Part eleven of a video series rebuilding a F23A1 Honda Accord engine.
In the interest of complete accuracy, this is a re-upload of the original video to address some errors that I made. Thanks to the previous viewers that pointed them out to me. I hate being wrong, but I want it right!
Corrections begin at • F23 Honda Accord Engin...
We are going to get the cam, rocker assembly and timing belts installed and show the procedure for getting the timing set.
There are many ways to "skin the cat" and these are the methods that I use. Any criticisms or alternate methods posted in the comments are welcome, just keep it civil.

I feel like I've performed this procedure 50 times in the past yet I'm always timid again and again, but after watching your video I feel confidently refreshed and I simply couldn't thank you enough for your efforts!!!
Thank you! I'm glad to hear you found the video to be helpful.
I can not thank you enough for these very well detailed and great camera placement videos. Not being able to afford the money to pay mechanic for head gasket job, these videos have helped me and my family tremendously! May God Bless you and your family!!! Thanks again!!!
4 years later and this video is still helping people. It definitely helped me. Thank you brother🤙
No problem 👍
Fantastic video! Fantastic series! I'm changing a timing belt and gaskets for the first time. Your video made it possible for me to afford to fix my car. Many thanks. 1990 Honda Accord. No one goes into depth like you.
Thank you! It it always great to hear the effort I put into these videos were helpful and appreciated.
Spent almost an hour looking for specific timing instructions for one of these engines in my shop. You're a lifesaver. Thank you.
Thanks for taking a moment to comment! Glad the video was helpful.
@@ktecgarage There aren't enough good resources with positive feedback for actual techs out there, so videos like these, at least I believe, should be praised. Also got me thinking about putting an F23 in my EF hatch now. 😂
You made something that could seem very intimidating look super easy. This video helped me beyond measure! Thanks so much!
Thank you! I'm always happy to know my videos helped someone out.
Your tips are beyond valuable in problem prevention, THANK YOU!!!
Thanks again @ktec. I finished by build last week, basically same engine (mine is AT though), same AMZN rebuild kit. I used your step by step often.
On the rocker arm assembly, I clamped them so they didn't move, but be very careful to inspect the assembly before you put it down and torque down. There are 4 timing plates that are held by springs in the assembly. If you flip the assembly over, you'll see notches that the plates are supposed to stay on top of. I installed my rocker assembly and 2 were below. This basically meant that one valve each on those two were always pushed down. When I went to do a valve lash adjustment those valves also would adjust since there was zero gap between. I was rushing to see if it would start because was so close and sun was going down. Anyway, the plate piece broke off after the engine was running for about 5-10 minutes. I was lucky, dropped the pan and found it in one piece.
@ktec please do a rocker arm disassembly and reassembly :) I haven't seen anyone with the F23 done, only a bunch of civics.
Hope you get plenty of use out of your rebuild! Glad to hear you got that rocker arm assembly straightened out. The comment thread got deleted, but I did post you a diagram of that part of yours that broke off. I suspected that was the issue. If I had known about that part when I did my rebuild, I would have included the info.
Please please please please
According to the Service Manual, you are to leave the cam bolts in place to keep it from popping apart when removing the rocker assembly. I noticed that in the manual after I pulled all the bolts and mine popped apart. But, your video is by the far the one of the best i've seen.
Thank you for adding that info.
Great video and explanation of this process! I've been stumped and over thinking this (especially oil pump timing setup) and you just helped me out so much my man!! God bless!! 🙏🏼🙌🏼

Thank you! Glad to hear it helped you out.
😂@@ktecgarage
Awesome video!!! I am now confident I will be able to do the work on my 2002 Honda Accord correctly based on your instructions. Thank you so much for explaining it thoroughly.
Good luck with your repairs!
So glad I found this. This series is invaluable to me. Too many helpful hints to list. Thanks.👍
So glad you found the videos. They were a lot of work, but helping folks made it worth it. Thanks!
Thanks my friend. It’s my first time doing this maintenance and it’s been crazy easy because of your videos. I really appreciate it.
And thank you for commenting. I'm very glad to hear these videos were helpful.
Great video 👍 I am going to be doing a timing belt replacement on my folks 98 Odyssey with the F23 engine for safe measures. They bought it used with only 53,000 thousand miles on the clock and never has had a timing belt replaced over 23 years...Belonged to an older lady and the van has been parked over 5 years in her garage. New battery, new tires, oil change, drive belts, and the dreadful California smog inspection, the car passed with flying colors. People had already offered to buy the Odyssey from my folks 😂
Yep. You have to love the Hondas. Just basic maintenance keeps them running forever. Thanks for sharing!
This are one of the completed video of zincrronicing on 2.3 honda 1998 to 02 ,I'm ever seem. Thanks for the info. This video help to fix my 1998 vtech honda , well some mech hanging on the timing zincronised was a fault by the ones work on before , but now is OK thank to you ' k- Tech .
Very detailed video, found it very informative and precise. Now I'm more equipped to take on my 95 odyssey tomorrow which has a similar engine. Thank you Ktec Garage!
Thank you stopping by and commenting. Hope your repair goes well!
You're the best! Thank you for a very detailed video!
I just got a f22 engine. Thank you for the videos. Super similar setup.
Thank for your comments. Glad to hear the videps might be able to help you.
alright time to buy an f23 engine and play with it using these instructions
There is a guy on UA-cam with a turbo F23 in a sleeper Accord. Fun stuff!
Good Video. You did a good job teaching the timing proecess and the cam shaft assembly.
Thank you! It's tedious.
Ktec Grate video, I enjoy you explaining in very well detail not like other videos. Grate job, Thank you.
And thank you for the compliment. Glad you enjoyed the video!
👍 love the video. It's gonna make my job so much easier.
Thank you! Good luck with your repair.
Excelent video!! Thank you so much!!
Thank you for taking a moment to comment!
Nice job
Thank you!
240k on my 2.3 just doing the belt today..
Thanks for the video, helps
Good luck with the repair. Glad to hear this was helpful.
Best damn vid o. This ive seen!!!💯💯💯
Much easier to show how it's done with the engine on a stand. I'm glad to know it was helpful to you. Thank you for taking a moment to comment!
Thank you. Very helpful information. Just liked and subscribed.
Glad to hear the content was helpful. Thank you!
Thank you brother .!! 😆
👍
Love this video
Thank you!
Very Great !
Thank you
Finally!!! Someone who does a full step by step video with out skipping a step and leaving people asking questions.. then the uploader gets mad that we ask those questions. Great video I am subscribing for sure! My car wont rev past 4500 rpms and I found out that it was off a couple teeth on timing I havent checked but that is the culprit. And watching this video makes me positive I can set the timing myself now. Thank you and keep uploading great information videos like these!!!
I'm very glad to hear this is going to help you out. Thanks for the comments!
@@ktecgarage hey I've run into a snag.. I cannot get the cam gear on without the keyway falling out.. I have my belt on the gear and I am trying to install it that way does the keyway go in first? Or do I slide it in somehow after the gear is on? Like tap it in with something? I was fighting the gear then it went to far til it was scraping the back of the plastic please help if you can
The cam gear key is built in on my setup. Do u mean the crank gear key? That goes on first, then the gear and then the belt.
@@ktecgarage when the cam gear is off the key way came off with it. It's the same as the crank gear pulley key way but just a bit smaller.. but I guess I'll try and put it on first. I'm just having a hard time getting the crank pulley bolt off I broke two extensions and my actual tire iron .. and it's still not off yet..
Use a MAP gas torch on that bolt for 3 minutes.
Think u 😢😮❤
You are very welcome!
thank you !!!
And thank you for commenting! Glad to hear the video was helpful.
Re-upload, see description. Thanks for the previous views and likes!
Don’t the notch need to Aline with the point on the oil housing
Lots of notches in that video! Which one? And if anyone is wondering, car runs and drives perfect using the methods to align everything I used in this video.
Ktec Garage the notch on the front balance shaft
Both notches don’t seem to line exactly up
If I remember correctly, the line on the pulley points at 9 o'clock and the notch on the top of the shaft points to 12 o'clock. I'm sorry if I'm not picking up on exactly what you are asking.
Hi bro I love your videos 😁
Thanks man!
Thanks sir
Glad to hear the video helped you out. Thanks for commenting!
10no 1 bolt missing in main timing adjust bearing Under tension spring. Thanks for this video
And thank you for watching and commenting.
Спасибо!
добро пожаловать!
Did you just say "vtec isn't something magical or mystical"
Thats some hoo-haw.
Vtec is magical 😅
I said magical or mystical. Vtec just kicked in, yo!
Thanks ktec... Awesome video on this F23A1!
I have a jdm F23A FROM JAPAN it's a awesome engine.. I have a knocking noise it's my loss motion springs. You do not have the original ones. If it's OK, can you please let me know if there'The b series or the h series you are using...THANKS!
excellent video thanks for sharing I have a question my honda accord 99 they detected a fault that stops working pinston 3 I thought it was an injector but it is not like that the mechanic says that only by uncovering you can know the car with air conditioning gets ugly weak but It does not turn off it turns on the check engine light maisfire what should I do, Hugs
If there is fuel and spark for piston 3, you need to do a compression and leak down test to make sure the valves and head gasket are sealing the cylinder. Eric The Car Guy just did a video showing how that is done. It's called mechanic's special. Thanks for watching and commenting!
❤
👍
Can you tell me if the gates timing belt kit for a f23a1 will fit on a F23Z5 hope you can help me thankyou 😁
If the length and tooth count is the same, then yes. I don't know for sure. Good luck!
whe renstalling would wanna reoil anything on the head im new and just decked my head and im putting it all back together and was suggested to use white lithum grease on camshaft like in video but anything else i need to grease like the camshaftholder or just anything else lol
You could pour a quart of oil over the assembly with the valve cover off. I spin the engine with the spark plugs out and the fuel injectors disconnected for about 30-45 seconds and let the oil pump prime. Good luck!
When I was doing the 4 rotations with the belt, I notice that when I am cranking the engine CCW that I can hear and feel the pistons drag within the cylinder walls. Is there supposed to be resistance for half of the rotation and then get smooth for the remainder? The audible sound of the pistons makes me nervous. Is this normal.
Also do you have a Instagram or any other social media that you can get DMs through?
If the spark plugs are installed, cylinder compression will cause it to feel uneven when your rotating the crank. If the engine has not been ran in a while, there won't be oil on the cylinder walls and you will hear the rings dragging. It's not going to hurt anything.
I do have an Instagram account, but I do not regularly monitor it.
Paul Nassau Bahamas I got it thanks
Excuse me I have a question . I just make the change of the timing belts on 1998 Honda Accord 2.3l . And after reinstall the belts, the engine it’s when the RPMS to high. What you think I did wrong ? Thanks for your help.
If the belt is wrong by even one gear tooth the engine will not run right. Double check the timing marks with the crank at top dead center. Also check for vacuum leaks.
Besides that main seal on the camshaft. Is there another seal at the opposite end?
The distributor has an O ring around its shaft that seals the other side. Hope that helps.
I can’t tell if that V-shaped notch on the rear valance chef/oil pump sprocket is supposed to be lined up 12 o’clock or that that that is stamped on the outside of the sprocket please help
I really want to help you, but I don't quiet understand your question. The sproket on the crank gear has a triangle that should point to the mark on the oil pump at 12 o'clock. The front balance shaft has a line that should be at 9 o'clock, and the rear balance shaft should be locked in place with a screwdriver or long bolt through the port by the the VIN plate on the rear of the engine.
You have so many videos! I have the 01 Accord EX Sedan with also a 5 speed manual, does that mean I have the F23 engine?
If it is the four cylinder engine then it is the F23. The engine rebuild series would pertain to your car as well.
Thanks for the video, I have a question , I followed everything step by step but when I assemble my rocker arms back on and torque them down, my cam is literally stuck it takes a lot to turn it and when it finally goes it jumps and spins 90 degrees before it stops and has the same problem. No belts are connected. Block is at TDC. Any idea what I’m doing wrong?
Silly question, but are the spark plugs installed?
Could be something with the rockers not sitting on the valves right or one of the VTEC components has slipped out of position.
I'd take the whole assembly off, check everything and try again.
@@ktecgarage spark plugs are not in, It seems like it way to tight even when I’m not finished torquing it. I think it’s the spring on the vtec love that has all the pressure on it. It’s all longed up right though. My cam should spin freely with out much effort right? Do you think it’s because my block is at TDC and it could be hitting my piston?
If you are trying to spin the cam without moving the crank, the valves will hit the pistons. If you muscled it past, you may have bent some valves. That's why you need to put the rocker assembly on with the cam gear in the up position.
You should never move the crank or cam without the timing belt installed. If you turned it past the point that it was binding, you should really pull the head back off and check the pistons for damage and take the valves out and see if you bent them.
Sorry to give you bad news.
What should be done if the hydraulic piston or pin that activates the vtec gets stuck and does not return? Is it necessary to disassemble the rocker arms to be able to repair it or can it be solved without disassembling? To disassemble the rocker arms, all the springs of the rest of the valves must be decompressed? i am having this problem on a f23a accord engine on cylinder #4. the vtec pin spring is stuck, Greetings from Venezuela
Could be a couple of things. The spring behind that plug could be broke. Or it has worn down enough that it doesn't fit right. I'm afraid you will have to disassemble it or find another in a junkyard. Good luck!
Hermano un saludo cordial desde aka de Venezuela queria saber si si una camara de honda Accord 2000 aplica para un honda Accord f23 motor 2.3
This is the F23 in the video. All Of the Accords from 1998-2002 had the same 4 cylinder engine.
Este es el F23 en el video. Todos los Accord de 1998 a 2002 tenían el mismo motor de 4 cilindros.
¿Son comunes los Accords en Venezuela?
Question about brake purging. What can I do if the purging screw is completely stuck in rust ?
I'd spray it with WD40, let it sit for a while and then twist it off with vice grips. They sell them at parts stores. They are called bleeder valves.
@@ktecgarage ok thank you
Is it necessary to put a bolt in the back tensioner arm thing?
No bolt , spring only
ive seen a lot of videos on this engine and everyone does the timing different. So what your saying is put the first tensioner on and give it just enough pressure up, to make sure that everything is timed up after 4 rotations cc, and then when you move to the balancer belt, you hand tighten the 2nd bigger bolt, which allows the two tensioners to be pulled by the springs, and then when you turn cc 4 more times, that allows the tension to move for both to be just perfect? you then just tighten the 2 2nd tension bolts and you are gtg? when you started the engine after this did it have any issues? the timing belt seemed a little loose to me from watching other videos. they say 45 degrees is all you need and it looks like your first was 90 and the second was 45
The timing and tension is fine as demonstrated. I have a better video demonstrating the same engine here
ua-cam.com/video/acO-CGqFkwY/v-deo.html
I'm a bit better at videoing and talking now. It's tedious enough without explaining at the same time so sorry if it was a bit muddled. Hope you get it right!
@@ktecgarage everything was good, the tensioner part is where i got mixed up, checking it now
I see that the oil pump mark moved to 11 o' clock when you tightened the balance shaft belt. Is the timing still correct?
You rotate the crank slightly to tighten the belts. That moves the crank gear timing mark. If you did it right, all the belt teeth in their right spot, then everything moves in time. Rotate the crank counter clockwise two times back to the oil pump mark and everything lines back up if you did it right.
Thank you for watching and commenting!
good video good splanation but i thing belt is too loose!!!
I hear ya. The teeth on the timing belt takes care of that. It's not like a serpentine belt that needs more tension. Driven that car thousands of miles since that video and it hasn't jumped time. Trust me!
Thanks for commenting.
Is it all good if my timing belt covers are not put back on?
Well.... You are running the risk of something like a rock getting between the belt and a gear. That could wreck the whole engine. Not very likely to happen, but Honda puts them on for a reason.
What's the name of that clamp u used on the rocker arm
Irwin Quickgrip clamp
In the minute 32:40 the adjustment of the band is seen to be loose, that the band is loose is also bad?
If by the band you mean the timing belt, then no, it's not loose. Several people have asked about the tightness of the belt. If you can turn it 90 degrees and no more, then the tension is right. The belt has teeth and is not like an alternator or serpentine belt. If you over tighten, it can ruin the bearings on the water pump and tensioners. I've put a lot of miles on this car without issue. Trust me!
Thanks for the comment.
@@ktecgarage A few days ago I changed the time band (accord 91 ex 2.2) I tried not to adjust the timing belt too much, I read your answer and I checked how many degrees I could turn the belt and I think it is like 50 0 60 degrees, I will try to loosen it a little more, thanks for answering my question
отличный комент
Thank you!
Is it the same for f20b7 engine? looks the same to me, that's wy i'm asking
Probably? I dont have a solid answer for you. I've only worked on the F23.
I was following along with your videos as i did a head gasket job on my F23. Unfortunately I reached the "rocker arms and vtech parts flying everywhere" step literally one video pause before you said it.
😬 You can find exploded diagrams online that show the assembly. Pay very careful attention to the flat tabs that fit between the cylinders and their springs. Good luck.
@@ktecgarage You are the man. My engine has 292K on it. It definitely needs the full rebuild treatment, possibly machine work -- but for now, my first completely solo head gasket job is proving quite successful. Car runs again. Few other tidbits to sort out, but it's a daily driver again. Your videos were instrumental in that. Thank you.
Thanks for the kudos! I hope you get another 300k out of it.
How do you know that the cam shaft is on rotation 1 and not on rotation 2
Both the crank and cam rotate through 360 degrees. The pulley sizes take care of the rest. When you start with both at top dead center, or 0 degrees, you are good to go.
Can you help me with my HONDA ACCROD 98 the motor works normally but it can't take gas, ( I can't accelerated...
I would like to help but because of our different languages I would need to see a video of the problem.
Is there no torque spec for cam gear bolt?
27 ft lbs. I've never had an issue just rattling it on with a 3/8s impact.
I'm dealing with some frustrations and maybe fall into the 1% of people that accidentally turned cam gear opposite direction and the crank too. How I do get both back to TDC?
Oh. And if all that is too confusing, you can loosen all the cam journals under the valve cover. You don't have to take the cam out. Once the journals are loose and lifted up about a half an inch (13mm) you can put everything back in time and re-tourque the journals.
I just ran into this same issue. Tried rotating it and was met with lots of resistance and knew I should stop. I didn’t know the camshaft had to be in a certain position prior
Be sure to correct the torque on the 4 small bolts at both ends of the cam not 109 ft. lbs it will be inch. lbs
Yeah. I put up a comment on the screen for the correction. Maybe your device didn't show it right. Thanks for commenting!
Okay I tried to hold it together but my VTech rocker system is in a million pieces now and I'm kinda scared
I started to do a video last year showing how to assemble that but it was too tedious to film. There are exploded view diagrams you can google to help you get it back together. The hardest part to get right are the flat tabs that fit between the small chrome cylinders and their springs. Make sure the springs are holding the tabs in the correct position.
You can do it and good luck!
@@ktecgarage thanks for the tips will do
Приветствую! Совсем недавно купил хонду аккорд с двигателем F2,3 A от Одиссея. Извиняюсь, но скажите, знающие, при обрыве ремня ГРМ клапаны встретятся с поршнями? Ещё раз извиняюсь, но нигде толком не могу найти ответа! 😊
YES! If the belt breaks. The pistons can hit the valves and ruin the engine. The valve will bend or the piston could break. But not always. Good luck!
Yes.
So in other words, honda engines are susceptible to bullshit issues like every other engine. So this idea that Honda engines are the best thing since slaced bread is totally bullshit. Every engine ever designed has quirks and issues, no engine is perfect and if you have the knowledge, those issues don't mean much if you're willing and knowledgeable enough do the work yourself and not get robbed by someone else.
