cruze 1.4 EVAP canister… with 150k OEM canister valve is not working right/stuck here I go again…. What where they thinking…. Attached to the top side of the tank…watched video partially dropping the tank and getting out was a pain… guesss gm feela if that goes so does the fuel pump…. Dealing with exhaust tubing… fun fun fun

I'm another that has suffered the PCV issue. While I would have purchased Andrei's V3.4 kit, I was hamstrung by time and the need for the car ASAP, which was very frustrating in the end. As an aircraft mechanic with car OCD, I have the manuals and usually the time to do my own work.

This next bit is mostly applicable to the Australian market however, it may also be applicable in the US.
If you look at the prices on Cruzekits, you will see that this fix extremely cost effective and an easy solution, thanks to Andrei's efforts.
In Australia, dealerships are unable to just order the manifold and transfer the serviceable components from the old manifold. The intake manifold in Australia is sold complete with a throttle body, fuel rail, injectors and the emissions solenoid valve. The total cost to replace your PCV valve is $2200AUD + labour. :mad:
So my advice is get in early and get one of Andrei's kits!! Even with the cost of shipping downunder and your own time to install the system, you will financially better off. Not to mention the longevity of the kit.

I took a couple of pictures of my old manifold and sectioned the rear side to capture an image of the poorly designed and cheap valve, that just cost me a small fortune.

So for those that come across this article, get on to Cruzekits and read their information. If you have basic hand skills and the time, it may save you an argument about the car repair cost with your wife or partner. (y)

Cheers,
Mark

Thank You Mark!
I am an Aircraft mechanic as well, and have worked on all of my vehicles for over 40 years(yes, I am getting old!)
I have a 1995 s10, a 2002 Silverado, and my wife's 2020 pathfinder.
The 2014 cruze was mine but I gave it to my youngest son after he complained too much about the S10.
(A/C stopped working).H
I am now swapping in a LS 5.3liter V8. So that will be fun!
Anyway, I have the Kit from cruzekits.com, just waiting for my son to bring the car home for a few days so I can install it.(He us in college 90 miles from us)
I might even but a new intake manifold just for good measure because OCD!
Dorman sells the bare manifold, but I like to get acdelco or OEM parts as much as possible. Rockauto.com is a great place for that.
Thanks for piping in!
Sorry it cost you so much$.

I believe you may have called me to discuss this, but for anyone reading this in the future, GM didn't change the design on this. You may have difficulty removing it since it hasn't degraded to the point where some of them have yet, but you can quite easily remove it by giving it a whack with the palm of your hand with a flathead screwdriver. People do this quite often on brand new OEM manifolds when they install my kit, and I believe both BNR and Super Cruzes offer ported manifolds with my kit preinstalled that have this already done.

Ok Gang, need some help, installing the V3.4+ kit as I am typing this.
As stated in my last post, my intake manifold was replaced some years ago when the car was fairly new. Did GM change the Intake manifold to include a better plug?
I am having trouble removing the old one.
Anybody run into this?
Thank You

Good evening I just installed the 3.4 PCV fix kit this morning. Last year I replaced the intake manifold due to missing check valve. Because it was new I had to push the intake manifold check valve out. Should I remove the intake and try and remove that check valve? Not sure if that will damage anything or where it will go if left in the intake.

**** so Dave has claimed another victim I see. That kit will last u maybe 6 mths before it's full of oil again. The kits are just a band aid and hints, u get what u pay for. Here's what u need to do as I built my Cruze into a 450whp monster from frame up. First thing I did was get rid of the pcv system and bypass it using ZZPERFORMANCES 299$ PCV BYPASS KIT! IT ELIMINATES ANY NEED FOR PCV SYSTEM. ZZPERFORMANCE ALSO PROVIDES SOME KILLER ASS CATCH CANS W THERE LOGO ON IT. HOSES AND BRACKETS 1ND ALL HARDWARE NEEDED IS INCLUDED. THIS WILL FIX THE PCV ISSUES THESE CARS ARE FAMOUS FOR Having!!! SEE DAVE CANT OFFER THIS CAUSE ZZP PATENTS ALL TJERE STUFF CAUSE DAVE HAS STOLEN DESIGNS FROM A BUNCH OF PEOPLE AND HES A FRAUD. HES IN THE MILITARY. HE ONLY HAS A URL SO HE CAN GET BIZ LOANS AS YOU MUST Have A ACTIVE WEBSITE.

BELOW ARE JUST A FEW OF MY OWN DESIGNS.AS WELL AS SHOWING U HAVE A TUNING CHIP AND A DATA LOGGER ON A DONGLE IN MY OBD2 PORT SO.I CAN LOG AND SAVE DATA. PAKE HITS ETC ETC. DEF BUY A CHIP.TY3N BUY THE BULLDOG DEAL I SENT YOU. IF YOU NEED ANY PARTS FOR A 1'4l LUJ Cruze then I got best performance upgrades for the best prices! I HAVE CUSTOM FABBED EXHAUST KITS U ORDER AND LITERALLY U CAN INSTALL IN 15MIN W METAL EXHAUST CLAMPS PROVIDED AS WELL AS PIPING IN TWO FOOT INCREMENTS TO MAKE IT EASY TO HANDLE AND FOR HALF THE PRICE AS COMPETITORS.

SO YOU DEFINITELY NEED TO CONTACT ME @ landers454545@gmail.com or by cell at 7065598935

That's odd, because the Cruze kit fix that I installed on my sons car has been there for about 4 years now and functions perfectly to this day.

Edit: Typo... I meant 2 years, not 4. Regardless, the point is the same. The kit works, it's affordable, and it solves the problem
