Iâm glad I seen this video. I was about to change just the valve cover gasket until I seen you point out the spark plug gasket was cracked on yours. So just to double check mine I noticed I to had a cracked spark plug gasket. This car is for my daughter when she turns 16 next summer so I wanted to get it all squared away. Thanks!

What are your thoughts on putting Rtv in the cover groove before putting the rubber gasket in?
in changing the oil in my altima I see a grey paste in the chamber. What does this mean? I'm not seeing the same paste in on the dip stick.
how many "foot pounds" to set my torque wrench to for the bolts of the valve cover it can all be confusing?
+Prophets Among Us Thanks for watching! If you use a torque wrench you will need a wrench that can be set to inch pounds, not foot pounds. We just do this by feel, as it is a plastic cover on an aluminum head, so it can be cracked if you tighten it too much.
I have a 2009 Rogue. Does this video the same and whats the part number for a valve cover? thanks
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?
Thak you so much. I can only imagine how much money you saved me with this video.
+Ryan Secrets Thanks for checking us out! 1AAuto.com
Is it possible to remove the cylinders that contain the spark plugs or are they welded into the valve train?
Thank so much for this video!! Extremely helpful. We used it to do the job ourselves, only issue is that the mouth of the pcv hose broke, and the clamp won't go up to it's original spot when we place it on the valve. Is the only fix to replace the hose? And if so, do you have a video of how to do that?
+SunnyDays If the end of the hose broke you may need to replace it. Thanks for checking us out! 1AAuto.com
Great video as always.
LOL Intro music sounds like Michael Jackson's "Beat It"
Two of my spark plug wells have oil inside of them. Could it be a gasket issue? I havenât gotten any misfires. I was doing a routine spark plug change
About to do this on my SE-R and I was wondering if it needed sealant on any portion. Good to know. Thank you!
Any luck on this? I see this was 4 months ago. Anything different than the vid above? I have a 06 SE-R SpecV and fixing to do the same process. . .
GREAT JOB!!!!!Thank you for making video.
Are the spark hole seals removable. I have a 2005 altima 2.5 sl

Oil leaked into the cylinders when I removed the spark plugs what should I do? I'm replacing my valve cover gasket and boots but is there anything else?
Is it a common issue for these to leak after 15 plus years and over 100k miles... i have a 2005... cleaned and looked for leaks everywhere under the car ,could not find source... today i will check valve cover... currently i use a quart every 700 miles and gets oil drips spots on my driveway... thanks for sharing...
From doing my 2005 Altima, to get more room under the wiring harness, unplug the O2 sensor connector,the cam sensor, and coolant sensor connector and you'll gain much more room when putting the cover back on.
Nice tip. Thank you
Great vid....quick question...the rtv silicone you put in corners before putting new valve cover box back in, is that just a general all purpose rtv or a particular one? Thanks in advance
Whatâs the labor on this kind of replacement??
was the factory cover plastic also???thx
Thank you for this video I have that common problem with the oil leaking into chamber #4 of the spark plug only that one I have all of the parts to replace it but Iâm still not confident enough to do it myself Iâm goin to watch this video over and over until I get it down
+finaljesus Thanks for checking us out!
Did you just replace the gasket or the whole cover
@@1AAuto is this the same proccedure for 2011 nissan altima l4 2.5?
Is the cover needed?
Is it same as the 2.5 xtrail engine đ
hi this is a really good video, just wondering if you have a video like this on how to replace a head gasket thanks!
+Bryn Thomas We currently do not have an auto repair video that covers this particular repair. We will keep this request in mind in the event that we need to make this repair in the future. 1aauto.com
Yeah! That'd be great if you have that! I had a blown head gasket on my altima recently.. wished there were good detail videos to show how to replace it!!
on an altima or on a honda accord.
Yes do a head gasket video ! Please and thank you
I did this job on my 2005 nissan altima 2.5 .I bought the valve cover from advance auto . When I went to put the valve cover on. I couldn't understand why it was rocking on the spark plug tubes.I was afraid something was wrong and brought the cover back and asked why does it seem the holes where the tubes line up seemed way to small.But the said put a little grease on them.I still swear something was wrong because of having to screw the cover down.I was afraid it was gonna push the new gaskets out ,it was so tight fitting .any comments
Have 2006 S bolts are different , what wrench too use
Thank you for the help . You saved me a lot of money. God bless you and what you do âïžđ
I'm replacing mine, but on my torque wrench it doesn't say inch pounds it says foot pounds on one side and Nm on the other what would be the conversion # in foot pounds, I don't want to break the bolts or under tightening them.
The new valve cover I put on my moms I started putting in the bolts that hold in the sparkplug coils but they started to come out. Its the little gold looking things inside the valve cover.I tried pushed them and lightly tap them in but would go in.hope I made Sence. Any help on this would be great.
It's possible the coil boots aren't seated all the way down, it should feel like a suction sort of other than that, disassemble and glue those bolts in lol
Im about to do this to my Altima, After putting the silicone on, should I also run a bead of permatex/gasket sealent on the block surface before putting the new cover on???
*on the rest of the block surface
i've seen others do that, but it's not necessary . the proper tightening sequence , in 2 stages, is more important to evenly distribute the rubber seal on the cylinder head. plus too much of that stuff may squeeze into the oil passages and clog the system
Can the cover be removed without first removing the coils? My coil bolts are stripped.
maybe... but you'll need those bolts to secure the coil to the new replacement cover
Do you need to let the rtv sealant sit or can you apply it and put the valve cover right on?
You put it on immediately, it will set in about 20mins to an hour and be ready to drive in 24hrs with most rtv, you'll want a black/oil resistant type and there is the 90 minutes type and the regular 24 hour cure time type.
Hi can i spray brake cleaner around cylinder to clean oil marks off thanks
I noticed on the link for the valve cover, the baffle is held on by melted down dowels, the one you have in the video doesn't have them. Which one would I get if I ordered through A1?
+dipwadz Thanks for watching! The one in the link will be correct for the vehicle shown in this video. There might be some design differences between the two, but it will not affect fit or function.
Does anyone know how to access the fuel rail on this car model? Do I have to remove the valve cover to do it?
So do the tube seals come with the new valve cover?
yes, those tube seals aren't "serviceable" that's why most people will have to change the whole plastic cover when oil is found in the spark plug wells
Would this fit an 05 nissan sentera
Great concise repair instructions. However I found it unnecessary to unclip the spark plug wires. Less chance of confusing the wiring. It was also easier to pull the valve cover off with the back hose attached and pull the hose off separately instead of fighting the lack of room to disconnect it on the car. Otherwise all worked well. I was especially impressed with replacing the entire cover rather than just the seal gasket. I replaced the gasket alone last year and then it started leaking around the sparkplug well. What's another $150 when labor is involved.
Thanks so much.
With the 06 4 cylinder itâs literally tapped into order when you lay it across the cover. I donât see how you could possibly clip the wrong connections.
How much for the new cover itself? I own a 2008 Altima 2.5
did they fix / updated the problems with aftermarket plastic valve covers? i'm seeing the Dorman and similar failures of made in China ones all over youtube
Any of them made after 2015 by Dorman are fixed
Could this solve a heavy smoke coming from muffler??
Papa Smurf yes, my car was smoking heavily because there was oil filling my spark plug cylinder. Once I cleared out the oil. It was good to go
Can you do one on a 07 Altima v6

Does the valve cover actually come with a gasket or do i have to order it separately, because I see no image of a gasket in the valve cover on your website
update for anyone doing this: the valve cover DOES come with a gasket. It does not show it in the photos on their website, but it is already on the cover when it arrives.
Question why do the bolts holding in the valve cover have to be removed in a certain order?
CORONAKAIZOKU1 I ask the same question
They donât.
If you're replacing the gasket itself and your valve cover is fine. You would want to follow that sequence to not mess up the plastic threading
During removal it's for setting of the threads and for replacement it's to prevent improper squishing and expanding of the gasket when putting it together apparently
well if you're experiencing oil in the spark plug wells, removing the bolts in a certain order is not neccessary. installing them is more important since it's a new cover/gasket & would want to ensure even force on the new rubber gasket
MUCH easier than the replacing on G35 and all its wire harnesses
Thank you
Great video. Exactly what rtv silicon type was it or does it even matter? I see a red paste gasket maker.
I just ordered this part. Please tell me what type of RTV to buy. Thank you so much!!!
+MDA Thanks for watching! Any high-heat RTV should do the job.
Oil resistant is preferred, usually a black rtv
Permatex Ultra Grey is recommended by Nissan.
How do you know this needs to be done? I have one and i think this is the issue but im not sure
+Mr. Ray We recommend having your vehicle diagnosed. Thanks for checking us out!
Are the spark plugs tube seals serviceable? I am a mechanic/tech but I can't remember if I've ever had to replace the entire cam cover for those seals. I'm trying to do my good deed for the year right awayđ. This the fun part about working at a Volvo dealer , Nissan parts typically are wrongđ
Also are the tubes known to leak like the old Mitsubishi / Dodge engines and can I service the tubes. Like I said before my Volvo parts guys ain't up on their Nissan.
No it's kinda silly but you have to replace the entire valve cover panel thing because they put the seals in between two layers that you can't get at but you can order the panel for 80$
Could probably rig up something to fit though lol
Where can i buy the bolts for the valve cover
+alexis saldierna Try searching eBay Motors. Thanks for checking us out!
DeNatured Alcohol works wonders at removing/dissolving silicone adhesives, evaporates fast! It can damage some plastics and rubber so be careful to use it primarily on metal surfaces.
I spray cologne on the fingertip of my work gloves when I need something shiny lol
My first cylinder is misfiring and when I changed the spark plugs I noticed a lot of fresh oil around the first plug. Will doing this valve change help with that oil that's INSIDE where the spark plug thread is? Or do I likely have a bigger issue?
Also, do you know if I'd have to empty the cylinder of oil first? After replacing the valve?
Hey, how did you end up resolving this issue? I'm having the same problem right now
that valve cover seal/gasket is the most prevalent cause. just make sure the person replacing it puts silicone on that area as shown. possibly get an OEM cover too since some aftermarket nissan covers are a hit/miss on this & may have to do the job twice if the replacement aftermarket is also bad/poorly made
@@camille8947 you can cram some paper towels down the hole to absorb it
Recently did this to my vehicle and it still stutters the same with no check engine light also checked if it leaked again and no leak
TheChampEdgar have you tried changing spark plugs and ignition coils?
any OBDII codes? how was the visual inspection of the coils? new spark plugs?
So did you rtv the entire surface or just the ends
Just the ends where he showed, as per the factory service information.
So the tubes for the coil pacs and spark plug . One of mine has engine oil in the well/tube .
Will this kit have the seals to fix that?
Yes the gasket seals come included
Two of my spark plug wells have oil inside of them. Could it be a gasket issue? I havenât gotten any misfires. I was doing a routine spark plug change.
Can u do this job when the car is hot or do u have to let it cool down first?
+jay mac You should let the vehicle cool down first. 1aauto.com
cool = better so you won't strip those valve cover bolts on soft aluminum head threads
What kinda bolts are on the valve cover ? 3 of mine snapped and Iâm having a hard time finding them online
I use Nissan Parts Deal for hardware
Go to Nissan dealer. Only way to replace them.
Joe Guzman did you en up finding the bolts ?
What about the v6 se 3.5 altima?
there are other videos out there about it
I have a 05 which is why I'm confused casue on the 05 you have to remove motor mount
So, there is no a need to use a torque for that?
You should. I use a torque wrench every time
in theory couldnt you remove the need for spark plug tube seals just by raising the tubes of the spark plugs higher to prevent oil from ever being able to get in? definitely would save a lot of money
Having white smoke coming out, burning oil says my valve needs replace but no one will do it. I live in Woodbridge nj. Anyone can help
check the cover/ pcv first... they're the easier cheaper route to go. but also may want to use OEM cover as this part shown as well as Dorman covers may still show signs of burning / using up oil. google or youtube other videos to confirm
@@ricebike Any Dorman valve cover MADE after 2015 were redesigned with a fixed design. Gotta look at the top of the cover to see the manufacture year
If you are replacing the valve cover does it really even matter what order you remove the bolts?
Yes!
Thanks for the video, you forgot about spark plugs.
But everything is fine â€â€â€
What happens when you install without the spark plug valve gasket? I think thatâs what I did
Oil will leak through there.
nope not possible - the spark plug seal is integrated into the cover. if you changed the whole cover then you changed the plug seals. if they are leaking then you might have damaged them or you have another problem.
Shouldn't be no right way to take it out long as you take it out
I did it and car runs perfectly fine again
What is another name for RTV silicon? I'm trying to look for it at autozone. Help please
+Saul Hernandez Thanks for watching! There are several types of RTV that are rated to different jobs. RTV is sometimes referred to as "gasket maker." You should be able to read the packaging to identify which one will work best for the job!

Yes. This Altima is the QR25DE engine whereas the 2001-2007 Nissan X-Trail T30 engine is the QR20DE. Service manuals for both give equivalent instructions.
I pulled up one of my engine coils and it was dripping with oil. In my situation, would you replace the spark plugs before or after the valve cover was off? Donât want debris or oil down in the chambers. Reason I'm asking is: I have ordered the cover/gasket and ignition coils kit from 1A and figure I might as well change the plugs while I'm at it.
+alanb1974 Thanks for watching! In your case it would be best to do it all at once. That way you can install the new valve cover and gasket to help prevent oil leaks etc! 1aauto.com
Thanks. Just finished up the job today. Had a bugger of a time getting the gasket to stay in the groove while maneuvering the cover into place. Took me a few tries and I'm sure I smeared my RTV silicone beads. I tried to mop out as much of the oil around the 3 of my 4 plugs prior to swapping them out. Some oil must have gotten into the cylinders as I notice smoke coming out of the exhaust after I fired up the engine. Quickly cleared up though and all seems good. I have no idea how much the shop would have charged for this job. Thanks for the video and the Cover, Gasket & coils kit!!
Go to a salvage yard
"Donât want debris or oil down in the chambers." do the plugs first then... soak up the oil in the wells first as best you can.
7:39 Wait wait wait so we only add the rtv silicone to the LEFT side and then put the cover on? Or did he just not show him putting it on the rest..
I'm guessing it's just for that specific engine but the same gunk he scraped off using the razor blade you should see it on your engine also so that's where you would need to put it...
It's because it's not raised up on the other side apparently, it's flat and seals tight
is it ok not to put any silicone on the timing cover side. i've replaced the valve covers many times on these cars and never used it and never had any leaks.
+Hector T Talks Thanks for watching! For this model you really should use silicone on the timing cover side like in the video. 1aauto.com
@@1AAuto Thank you! I will remember that going forward with future replacements.
So the valve cover grommets are not replaceable or serviceable,thatâs why you are replacing whole valve cover?
+mckoy lach That is correct, those seals are not replaceable. There could be other reasons for replacement, like the cover itself is cracked etc. 1aauto.com
yea
Same engine as Nissan X-Trail? Looks almost the same. Edit. Just looked it up. VR25DE. Same. Here in Australia it's quoted as being 2.4 not 2.5 which is odd but anyway. Also noted in Japan the X-Trail came out as a GT edition with the SR20VET turbo engine. Nice. lol
This motor is actually the qr25de
Would it matter much if I screwed it in in a different order than you did?
+Rbxy As long as it's screwed in and attached correctly and everything is set the way it should, it shouldn't matter.
