Thank you so much for this vid, appreciate you sharing! I have the same car so this will make it easy.
Nice video deserve more attention for this one
If you were in NYC i'd hire you to do this for my car in a heartbeat!
We just finished this up. It took 5 hours. We left the injector harness in place cuz we didn't want to disconnect the alternator and AC. Bought the valve covers with the gaskets in them that on eBay for 80 bucks. Save like 1300 over the infinity dealer
👍👍👍
Awesome video, thank you very much. When you clean the intake manifold and other parts like the valve cover, you used brake cleaner? Or something else? I will be replacing my valve covers because as I was replacing my spark plugs I noticed one spark plug had some oil and another one had a little bit in the threads, but I will just replace the valves so I do not have to think about it later. I will not replace any of the intake manifold seals because I do not see any leaks from there.
@Don Hugo, it’s not a bad job if you know how to change plugs. I was using brake cleaner for everything. Just make sure you wipe and let it dry good. Typically if you find oil inside your spark plug galleys, the spark plug seals inside the valve covers maybe going bad. The ones I changed in this video are just the valve cover gaskets which don’t include the spark plug seals. You can first try the valve cover gaskets to see if it solves it, but if you still find oil, you may have to get new valve covers since the seals are technically not serviceable as they’re built into the valve covers. Or if pockets are deep, do new valve covers and valve cover gaskets all at one time. Up to you’
Lmk if that helps or if you have anymore questions.
Thank you I was wondering why I couldn’t find the spark plug seals I guess I have to buy the whole cover , thank you again couldn’t find that info anywhere
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?
@bartolo heriberto, your best bet would be the OEM Nissan gasket since they manufacture Infiniti, it’ll be the most up to date part even if they made revisions to it to improve. Is the VC you bought not oem Nissan/Infiniti? If I was you, I’d use the oem Nissan gasket on the aftermarket VC and sell the other gasket cheap or keep as spare.
Great video... any chance of shining some light on my 2010 m35x, I'm getting a P0011 code. New oil &filter change, replaced vvt solenoid on passenger side, wire harness is good,runs perfectly but cannot pass NY emissions. Any suggestions?
@SmallS I’m not sure but code P0011 states that “the intake camshaft in Bank1 is more advanced than the engine computer has told it to be”. Have you tried unplugging the battery for 10-30min to reset everything?
Also on google there’s some results about relearning to clear p0011, tried that?
@@NODRFTNewOrleansDrift Actually, I swapped the camshaft sensor and found out that was the issue.
What about the o-ring parts? Those area are proven to leak… did you apply RTV to the 6 spark plugs o-ring areas as well?
The spark plug seals are inside the valve covers. Not serviceable by Nissan standards but there’s a 3rd party company that sells a tool and seal kit but I did not change those as mine aren’t leaking.
10:40 what do you have removed from the vehicle where you are able to get a grip on that alternater plug ? its literally impossible to get a grip but it looks like you have more than normal space here can you please help me out this is literally the last connector on this side lol
@dragonstrike12244 at 10:40, I am laying under the car looking up. Have you tried, 1st free up the entire small harness bundle that runs by the alternator. There’s a Ziptied rivet thing that affixes the harness to the alternator bracket, use a pick tool to get that loose, and then have a free harness, it’ll help when you go at unplugging the alternator plug. It’s an awkward sideways pinching of the plug, if you have some compressed air, blow the plug it may help free the dirt/debris and allow a better grab of the plug. When I’m pulling the plug, I give it a wiggle as I pull to free it and hope it pops out. Lmk how it goes.
Hey did you change the spark plug seal and if you did what part did you use pls reply thanks
Hi @temi Romeo, I did not change the spark plug seals. I believe they are apart of the the valve covers so those would need to be changed.
so is the RTV just to hold the gasket in place or does it need extra sealing?
@davaban, RTV is extra security that holds it in place at the corners so the gasket doesn’t fall out the VC groove when you flip it to reinstall, and can’t really see how it seats.
I changed mine but shortly after had rough idle and get the flashing CEL for cylinder misfire. One of my soark plugs was covered in oil so I cleaned it and the tube where it goes. Reason I didn’t bother to change the spark plugs was because I changed them a week before I did the valve covers. I did idle relearn and checked all the connections. I did crack some hoses but I put gasket gasket maker, taped it, and clamped it for the meantime. Do you think that spark with oil could be the issue? It only idles had when stopped in drive and in parked other than that it drives fine.
@Samuel Ortiz, yea the wet plug can misfire and not misfire intermittently. May want to change your tube seals.
When do you replace vq35hr’s engien valve cover gasket?
@urusa you change then when they start leaking.
Hi, I own a g35 with vq35hr and my idle rpm raised from 650ish to 700 rpm ish after replacing valve cover gasket.
Do I have to do the idle volume relearn procedure afterwards?
@Urusa, I wouldn’t sweat it. Could be change of weather being a factor.
@@NODRFTNewOrleansDrift thanks for the reply. Did you reset or use scanner to scan if there’s any error codes after replacing gaskets?
@@Qkfltpdls777 I used a scanner to check but had no codes before nor after.
The pattern to bolt these down is for a DE engine, not the HR.
Any chance you can link the right pattern for the hr?
Me thinking it’s gonna be an easy project then learning I gotta take apart half the engine, solve a 1000 piece puzzle, book a flight to Malaysia, search for captain McChickens lost buried treasure in the golf of guandamian, and start a nationalist uprising in South Africa. I love cars…
@jupiterproductions, hahaha it’s not that bad if you’re prepared and take your time.
Update: replaced them today, now it’s misfiring, I double and triple checked everything and I don’t know what I could have possibly done wrong.
@@jupiterproductions6644 sorry to hear, check your coil packs and make sure you didn’t mix up the plugs.
hi i was wondering how do you remove the pcv hose? mine was firmly stuck on both cv without clamps. just use pilers and pull?
sorry the breather hose between two valve covers
@Bismarck Liu You can carefully use a pair of adjustable pliers. Grip onto hose and kind of massage the hose by lightly clamping the pliers while turning it to break it loose, don’t do it too rough, easy on it, not full tight grip but not loose either. Hard to explain since it’s a feel thing but hope it helps. Try not to yank on it to rip the hose or break the plastic. Good luck, let me know if you have any more questions or how it went!
@@NODRFTNewOrleansDrift thanks but it found ur reply right after i broke it...🥲i am trying to fix it but still thanks !
@@GaleoneOfficial if you broke it and can’t find one new at parts store. Hit up the local junkyard or pap and see if you can get a used one temporary. It’s probably best to order a new one so you won’t have to worry about that or a used one failing.
@@NODRFTNewOrleansDrift thank you so much!
Which viscosity and brand of engine oil are you using on your VQ?! (Am running synthetic 5W30 on my 35HR because am scared of engine oil pressure issue or so due to using thicker engine oil such as 5W40 although i want to use thicker one..)
@urusa I use valvoline vr1 20-50 in all my vq cars. Been using that oil since 2008.
@@NODRFTNewOrleansDrift isnt 50 viscosity too thick for VQ engines since its factory viscosity is 30?..
@@Qkfltpdls777 I’m a firm believer in it, I’m in the south so it’s hot and humid. Oil seems to break down and 20-50 vr1 has been going great not getting too liquidity…haven’t blown engines, I drift all day long, and come home, to me it’s proven/works for me so I stick to it. But may not be up for you though. Oh yeah, my lowest mile z33 is 140k, both my g35’s have over 240k miles and gets vr1 oil, still kicking rocks.
@@NODRFTNewOrleansDrift oh i see that the area you live is very hot and humid.
@@NODRFTNewOrleansDrift Can u tell me which brand I live in south Fl also
About how long it took you from start to finish?
I started one evening and finished the next day, I probably spent 4-6hrs total.

hello , I had a question , I think i messed up once putting everything back together, the issue that I’m facing is that once I turn on the car , it immediately turns back off and smells burnt, is there by any chance you have an idea for me to look to fix? I also had the car sitting for about two weeks before finishing , thank you !
@chrissrivera9043, idk what would cause that but double check everything. Did you plug all the plugs back into the correct connections? What was it doing before you did this job, like why did you decide to do this?
@@NODRFTNewOrleansDrift before it was running good , no issues just that it was taking a little longer to turn on so I decided to originally change my spark plugs then I saw that there was an oil leak in one of the plugs so I then decided to change the gasket . I double checked last night the cables but I saw that the vacuum hose was on the wrong hole , I had accidentally placed the one that’s next to it (I think it’s the coolant hose if I’m not mistaken) then I tried to turn it on yet it does the same thing and smells burnt
@@chrissrivera9043if it smells burnt most likely you didn’t put the gaskets right have you fixed that issue and figured it out
@@Kocaineee yes sir , it turned out to be my throttle bodies , I needed them to be replaced and also do a idle relearn process , i appreciate your advice ! 👍🏼
How long was this process
@jeromeny 2-4hours depending on your mechanical skills.
How long did this take
About 6 hr total, I started in the evening then ran out of light and then finished it next day before noon.
How long did this take you?
About 6 hours
6 hours? holycow, so going to dealership for changing a gasket will cost more than $600?
I’m not to sure as I do not go to the dealer.
hey bro did u end up going to the dealership i might be on the same boat im trynna figure out a price range
@@michaelnossa28 private shop quoted me $1067 parts/labor to replace both sides. They are replacing the whole valve cover not just the gasket
@@ULTMTGMR-rj9bt yeah I got quoted around 1300 for parts and labor so I just got rid of the g and copped a 3.7 q50 lmao
