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.

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.

'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!

I’m in the process of doing this and you make this look easier than it is. Thanks Nissan!

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

looks like a nightmare just for a valve cover gasket

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.

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.

Ok thank you. I appreciate your response 👍

Nice video! But you should've replaced the PCV valve while you were in there :p

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.

Beautiful demonstration..........

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 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.

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.

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.

Thanks for your knowledge

You make it look so easy haha

Thanks for the great video. How do you keep the metal EGR tube gasket in place during re-installation?

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.

Good job bro

Haha you are so correct, I have melted a wrench in the past too,, old habbits (even bad ones) can be hard to break though. :)

Thanks. Doing it today.

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.

EXELENTE...GRACIAS BROO

He put it back together with a completely clogged EGR TUBE

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 :)

Nice and easy good job

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.

i have 1 thing to say well maybe 2 or 3 lol u are the best this help me out a lot

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.

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!

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.

@APDTY

5 жыл бұрын

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.

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!!

If the oil leak persists, remove the outter and inner timing covers and replace the Orings on the front of the block.

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.

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.

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.

Where did you get those red angled pliers you used to take the hoses off????

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

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?

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. ??

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. :-(

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

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

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.

Hi i wanna know what brand of cleaner you used to clean the oil slug

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

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.

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.
