today i changed the valve cover gasket on my 1979 chevy c10 stepside truck and it took me 30 minutes flat from start to finish, thank you chevy for the good old days of well built machines that can be repaired without major headaches lol
Thanks for the video. Folks need to pay attention to the EGR gasket that falls inside the engine when you pull out the manifold. I did not realize it was missing until I read comments below after the fact and suffering a vacuum leak which led to the engine not idling. I recommend folks change the manifold and throttle gasket with new as well. This job was not a walk in the park! You need two persons to do it.
Common problem with a 4th gen Maxima is a plugged EGR vent tube. With the manifold removed, it is a perfect time to clean it out. Your video at 11:23 showed the EGR tube fully plugged with carbon deposit. The intake manifold is probably plugged at that same connection point as well. OBD Code P0400 is most likely in the near future for that Maxima. Good video and I picked up some good tips along the way...Thanks for posting it.
You are the man my brother! i have the same car 1998 and its been sitting in the driveway. for a couple years........and i need also a new Valve cover gasket. thank you and i appreciate it.
'If all goes well, I should be able to take off these four intake bolts and hopefully it will lift up, unless i missed something' - this is how I feel every time I pull an intake manifold... It's always something!
incredible pain in the azz just to get to valve cover, i have the '97 maxima with 156,000 and has never been into, im sure it will need new plugs,valve cover gasket,and possibly coils soon,if i had known it was this much work to change the 3 rear plugs i would have NEVER bought this car,i will drive it till it dies and let someone else handle this nightmare lol, thnx for the video.
Your leak is not the rear valve cover gasket. You need to remove all the timing chains and the outter and most importantly the inner timing cover. The oil leak is caused by the bad o rings between the front of the engine block and the back of the inner timing cover. I worked for Nissan and fixed many of these cars. Takes me about eight hours to do this repair.
good job! But do not use too much silicone at the square corners since the excess will glob into the valve cover, maybe break off and clog an oil passage somewhere. Just enough is more than adequate.
I plan on tackling this job soon. Good tip you should also replace the fuel injectors and manifold gasket so you dont have to worry about removing all these parts again.
Excellent video thank you its going to make changing my valve cover gaskets so much easier now i know where and what to disconnect on my 2000 maxima your videos have helped me maintain, service, and keep my car running smoothly and safely much appreciated for your time and effort put into these very informative videos
Excellent video, Just done a 98 Hyundai Sonata V6 V3000 same as you done replacing the rear gasket had leakage both valve covers the rear being the worst , Thanks heaps for your help and time
+Auto Parts Direct To You I recently did my coils on my 97 maxima and I lost alot power and and gained a really bad misfire what should I do? my service engine light flashes on and off
Did you replace them all at once? Did you also replace the plugs? It's entirely possible you got a bad one out of the box / didn't make good contact with the plugs / etc. Also double check your connections between the wiring harness and the coils, the connectors sometimes need cleaned / reseated.
+Chris Thomas I've did all that, I noticed before I replaced the old coils that one was disconnected so I connected it and my car ran good but I decided to change the coils any way then the shake started happening worse....
low pressure power steering pump clamp. reach up into the foil sleeve and see if the hose clamp is lose. a good indication would be if you smell burning ps fluid through the cabin air fan when you crank the wheel over hard.
Thanks! The reason we did this job is because it was leaking engine oil very badly from the rear valve cover gasket. There really isn't any other benefit to doing this job. It won't change how it sounds or the performance of the vehicle. As far as the black hoses. They are probably ready to be changed. If they feel hardened or brittle at all then you want to change them for sure.
Yes, thank you. On the video it looked like there was none. After reading several forums I decided to change it as well plus the two underlying gaskets. I just hope it won't be to much of a job.
Thank you. just did mine also by watching your video was very helpful and was good opportunity to find out EGR was clogged and oil in my spark plug number The toughest part is removing the 4 bolts in the back of the monifold
Getting to the hoses and bolts that are feel by hand only, would make this a difficult job for me. And getting things back on the right place good and tight like those hoses, man, this seems like a pain in the butt job. But I appreciate your showing how this goes on, darn you Nissan.
The rear valve cover gasket replacement itself calls for 2.8 Hours of labor, I think most shops are probably about $100 per hour labor rate now, so that'd be $280 in labor, plus the parts. Of course if you do it yourself you can save a good chunk of money :)
Good video except I would be pretty mad if I was the owner of the car. He brings it to you to fix and you don't replace those two missing bolts. Wow! Another reason to do repairs yourself if you can. It doesn't take away from the video. It's was very helpfull in doing this job on my car. Thx's.
A simple spark change become this for me. The rubber of the coil got stuck when I pull it kinda looks like it's melted to the surroundings, will be trying this guide and hopefully I'll be successful
Thanks for a great video and very well explanation. I would highly suggest when performing this job, one should also take out the EGR Tube and clean it. There are some websites such as forums.maxima.org/4th-generation-maxima-1995-1999 show how to do it avoid check engine light on when this tube has carbon built inside.
Adding a medium thread lock(blue) on valve cover bolts thread assures that they wont come lose in future. I found 50% leaks are due to losening valve cover bolts by time. And apply small amount oil at spark plugs tube seal also make valve cover slide very easily. Rest of the video looks good. And please dont bang thing on the top of the enging. Find proper banch or floor to do that.
This video was incredibly helpful. But what wasn't helpful was the two bolts holding the back of the manifold to the bracket and the two bolts holding the EGR tube to the manifold. This project took way longer than it could have. The location and tight space between the back of the manifold and the firewall made this project last at least 2 hours longer than necessary. I tried all kinds of 12mm tools, and had a really really hard time getting those bolts loosened and ultimate free. I even lost a 12mm wrench down the back that I couldn't get too until I finally removed the exhaust the manifold. I’m mid-project right now-so I'm NOT looking forward to putting those bolts back. Like this example, I will probably leave the two bracket bolts out. The Nissan engineers who decided this was the right answer should all be walked outside and shot. I hate when projects last much longer than they should because of wicked stoopind engineering decisions.
Hi, are you talking about the intake manifold gasket? (the one with 6 holes), there actually is a gasket on there, unfortunately watching the video again, we never mentioned it. That gasket is technically called the Upper Plenum Gasket, or upper intake manifold gasket.
Sorry I don't have an exact list of what I used, but when working on a Nissan, they were kind enough to use only certain size nuts and bolts, if you have the following on hand, you should be fine: 8mm, 10mm, 12mm, 14mm, 17mm Shallow sockets,, Deep sockets,, and Wrenches.. That small assortment will let you do just about anything on the car and is probably all I used in this video.
thanks for this video im actualy doing the front gasket .i was wondering did i glon it with permatex ,thanks to your video great detail .i hope thats what is where the oil is leaking .,the price of 62.00 for the kit is over priced. ,i blame that on nissan..
Wow this is a great video I am going to do mine this weekend and s/o to the camera man great work am about to save some shop money on this one. Thanks again for the help. I have a 96 Maxima some engine so I shouldn't have no proplem affter looking at this.
The labor cost is free if you do it yourself! It would just cost you the price of parts, otherwise you'd have to check with your local shops to see what the going rate on a job like this would be.
like your video their is a video on you tube that says to tork to 71 lbs don t do it the bolt will break off i recomend the 2 finger rule about 20 lbs.
Hi there! We recently had this done on our '98 Maxima, about 4-5 months ago, I just checked the coolant to discover that it has gone rusty. Is it possible that because there is a coolant line under the manifold that has to be disconnected in order to remove the manifold, that could have introduced air into the system causing oxidization somewhere? Either way I'm getting it flushed out but it would be nice to know. Fantastic video also! Very informative.
hopefully the engine is ok but doing a flush and making sure the proper mix of coolant and water is installed is important, coolant helps prevent rust and too much water can allow rust, also while doing a flush properly, they can bleed out all the air so that should not be a concern, the water pump does have a metal impeller on many models and that is also known to rust, looking for good circulation during a flush and monitoring the flow as the thermostat opens and closes is one way you can see if the water pump blades are actually moving coolant.
Whew! Thanks very much for the video.. I’m thinking of tackling this project on a 2000 Infiniti i30 which looks to be identical to that year Maxima because after doing changing the spark plugs and coil packs and ignition condenser to clear some engine codes (they’re clear now) I noticed oil in the #3 #6 #5 & #4 spark plug chambers. I can see that the spark plug seals are bad and brittle and allowing oil to get in. There are no leaks with the valve cover gaskets but it seems I have to take the valve covers off to get to the spark plug seals! That’s all that can cause oil to pool in those chamber right. The car runs fine after the tune up. ??
Tony Gianni yes you are absolutely right and in the right track, replace those vc gaskets and spark plug seals and u r good to go, yes the valve cover has to come off to get to the spark plugs seals, so might as well replace those also
APDTY ... thanks again! It’s a pain to make videos like this. I’ve done some but I never post them to RUclips (I know I $hud) but it just slows me down so much. It’s hard to get the right angle with the phone and I guess a tripod is the way to go but nothing like zooming in with a second person. Then you have all these critics who don’t have half the skill you have who sit back and nit pick on every thing you did differently or wrong. I’m annoyed easily. I said to myself.. this guy cursed like 20 times off camera doing this job.. LOL! You’re the man! Thanks again! If I decide to fix this for my stepdaughter I have a good idea of what I’m getting myself into. She gonna hate the bad news of having to buy more parts and maybe even the same parts again but emissions are due in less than a week to renew the tag. It just passed emissions with what I’ve done. But I know (pretty sure) the oil is going to fry the spark plugs soon if not the coil packs too. :-(
Great Video, My Question is should I sell my 2008 Infiniti M35 with ( 1. CAMSHAFT Sensor Seals Replacement, 2. Rear Main Seal Leaking, 3. Multi Oil Leaks, and 4. Service Engine Soon Illumating when the oil is low ) The car has 160,000 Miles. The Book Value is $2,300. My question is does it make sense to keep the car and repair these issues?
OK, I see. Well, I believe mine is leaking as well. When my engine is hot while sitting at a stop, there is white smoke that rises from under the hood on the right side of the car. So I suspect a leak from that gasket is the reason for the smoke. Also, where is the best place to purchase replacement hoses for all of those hard to reach hoses you had to take off under the manifold?? I guess AutoZone or O'reiley's would be a good place to start. Thanks again for the help!
@@alex.millwood3406 yes ,it did. Valve cover gaskets fail over time. LOL this is an old post but I did learn over the years. I took my car to a shop a while ago and they repaired it. Now, I try to do most of the maintenance myself. Good luck.
I just started watching this video. Why was the valve cover gasket replaced?...my 98 v6 is leaking a few drops of oil lately on concrete driveway. there is much dried up oily residue around the valve cover seals and block. It also smells when you get out of the car possibly because the oil is heating up on the engine block and its giving off a burnt smell. I think I can handle this project. Thanks in advance.
The valve cover was leaking on this vehicle, It was leaking bad enough to be dripping on the rear exhaust manifold and causing the engine to smoke from underneath the hood. It was also leaking badly onto the ground.
Sure, recommendations would be to get good gaskets like FelPro. Also the smell may stay awhile even after replacing the gaskets as it has to burn off of the exhaust manifold. You can try cleaning it off but should catch all that runoff as it can damage a concrete driveway or garage. Also not good dumping oil on the ground anyway.
Will these valve cover gaskets fit on a VQ30DET? I'm dreading doing this job on my Cima; if it looks hard on this Maxima, my VQ30DET has even more things to remove to reach them. Looks like a full day job.
Getting the timing chain aligned properly is critical, I would suggest just following the repair manual to a 'T' when resetting all the timing components. It can be a little tricky and may take more than one try to get it correct. Just double and triple check everything as you go.
jairoh alford it’s probably the rear valve cover gasket that’s leaking on to the exhaust manifold. Burning off causing the smoke. My 96 is doing the same. I will be doing this repair myself and save some money.
Hey, I have a 95' Maxima SE. Okay... so what benefits will I receive from changing these gaskets?? Will the engine sound better after doing this? Will I get better performance from my engine? I just changed the PCV valve a few weeks ago, but I should of waited because I see that while taking the top intake manifold off you can easily access a lot of the needed periodic maintenance areas. But great detailed video man!!
When the timing Chain break doesn't mess up your vows in the head to make it misfire don't want to spend a lot of money and it not work please enlighten me on this matter thank you and God bless
Hi there,, I'm about to do this to mine, now do you or did you have to change the intake manifold gasket as well. I brought a gasket kit but never had the intake gasket included thanks.
Ash Jod yes you would want to get an intake gasket as the intake will need to be removed to get the rear valve cover off, it’s not too bad a job really, thanks for watching and good luck
Which could be the function for the two last hoses you disconnected before taking off the intake manifold. It seems they flush hot water to the base of the intake manifold. I´ve just bought a car like this and it has broken a pipe where must to be connected one of this hoses. Do you think this problem could cause a higher gas expenditure?
One more question, since I have a 95' model and never completed this maintenance, would I need to change all of those black hoses as well?? Your engine is so clean on your maxima. I wish mine was like that but my gaskets are slow leaking. Thanks!
Hey I just replace my gas gasket today and now my car turn off when I accelerate can you give some tips to check back again ?? Before that the car doesn’t do that
So i replaced it did everything put everything back together but now it starts and dies unless i press the gas idk i checked everything what could it be
I just reassembled everything & now whenever I go in reverse or put the car in gear & let it go forward, the engine/car begins vibrating, any ideas? Appreciate the assistance and the video either way.
Hi, Great Tutorial. Got a question, why you do not have any gasket on the intake port? In case there suppose to be one, do you happen to know what it is called. Thank you.
Its actually just called a swivel. Match it to your ratchet size if you have a 3/8" or 1/4" ratchet. We get most of our tool from Matco, Snap-on, or craftsmen
I have a 97 maxima that wont start if it does it cuts right back off I have had the fuel pump changed and the knock sensor and the mass air flow sensor along with the ignition switch and the relay oh yea and the valve cover gasket what else may and could be the problem
No gloves. Braver than I, lol. Cut myself too many times, cleaning a cut suuuuuucks. Good video though. I have one of these and it looks like its not fun to work on lol.
I have a 91 Nissan maxima n I brought all of the parts to got everything to do with my brakes done over n my brakes is still locking up on the left side someone help please asap
My 1995 Nissan Maxima GLE is leaking oil really bad from the rear valve cover gasket. My question is, do I need to mess around with the timing chain in order to replace the front valve cover gasket?
You do not need to do anything with the timing chain, however you will most likely have to remove the air intake, throttle body and upper plenum assembly.
Auto Parts Direct To You Ok sounds good, its cause my dad is telling me that the big leak is from the gasket on the bottom block of the engine and i don't know what that part is?
today i changed the valve cover gasket on my 1979 chevy c10 stepside truck and it took me 30 minutes flat from start to finish, thank you chevy for the good old days of well built machines that can be repaired without major headaches lol
Thanks for the video. Folks need to pay attention to the EGR gasket that falls inside the engine when you pull out the manifold. I did not realize it was missing until I read comments below after the fact and suffering a vacuum leak which led to the engine not idling. I recommend folks change the manifold and throttle gasket with new as well. This job was not a walk in the park! You need two persons to do it.

Good call. in fact most every intake manifold with an EGR system should have the carbon cleaned out of it when the opprotunity arises.
@Thomas Cronin what's the best way to clean that
@@joshwatson1502 Just use a screwdriver and a vacuum cleaner to chip and scrape away and remove the carbon build up blocking the opening.
You are the man my brother! i have the same car 1998 and its been sitting in the driveway. for a couple years........and i need also a new Valve cover gasket. thank you and i appreciate it.

looks like a nightmare just for a valve cover gasket
Thank you. I may attempt this soon as I am losing a significant amount of oil from the rear cover on a monthly basis.
awesome thanks for watching!
Your leak is not the rear valve cover gasket. You need to remove all the timing chains and the outter and most importantly the inner timing cover. The oil leak is caused by the bad o rings between the front of the engine block and the back of the inner timing cover.
I worked for Nissan and fixed many of these cars. Takes me about eight hours to do this repair.
I’m in the process of doing this and you make this look easier than it is. Thanks Nissan!
Ok thank you. I appreciate your response 👍
good job! But do not use too much silicone at the square corners since the excess will glob into the valve cover, maybe break off and clog an oil passage somewhere. Just enough is more than adequate.

We have a parts washer in our shop, so we used that. But you should be able to use any heavy duty degreaser to clean it up nicely.
Great tip about the grommets.

@@alex.millwood3406 yes ,it did. Valve cover gaskets fail over time. LOL this is an old post but I did learn over the years. I took my car to a shop a while ago and they repaired it. Now, I try to do most of the maintenance myself. Good luck.
I Changed the valve covers on my 2007 Nissan Murano with 193,000 miles and now it runs fine for 30 seconds than starts misfiring I got a P0300 code
What is the valve adjustment interval on these motors? I was thinking that could be done at the same time. Maybe do the front valve cover gasket also.
Great tutorial. If you wouldn't mind, could you list the tools you used for this in the description? Ratchet sizes, attachments etc....
I just started watching this video. Why was the valve cover gasket replaced?...my 98 v6 is leaking a few drops of oil lately on concrete driveway. there is much dried up oily residue around the valve cover seals and block. It also smells when you get out of the car possibly because the oil is heating up on the engine block and its giving off a burnt smell. I think I can handle this project. Thanks in advance.
The valve cover was leaking on this vehicle, It was leaking bad enough to be dripping on the rear exhaust manifold and causing the engine to smoke from underneath the hood. It was also leaking badly onto the ground.
having the same problem, no smoke but the smell is there
Yeah it slowly seeps out and ends up on exhaust manifold and the burning occurs and the smell.
That is the exact problem..any recommendations? Have to fix both front and back gaskets.. looking at the video and wanted to say thanks for the reply
Sure, recommendations would be to get good gaskets like FelPro. Also the smell may stay awhile even after replacing the gaskets as it has to burn off of the exhaust manifold. You can try cleaning it off but should catch all that runoff as it can damage a concrete driveway or garage. Also not good dumping oil on the ground anyway.
great video
I have a 2000 Infiniti I30 the timing chain broke was told it messed up my vowels in the head is this true or is it a non-in appearance engine
Will these valve cover gaskets fit on a VQ30DET? I'm dreading doing this job on my Cima; if it looks hard on this Maxima, my VQ30DET has even more things to remove to reach them. Looks like a full day job.
Thanks for the great video. How do you keep the metal EGR tube gasket in place during re-installation?
What is the name of the hose clamp you removed at 8:50? I broke the plastic piece at attaches to and need to replace it
Hey I'm changing the head gaskets on my 2001 Nissan maxima is the timing hard to set back
Getting the timing chain aligned properly is critical, I would suggest just following the repair manual to a 'T' when resetting all the timing components. It can be a little tricky and may take more than one try to get it correct. Just double and triple check everything as you go.
Nice and easy
good job
Hello I have an 1997 Infiniti I30 and it’s smoking from behind the manifold but no smoke coming from the exhaust. Any clues?
jairoh alford it’s probably the rear valve cover gasket that’s leaking on to the exhaust manifold. Burning off causing the smoke. My 96 is doing the same. I will be doing this repair myself and save some money.
Hey, I have a 95' Maxima SE. Okay... so what benefits will I receive from changing these gaskets?? Will the engine sound better after doing this? Will I get better performance from my engine? I just changed the PCV valve a few weeks ago, but I should of waited because I see that while taking the top intake manifold off you can easily access a lot of the needed periodic maintenance areas. But great detailed video man!!
When the timing Chain break doesn't mess up your vows in the head to make it misfire don't want to spend a lot of money and it not work please enlighten me on this matter thank you and God bless
Thanks. Doing it today.
Hi there,, I'm about to do this to mine, now do you or did you have to change the intake manifold gasket as well. I brought a gasket kit but never had the intake gasket included thanks.
Ash Jod yes you would want to get an intake gasket as the intake will need to be removed to get the rear valve cover off, it’s not too bad a job really, thanks for watching and good luck
@@APDTY yeah that's what I thought,, thank you very much for the feedback..
Which could be the function for the two last hoses you disconnected before taking off the intake manifold. It seems they flush hot water to the base of the intake manifold. I´ve just bought a car like this and it has broken a pipe where must to be connected one of this hoses. Do you think this problem could cause a higher gas expenditure?
it helps warm the throttle body butterfly, in sub-zero climates it might freeze and stick.
You should have listed what tools were needed to complete this job.
looks easier than the camry v6 engine
How long did it take you to do this? I am thinking about doing it myself and would liketo know the approximate time.
One more question, since I have a 95' model and never completed this maintenance, would I need to change all of those black hoses as well?? Your engine is so clean on your maxima. I wish mine was like that but my gaskets are slow leaking. Thanks!
My moms 99 Maxima manifold cover leaks and just wondering if it's possible to just try tightening the bolts some ?
😱😱 u mean i gotta do all dat
Deezie Jones exactly what I’m saying ...
Hi sr I have a cuestion I have a 97 nissan maxima gxe.. why smell fuel inside my car . Any help??
Hey I just replace my gas gasket today and now my car turn off when I accelerate can you give some tips to check back again ??
Before that the car doesn’t do that
So i replaced it did everything put everything back together but now it starts and dies unless i press the gas idk i checked everything what could it be
Good job bro
I need both front & back replacement on my gen 4 a32 vq30, how long would it take a qualified mechanic to complete the job???
I just reassembled everything & now whenever I go in reverse or put the car in gear & let it go forward, the engine/car begins vibrating, any ideas? Appreciate the assistance and the video either way.
What did you use to clean all of the oil of the valve cover?
Hi, Great Tutorial. Got a question, why you do not have any gasket on the intake port? In case there suppose to be one, do you happen to know what it is called. Thank you.
Where did you get those red angled pliers you used to take the hoses off????
Hi i wanna know what brand of cleaner you used to clean the oil slug
What is the torque specs on the intake manifold bolts
Excellent video can you tell me what type of swivel tool you had on your ratchet I would like to get one.
Its actually just called a swivel. Match it to your ratchet size if you have a 3/8" or 1/4" ratchet. We get most of our tool from Matco, Snap-on, or craftsmen
Thanks you been a great help
Do 1999 nissan maximas have the same valve cover gaskets as a 2000 nissan maxima v6 3.0
Not the same but very similar, the 2000-2001 3.0L takes this kit: amzn.to/2HVsPrF
I have a 97 maxima that wont start if it does it cuts right back off I have had the fuel pump changed and the knock sensor and the mass air flow sensor along with the ignition switch and the relay oh yea and the valve cover gasket what else may and could be the problem
What kind of wrench is that? The one that bent and you were able to spin the bolts off with it?
Its a flex socket/wrench or pivoting socket/wrench
No gloves. Braver than I, lol. Cut myself too many times, cleaning a cut suuuuuucks. Good video though. I have one of these and it looks like its not fun to work on lol.
I have a 91 Nissan maxima n I brought all of the parts to got everything to do with my brakes done over n my brakes is still locking up on the left side someone help please asap
Make sure to check the calipers and brake hoses. You may have a caliper that is locking up or a brake hose failing internally.
My 1995 Nissan Maxima GLE is leaking oil really bad from the rear valve cover gasket. My question is, do I need to mess around with the timing chain in order to replace the front valve cover gasket?
You do not need to do anything with the timing chain, however you will most likely have to remove the air intake, throttle body and upper plenum assembly.
Auto Parts Direct To You Ok sounds good, its cause my dad is telling me that the big leak is from the gasket on the bottom block of the engine and i don't know what that part is?
Can you show how to replace the egr tube on a 98 maxima
yeas as soon as we get this car in
