This was exactly what I was looking for. Your video has clear narration, effective visuals and easy to follow directions. I really appreciate you making video, just saved me a trip to the mechanic.

[@krystynleighbanks6442]

This video was very informative and extremely well made. I have a Nissan Altima 2002 with the same issue. You made this repair look very simple. Thank you for taking the time to create a superior video with which to follow along.

[@DIYtime]

Krystyn Leigh Banks Thank you! I appreciate that you also took time and left feedback. And thanks for subscribing!!!

[@sathishbheem]

+Krystyn Leigh Banks thats true it is informative thanks

[@DIYtime]

+Sathish thati Thank you!

[@Anunnakey]

someone told me that i will need to reset the timing after doing this. is that true?

[@Zachattackisrad]

abdulrazack oketona not one bit!

[@ljf241]

Do not put silicone between the valve cover and the gasket. This will make the next replacement nearly impossible. Does not add any additional protection. Add only on the corners of cylinder head surfaces.

[@rjwilliams1986]

My 2003 Altima was facing the same issue - oil leaking into the first cylinder (just like the video!), causing it to misfire. The clear instructions from this video allowed me to replace the valve cover gasket with no fuss or muss. And I am not a "car guy" who does this type of thing much. I really appreciate Temachok for putting this video together - much appreciated!!!!

[@DIYtime]

Thanks! BTW, I'm not a "car guy" either!

[@gerardoescobedolobatos7498]

How much did this cost you

[@poopiehead4943]

thank you so much very thorough explanation answered a lot of my questions that other videos did not!

[@TheTruelakersfan]

Stupid Nissan making you buy a whole new valve cover.At least it’s cheap not like a bmw valve cover that’s cost $400!

[@LeeRalph100]

Hi, I am working on my daughters 03 altima, I did not notice oil in the well until after pulling the plug, stupid question, oil ran in to the cylinder on top of the piston, any worries? This should seep past the rings back into the engine correct. Thanks for the help

[@keeks2freakssseqz229]

I had this same issue. And would like to know if it would cause damage to my engine

[@miker.5495]

Unnecessary use of gasket maker that will only cause more problems down the road. Use gasket sealant to hold a new gasket in place and only use rtv where the manufacturer service manual says to do so.

[@larryb5498]

DAMN!!!! This guy has the fastest fingers I have EVER seen and I am 66 yrs old!!

[@kevinrosemary1589]

Its fast forward Larry

[@farapjoeboss8717]

Can you help please. I found oils all over the agien. But I don't know the came from. And the service light came up....and the car still.work good

[@dobisayek]

Thank you for not using "Heavy Metal" sound in the background! I've seen glue (in spray form) applied to gasket, is it necessary ?

[@DIYtime]

+Sid G. :) No heavy metal... Official Nissan repair manual doesn't say it's required.

[@gdb5448]

Applying gasket maker all the way around the valve cover and on the head surface is a very bad idea. It will not give you "extra protection" and usually causes leaks due to the gasket not being able to seat properly. Do you think you're smarter than the engineers at Nissan? If the facory doesn't do it then neither should you. It will also greatly increase the difficulty and time requried for this repair the next time around. Only apply a small amount of gasket maker(and use the grey, not the black) to the two corners as done from the factory.

[@DIYtime]

Thank you for your input, gdb 544. 1) You are absolutely right, it's not necessary to do it, just as I said in the video and it will take longer cleaning up next time 10 more years from now if I still have the car and it's still alive with the same engine... It may not give much "extra protection", but it wont cause problems either. Excess maker will be squeezed out as long as you put in the engine cover before it hardens. Mine doesn't leak till this day. 2) Black maker is pretty much the same as grey and works for same temperature and applications. The only difference is a sales pitch of aftermarket manufacturer. It is supposedly has "higher oil resistance". 3) Respect to all Nissan engineers. I wish I was half as smart as they are. They've done incredible job with that GT-R and more.... I'll consider putting your recommendations on my video. Thanks again. Have a great day.

[@cosbyutube]

on a 2006 nissan altima you cant buy these seals. you have to buy the valve cover. so to answer your question.. YES i am smarter than a nissan engineer. $5 oppossed to $140 for a needless part. again. yes i am smarter than them. also i'd like to add that my daughter will not be buying another nissan if she expects me to ever work on it. what a piece of poorly designed junk.

[@justinnewman9234]

*thinks about the precat failure issue on these engines* *thinks about the butterfly valve screw issue with these engines* Gosh, you know what? Maybe the engineers at Nissan aren't the end all be all...

[@kevinrosemary1589]

You think you know!!yet you are here watching a tutorial video!😂😂 LITTLE SMART ASS!

[@AndrewFord]

Bullshit!, in reality based world "the proof is in the pudding" factory way fucked me good! Besides Factory way says to treat "Head Gasket" this way but not "Valve Cover" (Upper one) what since does that make when Valve Cover is made to keep out oil but ends up leaking anyway? Instructions else where based on REAL WORLD BASED REALITY say you can get 200,000 out of Gasket seals when applying the Sealant so....do it the right way because every video about head gasket BY MECHANICS FIXING customers problems says and show them doing it period!...what the WORLD's wrong but the factory is right?...same idiots who produce manuals with ALL KINDS of improper steps and advice that they retract and update in their later versions so...

[@Doe8441]

I put a new valve cover on my car and now it's oil I'm the spark plug hole and it smoke on start up what could it be and yea I put the valve cover on rite it could be a faulty valve cover???

[@DIYtime]

Ishma Cheeks Where did you buy valve cover? Is it good quality? Did you also replace the gasket? Did you have the smoke before?

[@BewareTheLilyOfTheValley]

Oh, how I wish it was this simple with my car, haha! I just watched this for the heck of it but I have an 04 Saturn L300...a car that the manufacturer's decided to tuck half the spark plugs kind of deep (gotta remove gas lines and other things). *sigh* So, I'm watching a little bit of everyone's videos to help me out since few videos feature my car :) Thank you for this!

[@SimplyChem32]

Great video and demonstration. What a terrible design for a valve cover~ having to replace the entire assembly.

[@DIYtime]

Tell me about it

[@jesusalanis4999]

The stupidest thing Nissan can do, put a plastic cover on the metal. I have a 2001 Sentra, it's a piece of shit, I had a lot of problems. I miss my Honda Accord.

[@DIYtime]

Yeah, pretty cheap non serviceable design.

[@Hogib35]

I took out the spark plugs while their was some oil on some I’m sure it’s fine no it’ll burn out when I turn the car. Mine is a Altima 2006 3.5

[@papitosabe]

One thing...for newbs...when tightening, make sure you use in-lbs, not ft-lbs. My dumbass used ft-lbs and broke 2 of the bolts off. I didnt know in-lbs existed and screwed up.

[@DIYtime]

😬

[@rbell944]

I came looking for info on replacing the valve covers on my 05 Maxima but still chose to watch this. This was by far one of the best and most informative videos ever. Easy and clear instructions. Thanks for making it.

[@DIYtime]

Thank you! I really appreciate grateful people!

[@rbell944]

Wish you lived in Georgia or could make a video on doing valve covers for the 05 Maxima! It's going to be harder because there are 2...the rear is hard to get to

[@DIYtime]

Yea, working on 6-cylinder engines is a lot more challenging... When I was doing mine, I also coldn't find much info in how it's done. What really helped me was official Nissan repairs manual. It's good to have it if you like repairing most of the problems by yourself.

[@lavirecord6467]

Temachok do u mean that I can use the same old gasket cover, but clean it very well?

[@paynelcasey]

Great video. I had oil all over one of my spark plugs. I need need to do this. May get the new valve cover painted for bling

[@SoufBouchahati]

If I cant remove the spark plug, how am I supposed to clean up the hole and the spark plug from all the oil ??

[@DIYtime]

Use brake parts cleaner, paper towels and compressed air...

[@whocares5188]

you shouldn't put gasket maker everywhere that can actually make it leak. ask how I know

[@davidvalens3337]

Where should you only put it?

[@pascaljose5010]

good video ... i have misfire cylinder #3 .. after i removed the sparks plug i notice some oil at the botton end inside spark plug tube #3 . ... what's the name of the tool you used to tide those volts back on the valve cover ?? ..

[@DIYtime]

pascaljose5010 Torque wrench.

[@darvil9210]

I have replaced the valve cover twice because the same thing keeps happening with oil leaking past the #3 & 4 tube seals. Any idea why this is?

[@DIYtime]

+Darvil Reyes Sounds like pressure bilds up inside crank case and it blows out gaskets. I'm thinking maybe issues with PCV system. Good article about it here: www.agcoauto.com/content/news/p2_articleid/197 Also, here is my video how to replace PCV valve and hoses if you have The same Altima: kzbin.info/www/bejne/pomvY3ePnrZrpK8

[@kennethstanislaus5649]

thanks for the vid. I learned a lot today. not saying that I will do it myself but at least I know what the mechanic is doing

[@stevenA44]

Perfect video for my car. Mine is a 2005, but has this exact issue. I will have to gather all the parts, including replacement spark plugs. This was really neglected when I bought it. It was running great until last week when this miss-firing issue started. I was assuming that the spark plugs just needed changing, but when I took one of the coils off and seen the oil in the well, then I knew I had a much bigger issue. Thank you for making this video. I seen your other video on how to clean out the oil from the wells and this one popped up after it was finished.

[@shekharpathak1642]

Hey thanks for the informative video. Sad that I found it after I ran into a problem. So, think I let some of the oil get inside the valve while taking out the spark plug? How much oil is okay for that to happen and is there a way to fix it after it has happened?

[@derekpaul79]

How do u get oil out of valve cover and sparkplug when u replace them

[@DIYtime]

[@SC35VOXX]

I'm going to do this on my daughters 2004 nissan maxima, because I can see the gasket is hanging out on one of the curved corners, on the left front side and is leaking oil. Hopefully I do the job right and not end up with my fingers stuck together lol.

[@kikokhoi6017]

I have a Nissan Altima 2.5 SE, and they are saying i have to replace the whole cover, do i have to replace the cover with the gasket or can i just replace the gasket? the tubing along the edge. because i checked and the one you linked doesnt fit my car its a 2.5 but all they give me an option for is 3.5

[@DIYtime]

What year is it?

[@roddydykes7053]

Oh man this looks so much easier than on my 350z with the longitudinal V6... got the whole thing apart and I’m afraid of pinching the gasket on something because it’s tight as fuck in that bay with all the wiring harnesses, fuel lines etc

Thanks!

[@NFLYoungBoy223]

Hey anybody I have a 2007 Nissan Murano with 193,000 miles and I was just doing preventive maintenance by changing the valve covers because when I changed the spark plugs at 170,000 miles one spark plug was covered in oil the ceramic and where it sparks at and changed the 3 rear ignition coils but anyways this week I replaced the valve covers front and rear and that took me 4 days since it’s very cold in Chicago and it was snowing and so when I was working on the front one I had the front ignition coils in a drawer and they were kind of getting snowed on so I just wiped them off and closed the dresser to dry them and install them tomorrow so when I put the car back together I had a code that read P0081 then I looked around the engine and I just reconnected a harness and I reset the code then it was running fine for 30 seconds then it got to running rough again and got a code P0300 and wonder if it’s the front ignition coils but I replaced all the spark plugs at 170,000 miles and only the rear 3 ignition coils

[@angelisone]

I like it because very little cut & editing on the video. Next time don't buy Nissan & Infiniti because they will not sell you just the gaskets & tube seals (spark plug gasket). You have to buy the Value Covers and then two gaskets with can run over $900 in parts. Again, nice video that you also showed us the torque specs while many do not.

[@DIYtime]

+angelisone Thanks, and yes, buy Toyota or Lexus instead....

[@angelisone]

+Temachok Working on an Infiniti G45 and Nissan 350Z are no fun. Valve cover on these are over $400.00+/each, you have to buy many gaskets. Aston Martin, Ferrari and Porsche are nightmares.

[@DIYtime]

+angelisone :) Definately not fun!

[@angelisone]

+Temachok The Altima valve covers are little bit easier to get at than those other high end craps. You may want to replace the water pump & not the timing because yours has a timing chain. Again, nicely done & showing us & taking your time out for us.

[@DIYtime]

+Juan Lara He probably ment how much it cost at Nissan/Infinity dealer including parts and labour.

[@johnaranjo2059]

dude never put rtv and a gasket. terrible ide and never spread it with your finger first dude thats not how rtv works. when you compreess it thats how it seals. you really only need it on the came shaft bearing retainer aka the raised part. what you really should be using inside the cover before you put the gasket on is gasket sealant.

[@ag6477]

Excellent step-by-step guide.

[@racerx143]

How did this solve your leak into the plug hole? This gasket has nothing to do with that part of the cover.......and all that extra sealant.. cringed a little bit.

[@DIYtime]

Well, the thing is, when I replaced valve cover, it came with new PCV valve, which I believe was the root cause of the problem. Stuck PCV doesn't releave pressure builtup, causing gasket and o-rings failure. On that particulat Altima plug holes gaskets are built into the valve cover, thus directly related. As far as extra sealant... yea, totally unnecessary, but it won't hurt eather. I saw someone doing it... shouldn't have listened...

[@joshd7955]

Hmm. I have a 03 Sentra SE-r and had oil with my plug as well. Built in seals to changed V/C. Two years later the same thing happened. I didn't change the PCV valve though. That might have been my mistake, not checking it either. I found this customization of the cover but haven't fully got the dimensions on it other seals and spark plug cylinder to match up. yhst-13387653796039.stores.yahoo.net/diynivqvacor.html

Thank you so much. Have an 02 altima and noticed oil around the valve cover (outside of engine). Had a flashing SES light while driving causing major missfires. Removed the ignition coils and two sparkplug was filled with oiled. The gasket seal and spark plug tube seals are both bad. Now i know its a job i can do myself.

[@justinwilliams5270]

where did u get spark plug tube seal

[@darvil9210]

+justin williams the spark plug tube seals are embedded into the valve cover and can't purchase them separately. If you have bad tube seals you need to get a new valve cover.

well done video sir! I will be fixing myself thanks to your video. One question though: what did you mean at the end, after you had tightened up the bolts, about it being done in 2 steps? Thanks!

[@DIYtime]

Don't tighten them all the way in right away. First tighten them all to the first spec, then finish tightening all the way. This is done to prevent overtightening on any one side when gasket gets misplaced or warped.

Depends on gasket maker brand you using. Just follow whatever it says in installation instructions.

Valve cover gasket leaks can cause misfire? I thought leaks to Plug well only?

That's if considering gasket and o-rings as a set. Cuz you normally supposed to replace both at the same time. On many cars gaskets and o-rings even connected together.

[@vicsamboncs]

So I’m in a bigger bind. I started this repair with a po304 code meaning cyl 4 misfire. I replaced the valve cover and gasket along with the pcv valve and now am getting a po300 (multiple misfires) code and the car is shaking vigorously at idle and vibrates during acceleration. Please help!

The check engine light is back on and it is still reading Cylinder 1 misfire detected - any ideas why I'm still having the same problem.

[@DIYtime]

You may need to replace spark plug wires and boots. Does your car shake / has no power? May be the error code needs to be erased. Unplug battery and honk to release all charge, then see if the error goes away.

[@OneMomentGaming]

My nissan altima 2005 3.5 se engine is shaking when at low RPMs and the Check Engine Soon light came on. I had autozone put a reader on it and got codes P0011 and P0300 engine misfiring and cam shaft error. Is this a possible cause? Thanks

if you see oil in the spark plug well areas after you pull out the ignition coils... that can be a cause for the p0300

[@DIYtime]

+lalo Miranda If that hose is cracked, it may create vacuum leak. This may decrease performance and fuel consumption. It may also throw off car computer readings. It is better to relpace it if you can find replacement. Or, if it has a little slack, try to cut off the cracked end.

Raul Ramirez Basically follow the instructions for whichever gasket maker you are gonna be using. Mine said to let it dry for one hour. It may be different if you have a different brand/type.

Hello I'm trying to replace a valve gasket on a 94 crown Victoria and the one they have in store is totally different from the one replacing...it's a blue rubber without the holes thats on original one And auto parts says that the kind my car uses...so how do I apply this one...thanks #stumped

[@StratMatt777]

+Stephanie Montgomery Return it to the store and get the right one.

I just replaced my valve cover gasket and now the engine turns over but it does not start! I replaced this gasket before no problem. I don’t know what could be wrong.. no oil in plug tubes, put everything back in order.. help

[@DIYtime]

What car is it? Did you do anything else besides valve cover gasket?

[@cazimmerman211]

The torque wrench step is a bad idea. Those screws are too small to torque down. I followed this video step by step until I used the torque wrench and snapped the screw off in the head. Now I’m really in trouble. The bolt snapped at 20lbs of torque.

[@DIYtime]

Did you use in-lbs or ft-lbs? There is a huge difference. 20 in-lbs shouldn't have strip that bolt. These are the specs from the official Nissan repair manual.

[@john2024killuminati]

You dont need the rtv that's is what the gasket is for.

[@DIYtime]

It is required in a few places only, but overall yes, it is not necessary, but it wont hurt either.

[@ricebike]

so why did he mentioned that it was needed for that one side of the valve cover?

[@AndrewFord]

Nice job and great editing!, mine is leaking next to Thermostat housing (2001 Chevy Metro LSI - but is oil so... I replaced With kit but following stupid OEM directions per Costless employee advice, finding out hard way, it slow leaks to outside EVEN MORE! Re-doing Permatex Hi-Temp (650F) Gasket Sealant (Red). I liked the way you smeared it after applying to 2nd bottom-engine block, and I will do the same. Update: So sealant went great but wasn't the Oil Leak problem, because it's still leaking and more apparent now. It's leaking from outside the valve area down from underneath (Magnetivity/Gravity) directly from highest area...the Sensor directly ABOVE the Thermostat Housing; catching onto the bolt-on metal ledge of Thermostat area. Don't know the exact name but EXACT problem and pic can be found on the Blog covering the problem..... geometroforum.com/thermostat-housing-leak-t30186.html

[@DIYtime]

Thanks!

[@AndrewFord]

It was my oil sensor O-Ring area seal basically exactly like bad seals in vid but bigger ...costless tried to match it but just couldn’t and that SEAL ONLY COMES IN $75 entire engine seal & gasket kit for rebuilds, breaking-down entire engine block, A different long time experienced employee this time said he would trust Permatex high-temp sealant over a new OEM RUBBERY SEAL NOT made for long-term anyway...I agreed, made a heavy duty fat seal squeezed into round groove, stopped leak, headed to Hollywood south driving 1,000 miles 10-days ago, and still running strong!

Nice!

[@gurjotkaur5644]

Hi there, Is it compulsory to fasten the bolts into numeric order. What can I do if I got 3 cylinder engine with 6 bolts. Thanks

[@DIYtime]

The main purpose of that is to tighten them evenly and not create too much pressure on one side, while other side is loose. That could displace rubber gasket. If you tighten bolts across from each other gradually, you should be good.

[@goodnightvids]

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?

[@DIYtime]

I would use OEM. Usually are they better. It probably better to have it soft, to contract & expand from heating/cooling off.

[@Nighn_9]

Would these problems cause the car not to start? Iv had the misfire already but never got it fixed and now my car cranks but doesnt start. I know doing this would fix the misfire, but would it also make it start again?

[@DIYtime]

Do you have the same Altima? I had no start when Crankshaft positioning sensor broke. Scan your car for error codes to get a better idea what's wrong.

[@triplebogeysallday]

The video is super helpful, but Can you explain or show how to do the temporary fix with the gasket maker on the spark plug tube?

[@DIYtime]

You can put some gasket maker around spark plug tubes to stop oil from leaking out. It may not work if O-shaped seals already fell off like it was in my case. In any case, replace valve cover as soon as possible.

[@triplebogeysallday]

ok, also another question came up earlier today. is there any other inner tube lower gaskets that can be part of the problem? if so, what would you recommend?

[@DIYtime]

I think this is what you looking for: kzbin.info/www/bejne/Z5DSoWOdl5uAm5o

[@ARCADEGHOST]

Wow, this is much easier than the 07-12 Nissan Altima. It's so stupid that you have to take an engine mount off to replace the valve cover.

[@DIYtime]

Agree 100%. I have 07 Altima right now and I need to do the same thing. Way much more trouble...

[@drock1383]

do u have to drain the oil before doing this? im thinking no but not sure

[@DIYtime]

No, oil level is way below.
