VERY IMPORTANT MANUAL DOES NOT MENTION- DESTROY ENGINE
make sure camshaft dowel pins do not get pushed in when installing camshafts
my timing chain sprockets went in too easy, turns out dowel pins were pushed in and gouges the head and cracked the camshafts when i went to turn the crankshaft pulley to check timing.
if you feel any resistance on crankshaft turning engine do not put any pressure.
check camshaft dowel pins make sure they are not pushed in towards the smooth surface, engine turned 90 degrees then stopped, i thought the chain might be snagged, added more pressure now i need new cams and head might fall apart after few miles if i dont get a new one
i definitely appreciate you adding that feedback in, as I was still trying to find an answer for you about you not being able to rotate the crank. Got this pinned incase anyone else runs into the same thing!
@@HectorTTalks thanks, luckily i got pick and pull cams so i get another shot but might have to take head back to machine shop and let em rework the buckets, not sure if i trust myself and my $10 feeler gauge and kinda vague instructions and no second opinions, im a DIY'er not very car experienced
was so dumb...gotta hold or make sure the sprockets dont move when you tighten down, i thought it was gonna be easiest part just slide them in the grove but must have slipped and i didnt know to hold em in place
i havnt done it yet but i assume this is why guys put vice grips on the camshaft i didnt understand why they were doing it, wasnt explained well in video's ive watched
@@HectorTTalks I just did my head gasket. Thank you. A few things I learnt in addition to this video- JMO from a novice.
Turn your wheels hard right before starting.
Top dead center doesn’t matter - as the gears are marked relative to each other, and gears to the timing chain, (I also marked lower pully to engine) any position is restored and a point non TDC reduces risk of valves hitting the piston with a fool in charge :). Some wall height also allows solvent to pool and clean deposits from the top of the piston.
Check your valve clearance prior to starting. A couple of egg cartons held caps in a safe/organized manner for reinstall to optimal position
Remove the power steering fluid container, radiator reservoir and the radiator/fan assembly. It’s far easier.
There is a hidden bolt connecting the timing chain housing to the valve block, it’s hidden within a recess in the lower middle.
Have some help available whilst you remove serpentine belt tension, or a 6mm bolt (so I’m told) to lock the serpentine belt tensioner into position.
Hold the timing chain up at 3 points to the timing chain housing with cable ties. One in the middle, and then another as each cam gears comes off. This ensures the chain cannot slip where you cannot see it on the lower gear.
Use a pin on the timing chain tensioner. I removed it successfully, but lost the spring and cap into the lower section when trying to install. Fished out with a magnet attached to the end of a hex wrench placed within a rubber glove, save the delay, find a pin. (very small screwdriver, hex wrench etc).
Great vid. THANK YOU.
@@truthaus6840 those are definitely great tips, thank you!!!
This the most relatable auto repair video ever. Thank you big brodie.
You're welcome!
So dope how u added the the tools that alone was a big help Im a Aspiring machanic and love the lil details like that keep it up its awesone
You're very welcome, glad it was helpful!
The third cylinder is where the coolant was getting into you can tell by that being the cleanest piston out of them
My days of engine repairs is over because of age, but this is making my back hurt just watching it. I used to enjoy this kind of work, but ya know..The old body just doesn't want to keep up anymore.
We're all going to get that way someday and even if not one of these days we're going to die and stand before God Almighty so it's best to get right with God!
That's what the CROSS of Jesus Christ is all about. Read John 3 3 7 unless a man is born again, he shall not see the kingdom of God.
I definitely learned a lot about my car thank you
My pleasure!
Great work dude, very helpful! I'm about to start one myself and needed to know what I was getting in to.
You're very welcome!
Today car didn't start checked everything is ok except ive seen a pool of water aftervremoving spark plugs in 3 cylinders 😢😢😢😢😢😢 and its done 2 years back only ,ill try to do it tomorrow ,my bigger concern is the intake manifold the most difficult part .
Awesome vid man. Somebody once told me they changed the head gask. on their nission altima w/o engine crane or anything but normal tools I I said they were full of shit. I guess I was wrong
Where there's a will, there's a way!
I guess that makes you full of shit instead😆
Yo hector brotherman I'm asking, why is the #1 n #3 ignition coils hard to get out their like stuck n the top part of the coils just keep coming off bt #2 n#4 came out the way they should bt having a hard time with #1 n #3 bra-tha hope u can help me out bra-tha
Good video! I recommend zip tying the timing chain to the timing cover bracket after marking it.
Thanks, definitely a good tip!
Good ahit
The timing chain itself doesn't need to be in a certain tooth on the cams and crank, but the cams and crank need to lineup with themselves.
Yo, hector I've been watching your awesome video 4 changing the head gasket n (boy) u really explain it all cool n in a way to where u would understand cause I'm not a mechanic bt I know some things about fixing a ride from whatching other people n especially your awesome video's brother man OH, is it ok to call u brotherman, I'm sorry calling u like that bt I like to call u that cause when I see your video's it's like my real brotherman talking n showing me how to do r make me understand how to fix my ride, cause I bought this 2005 Nissan Altima 2.5L Engine 4 cylinder from a mechanic here in, Oh,,, I'm sorry didn't even tell u where I'm from,not afraid r scare to tell u where I'm from bt I am from ZUNI,N.M. n like I said u are really a good instructor n (boy) I really like this head gasket videon hope u don't calling u brotherman bt I really like u, feel's like I know u bt I wish I really new u bt with all my THANK'S -N-GOOD BLESSING'S,,,like to see more of your awesome good understanding video's. Cause I ain't no mechanic bt know some things bt with your video's it really makes me understand on how to fix my baby Nissan Altima bt I'll let u know on how I do when I'm done n it runs I know it'll run well gnight from Zuni,N.M. teach me more I'll appreciate it THANK-U ONCE AGAIN!!!!!!!!!!!
Thank you! I really appreciate knowing that my videos are helpful! And yes definitely let me know how it turns out!
@@HectorTTalks ok right on I'll keep in touch
Taking a head off of a vehicle the torque sequence doesn't matter. But I love the video how you took your time to show people what you're doing, and can understand much better!
Cylinder heads are very prone to warping and bending, especially if you just loosen the bolts whichever way you want. He was right to loosen then according to the torque sequence
Actually it does matter.
It does matter. Start from both ends and work towards the center evenly. Go through and break then all loose until they crack, + 1/4 turn. Then go back again and fully loosen them.
Tighten new bolts back in 3 stages when installing.
Put head gasket but leading a little oil on end next to timing cover
Hmm, I would have it checked to make sure there isn't any small cracks or warping. Sometimes small shops can do this and aren't expensive to have it done
@@HectorTTalks you think I don't have the bolts tie even
@@LendwoodHilliard could be possible. What torque pattern did you do?
@@HectorTTalks the one like you got don't think tie do I need to change gasket
@@LendwoodHilliard I would recommend having it checked first for cracks or warping first before going through replacing the gasket again
Did you use special tools to remove the camshaft?
@@MoneyRunCam so I had a 28mm open ended wrench to hold the camshafts from spinning while I loosened the bolts on the cam gears. For that I had a breaker bar so it had leverage to make it easier to break the gear bolts loose. You could use an impact gun, I just didn't. Once you get the gears off, then you take off the camshaft bearing caps and the cams lift right out
You could have removed the head with the inlet manifold. Saves time.
Yo, hector can I see the video about finding the TDC on a 2005 Nissan Altima2.5L 4 cylinder engine
Hi there Hector, this is Lin, I don't know if u still remember about the chain tensioner 4 the timing chain on my 2005 Nissan Altima 2.5L 4 cylinder engine, cause when I loosen it remember I said it fell in, so I'm trying to look 4 it bt can not see it, so where do u think it went to r like u said that I have to take the bottom cover off u said, so that's why I'm asking what I should do
Oh then yes you may need to drain the oil to then remove the oil pan to get it out. Now if the tensioner is not in the oil pan, it may have gotten stuck on the timing chain or in the chain cover. You might be able to turn the crank pulley with a wrench to move the chain and knock it down out of there.
@@HectorTTalks oh ok I'll try that
@@HectorTTalks Hi there Hector, so is it hard to take off the oil pan r am I also gonna need a filter 4 the oil pan r is that just 4 the transmission
@@linshebola8080 there's no oil pan filter. You may need a new gasket which you can use RTV for, but there's no filter
@@HectorTTalks oh ok,bt do they sell oil gaskets r like u said just use RTV if so I'll go ahead n use the RTV cause I have that,bt THANK-U
good video.
Thank you!
This video is very self explanatory and I followed every step for my engine Wich is the same one but I came across two problem one is the timing belt second I want to tell anybody who's doing the timing belt I putba pin on the tensioner and it didn't hold and it popped out and fell inside the bottom belt cove please don't do the same mistake it's a tricky process is not that simple do your homework on chain and tensioner
Was that to find the TDC?
Yeah I like how it’s so professional I like how you explain so technical you’re good man
Thank you for taking the time to make these videos. I have a 2005 Altima 2.5 also. It keeps throwing the code for random misfire so I changed the spark plugs and all 4 coils. After a few days driving it my plugs foul out and it won’t start. My antifreeze keeps disappearing but there’s no water in my oil, no oil in my water and it doesn’t smoke like when an engine is trying to burn water/ antifreeze from a blown head gasket. So do you think it’s got a blown head gasket or could something else be causing this?
Also, when it does start up, it runs and idles smoothly like it’s got no problems at all but the service light is on.
@@randallfields2819 thats kinda weird that its idling fine even though you were getting misfires, which could be from numerous things like a timing chain, sensor issue or even MAP issue. I would check those to make sure everything is in order. As for the leak, try putting in that UV leak detector fluid because it may be leaking from somewhere other than the head gasket and you'll be able to find it with the fluid. Also, when you replaced the spark plugs and coils, did they have oil on them?
Hector T Talks I think they had a little oil on them. It was hard to tell if it was oil or the plug turning black from firing the spark plug. I appreciate the help man. I’ll try your suggestions.
@@randallfields2819 No problem! If you can, check them again to see if theres any oil on the spark plugs or coils because unfortunately the tube seals for the 2.5 engine suck and they leak after a while but you have to get a whole new valve cover because the tube seals are built into it and aren't serviceable themselves.
Hi Randall, Mine was doing close to the same thing. It was throwing a code for #3 cylinder misfire. I put a camera down the spark plug hole and found water. Never did foul a spark plug. Another symptom was I lost my heat at idle indicating that there was air in the system from the exhaust blow by due to the bad head gasket. I tried Barrs head gasket sealer. Only slowed it down.
So do I really have take the timing chain off cause on the other comment I saw said he twist tied the chain on the housing of the cam r the timing chain housing so that's what I did n also my upper intake got a scratch on it so can I sand it down r can I go ahead n put on RTV on it also do I use that copper spray on the gaskets
Got some Bars Head Seal and I put it in yesterday and its already stopped the overheating and will continue to seal anything from radiator leaks to intake gasket leaks. It covers a ton of stuff and is a permanent fix according to what the label says. Its the more expensive formula that has carbon fiber in it to really give a strong seal. Cost 50$ and takes a solid day to do it properly without rushing the process. I'm pretty stoked on not having to slave away under the hood or cash out big on repairs. Hopefully the next year or more will be solid. You can keep it running in the coolant too and it will continue to do its job. Hope this helps you or someone else.
I knew a few people that tried that for different cars but had mixed results. Some it lasted the rest of the time they had the car, some it didn't last long. I think when done properly, it's a good fix so hopefully this one time is all you need! But yes, definitely a good alternative to replacing the gasket!
I got a 2006 Nissan Altima. White smoke from exhaust. Does bars head fix the head gasket?
@@samrawsteen1326 I never recommend Bars because I've tested their products for other sealers and they don't work. For a liquid fix for the head gasket, I always recommend the Blue Devil sealer because I've helped people to use it on different cars and while the results vary per car and efforts, it's still been really good!
@@samrawsteen1326 how often are you driving your car?
@@TheWayEverlasting a
Ok mission accomplished headgasket, timing chain ,giudes replacement 👌
Hey awesome video thanks! Would yo u recommend me trying with a headgasket stop leak? Before going throught it all? I have mild signs not even have water on oil or vice versa, but I do have water comming through.
I know people that have tried the leak stop fluids and they had success with it lasting for a few years so definitely worth a shot!
Got to give a shout out to you all the way from Trinidad. Great DIY video.. keep it up
Thank you!
Hey Hector, I also have a Nissan Altima 2005 and it’s been throwing a lot of white smoke specially when I’m gone take off on the freeway. Then it randomly turns off and it doesn’t want to turn back on. Does this mean it needs a head gasket change ?
That is definitely some of the symptoms. How's the temperature gauge, does it get hot before turning off? Also, when the car is off, take of the oil cap on top of the engine and check to see if the oil is a lighter brown.
@@HectorTTalks yess, it starts overheating and then turns off😭. Is it expensive to get this repair?
@@SweetKillah97 ah ok. Another sign would be after it over heats, when you fill the radiator with coolant or water, if it over heats again within a day or two and you gotta fill up the radiator again. Now, to get a head gasket replaced is pretty costly. I've seen some shops or mobile mechanics that would charge $1500, and other shops I've seen up to $2500 to do it, just depends where you go and if it's worth it to you at that point.
@@SweetKillah97 but I would definitely have someone check it out first to diagnose that, because on the flip side, it could just be the water pump or the thermostat, which is way less expensive to repair
@@HectorTTalks great! Thank you so much ! ☺️
The manual has some confusing steps. This video made it very clear on how to remove the C-head
Aren’t u supposed to keep chain held up the whole time so u don’t jump a tooth on crank ?
4got pin in, take off the chain tensioner then the timing chain then the gears right cause I'm doing the head gasket on a 2005 Nissan altima 2.5L 4 cylinder
Correct!
Hector, so just torque the gear's at 95ft lbs. Then no more?
Thanks man tough job will start to do this tomorrow cause I have milky oil, also want to ask do you have to remove front engine mount and passenger engine mount??
For this engine, didn't need to remove any mounts!
@@HectorTTalks I'am planning to do it tommorow but the problem is that I don't have angel wrench, I've ordered that for tourquing oem screws
And by the way how do you remove screws of the cam sprocket did you use torch and holding cam with open wrench 24 mm then using torque wrench on the screw of the cam sprocket
So you never actually want to use a torque wrench to loosen bolts. I did use a 24mm open wrench on the cam lobes to hold them still. Now for the bolts on the gears, i actually used a breaker bar with a hollow bar that i have that fit over the breaker bar, to add more leverage to it since it was just me holding both wrenches and didnt have anyone to help.
@@HectorTTalks thanks great tip yep what I mean breaker bar
I've found on ebay a set of all gasket and screws with 1 year warranty and I can buy oem head gasket which is better cause I think you don't have to replace all gasket and in case I bought that kit iam afraid that aftermarket head gasket is not that good on ebay 🤔 just thinking
Me personally, i did get a gasket kit and the reason why is because it came with a multi layered steel head gasket which is pretty much what the oem one is plus all of the other gaskets. Now, with my car all of the gaskets were original and it had 145k miles on it so the gaskets were no good to reuse. Not sure if thats the case with yours but it might be better to get a gasket kit just incase if you need them.
I know this video is two years old I haven’t seen anybody mention this in the comments. This car has two thermostats did you change the other one?
Great question! At the time of the video I only had the rear thermostat, so I had to wait a few days later for the front thermostat to come in, but yes essentially both were changed to make sure that there were no issues going forward with the old ones.
Hey I just came across your work video. It’s been awhile. You still have vehicle and how did it work out. Thank you
Hey hey, welcome back again lol. After the head gasket replacement it's been running pretty good. I used it for Lyft and grocery deliveries and right now my friend borrowed it to go up to Jacksonville FL which is a 2-3 hour drive which I'm hoping he brings it back in one piece. The only issue I had was the thread on the cylinder head for the valve cover. It stripped on a few bolts so I used RTV but once my friend comes back down then I'll have that re-threaded
Yes so I would have to disagree with you there at 16:46. That is just dead wrong and I know a thing or two. I have been in the automotive industry for a sum of lets just say this... I was using socket wrenches when you were still in diapers hahaha
Congratulations
What special tools are required for this? I have basic wrenches and sockets, but don't have special torx or allen wrenches.
In order to be successful in performing the gasket replacement you will need specialized tools and equipment. In the video description is a list(with links) for all of the tools that i used!
Yo, brotherman I'm putting her back together bt asking where do I put those small round cylinder's n the O 'rings especially those big O'rings, there's red n black small O'rings n different size bigger in black O'rings
I don't remember using big O rings for the gaskets but the small ones, are they metal or rubber?
@@HectorTTalks rubber black n red then the big ones r black bt the small round cylinder's r m,metal n in like copper color bt I put 2 of the red ones in the engine block in the left n right corner's that's towards the front bt I haven't put the bolts in yet cause it started to rain again so I just stopped n also ran out of daylight so thought I'd ask so I'll know that I'm doing it right like u brotherman w'a'no's
@@linshebola8080 I know the metal ones go between the block and head cylinder, basically around the edge right in the indents, which are also cut out from the head gasket
@@HectorTTalks so do I need to change the O'rings
@@HectorTTalks oh,n the torque on the cylinder head after I loosen the bolts which 1 do I do the 26 r 32lbs
Hi sir! You are a best ever for teaching us more tricks. Please tell me how much torque is required or you use to torque the cylinder head bolts?
Hey, for the torque specs, in my assembly video which is part 2 to this one, I explain the torque procedure
Im a total idiot at car mechanic but i have access to tools and the will to try to do it myself, so my question is does this also applies to a Nissan Altima 2003 2.5L? From the look of it the engines look pretty similar, is there anything different i should look out for? great video btw ^^
Thank you! Now from what i remember there was one or two slight differences with the 2003 engine but the overall processes should be relatively the same.
Great job. Wouldn't know it was the first head removal you'd done. Really helpful
Thank you!!
Hector great video man! I’m looking at this and I’m like how the hell am I going to do this. My wife’s Nissan Altima 2005 is blowing Exhaust out of the front of the engine. I’m guessing here it’s a gasket. I was out in it last night and I think that’s when it took a crap! It’s been burning oil a lot. The Exhaust is getting in the car while I was driving last night. When I push down on the Excelerator pedal you can hear the hissing from the engine. Does this sound or seem like a head gasket? I’m really not sure. If you don’t know it’s fine. I’m going to have someone look at it.
Thanks Brother!
Your video is great!
Sounds like a definite leak, fortunately its easier than the head gasket. I would start with the exhaust gasket first then make your way down the exhaust to find any other possible leaks.
11 minutes of bullshit talk before the first bolt is removed!
Hi friend how are you, by the way, now iam driving 50 mph or should I drive slower or is it normal to drive 65 mph?? Don't know when I can drive normally??
Well there's really no break in needed for the new headgasket.
@@HectorTTalks thanks man 👍👍👍🌹
You're welcome!!!
@@HectorTTalks now my main issue is idle relearn it kills me trying to do it many times but no luck
Will try tommorow afternoon cause mostly I gave up on this it kills me even ive removed 2 coils idle reached about 800 idle relearn done once switch car off its bouncing (rpm) between one and two
Trying many time everyday
Switch car off 10 sec
Then on accessory 3 sec
Press accelerator 5 times within 5 seconds
Don't press accelerator for 7 seconds
Press accelerator and check engine light start blinking and once it's stable slightly take of your foot from accelerator and start the engine
So whats wrong on that??
@@Sroor2023 thats definitely the correct procedure but its weird that its not working. I would try disconnecting the battery and put the headlights on for 30 seconds(they might flickwr on for a split second then turn off) this will completely discharge everything in the car and can help reset the ECU. Then connect the battery and try to let it idle as is for a few minutes to see if you're able to get it to idle temp then turn it off and try the process again.
The B16 is on the 07-12 right any difference I should know before tackling this
On the B16 version the main differences are different fitting cylinder head and valve cover, different side engine mount and intake manifold. Same basic principle and tightening patterns but slightly different procedure such as the removal of the top side engine mount(in most cars with the b16 engine, the side mount is bolted towards the top of the engine and needs to be removed before being able to remove the valve cover and cylinder head since its blocking them)
Is the gasket oem , the one you originality pulled off?
To be honest I'm not sure. The previous owner never had it worked on but I have no idea about maintenance with any other previous owner.
What issues you had with the car that indicated the head gasket needed replacing, did you have trouble starting, was it smoking, did you have any issues starting again after turning off for 10-20 minutes?
The biggest sign that caught my attention was that it would overheat. It started and would run but once it was overheating I would leave it off for about 10-15 mins for it to cool before adding anything to the radiator (since the coolant was leaking through the gasket) and running it.
Hi there bra-tha I wanted to do the colored links to do the TDC bt it's getting windy bt probably just set up the plastic trap I got as not 4 the sand get into the engine n since it's not that cold, so I crank it to get the notches at the right place then take off the tensioner n set the colored links at the right place
Head gaskets 50 bucks a new engine is 1200 installed I know which one I’m gna do thanks for this video it was very helpful
Indeed! Glad it was helpful for you!
$1200 maybe used engine not new one
Did you have to re do the timing ?
I did as it was just slightly off by one notch
Is it necessary to take of the intake manifold ? Is it possible to take of the head with the manifold still on it ?
You can leave it attached but there's other components that are connected to the intake manifold that kind of hold it in place such as the fuel rail and some other clips behind it, which would need to be removed. Plus, removing it allows you to be able to put on a new gasket if its worn.
Yea your right thanks dude good job on the video ill be doing mines this weekend
@@diegovargas2846 You're welcome! And hopefully it goes well for you!
Dude lost me when he said we wanna gonna hand sand the head😂
How long have you owned the 2005 altima? I have the same year altima and it has 220,000km on the original timing chain and head gasket. Ive replaced the crank and camshaft sensors a year ago. The car is idling rough at red lights as well sometimes troube starting. I'm wondering if my chain is stretched and throwing off the sensors? Any thoughts and would a new chain help with starting it?
Thats a good question because mine has started doing the same thing a little while ago. Now i know the tube seals im my valve cover are leaking oil because thats a very common problem with the 4 cylinder, especially with aftermarket covers, so i would check that. Now if you're getting random misfires as well as a rough idle i would check the sensors or replace them since they're kinda cheap and if it then continues check the chain. I know i need to replace my timing chain because it's still the original one and i had it aligned perfectly when i did the head gasket replacement so for mine to be off with the idle i know besides the leak, my chain is no good. Also check your catalytic converter and O2 sensor. If its realy clogged it could idle rough because the O2 sensor isn't sending the proper information.
@@HectorTTalks thanks for the reply, its strange regarding the trouble starting my car at times. The battery is 3 years old as well the starter was replaced 3 years ago. Checking the battery with a voltmeter with a load on the car (20 secs of leaving the car in the on position prior to turning the car over). It went from 12.25 V to 11.30 V before turning it over. Then it dropped it 10.3 when cranking over. I taked to a Nissan mechanic and he said that it still could be the starter as they don't make good parts these day. Both were still under 3 year warranty so i replaced both tonight. Car started great. So in total I have a 1 year old camshaft sensor and a new crank shaft sensor as well new battery and starter. As for the rough idling i wonder if changing the O2 sensor as well catalytic manifold would really help? Do you think? They've never been replaced, or i wonder if it's more possible I've got a leak of oil running in the sparkplugs from the main cam valve cover.......? Thoughts?
I think it's that thin slot between the cylinders, that causes it to leak. The one I'm working on doesn't get coolant in the oil. With the cooling system void of pressure, just cranking it without starting, would cause pressure in the cooling system.
If you have a butane torch you can lightly preheat the area around the bolt head and avoid stripping. Or shock the bolt head with a copper hammer to avoid mushrooming the head. About to do my first nissan head so a much needed view of the process.
Great advice, thank you!
The head comes off with intake attached no need to take it all off in the engine
True, but it's about 20lbs lighter when you take off the intake lol
@@HectorTTalks but it's easier to remove the intake.off the car
Thank you for the detail too though!!! Quite helpful!
Yo bra-tha can I crank it with out the tensioner on cause can't get a hold of the spring bra-tha, I did get the oil pan off bt there was nothing in the pan n why is it that my oil was all black
No you can't crank it without a tensioner on the timing chain. If it's not down there you might need to get another one and then turn the crankshaft by hand with a new tensioner in place so that if it's stuck on the chain and timing cover, turning it by hand should get it out and then you can crank the engine. As for the oil, there may have been old oil circulating around or still sitting in the oil pan.
@@HectorTTalks so like the whole new tensioner, I can't buy the spring by it's self n what's gonna happen if I crank it without the tensioner on
@@linshebola5465 I did a quick search online but it doesn't seem like there's places that sell just the spring, but you could go to a local junk yard and take off the tensioner if they have an Altima in stock. As for trying to start the car without it, it's not gonna run good at all if it even turns on. Without the tensioner the chain will be loosely trying to spin the cams with the crankshaft and will eventually fall off the cam gears and would cause some damage to the engine.
@@HectorTTalks oh I didn't mean crank by turning it on I meant by hand bro bt ok bra-tha see what I can do wa'no's bra-tha
How many miles are on this?
good video, i had some questions about why you have it machined. and if you're just replacing the gasket, how could you have determined if the head had an issue itself. would you see physical cracks? anything you can tell me about the process of machining the head would be appreciated. also from a video standpoint, i would say maybe a quick blurb about all the tools you used or will use would be useful. overall show some confidence bud you're killing it
Thanks for the advice! Now the reason I had it machined was because they did check for cracks since some cracks can be too small to see by eye and I wanted to make sure it had a clean, smooth surface to mate the gasket onto by having it machined, which cuts away a very tiny layer from the bottom of it. Now, they could have cleaned the whole head and checked the valves and springs at the shop too but that would have took them longer and cost more which I didn't have the money nor time for them to do that when I had it done. As for the tools, I try to mention them in the video, but I'm also gonna go back and list all the tools and equipment used in the description!
Your a beast you know a lil somethkng just come replace mine damnit lol🤣🤣🤣
Lol if i could i would!
If that head gasket isn't blown something is cracked, if oil is getting in the cooling system
Dude this video is awesome!
Thank you!
So after I put the pin in then I take the timing chain off n take off the gears n get into the cams right
man that timing chain needs replacing
it's not too bad but yes, as soon as I'm able to i'll need to replace it
How much do this cost
The one I'm working on had no real sign that it was the head gasket, other than it didn't want to go over 3.5K RPM's. Sometimes it would go higher, sometimes only 3K. No water in the oil. The exhaust didn't smell like coolant. After driving it into the driveway, it actually ran smooth, but I pull the plugs out and the heads are all wet still. Today, before I started working on it, it did get up to 4.5K RPM's. The plugs looked dry, unlike the other day troubleshooting, they were wet after driving it into the driveway.
So oil on the spark plugs and or coils could actually be from the tube rings which are built into the valve cover, which you would have to replace. Now for the RPM issue, that's usually a sensor problem. Scan to see if it's giving any codes and check out the mas air flow sensor. Sometimes if it's faulty or having issues, it'll restrict power
@@HectorTTalksThere were no codes for the MAF. I'm thinking the RPM problem may just be from low compression? Or the catalytic converter is restrictive. I did clean it out. When I started cleaning it, only one small spit of light came through. After cleaning it, there was a lot of light coming through, but you can see sections where it looks like a crack and it's fused. Some spot spots of stuff in some holes, but mostly clear.
@@shark70007000 speaking about that check out your O2 sensor. If the cat was clogged that built up may have gotten into the sensor. And you can definitely run a compression test, they usually rent them at AutoZone
I have an Owen bus. On the heat issue, I changed the thermostat and fan, sprayed water, sprayed the thermostat, wiped the head, and it was still hot.
Owen bus?
Would you be able to do this on a 2014 Nissan Altima by any chance 😭
My neice has a 2004 Nissan Altima. The head gasket just blew. You said the engines run hot so the gaskets blow. That let her off the hook for being dumb & driving the car a long way with no water in the radiator. Wat hing tbis.. it made me decide to junk the car.. I've paid for a whole new suspension tires & so on. Now this.. probably cost more than the value of the car I'm guessing
Well definitely driving without coolant will blow the head gasket and could damage the engine. Now from what I've heard from other people, going to a shop can cost upwards of about $1200 to $1500 to replace the headgasket(mostly for labor) which at that price you can find another car. My suggestion if she's not so good with maintaining cars would be for her to get a Honda. They can take a beating and last.
I’m working on one right now, after getting all the bolts out how did you manage to take of the head. It seems glued on good.
I ended up hitting it with a weighted soft mallet on the corners to loosen it
Yo, hector can I see the video about finding the TDC on a 2005 Nissan Altima2.5L 4 cylinder engine
I didn't make one specifically for that, but there's definitely videos and guides out there that can help you find the TDC.
@@HectorTTalks oh, ok bt is it like getting the two holes on the gears center on top n the two lines meet together in the middle like that cause I saw that one video on Vtech something bt is it like that is that TDC
What u think about, if you add water to the radiator, it starts coming out of the exhaust tail pipe? Blown head gasket?
Little drops of water coming from the tail pipe is a actually normal unless you have a lot of water pouring out then that's bad lol
The real problem with using water instead of coolant is that it can cause internal rusting and since summer is right around the corner, it'll heat up and naturally evaporate or cause leaks in the cooling system
Yo, hector I loosen the bolts on the chain tensioner n I kinda turned the tensioner n the spring n well all of it fell down inside the cam n now I just worried I can take the bottom off huh well it's just the spring n the shaft thing bt I have tensioner n I have a magnet thingie I was gonna try n get them back with it do u think that would work
Well, if it got caught by the chain in the timing cover you might be able to fish it out with an extendable magnet, if not you'll need to take off the bottom cover or oil pan to get them out. Would not recommend leaving them as that will cause damage
@@HectorTTalks yeah that's what I was thinking of doing n yeah I do got an extent able magnet oh ok THANK'S so much u are quite a good help if I have anymore things to ask I text u 4 help gnight
My spring fell down there too. Got the cylinder out with magnet but not spring. Was anyone able to just pull oil pan and get it. Is there even a way for it to fall to pan?
This is no job for an amateur. Watching this video and trying to just “go for it” will not work. You have be advised. Atleast have professional guidance if you wanna do it yourself. Video doesn’t show aligning and testing values, timing the engine etc. those are skill tasks , not something you can do again if you mess it up
This video is just simply a disassembly video for demonstrative purposes and not for anything else such as setting the timing, testing anything, etc.
😂you’re a clown if you think a head gasket replacement is a “pro” task besides most states don’t require schooling and schooling doesn’t make you a pro it makes you informed but that don’t mean experience can’t trump your info (see what I did there 😂) anyways stop trying to hoe ppl
Does PE6 Nissan engine and PF Nissan engine are the same rare oil seal diameter?
Sorry I'm not sure, I haven't worked on those engines yet. I mostly work on the KA's, QR's and VQ's.
Yo bra-tha u get my text bro
Yo, Hector is their any other bolts to loosen cause I've already took off all the bolts off the cylinder head bt something is like still holding it on the timing chain side bt it has gotten loose bt that's the only side that's holding it bt I'll try jiggle-in it
Check to make sure the timing cover isn't still connected. You have to reach down quite a bit to get all the connector bolts
@@HectorTTalks yo, bro I got it yesterday just in time B4 I ran out of day light. It was the middle bolt on the cam cover which didn't show bt I finally got it, first it was the two bolts on the bracket on the bottom of the intake that was holding it that didn't show bt boy I finally got it,yes now I can see how it looks bt going into gtown n so do I need the cooper spray n do I really need to buy new bolts 4 the cylinder head
@@linshebola8080 yes you have to get new cylinder head bolts because the current ones will snap when you try to re-torque them and the copper spray is optional, but I like to use it to make sure it has a good seal
Yo, Hector how do I clean inside the cylinders cause their just all charged up n those small round metal circles do they go in the cylinder head n can I re-thread the engine block 4 the new cylinder head bolts cause my step daughter's husband works on ride's n he said that I can do that so that it'll get good n tight he said n he has those things to do that he said,cause I finally got the cylinder head off n now about too see if it's warped, oh n I didn't put it on the TDC I just did it like the way I saw it on the video bt this guy said I should've done that n I told him I that this is how u did it I said cause I'm doing it like u did it on the video
@@linshebola8080 I haven't heard of needing to re-thread the engine block for the cylinder head bolts, but yeah you can take a microfiber cloth and wipe clean the cylinders. You would just rotate the crank pulley to move the pistons. As for the TDC position, I did do that in the video and advised to also do that because it makes things easier with this engine. Doesn't mean that it needs to have been done, because with this specific engine you'll be aligning the timing gears with the special links on the timing chain when re-assembling the engine. But putting it into TDC makes it easier to do that . Other engines you have to put them into TDC or else you'll damage them when trying to start it.
Can ignition coil cause any damage to head gasket? I changed spark plug and ignition coil ever since then problems seem to find their way to my car.
If there's issues with the coils that will lead to misfiring and timing issues, which can cause more than just head gasket issues
@@HectorTTalks can u pls suggest me affordable and good ignition coils?
@@TheJoeJoe1111 Of course!! While OEM brands can be expensive, but I did find this pack on Amazon with good reviews and a 5% off coupon amzn.to/3pXupkg !
Do these engines need special tools for locking the cams and crankshaft?
I haven't work on the crank yet, but for the cams I know there should be a special tool but I just used an open ended 24mm wrench
I have 2006 Altima 2.5 that started running rough. Checked coils and plugs and all within specs. Changed radiator today along with new coolant hoses. Used coolant vacuum lift however could not hold vacuum. Performed pressure test and could not hold pressure. Checked the oil dipstick and now overfilled with coolant. Would this be a bad head gasket? Thanks for the great videos.!!
That sounds like it's blown through the gasket, especially if it's watery or has milky looking oil from the valve covers.
I would like to see how u actually took off the tensioner n the spring on the gears when u we're doing the head gasket video cause it doesn't show how u took it off
I didn't have a tripod and couldn't do it while holding the camera but basically I used a telescoping magnet and held it onto the little spring and piston so they wouldn't fall into the timing cover
I hope I can get a quick answer if possible lol. What do I do if I accidentally dropped the push rod of the chain tensioner down into the void of the bottom part of the timing chais??
@@krisboesche2454 yeah so what do I do can u let me know please
My tensioner spring fell down there too. Does anyone have the answer if it goes down to the oil pan or did everyone have to pull timing cover. This answer will save viewers a bunch of time.
Voice does not match the face lol
Nice video I need to do the same
Thanks! It's definitely work to complete it, but doing it yourself can save a ton!
you dont machine a head for a mls gasket it because its warped
brandi eller hey please specify your wordage.
um it blew cause of lack of maintenance more than likely, i have the same engine with over 300000 miles never needed no head gasket
That probably was the cause because i bought the car and it was leaking oil everywhere and already had the blown gasket. The person i bought it from let it go for $300 and actually couldn't remember the last time they had an oil change. Now luckily, the cylinder head wasn't warped, they checked it at the shop, which is why i had it machined, just to make sure it had a smooth mating surface.
Mine went at 70k with regular maintenance. It's a common issue for them to fail early
@@445fear6 yeah they're good when they want to be but unfortunately there's numerous things that go on these engines no matter what
Did you need to pull the power steering pump too? The book says you do, but I didn't see that in your video.
I didn't remove it, just because it wasn't in my way. Don't really remember it being connected to the cylinder head.
Great video and very informative thanks!
So do I have to take off the tensioner for the timing chain when I'm doing the head gasket n what kind of pin should I use when I do the tensioner
Yes, you'll need to remove it to take the timing chain off the cam gears. And I just used an extended push pin that was long enough to hold the spring and piston into the tensioner until reinstalling it. It might be helpful for you to push in the piston first then put in the pin before taking off the tensioner to make it a bit easier
@@HectorTTalks ok, so I take the two bolts on there off r do I do the pin first
@@linshebola8080 pin first so the spring doesn't shoot out.
@@linshebola8080 pin first
how many actual hours did you spend replacing the head gasket???
Worked on it for a few hours, for 2 days
@@HectorTTalks that's cool bro, keep up the great work
DUDE, QUIT STALLING AND GIT ON IT !
Go fly a kite with ur hatin ass. All u gotta do is fast forward its one press and u where u wanna be. So shut the hell up hating ass
what's the price to get that changed
It varies from shop to shop, but could be easily up to $1000+
What state are you in can I bring my car to you.
@@jovantetaylor7069 I live in Florida but we're in lockdown right now due to the quarantine. But after its all blown over you can come and i can help you if its bot that much out of the way for you!
Lol I live in Florida as well but I ended up junking it due to no compression. I wish I would have known before spending 700 on spark plugs valve cover ignition coil etc. I would have just dropped a new/old engine
@@jovantetaylor7069 Dang I know the feeling. That happened to me with a Mazda years ago before i had any of my diagnostic tools.
Thanks by the way I've removed everything will remove alternator fuse box then ill crank the engine to tdc and start dissasembley of sprocket cam bolts but before that want to know how to dissasemble the intake mainfold it's a night mare of the whole job 😵😵😵
Space so tight you can't see well 🤪🤪🤪
OMG
Yeah the intake is a pain. Theres a few hidden bolts on the manifold but what i did was loosen the bolts and brackets enough to move it off the cylinder head but not actually out of the engine bay
@@HectorTTalks ill try but this is the most difficult part cause of no space to work and lack of view but hope I can do something and remove it like you
But what's the tourque specification for those screws 🤔
Or just snug it 😁
For that i honestly used my phone and put on the camera to look around for the bolts and clips
@@HectorTTalks thanks just recently bought handheld boroscope ill use it it'll be easier thanks alot maaan 👍👍👍
Yeah that'll be easier than using a phone lol
U had to remove the cams to remove the head?
Yes because the head bolts are directly under the cam lobes
@@HectorTTalks thnx....nice vid

Im so sorry! I didn't have my tripod stand which is why it's not stationery but i am looking into getting a new one so future videos will have less movement unless i need to point something out up close.

@@amberstar203 you're welcome! My channel is small enough that i can respond to everyone lol, especially with these videos because people always have more questions that i don't address in the videos
Appreciate the videos but as a friendly suggestion, don’t explain the entire process if you’re just going to do it. Explain as you go. Too many people will pass your video after 30 seconds of inaction. Helps a lot to jump right into it.
That is good advice and I definitely agree, especially now looking back on it. I've gotten a little better and thats one of the reasons I want to redo this video lol
Do u have to put engine on top dead center to replace head gasket or can u just mark as valve cover removed an timing chain cover removed in position car was turned off
@@nylajohn2132 I found out later on that you don't have to put it into TDC, just be sure to mark the valves and timing chain/gears
