This is the most THOROUGH video on this topic I have found ! Awesome video sir, you did a great job ! 👊👍
Glad the video helped, any questions just ask! Thank you for watching and supporting my channel!
glad to see the level of detail in this but you wouldn't be this meticulous in a garage the boss would go crazy
nice job though good to see you care just wish the industry respected this style of work instead of clock watching
you probably dont care but if you guys are stoned like me during the covid times you can stream pretty much all of the latest movies and series on InstaFlixxer. Been binge watching with my girlfriend for the last days =)
@Ramon Jaxx Definitely, been watching on Instaflixxer for years myself :)
Beautiful job & explanation - will be digging into ours as soon as we get the parts. Thank you so much for taking the time to make this video.
Check out my newest video, 350z valve cover gasket replacement, the ultimate guide!th-cam.com/video/_15ivIVS9_I/w-d-xo.html
DAMN! That was a great video! I've got oil in my number 6 spark plug well and I'm going to replace the valve cover gasket also. Thanks for all the camera work and editing.
Thanks so much for your support!!
Thank you so much for making this video. This job just got added to the to-do list on my Z and this video is perfect
Great video, I like the clear explanation and transitions are smooth. After watching this video, I feel like I can do some mechanical work!!!!
Very knowledgeable on Zs, learned a lot, ready to go do it myself, thank you very much sir
Wow, best video I've ever seen on maintenance for the Z
Thank you so much for watching!!!!
Its been about one year and everything is still good thank you Z-SPEED , just a note to others please use OEM valve covers which you can get at Z-1 Motorsports and else where don't be cheap buying aftermarket they will leak
Hi Z Speed, just bopping over to do a lil catching up with you since my last visit. *LIKE* *10* here. Gret to have this gasket replacement so lovingly explained in intricate detail for someone to really learn how to do this. From the #IAmACreator grassroots community. Cheers and blessings, April
Thanks for clarifying about the spark plug tube seals that cannot be replaced. I was going to buy just the gaskets and and spark plug tube seals but now that I know they can't be replaced, it will save me the headache.
Thank you for the detailed process. Great video!
Thanks for watching my video, a valve cover job is something you only want to do once!!!!👍
@@Zspeed Yes indeed. I was able to get it done with the help of your video. Had a really hard time with passenger side cover as the gasket kept falling off and fuel line was in the way. Had to apply quite a bit of sealant to hold gasket in place after the third attempt.
6.5 hrs later, victory!
I'm so glad the video helped, I was thinking about releasing a 2nd video on the valve cover job, I have a lot of footage that I had to cut out. Do you think an even more comprehensive video would help or is this one good enough?👍
Great video. Love how you went into detail. Thank you.
Thank you so much for watching!!!!!
Video was really helpful finally I found one that answered all my question. Most videos out there couldn’t really see what was going on and couldn’t really understand. Trying to change my valve covers soon Both are leaking. Thanks for the video 👍🏼
Thank you so much for watching!!
Z-speed how did you remove the clips holding the bar on the driver side I’m having trouble with it
Are you talking about the clips on the strut tower brace? If so you can use a small pair of needle nose pliers and try to detach them that way!
Great video man. I feel confident enough to tackle my Z now. 5 star video man. Good tunes too.
Give yourself at least two days so you can take your time! If you have any questions just ask and I will get back to you A.S.A.P.!!!
@@Zspeed thanks alot. I will.
Best video on this subject. Thanks a ton!
Thank you so much for watching, check out my new updated video: the ultimate valve cover replacement guide!!!
Very detailed video, thank you some much for sharing!!!!!
Thanks for watching!!!!👍
Excellent Job! Thanks very much!
well done, sir! thank you for this.
So glad it helped!!!!Thanks for watching!
Just a suggestion. When removing the strut tower brace, you should loosen the jam nuts on the bar first and remove the tension on the bar, then when replacing after you bolt it back on, you would re-tension the bar. Great video though. Good stuff.
Your 100% right, I finally realized that little trick after removing it 3 or 4 more times. Thanks for watching, I also have a updated version of that video: The ultimate 350z value cover replacement guide!

I have a updated 350z valve cover replacement video, let me Know what you think: th-cam.com/video/_15ivIVS9_I/w-d-xo.html
Thank you awesome vid
Glad you enjoyed it
AWESOME Video!! Still scared to do this to mine though...lol
Question: My Z has 231K miles on it. I love the car but it's now starting to give me some engine issues. Is it worth fixing? I would love it to last another 200k miles. One issue is this cover project.
If you do the repairs yourself, it shouldn't cost to much to bring your Z back to life!!
FYI... Anytime you need a gasket or washer on a bolt to stick in place temporarily use super glue...It dries quick and it's thin and will not interfere with sealing afterwards
Great idea, I've never tried superglue!
Great Video! I am in the middle of it right now. I am trying to get the wiring harness free, but there is one wire toward the front of the car that comes off the harness(by the intake) and goes down deep to a plug that I cannot get to on the drivers side. Pain. Tomorrow I think I will jack the car up and see if I can get to it from below. That one wire, has prevented me from getting the harness out of the way so far. Good stopping point for the day. The rest of the project has gone pretty smoothly.
Thank you so much for watching, if I come up with any information about that wire I will surely let you know!!!
@@ZspeedFigured it out. I have the OEM intake box and I had not removed it, just the plumbing after it. So, with the box removed I can get in there fine and get to the plug.
With any luck, it should all go back together today.
Great video!!! Thanks for taking the time to make it! How has the valve covers been holding up? No misfires or oil in the plugs? Have you had to replace a coil pack yet?
No problems after 2 years, I did use Nissan valve covers thou! No more leaks around the spark plugs at all, I haven't changed the coil packs yet, I'm at 123,000 miles. But I'm going to be changing them soon! Thank you so much for watching, I'm glad the video helped.
Really good instructional video!! This video has helped me out a lot. I was just wondering.. what did you mean when you said the gaskets were slightly different? I see that u bought the gaskets separately from Nissan and the valve covers from amazon. Did the gaskets that came with the amazon order differ from the Nissan gaskets?
Thanks!
I actually bought the valve covers and gaskets from Nissan and they we're very expensive. So I put a link to the Amazon valve covers to save people money if they couldn't afford the Nissan parts. Now, the Nissan valve cover gaskets have different part numbers, so be sure to test fit the gaskets into the valve covers to make sure they fit perfectly! Hope this helps and thank you so much for watching!!!!
Excellent video!!!
Thank so much for watching, do you think I should release an uncut updated version with even more information on replacing the valve covers on a 350z or is this enough?
@@Zspeed you can never have too much information! I've been meaning to do my valve covers for some time now. Unfortunately some a-holes broke into my storage, messed up my z33, and stole all the parts I had been saving up to repair her. I've fixed most of the damage, and I'm saving up to repurchase all the service parts. I look forward to completing the job with your video's help! Thank you for making these sweet vids for us my good man!!
Thank you for the encouragement, sorry to hear about your 350z! I hope you get her up and running soon!! I think I will be releasing an extended version in the very near future! Take care my friend!!!!
@@Zspeed That's awesome news! And no need to thank me, you're the one doing us all a favor! I will do my best for my 350z, I've had her since 2003! I wish you and your family the best my friend. Keep on keepin on!
@@Zspeed by the way, do you have a Facebook account?
love the video, what happens if your coil packs got mixed up?
No problem, it should not affect anything, they are interchangeable! Thanks so much for watching!!!
Hi Z-speed, I replaced valve covers a year ago, but i have leaking problem again. I order a new set and ready to installed as soon covers arrived. Do you think the sequence on how to adjust screws is important? and the tention on them? My guess at this point is that that where i had a mistake. Please advise. Thanks
Yes there's a certain order that you need to go through when tightening the valve covers, refer to my video. The torque specs are very important and without being properly torqued your valve covers will Leak. Also, make sure that your valve cover gaskets are lightly glued into the valve covers with RTV gasket maker so they don't move around when placing them on to the motor. Hope this helps and thank you for watching!!!!
I ordered a gasket oem from Nissan but the one that came with the new valve cover I ordered looks and feels stiffer and better quality. The Nissan OEM one looks good also but feels more soft and stretchy. Should I stick to the stiff one or to the soft one?
I would install OEM gasket, thanks so much for watching!!!
Hey Z Speed I have a blown head gasket on my 2005 350z and no one wants to do a head job and replace it. I was wondering what should I do I have little to no DIY experience on cars. And shoutouts to you from a fellow Alabamian.
Check out: head gasket and header install by H&H development on TH-cam! It might give you an idea of what it takes to replace one. If your not up to it, call around your area for shops that specialize in head gasket repair! What part of Alabama do you live in? And thank you so much for watching!!
Z-speed thanks for the Z Speed ! and I stay in Montgomery
If the battery is disconnected and you don't physically move the butterfly. Do you have to still do the throttle body relearn, because you cleaned it?
No, you shouldn't have to do anything but reconnect the battery and start it up! Thanks so much for watching!
Do you recommend replacing the plenum spacer while the engine is apart or can the old one just go back in?
Do you mean the plenum gasket? If so, yes I would replace it!! Thanks so much for watching!!

How would you know if a valve cover gasket is bad? Oil in the spark plug ?
Yes, oil in the spark plug tubes means that the spark plug O-rings are bad. Oil around the valve covers, means that the valve cover gaskets are bad. But either one of these leaks means that you need brand new valve covers and gaskets. links for valve covers on are here!!! :amzn.to/2LLcGLE
Nice video very helpful , but im not sure why you removed the knock sensor harness which is under the intake manifold which has nothing to do with a valve cover replacement , maybe it was another harness
You're right, it's not the knock sensor it's the electrical harness, just above the camshaft position sensor! Thank you so much for watching!!!
only reason i knew is because i replaced the knock sensor harness, i had a 327 code after some homework i found that its not the knock sensor but the harness which Z1 Motorsports sells and confirms that most of the time its the harness. I found a video on youtube by Dnali with a trick on its replacement
Thanks for the tip, I hope my harness last a while longer, I have 123,000 miles on my 350z!
Forgot to say you have to do a idle relearn cause you had the tb unplugged...
Yes this is True!
Z-Speed, I'm just waiting for the weather to warm up before I start to do this , did you replace any gaskets on the upper or lower plenum, I asked Z1motorsports and they said most of the time they are reusable whats your opinion , also did you have any problem with the throttle body after being removed was a relearn needed
I bought new upper and lower gaskets for the plenum, but the upper plenum gasket is made of metal and I could see that it might be reusable if not damaged! I would replace the lower gasket. As long as you disconnect the battery before you disconnect the throttle body, you will not need a relearn. Hope this helped, if you have any more questions just ask!
@@Zspeed thank you , I must applaud you for having the best video on this , and also for using hand tools and not a impact drill you read the horror stories of broken bolts its ok for removal after the bolt is broken free by hand , I just ordered the upper and lower gaskets from Z1motorsports thank you again for a great video and personal help
No problem, I created this video because I needed a more step-by-step approach than I could find on TH-cam. So I thought well why not just make one and maybe it'll help other people too! I'm sure glad it helped you, any other questions just ask!
Did you have to unload the vehicle to remove the strut bar or can it done with the car flat?
It would be better to remove the strut bar while the vehicle is on a level surface. It can be done while on ramps, but easier when level!! Hope this helps!
I wonder if I can do it to my car , I recently found out there was oil on my spark plugs , when I was changing them / don’t know if I should take on the challenge
Yes I think you can do it, but to do this job you must have an inch pound torque wrench, two new valve covers and gaskets, and a lot patience! If you have any questions at all just ask!
@@Zspeed and new intake plenum gaskets too, just in case.
Do you have to drain the coolant when replacing the valve covers ??
Whats the purpise of the valve cover built in spark plug o rings....if ur valve cover gasket is not leaking no oil should leak....is it just for safety and not nrcessary?
They should have made the o rings replaceable, bad design!
I recently replaced my spark plugs because my car was idling poorly and was misfiring. While doing so i found there was oil on all passenger spark plugs. Went ahead and replaced them and a hour of driving later I’m having the same issue. Only codes being thrown are for the rear o2 sensors but it shouldn’t effect how the car runs, do you think that the oil is fouling the plugs and maybe this will fix it?
Most likely it's a faulty coil pack! Once you place a spark plug in the hole and torque it to spec there should be no oil leaking down and fouling the spark plug end! Although over time you might get some bleed through. Coil packs usually throw a misfire code, so I'm not sure why you're getting an 02 sensor problem.
So try replacing your Ignition coils, 《AKA 》coil packs and yes after you solve this misfire problem it's time for a valve cover job! Thank you so much for watching my video, anymore questions just ask!
I just replaced the valve covers on my g and its leaking again around the tube seals. Do you think I can add rtv inside the boarder of the tube seals while the cover is on?
Definitely worth giving it a try! Let me know if it stops leaking. Unfortunately, you will need to purchase new valve covers in the near future. Try Z1 motorsports, and thanks for watching!
@@Zspeed actually I did replace them already a month ago.bought one from rockauto.com and one drom 1aauto.com and they both leaked after a month.you can watch my last video..hope you sub ✌
so since the o-rings can’t be replaced and have to buy a whole new valve cover, where can i get them from? where did you get yours?
I got mine from Nissan, but you can get the same quality valve cover from Z1 Motorsports! Also, they have these New metal valve covers out and I believe you can change just the O-rings and gaskets from then on!!!😀🏁👍.
@@Zspeed thanks so much for the feedback‼️ i will look into it, keep up the amazing work👍🏽
I didnt see disconnected the back hoses
If bob ross worked on cars this is what’d it be
Thank you so much for watching!
Hey Z-Speed I was wondering since it's been awhile now on how these valve covers are working out still? My 350 needs the exact same thing but I'm a little worried because of the reviews on Amazon. Any leaks!
I see what you mean about the reviews on the Amazon valve covers, they are a little low. I posted this link as an alternative to buying valve covers from Nissan. The valve covers from Nissan with the gaskets was around 450.00 bucks!! And that's what I used on my car! Now after 2 years, I have no problems at all, no leaks. So if you can afford the Nissan valve covers I would highly recommend those. Hope this helps, if you have any more questions just ask and thanks for watching my video!
@@Zspeed Z1Motorsports sells the nissan covers for 379.00 comes with the gaskets , i also bought Ultra Grey RTV Liquid Silicone Gasket Maker
Thanks for the tip, Z1 motorsports has some great deals on stock 350z parts!!!!;👍👍👏
I’m having trouble getting to the passenger side rear bolt that’s behind the fuel line and the harness. How did you get access and get enough room on that side?
That was very tricky, I had to use a small 1/4 inch ratchet with a 8-12 inch extension. At the end of the extension, I used a 1/4 inch swivel adapter and at the end of the swivel adapter I used a elongated 10 mm socket. I know it sounds cumbersome, but it worked quite well! If you leave me a email address in the comments, I can send you some pic's of the setup. Hope this helps, and thanks for watching my video!!!!! I was also able to use my torque wrench with this setup and achieve proper torque specs.
You can also contact me at zspeed2561@gmail.com
Thanks so much for the response 👍🏻👌🏻. I will try that and also email you.
I have passenger side valve cover gasket leak on my 2008 Infiniti M35 told by a mechanic. There's a lot of burning smell. Is the process the same since i think the engine is the same?
Although the engines do look somewhat similar, the torque specs will be different as well as the disassembly of the plenum. Make sure you buy a car manual from autozone to get appropriate torque specs for your valve cover. Thank you so much for watching, if you have any other questions just ask!
@@Zspeed Thanks
Did you lose pressure in the valve covers when you vented the pcv?
No, but I no longer run a PCV delete, watch this video :th-cam.com/video/fkIaD42NOf4/w-d-xo.html. This is a updated version for the valve cover job:th-cam.com/video/_15ivIVS9_I/w-d-xo.html
Do you mind listing the materials that will be needed to do this, from tools to gasket maker?
Sure, I'll try to put a list together for you this weekend and I'll get back to you!
Sorry it took so long to get back to you. #1 Must Have A inch-pound torque wrench to torque valve cover properly. #2 Permatex Optimum black gasket maker. # 3 socket wrench with 10mm extension, swivel adapter and extended 10mm socket. #4 Basic mechanic's tool set. #5 Foot-pound torque wrench for strut bar #6 You will also need a lot of patience, so take your time, at least two/three days if it's your first time doing this!! Hope this helps and thanks for watching!
It’s no problem, thanks so much!
My valve cover bolts keep popping out. Like the holes are stripped or something. I bought a tap set and rethreaded the holes, no luck. Bolts still pop right out when torquing to 70 in/lbs
Hey Alex, thanks for the question! On my valve cover replacement video go to the 16:30 mark for the valve cover bolt tightening sequence, there is a certain order that the 10 mm bolts must be tightened in to get a good seal. It takes two passes, try 17 inch-pounds for the first pass and then the second pass should be 74 inch-pounds, not 70 inch-pounds. Hope that fixes your problem!! If that doesn't work, try putting blue Loctite on the end of each bolt and repeat the sequence above. Are you the original owner of this 350z? If not, someone my have striped the valve cover bolts before you bought it! Hope this helps you out and thanks for watching my video!!!
@@Zspeed thanks for the reply. I did torque to the specs you mentioned in the video, and I also tightened them in the correct order. I'm not the original owner, so I suppose it is possible they were stripped by someone else
Purchase brand new 10 mm bolts from Nissan, your original bolts might be severely worn, let me know if that works!!
Do I have to drain the coolant ? If not when I loose some coolant from the throttle body do I have to top the tastier and bleed the system or can I just put coolant in the resvior
Radatior I meant no tastier
You should be okay by topping off the reservoir, check your engine temp and make sure it's running cool. If not, bleed the system!
P.S. thanks for watching my video!!!!!
Z-speed thank you ! Gonna go do this as soon as my valve covers come in This is best Video for sure Explained and showed well
Z speed how can I measure the torque when tightening the valve covers? 🙏🏼
All you need is a inch pound torque wrench, about $20-30 bucks on Amazon, or your local car parts dealer, (Auto Zone, O Riley's ,etc) may have one you can rent! Hope this helps and thanks so much for watching!!!
@@Zspeed ok thank you so much good man 👍🏼👍🏼👍🏼
K-A check out my revised valve cover gasket video for even more details:th-cam.com/video/_15ivIVS9_I/w-d-xo.html
Am I need to do this to change spark plugs?
No, you can change your plugs without removing anything but the coil packs!!
God saver!
Thank you so much for watching!!
Is it necessary to replace every gasket? I ordered new valve covers as well as valve cover gaskets but do I need a new plenum gasket?
As long as your plenum gasket has no kinks or bends you should be okay to reuse it!
@@Zspeed awesome thank you! I went ahead and ordered them anyways, great video btw! Another quick question do you highly recommend the pcv delete? Or is it something I can get away not doing or doing at a later date?
I would recommend a non-vented catch can check this video out!:th-cam.com/video/fkIaD42NOf4/w-d-xo.html
I also have a updated 350z valve cover video available:th-cam.com/video/_15ivIVS9_I/w-d-xo.html
Great video! Please explain how I can detach the back attachment that’s on the wiring harness to the valve cover driver side. I try to push down and pull but it does not work.
This was a little difficult to remove, I believe the wiring harness has the same type of clip that the camshaft position sensor has, check out my video here: /th-cam.com/video/JvD4I6N7r34/w-d-xo.html and go to the 11:00 minute mark.
this video with show you how to release the same type of clip, this one is gray, yours should be green. but the clip release works the same way, hope this helps and thanks for watching!!!
Thank you for getting back so quick! Just to reiterate, I should push green tab forward. This I have done but it didn’t budge. Also the angle isn’t good to where I can/know where to put screw driver to wiggle it. It is not like the rest of the other attachments where you press down and pull out, right? Thank you!
Once you push the green tab forward, that's supposed to release the connector. I had to remove my hood to get better access for this project! Just 4 bolts to remove the hood, it might give you the angle you need. Also this clip may be very stubborn, over time the heat of the engine tends to fuse this clip together so it may take a while, don't rush it! I had to use needle nose pliers to remove it after I pushed the green tab forward! Hope this helps!!!!
Good morning! I’ll keep at it with the attachment. Do you recommend I use the super glue or the gasket glue to hold up the gasket. Also would I dab the corners or squeeze a thin line around valve cover slot?
I used gasket maker, use a thin line around the valve cover slot! You may be able to remove the valve cover without disconnecting the engine harness, if it will not disconnect try to remove the old valve cover. This may give you more room to access the clip!
So i did the valve covers , here's my experience take your time and have patience as Z-speed said . The plug for the camshaft sensor(drivers side near the firewall ) was a pain, instead of just pushing down on the release tab you need to slide it until it snaps and then it can be released and when you reinstall it, it will lock itself . For me the passenger side was a pain not much room where the wire harness goes into a plastic shroud and the fuel line piping, a little force with a small wood broom stick worked well , the worst was the lower rear valve cover bolt (passenger side) . I used a 1/4 in drive in this area gave enough room vs a 3/8 drive I also put a piece of paper towel over the socket then pushed the head of the bolt in place , holds it pretty tight .As stated in the video put rtv gasket seal every few inches under gasket sure helps keep that gasket in place
I bought all my parts at Z1motorsports there also is ConceptZperformance there all OEM Nissan
I Change all the gaskets and I also needed the pvc hose and the valve cover cross over hose , both were very hard and brittle i bought the silicone hoses from Z1
took me about 14 hours i did not rush and all is well thank God
Again thank you Z-speed for the great video and advice
let me add since I removed the throttle body while attached to the upper plenum , I found it much easier to to reinstall the throttle body ( 5mm hex )after installing the upper plenum , much easier to install the hoses , As z-speed said do not move the butterfly in the throttle body if your cleaning it and disconnect the battery
I'm so glad your valve cover job was a success, you just saved a boatload of cash!!!!
if i have wheels that are 5x100 what would i need to be able to put them on my z pease answer :(
You need 5 x 114.3 to fit the Nissan 350z!
@@Zspeed yea but the wheels i got are 5x100
Let me look into it, and see if I can come up with a solution for you!
Hey Z-speed, did I hear you correctly....I had to come back to see your video again. You replaced both New OEM factory Valve Covers? Now underneath (meaning-inside) where by "the Spark Plug base is" there should be a Flat grommet gasket as part of the SEAL. You said "THOSE RUBBER O-Rings Go Bad!! at 12:22 "This part is crucial for keeping the OIL from seeping into the Spark plug which ultimately causing the engine to mis-fire!! So you replaced 2 new valve covers??
Yes, unfortunately 350z valve covers are notorious for leaking around the spark plug seals. You have to replace the whole valve cover in order to replace the spark plug seals. You can use aftermarket valve covers are OEM valve covers, hope this helps! Thanks for watching.
Thank you, again @@Zspeed!!! "Have a great Sunday"
Nissan does not recommend this! The new spark plug tube seals should last for at least 80 to 100,000 miles. It could cause problems when trying to remove the valve covers. Hope this helped!
The spark plug tube seals come with the new valve covers, so you will not have to purchase those separately, hope this helps!
Okay, great idea!!!
You should explain that you’re not just removing bolts. You have hoses that are pretty hard to remove with clamps on them…you only showed the easy stuff. Not the stuff that’s going to cause people a head ache.
Is this the same thing for a 2006
Yes, same procedure for the DE and REVUP engine!!Check out my updated video for even more information: th-cam.com/video/_15ivIVS9_I/w-d-xo.html
How well those the product work so far?
So far, I have no leaks around the valve covers or in the spark plug tubes!!!!
Z-speed I don’t know how many times I’ve watched this video lol, great to know it’s still going without any issues. My car started to miss fire and noticed oil in my spark plug tubes so it’s finally time to tackle this. I’m happy you’re also using aftermarket because OEM is ridiculously priced for plastic valve covers lol
Great video.... very detailed but the background music is too much. I had to activate the caption option. Other than that great video my friend.👌🏁
Thanks for the tip, I will be releasing an extended valve cover replacement video with all new audio and lower background music! thanks so much for watching!!
@@Zspeed
That would be great. I just ordered all new valve cover gaskets, crank sensors,coil pack,new mas air flow sensor.
I also replaced the spark plugs and now it has a really bad misfire problem.
Any idea what could be the problem.
Thanks in advance
Ohhh and I ordered new OEM valve covers
Make sure you use NGK iridium plugs, check owners manual. If that's not the problem, it is most likely a bad coil pack. The coil packs usually last from 100,000 - 125,000 miles. Since you just changed the plugs, sometimes just removing one from a plug can damage it. Once they get old they become brittle inside and the wires can tear and that's not always visible from the outside! Hope this helps!
@@Zspeed ok NGK.
QUESTION. what is the tork specks to tight up the plenum bolts and I know that they are numbered
Nice video but about 50/50 on some of the information provided. Not sure what you were accomplishing with disabling the PCV unless you're moving to a properly vented catch-can arrangement. Those small filtered vents will end up providing you a nice oil mist and will be something that need to be cleaned regularly. People forget that an engine is a pump - as much air that goes into the cylinders is also pumped around the crankcase which is why we have to provide some system to control it. Old cars used to have road vent tubes, then we went to PCV which were much cleaner. Also the spark plug tube seals are available as a replacement item so they are serviceable - most people fail at it simply because they use the improper tools. I don't have a problem with using some additional sealant on the valve cover gaskets in as long as it is not a silicone based product. Silicone and rubber simply do not mix. And I have had multiple throttle bodies off and on over the years on different Nissan/Infiniti products and not once have I had to do any re-learning sequence. I think a few people screwed the pooch on that one and it became an internet legend.
Very good, your right on the money, catch can is the way to go not a PCV delete! I have a updated 350z valve cover replacement video, let me know what you think, here is the link: th-cam.com/video/_15ivIVS9_I/w-d-xo.html
How long did this take to do?
Give yourself at least 2 days, so you don't have to rush!
Was it leaking oil or something sir mine has a small oil leak wondering what can it be ??
Wear does the oil appear to be coming from?
@@Zspeed example sense you didn’t chance valve cover same here how would we know if it leaks oil any way to check just for future reference thanks
Usually, your spark pulg tubes will start to fill with oil.
@@Zspeed hello thanks you for the reply see I didn’t chance the valve cover when I chance the gasket do you think it should last. Thought them gaskets
Yes, they should last for a while!!!
What’s the cost for the valve cover gasket replacement ?
Around $428.00 if you buy your parts from Z1 motorsports!
Z-speed that’s all?! sweet!! What about labor ? I just bought my Z today and got a buyers inspection and he said theirs a minor leak and says “valve cover gaskets leaking” and also “replace valve covers, and gaskets” so that’s around $450 or so and then labor could be like 3-400?
If you do it yourself you will save lots of money, if you pay someone to do it, it's about $400.00 +!!!!
That is crazy you cant replace the o-rings, what was Nissan thinking?
You can replace the o rings it is not hard to do at all
Are those true Nissan valve covers or after market?
Nissan's valve covers!
@@Zspeed Thanks . I'm wondering if the Ebay or Amazon valve covers will work?
Better try Z1 motorsports, ebay/Amazon my fail prematurely!
@@Zspeed thanks
Ammm wait do u guys get to make ur owen plates?
Yes, personal plates, nobody had Z SPEED!
@@Zspeed danm wish my country can do that dose the cops do anything
@@Zspeed i bet ur JDM fan like me lol

@@Zspeed we cant do any of those things in my country it sucks
Is this the same process for an 06?
Should be the same if it has a single intake versus a dual intake. Check out my updated Valve cover gasket replacement video here: th-cam.com/video/_15ivIVS9_I/w-d-xo.html
@@Zspeed it’s a single intake
This will work for a 2006!! thanks for watching!
@@Zspeed thank you
Great video although the music volume is too high vs the narration audio. Hard to hear what he's saying. In fact no music would be best.
Thank you so much for watching, check out my latest video with vastly improved audio!!!
You didn't have to replace the cover the o rings are easily replaceable
Make more car vid
The strut bar is not 42 ft lbs!!! Its only 21!!!
No wonder I couldn't Torque it to 42ft lbs. Thanks for sharing!!!!
Also there is a spec to adjust tension on the strut bar after its been off.
Good video. The music was a bit too loud/distracting though.
I ordered new valve covers from eBay because mine were leaking in the spark plug tubes and I ordered them from Auto Parts Zone 2008 website out of New Jersey after 100 miles both valve covers were leaking into all six of my spark plug tubes it was a total waste of money I will not be ordering from them and be advised do not buy these valve covers
Thank you for the information, try ordering from Z1 motorsports. They are supposed to be very high quality!
Give me your car for parts 😍😍
Background music is trash I can't even understand why you would

Thank you so much for watching!👍💯🏁
loud music and guy is whispering, not a great video
Let me know what you thing about this updated version of the 350z valve cover replacement: th-cam.com/video/_15ivIVS9_I/w-d-xo.html
Even watching it at twice the normal speed on your video it's absolutely unbearable with the terrible music that you have associated with your procedure on installing valve cover gaskets. It is an informative video but please remove that terrible music and maybe re-record your audio. Just a little bit of feedback
Check out my new updated video, 350z the ultimate valve cover replacement guide, the music 🎶 has been toned down! Thanks for so much for watching!🏁💯👍
