Why This Valve Cover Kit Is the ONLY Real Fix
On the GM 1.4L turbo engines, the PCV valve is built INTO the valve cover.
Once it fails (and it will), nothing short of a full valve cover replacement works.
This MITZONE kit fixes:
-
Oil leaks around the valve cover
-
Cracked or warped OEM housing
-
Failed PCV diaphragm
-
High idle & surging
-
Whistling noises
-
Misfires
-
Oil in intake tract
-
Boost pressure leaks
-
Vacuum leak check engine lights
Replacing the gasket alone won’t fix ANY of these. This kit will.

Got this for Chevy Trax 1.4L Turbo, and it fits like OEM. The Trax was getting a couple different CELs, and after some research, turns out it is bad PCV valve built into the valve cover. I had to replace this AND the intake, because the root of the problem seems to be a bad valve in the intake manifold having to do with turbo boost pressures blows out the PCV valve diaphragm. After these were replace, car runs strong again, no more hesitation or excessive oil consumption. Install was pretty easy, with some basic tools it all can be done. I used the the old oil cap, this one looks too generic. It all fits like OE, and looks like OE and there are no leaks. Good product so far.

2014 Chevy Cruze started whistling LOUD at the beginning of last week. At first I thought it was a part of a Rage Against the Machine song I was listening to on the radio (LOL!), but alas, it turns out it was coming from the engine compartment.Engage: YouTube Shade tree Mechanic Mode!A bit of google searching and YouTube browsing later, and I was able to diagnose the issue as a bad PCV valve on my 2014 Chevy Cruze LTZ. I was just brushing up near 96K miles, and apparently all the 1.4 L EcoTec engines produced by GM are destined to blow the PCV valve…not a matter of “if” but WHEN. My PCV valve had apparently had enough, so I found this product and it had great ratings and at a good value. I had heard that dealership wanted ~$100 for parts and another couple hundred (~$300) for labor, so I was determined to save the cash…There are plenty of step-by-step videos online that show you exactly how to make this swap. If you have a decent tool set and any mechanical inclination, you CAN do this. It’s not that hard…I’d give it a 4/10 on difficulty scale. If I was doing it a 2nd time, it would probably take me less than 40 min. 1st time around it took around 1.5 hrs, but I was really taking my time, too.A few notes of importance:-When prying off the old cover, use a PLASTIC putty knife to free up the old seal. If you use a metal putty knife or scraper, you risk damaging the surface, which would of course lead to later oil leakage and nobody wants that.-To give extra leverage getting the old cover off, insert the PLASTIC putty knife as far as you can, and then use a thin flathead screwdriver ON TOP of the putty knife (so you’re putting pressure on the putty knife with the screwdriver and NOT the metal flat mating surface), and gently but firmly pry upwards. That should release the seal and allow you to remove the old cover successfully.-Wipe down the metal mating surface to remove the crankcase oil before seating the new cover & seal. I used isopropyl alcohol and paper towels to get it clean.-Make sure to use Black RTV sealant on the seam of where the crankcase meets the timing belt area. It should be pretty evident where, because there should be the remnants of the old sealant there, which you’ll need to scrape off (with that plastic putty knife!) before applying the new black RTV.-GET YOUR TORQUE CORRECT. The specs for this are 71 INCH LBS (not FT LBS!), which isn’t a ton of pressure – just past hand tight. Don’t guess on this, and definitely don’t over-torque it. IF YOU OVER TORQUE you’re destined for an expensive trip to the mechanic.-Blow out the bolt holes with compressed air to get any oil runoff out of the threaded area. Oil is not compressible, and will result in you over-torqueing the bolts, leading to unequal seal and eventual oil leakage, and that expensive mechanic trip as mentioned above…-If you need to reset the Check-Engine Light, just remove the negative cable from the battery, and go open the drivers door and press the brake pedal for 30 sec. That will drain all the stored electric energy, and reset the CEL. Make sure to follow the instructions on the dash after you start back up…the Chevy Cruze makes you roll down the drivers window and then back up (odd), but that gets everthing back to normal operating condition.

Do NOT buy this!!!PCV valve was defective and caused the motor to smoke badly. Reinstalled it twice just to be sure. Went to the auto parts store bought a Dorman one and boom fixed!!! Now car has a plugged catalytic converter that is gonna cost a thousand bucks to fix!!!! NO THANKS MITZONE!!! YOU STINK!!!

Great valve cover replacement, get the OEM cap and adapter though, the cap included with this will vibrate out and cause a huge oil leak. Perfect fit on the actual valve cover and no leaks yet, was extremely easy to install, and seems to be pretty much the same as the original design. Not sure about durability but it’s a plastic valve cover, if it goes bad again I will invest in one of the aluminum upgrades but for now it looks good and isn’t leaking, I only took the last star because of the horrible cap that ended up coming off while driving. Throw that part away and buy the OE full cap assembly and this valve cover is great for the price.

2018 buick encore 4 cyl turbo. fit good. requires 2 spots of silicon on the engine head, and you should swap the oil fill tube to reuse the OEM oil cap. there is a video on youtube how to do all that. do not forget the 2 spots of silicon where the engine head connects to the timing chain cover. also a note my bolts were ETORX10, the new bolts are ETORX11.
