U can unbolt intake off just look it up no need for extra stuff to come off..
Thanks man ur the only one out there that starts the video from the beginning of the process.
One of the better videos I've seen on this engine. Please keep up the good work!
Thank you so much!
Thanks for the video. I’m in the process removing the cylinder head also to perform piston re-ring. #2 has excessive blow by and low compression. Ordered a re-ring kit, should keep me busy for a while. It’s a low budget build up and probably be flipping the Accord or keep her 🤔 She’s been a great ride commuting to work 132 miles RT Mon-Fri...Cheaper to keep her 👍
Great Video, seeing you go through all that trouble, makes it clear how hard the head is to be removed with the intake intack, would not want to have to do that reinstall, sence the timing belt and water pump will come into play, I'd probably just pull the engine and do all the work the engine will probably need on a engine stand
Don't try pulling the head off in one fell swoop. There's studs on the intake side too. Remove the intake manifold bracket bolt from underneath so you can slide the intake manifold back and clear the studs. If you can find some M8-1.25 x 30mm JIS (12mm head) 10.9 flange bolts, you can use those instead as long as you use them with two star washers and one regular washer as shown below:
[M8-1.25 x 30mm JIS bolt] --> [star washer] --> [regular washer] --> [star washer] --> [intake or exhaust manifold]
21 Ft-Lbs. on the intake and exhaust side. Don't over-torque, and don't do this without all three washers or the bolts will bottom out in the head before clamping anything. A little loc-tite on the threads probably wouldn't hurt either.
Great video overall. You saved me alot of time in some areas so i appreciate it. Did the removal yesterday....my back is killing me lol. (I ended up removing the Cam Sprocket bolt and rigged it to a stick to keep it up in almost the same position (with wire)...so i didnt have to do all the other stuff with the timing belt..pain to remove the head with the manifold attached but its the only way reasonable....cant imagine how much fun its going to be to install 😣🤣
Very nice man, thank you for sharing your knowledge.
Great video.
I am in the process of removing the lower intake to replace the lower intake gasket.
My idle control valve was messed up. As I removed the upper intake ( not to bad) and checked my idle valve. It was plugged with leaves! Reason, I was running my Honda without an air filter🙈
So when I bought the gasket , it only came as a kit. So now I'm trying to remove the lower intake and it looks tough!
Looks like I have to lift the car to get to the lower intake bolts on the bottom.
So I was hoping this video would show how to do it. But Great video 👍
At work, for me, i use my 1/2 impact to brake them loose and use my 3/8 air ratchet to take them out
Everything to the middle of the video looks like pretty good info. But that wiring connector under the v-tec solenoid is not the "coolant temp sensor" it is "VVT (variable valve timing) oil pressure sensor" just thought of give you heads up in case you need to replace it as it does nothing for coolant temp but a lot for valve timing if your v- tec is screwing up.
Next time remove the exhaust manifold completely, and remove bolts that hold intake manifold, so that intake can be left in place except for those bolts that support the intake to the block. Yes these bolts are hard to get to. Also this would be a good time to change those o-rings under the rocker arm assembly. Then too, you will probably half to take tension off of timing belt before you can install it again. Might even be time to replace the belt or belt's now that it's apart. Getting the harmonic balancer bolt out, is a chore too. Good luck!
There aren't any "bolts" holding the intake or exhaust to that head. They're double-ended studs with marsden lock nuts...
@@gfyabc True, I should have said nuts instead of bolts, but you get the message,,,,,,
Haha! next time you’re going to be captain you’re doing it wrong you might want to be sure you’re say the right thing. hahaha jack hole.
Thumbs up for your efforts and your video..hopefully there’s part 2 from you.
there aint gonna be no part 2 😂 that cars sitting in a junk yard somewhere used for parts cuz the way the idiot ripped that head off there smh
Awsome video, thanks very much! Im getting ready to do mine and you're exactly right it's intemidating! But you showed several things i didnt expect so i really appreciate it!
Thank you! Best of luck with yours!
@@ModologyMotorsports just starting out year 1, this will help a lot for my class, thank you sir
Great video blake helped tremendously
great vid , Blake. Can now delete those other vid describing the process after its out which are worthless seeing the problems you encountered that would not have been evident in the other non-step by step vids. Thanks, my back is hurting seeing you hunched over that thing.
Thanks! That finally step off pulling the head off was painful! But also satisfying! I hope the video helped!
@@ModologyMotorsports i was wondering if you have to drain the radiator of coolant before removing the hose
You have done well
Awesome video thanks!
Great Video Thanks...
Hay, I pulled my cylinder head off and found a gap/burn in the gasket between the cylinders. When I looked down the cylinders and saw no cross hatching, do I need to hone them? Can I hone without taking out the pistons? I wasn't burning oil. Thanks
I tried doing this and realized that I was missing one of these bolts and come to find out it has broke off so do you know how to remove the broken bolt to replace this cylinder head
Awesome vid thanks!
Dude what is the playlist for this!? Lol its awesome. Seriously
And thanks for the great vid, lots of help.
Thanks! The music came from a channel called "Royalty Free Music For Content Creators."
Awesome! Thanks!
Chill beats!
Thank you. I'm about to do mine. I accidently loosened the radiator cap, lost water and the car really messed up.im a mechanic, but I always watch other's methods.
Did you loosen the timing belt at the tensioner
Do you know what the hose in the middle of the valve head is?
Are the heads on the F23A4 and F23A1 the same/interchangeable?
I pulled head + intake . Rebuilding entire engine rn.
What's the model of your Milwaukee rachet?
The head bolts are a regular 12point socket if they were inverted like an Allen head but with 12 points that called a serrated socket
I really goofed when I got to the head bolts lol. Not my proudest moment. 😉
@@ModologyMotorsports is all good it happens to me more and more the older I get thanks for the video foreal now I have to go in and tackle my 96 I just bought for cheep but someone already took the head off and they didn't have a clue the pulled wires out of 2 plugs I'm going to have fun all the parts in the trunk trying to get a good visual on it again thanks for the tips
I have to do this same job! great video. Where did you get your Milwaukee nut driver?
Amazon! Good luck!
One of the best how to videos good job man.
What’s the name of the power tool u use?
What about marking the distributor for TDC on number one piston??
It only goes in 2 ways , right or 180 degrees out
What was your total hours for the job?
Nice job just wingin' it. That's how I roll... Lol, at 16:55, did you go the wrong way at first when attacking those 12 point head bolts? At least it didn't snap off, that could have been nasty.
Sometimes when the bolts Are verte tight, ir helps them hey loose going the opposite way just a little before going the tight way
Do have 2. Take to Shop when u take it Of r Can u change it and put bact togther put new oil n speak pulgs ?
If the engine overheats and your head gasket fails, it's best to take it to a machine shop to be resurfaced. If you just change the head gasket, odds are your just buying yourself time before it fails again.
Is this basically how I remove the cover of the cylinder to change my head gasket right ?
Yes. Once you pull the cylinder head off, your head gasket is right there sitting on top of the block. Take old one off, then install new and reassemble basically. *Dont forget to add coolant to the radiator once everything is reassembled*
How would you put the timing belt back on with it being tight and taken off with a flat head and hammer? When the new head gets put on what about timing it?
You could always just set the time on the block and the head separately. Putting the no. 1 cylinder at TDC, and making sure the valves are both closed.
Awesome! Good luck! Don't forget the hoses under the intake manifold!
@@ModologyMotorsports bro wheres the car now JUNK YARD 😂 u hacked the fuk out the head getting it out man y not just spend the extra 10 min UNBOLTING THEintke u should be embarrassed u even posted this video 😂
Quick question do I have to replace the head bolts does it really matter that’s my only concern the gasket set don’t come with the bolts
If it's overheated I would. The bolts can stretch when the head warps.
Thanks.. yeah it was overheating problems
My question anybody way not leave intake and everything in car unbolt intake from head leave intake in the car just wondering getting ready to do 1
That sentence.
@@mrreviewsitall7496 Yeah...yikes
Yeah they used 12 point head bolts which need a 12 head socket
You could've use a regular 14mm btw I did worked fine
I'm having trouble getting mine to get on. What brand was your socket?
Dude, which head bolt was the long one? Or were there more than one long one?
Center rear. the center front is unique as well, but not as long.
@@luistigerfox Cool. Thanx!
You didn’t have to remove the alternator bolt. I didn’t anyway.
How long did it take you to do this?
Took me 2 days. Because of filming, but it could be done in 4 to 6 hours
Cmon bro, you don't know what a 12 point socket is? And you dismantled 3X more than you needed to on that engine. How long did you tighten the head bolts trying to get them off? Lefty loosie man!! Glad I watched this "what not to do" video lmao.
I thought I was seeing things lol
@21:13 when you have a cheater bar in hand but decide to just fist pound the rachet to get the bolt loose hahahaha I lost it . Great video BTW thanks, but you didn't show the part when you went under the car to show us what you removed.
I thought I was gonna have to remove the bracket that goes from the bottom of the intake to the block. But the bracket was already missing. 🤷♂️
Manual impact wrench... 'git-r-done'😎
15:15 Those are 12-point head bolts. Use a 12-point socket. And using a 9/16" instead of the 14mm was pretty careless if you ask me. 9/16" is slightly larger than 14mm, and they put 12-point bolts in there for a reason... Good luck not rounding those bolt heads.
I got them out. I wasn't planning on reusing the same head bolts. I also ordered the proper socket after the video for reassembly. But this is good information! Thanks for the heads up!
What was the reason for removing the head
Blown head gasket
Did the timing belt go back on easily or too much tension?
The key is the timing belt tensioner. It went back on fairly easy.
@@ModologyMotorsports did you have to take the crankshaft pully off to get to the timing tentioner?
No, but the crankshaft pully does have to come off.
The torque spec for those are 22ft lbs 90 + 90 and 90 more degrees if new bolts are used.. And thats onku for the F23A1 to F23A5 engines
Just bought my 95 accord head bolts are super stuck. I cracked a 14mm socket twice!
If you haven't already, try tightening them a little before loosening. They sound they make when they break loose can be a little worrisome lol.
@@ModologyMotorsports thank you for your help, i was able to break them free by putting some PB Blaster on them (whatever that really did), and hit the bolt on the head with a center punch and a 2lbs hammer two wacks! ... and turn...two more wacks and we are free!
Nice! Glad I could help!
Make sure to use a 12 point socket or you will strip the head bolts. Thats no fun removing them
Hi, I would like to ask why is there a hole at the bottom right of the top cover. I thought my mechanic forgot to put the screw back but yours its the same as well. What is the function of that whole? Thanks in advance.
to put ur pp in it
Mine is like that too. I assume its chain mounts in case you want to take the engine out
How many head bolts are there ?
I have six if I remember correctly on my f22b2. To get valve cover off (at least on my engine) I only had to disconnect breather valve and the other hose on valve cover... and obviously the bolts lol
Wait sorry I have RUclips auto play on and I thought he was just removing valve cover and it caught my eye when he started removing other stuff. Didn’t realize he was pulling the head. I cannot help you with that (with any precise details at least)
It’s like 8 or 10 I can’t remember. But they are 14mm 12 point head bolts.
How long did it take to remove it
About 4 hours, but I had to keep stopping to move the camera.
book gives you 6.2 hours to remove and install
What's the Milwaukie drill model u are using in the video? Thx
Who did the intro?
We made it on a website called Render Forrest
How did u know the head gasket was blown?
It was leaking coolant into the oil.
@@ModologyMotorsports thanks for the help!!
Couldn't help but notice, you have coolant in your Pistons
Yeah it leaked from the head when I pulled it off.
@@ModologyMotorsports Couldn't help but notice, part of your engine is missing.
No one is showing on youtube how to do this on a acura mdx. I have done everything, except I am stuck at removing the exhaust manifold bolts. I do not know how to get these dang bolts off to free this, so that I can remove my cylinder head. I am incredibly frustrated. I can't hire a mechanic because no mechanic wants to start work where I left off. So I am on my own :(
@MizzChocs did you try bolt extractor?
any updates??
Aye I know what the problem is
😀
I notice you took the timing belt off the dangerous way
Why wouldn't you be using 12 point sockets anyway? They have far better bite, even on the 6 point nuts and bolts.
That's all that came in my harbor freight tool kit lol. It was a big enough set to get me started, and I can upgrade from there. 👍
@@ModologyMotorsports Ha! Same here man. Still usimg my 6 year old Harbor Freight 2 ton jack and jack stands
what’s the tool you used at 17:00
That was a part of an old lamp I used as a cheater bar. The head bolts are strong steel and can be exhausting to break loose with just a ratchet. 👍
@@ModologyMotorsports Hmm, can a female do this job? I have a '93 Honda Accord that I'm pretty sure has a blown head gasket based on symptoms. I recently took the cylinder head off to replace spark plug tube seals (both ends) which fixed oil leaking into plug chambers, new spark plugs, and new valve cover gasket. That was my first ever anything on a car, aside from putting fluids in. So, I feel good that I was able to do that. But, this blown head gasket is a bit intimidating, considering all the bolts, hoses, and sounds like hard to break loose.
About how many things did you end up disconnecting? Is it difficult to put it all back together?
Great video, by the way. Very helpful for a novice to understand what's involved.
@@ModologyMotorsports Also, if I were to tackle this, how heavy is the piece I'll be removing to get to the gasket? I'm roughly 120 lbs. Decently strong for my small size, but, I need to know if it's even doable for someone my size/strength!
If you can get the intake manifold off, it's not too terribly heavy. I'm just tall and was having to lean over to pick it up. Also in the video I wasn't very gentle. Mostly because it was going straight to the machine shop.
That's why Honda doesn't like replacing heads. They try to scare you into buying a new engine for a ridiculous price. They are lazy bastards.
I mean... you need to do a lot of the same work when you replace an engine, but with a new engine the customer gets a new engine. You have less liability running a previously damaged engine. Can't always be sure what happened while the head gasket was blown. Whatever damaged the gasket may have warped things. It's a whole bucket of potential problems. Or, nice new engine, almost guaranteed no issues for the customer and dealer.
The music is twice as loud as your voice
If anyone watches this video, be sure to leave the intake in the car and just remove the head by itself. Also I would like to see how you get the timing belt back on without removing the timing chain cover and the harmonic balancer,,,,,,,,,,,,,,,
What’s the background music playing at 5 min mark ?
That is a lower back killer
It sure is!
Damn sure is! I'm 6' and you being 6.5' I feel for ya
FOR THE HORDE !!!!! LOL
😂😂😂😂😂😂😂
What year is this car from? I have an f18b2 from 99
It's an 02 👍
@@ModologyMotorsports ah k same generation as mine yay
The neglect on that engine thooooo omg:(
Yeah. Wasn't running when I bought it. Had been sitting for a while.
I mean... it's an old ass car, with an engine that's nothing special... of course it has been neglected and it's not really a big shame. It's a fairly standard use and abuse daily grocery getter.

Its all related
Im not mad, im just soapboxing it lol
Peace dogg ✌🏼
Mines is a twelve point 14 mm my guy for them head bolts
Not sure of this guy is a mechanic or just doing a DIY, he removed the Cylinder head without undocking the intake
What was the instrumental at 17:00
You shouldn’t took the intake off that’s extra work boss.
decent video! but a couple of tings , first NO cuss words? hmmm! sechond your neighbor know you did this to his car when it didn't need it? and found the head on da lawn? an looked round an sawn noboty? an you inside dwinking a bera? an cold un at dat? 😀😀wood hav been nice to hav dancin girlie wit da musik! 😀

Awesome video but please please please stop with the effin' muzak
You couldve just removed the head and leace the intakemanifold exactly where it is
From my experience the intake manifold is a bitch to remove while the heads in the car
@@mrorganic13 I just did and finished this job a little over a week ago, it is much simpler to remove the head with the intake in the car but this is assuming you won't be changing the rest of the gaskets on the intake manifold
@@majorkin19 I’ll update you tomorrow when I pull head off, but from my experience the bolts are partitioned in a way you might as well pull head off with them attached
@@majorkin19was pretty simple sorry for the lateness, only thing that got me was I forgot a wiring harness bracket underneath the intake when removing the bracket bolt so it annoyed the crap out of me when removing , if I would of removed that one bracket while down there it was def easier with the intake on then off just due to not having to finagle for those manifold bolts
Damn what happend to that car.
😂🤣🤣🤣🤣😂😂🤣🤣🤣🤣😂🤣😂
look like it set for a while... and he didnt blow the nuts off... ha
@@StevenSmith6942_ 🤣🤣🤣🤣🤣
It had been sitting for a while with a blown head gasket when I bought it. Got it really cheap. In the end, it was running, cleaned up, and sold.
@@ModologyMotorsports thats nice bro. I wanna buy a car like that too for real cheao and then fix it up. Glad you got it back up n running. Good thing you had it in your yard. Gives you plenty of time to work on it.
If you guys are gonna do this Please DISCONNECT THE BATTERY FIRST thanks guys
Erick Cid ok mom
What a TOOL safety guy ERICK
Josh scott okay josh I was being a smart ass first of all I’m a professional mechanic that does this shit for a living so yes I’m strict
That's a lot of work! How about try a blue devil head gasket sealant 1st?
I tried that stuff on a very small head gasket leak and it didn't work and it destroyed my water pump!
should of worn gloves.. i can see rat droppings everywhere, if you see snail shells you might have a rat problem.
The car had been sitting for a while before I bought it. The previous owner didn't want to fix it. It's getting a deep cleaning before I start to drive it. All the wiring seems to be ok thankfully. 👍
Nice! Good work sir!
I guess it's safe to say that they use Salt on the roads where you're from....😳😳
Wow now yunk yard the car not running anymore 😂
😂😂😂😂🤣🤣🤣😂😂🤣😂😂 OGGG
I was gonna play this at 1.5x speed but then the music came on.
@15:14 And I'm done. It's a 12 point dude. You have a motorsports channel.
🤣🤣🤣 Yeah, lol, i didn't have a 12 point in the tool set I've got. I didn't know what I was looking at.
Really? The whole video sucks because of a brain fart?
Hey jack black wannabe I can’t seem to find any videos you have done to help people out.
My question is...?! Why you need to remove the fuel line, I mean it's up it of the way in the video...... I don't understand
