I noticed the valve seals (O-rings) for Driver side are bigger than the Psngr side. If taken out, you can easily get confused and mix up a incorrect seal install causing a future oil pool leak around the spark plug. The bigger seals have 4 small dots behind around the ring.

Did you guy use oem bolts to secure the mitzone valve cover down to the head? Or it’s mandatory to use the supplied bolts that came with mitzone valve covers?
The new valve covers are identical to factory so your adaptor should still bolt in. It looks like they copied the original and made a mold for cast aluminum.
mmh not shure if i missed it but i have a pair of czp valve covers and now i need to put them on. maybe i missed it but why did you go from czp valve covers to the red ones which are basically the same?
After installing this over a month ago it started smelling like burnt plastic. Could it be from the plastic that you have to loctite the screws? Will the smell go away at some point?
24 hours. You can put rtv on the corners of the cylinder head and let it sit for a few minutes. This car we didn't, but it hasn't had any leaks. And right now we travels 500-800KM per week.
@@AnthonyJ350 thank you for the reply. Wow 24 hours befor install? I was thinking 5 mins then install lol. I think I'm gunna wait 5 mins then install and wait a full 24hours befor fire up
@@AnthonyJ350 just got mine today and both pcv holes on the driver side cover are blocked and will require drilling out. And the plastic baffles are not great some damage from the screws. Did you inspect the pcv holes to make sure none were blocked ?
Serious question how important is the torque wrench on the valve covers? Cause I rly wanna do this to my g cause mine are leaking bad and I just got a cd009 transmission put in it don’t want engine problems now
How's it going @AnthonyJ350?! By any chance can you elaborate if you used any gasket markers when seating the valve covers onto the heads. My worry is that over time the gasket will become brittle and bypass oil from this area if not sealed with a secondary support.
@@yiannismcguire9118 We only used gasket maker to hold the gasket to the cover during installation. You can add gasket maker to the corners to help it seal more.
Hey, I want to replace my Valve Covers. Are the Concept Z products really that much better than Amazon? The valve covers I have on now are probably 3 years old and I'm seeing leaks in the front passenger and rear drivers. These were Amazon plastic style with the brass wire mounting inserts and the last time I worked on my car, i pulled one of those inserts out. It just has me questioning an upgrade. What is your experience with heat problems or anything I should know? 2003 G35 Coupe 6MT and I've replaced so much stuff already. I do like the idea of changing the spark plug tube seals.
Hey Anthony love your videos! I also bought these and did them maybe about 3-4 months back. I checked everything also did loctite on all the bolts on the inside, I'd watch the spark plug tubes makes sure they don't leak. Mine recently started, I'm wondering if it is just cheap seals, I'll probably end up taking them off and replacing the spark plug seals soon. I know Nissan makes OEM replacement spark plug seals, I think one of the Infiniti's with the same engine had aluminum valve covers where you can replace all the seals. I'll probably end up getting those seals.
@@AnthonyJ350 Thats a smart idea, I bet just a little bit of motor oil would help too. also did you ever figure out what that clanking sound was? was it the main tensioner for the timing chain?
Can anybody tell me how well these amazon ones hold up in the long term? I do atleast an hour of highway driving for work and sometimes a couple of pulls😅
Following this video, I will step up the VC set a bit further. 1: Powder Coating it for a harder shell color layer. 2: Ishino Stone Japan gaskets & oem pcv 3: Replacing ALL aluminum bolts w steel ones or bttr. 4. Extra sealant on the corners of the valves, where its notorious for leaking at. TIP: If you still see white smoke or smell it inside the cabin. Check the lower exhaust manifolds (Headers) and wipe off any past oil residue around them since it gets hot and probably burning up the old oil leak problem you just solved.

Very good instruction on installation. Did you put sealant on the sharp bends like the factory does? I have been told if you don't, you will probably experience oil leaks around that area.

The new valve covers are identical to factory so your adaptor should still bolt in. It looks like they copied the original and made a mold for cast aluminum.
I just purchased the aluminum version from Miliparts. The paint well I was impressed with the quality. Is the PVC removable?
PVC is replaceable
@AnthonyJ350 I tried using a wrench, but all I managed to do was scuff the corners. I need to use a shallow socket.
Have you done a temperature difference between these and OEM?
No, I assume they would contain more heat being aluminum. I had mine powder coated.
is that all thats needed is what comes with the kit in your link? also how long of a job overall was it?
Yup. Took us 6 hours (we were also filming).
mmh not shure if i missed it but i have a pair of czp valve covers and now i need to put them on. maybe i missed it but why did you go from czp valve covers to the red ones which are basically the same?
This is Raul's car and he purchased the Mitzone, I have a set from CZP that I still need to have powder coated.
Did your OEM pcv valve fit fine? I tried reusing mine and it won’t thread in right
It should. It didn't come with a new one?
Is threadlocker blue enough for the fasteners? Was thinking about using red because I don't want any of them eventually becoming loose.
You might not be able to take them out after.
@@AnthonyJ350 Would you recommend sticking with blue?
@@koi124 Yes I would. Let it set overnight before running the engine

It still smell like burnt plastic? Check your wiring and make sure it's ot resting on something hot.
Did you ever get this figured out?
So rtv only on the cover side in the corners? No rtv on the engine side surface? How long did you let the rtv set befor installing the covers ?

Very important
Do you know if these fit an vq35HR , I’ve been only seeing DE ones , idk if it matters or not
I think it's only available for DE applications at the moment.
I see you switched the pcv valve, is it necessary or does the one that it comes with work?
The one it comes with should be fine. The PCV was recently changed on this car so we decided to reuse it.
Best to use a oem pcv or one from Autozone. The one it came are reallllly cheap and will smoke.
How’s the valve cover working for you ? Did you keep their gaskets or got another pair ? I heard they have iffy gaskets
We used the provided gaskets. Raul said they've been fine so far.
Get the oem Nissan or Ishino Stone gaskets...
Anybody know the nissan part number for the spark plug seals? Or the yr model of the car that uses the oem seals? Thanks in advance!
There's a left and a right side. Concept Z has them on their website.
