- This one was a request from a couple of viewers, I like to keep you all happy so here you go. This video is actually taken from a larger video I call "Accord Smackdown", in it I replace the timing belt, radiator, a major service, and some other stuff that I don't remember. I think there will be a couple more videos from this "smackdown" in the future, there is some good stuff in there that I think you will like and possibly learn from. If you have other topics you would like covered don't hesitate to let me know, I'm happy to give you what you want. Post them as text or video responses to this or any of my videos.
I'm going to get the part number for the tool I used in the video sometime next week and post it here so keep your socks on and check back sometime next week.

Thanks again Eric for a very informative video. I just purchased a 91 Accord wagon with a very loud valve tick, and thanks to this video, it now runs as dead silent as my '90 Accord coupe. This was a great video for anyone needing to do this job. I got it right on the first try.
Yes, I had noo idea what I was doing when I started doing this either, it took years of practice before I became confident in what I was doing.
I respect that, thanks for that little bit of clarification. In my career as a technician I've encountered a few techs that I just didn't agree with, it's the reason I made Episode 1. The fact that you ask as many questions as you do says to me that you have an interest in doing the best you can do, in my book that makes for an excellent technician. Go with your gut and keep pursuing the best answer and remember no one person has them all.
Glad you got something from it, thanks for watching.
i love how Bill Burr shouted you out on the last joe rogan podcast
Which one?
Yes I have used it to diagnose a problem such as a sticking caliper but you have to be careful doing this and not drive on the road when you have a brake line clamped.
TWELVE YEARS LATER AND THE FIRST THING I SAY IS SHIT ERIC IS ONE OF THE BEST 😂
@AutoTechHector Yea, a good valve adjustment and a tight timing belt will cure just about anything on a Honda. Glad you got it solved, thanks for the update.
@90onenight Glad I could help, thanks for the comment.
Eric I love your videos it’s always refreshing to see the way other guys work and it’s obvious you are a very experienced Honda mechanic! I always pick up a couple pointers watching your videos, I like to think I could figure things out on my own but your hints and tricks they make me a better mechanic and I love these cars more every day. Keep it up!
Thank you Eric for the detailed straight forward video made in 2009.Just finished with water pump and timing belt replacement on my 1986 civic si. I followed the my honda shop manual and adjusted the valves accordingly. The car sounded like a diesel after the first and 2nd adjustments.Felt really frustrated then I saw your video and did it the master honda technician way and my very first car is now purring like a little kitten and happy again. Thank you so much brother for sharing your wealth of knowledge. Keep Wrenching.
Great job of explaining what could be very complicated. I'm 75 year old, woman, and a natural redhead. I only mention that b'cuz it explains how we differ from most women. We possess a dogged determination to succeed at something simply because we've ben told that we we won't be! Anyway, I have been working on my 1992 Honda Accord LX Station Wagon, since I got it, 21 years ago. I started doing my own vehicle maintenance and repair in 2001, after I got screwed over on 2 tune-ups on my 1991 Winnebago, on a Chevy chassis. Every time I got it back, within a week it was running just as bad as it was before I had the tune-up done. To be brief, I hung upside down in the passenger seat, pulled the distributor cap and rotor, and the spark plugs, and discovered that the plugs were original, from the factory, ( they had blue paint on the bottoms. My dad worked for GM, and told me, once that is how you can tell if a used vehicle has had general maintenance; paint on the plugs, not a good sign unless the vehicle is only 2 years or less) ! The distributor cap was cracked and the ignition points were black with carbon! Guessing it was original, too! I was a single mom, angry as ----, and vowed this would never happen again! As it turned out, this model and generation of Accord was one of the best for high milage with few major repairs, over time. Easy to repair, too. I am also fortunate to have a son that has been an assistant manager in Honda parts, for over 20 years. I considered getting a newer vehicle, a couple of years ago, but the particular Honda Odyssey I wanted was never for sale, at the priceI was looking for. Now that used cars have doubled or tripled in value, I've decided to fix my wagon up, and keep driving it. It only has 214,000 miles on it. My youngest son had a 1991 EX Wagon with 500,000 miles on it. He sold it to another one of my son's, in 2007, when the FIT came out. That '91 Wagon is still being used at my son's vineyard, 14 years later, so I'm sure, if you keep making those great DIY maintenance and repair videos, for the 4th generation Accord's, I can keep mine running like new. I was fortunate to find used one that was not driven where they use salt on the roads. Right after I bought it, I got recruited to work in South Texas, and direturn to the Midwest until 2014, so, outside of the Honda, "oops" rust, on the rear quarter panels, there's very little body rust. I'm going to learn how to use a MIG welder, this summer, so I'm hoping to do some fixing on the body. Sorry for the long comment. Keep up the great video's!
I freaking loved reading this comment... What a cool story you have. You remind me of a cousin of mine, one of my favorite people. Rock on lady! 🍻
I just tried it today. My accord is running a bit smoother now, and seems to start better as well. Didn't do a perfect job apparently, but ended up with better than what I had before. Maybe there are other problems keeping it from running really smoothly, but I'll watch your other vids and get that all sorted out. Thanks for the help, Eric!
@eulluisgtr34 Glad I could help, thanks for the comment. Adjusting valves can take some getting used to no matter what tool you use.
I was kind of nervous about doing a valve adjustment, hence searching for and finding your video. But this is almost exactly like changing and touching off tools on a swiss lathe, which I can do in my sleep. I am still going to watch a few more times and find more instructional resources but I am way more confident now. Thanks.
@EricTheCarGuy I figured everything out and it runs better than ever. Thanks for your help!
Made all the difference, at high rpm. Super smooth and a little more power!!! Thanks so much for the info!!! 263000 and it runs like new!!!
Great video! seems easy enough. Looks like the trickiest part is making sure cam lobe position is correct but I think I can figure that out by moving it back and forth etc... Very thankful Eric! Cheers
@shihanctb Glad you enjoyed it, thanks for the comment.
Great video, Eric thanks for the knowledge. Your videos greadly help me keep my 95 accord alive
Great explanation and illustration. I just replaced spark plug tube seals on my '96 Accord and am headed outside for valve adjustment. Thanks!
@MartyOs1 You can do this one cylinder at a time and not have to redo the adjustment however experience has taught me that it's easier to make sure each lobe is on the base circle when adjusting.
I am 15 years old....and i love working on cars with my uncle...and you are teaching me alot of new things....thank you!!!!!
Thanks gave me the confidence to successfully adjust mine :) turned a paranoid beginning into success.Thanks for youre easy go manner,makes for better understanding.
I just run through the valves in sequence which means bouncing from cylinder to cylinder doing intake valves on some and exhaust valves on the other until all valves have been adjusted. I like to have the lobes 180º from the rocker on the valves that I adjust but as long as you are on the base circle you should be OK. It is possible to adjust all valves with just one revolution of the crankshaft, I just choose to do it my way based on experience and my comfort level.
Me and my 91 prelude thanks you for this video. Words can't describe how nice it is not hearing the engine clattering anymore.
This man is on point with allll of his videos. Shoutout to you. Great video yet again. @EricTheCaGuy
Thanks Eric! You the man when it comes to needing a video for a car repair job.
@myadler Sounds like replacing it would be a good idea then. If the drive belts are in that kind of shape you might consider doing the timing belt as well.
Hi Eric, been watching your videos for years now and only just subscribed. Always great content and attention to detail. Keep up the hard work and quality videos. Much appreciated.
Richard.
@TheBmag360 That is something you develop over time, remember this is all about the feel and experience plays a large part in that. As for your noise, it's critical to make sure that you are on the base circle of the cam when doing the adjustment, if not your readings will be off.
@X2N18 I've actually taken a little bit of automatic transmission fluid and pored it into the intake while running the engine about 2K. This seemed to work pretty good. I wouldn't do it too much however, you may foul an O2 sensor.
@YOUNGaz11 No, many other manufacturers call for adjusting the valves when the engine is hot meaning just after you shut it down, Honda's however want the engine cold. The reason for this is that the expansion of the metal changes the clearance as the engine warms up and will effect the measurements.
@bigav27 Glad you liked it, thanks for the comment.
@TheArson7 I love comments like this. I'm happy to help, thanks for the comment.
@MyLATim Sometimes you do have to chisel them out. You might also consider replacing the seals that are further down in the spark plug tubes as they may be leaking too. I have one coming in soon and hope to make a video of this operation.
I have an old Renault 4L and it smokes only when going uphill. after a lot of research I figure it could be the valves. going to give a it a try and set the gap after watching your video. thanks for being so thorough with your explanations, you make it easy to follow
Thank you for making the comment about the spark plug tubes. I had no idea they were threaded. I'm doing a updated head swap on my Honda.
@hondaslave The idle air control valve not the intake valve. You can remove it from the intake and clean the screen that goes to it and it helps smooth out the idle.
@nightmathzombieethan No worries, glad to have you aboard.
@joeaccord23 Glad I could help, thanks for the comment.
I think you can do it with a scanner on most vehicles. If there is an issue with the idle you could disconnect the valve but for the most part you are only disabling the ignition momentarily and it shouldn't adversely effect the vehicle to any great extent.
@myadler Perhaps not, if it's a manual and the wheels are on the ground you will need to put it in neutral first. I've also tightened the belt a little to make it work better in the past.
@Vova2589 Valve adjustments are more of a fine tuning service than a fix. As for MPG make sure your tires are at the correct pressure, your tune up items are good, cap rotor, plugs and air filter. If it's still getting poor mileage after that you may look to other places that might be causing poor gas mileage like sticking brakes or a driveline problem.
Eric I have to thank you for this video as it did encourage me to the valve adjustment on my accord, the same generation with the same engine (F23A1) as the one in your video...
HOWEVER, the way the Honda Service Manual tells you to adjust the valves on the F23A1 engine leaves the lobes pointing to the front of the car and the base circle towards the back, as if you have to adjust the valves with the lobes at a 270 degree angle (lobes pointing up being 0 degrees and turning clockwise). An easier way to tell if they're in the right position for each cylinder would be to take out the two 10mm screws holding the timing belt cover around the cam gear. The cam gear will have an 'UP' indicator on its side which should be facing TOP DEAD CENTER (or Up) for the valve adjustment for cylinder 1. When positioning the Up indicator, please keep in mind the engine is in the car at a bit on an angle and try to turn 90 degrees relative to the angle the engine is tilted in. Turn the crankshaft 90 degrees counterclockwise so that the UP indicator is pointing to the front of the car to adjust cylinder 3. Turn 90 deg CC again to make UP point down to adjust cylinder 4. Turn once more 90 deg counterclockwise to make UP point towards the cabin of the car.
I adjusted the valves to Eric's method and ended up with a very shaky, stuttering idle. I turned the car off and tried again the next day by the service manual's description and have my car running happily again. I may not be done since there is still a slight tick audible but less than before.
I didn't write this to crap on your tutorial Eric. Really, it did help in making the process much less nerve-wracking. I am only posting this so that others do not panic and think they broke something with their Accord and the valve lash is simply off
@Adrian McDowell F22A is SOHC, 16 valves, non-VTEC
Had to work on a totally different engine (Yama 250), but from your video I was able to determine where to measure with the feelers (valves were badly out of adjustment, zero gap (.003-.005 are specs)), so thanks a lot!
i love your videos. i been working on my 94 civic vx and restoring it back to its great milage. iv almost done everything i can on the car with your vids in figuring out its hesitation problem after warmup while cruising. if this valve adjustment doesnt do it im hoping a new distributor will
keep up the awesome vids!
Yes, I believe it was.
That was the best adventure I've been on, thanks dora!
Hello there, Mr. Eric. I have a '98 Civic with the D16Y7 engine, needs an adjustment badly. In other videos I've seen, the person takes the front left wheel off, sticks a very long extension in there to turn the engine over via the crank bolt. The few others that I have seen they don't even remove the spark plugs and they struggle a little despite the large wrench they were using. Glad I saw your method here! Smart idea. Thanks for another helpful video (even though this one's almost 5 years old). Keep them coming!
@Kennykid2002 Mine are Blue Point and I got them off of the Snap-on truck. You should be able to find long feeler gauges at most tool suppliers though.
@toyota339 This engine is actually an overhead cam engine. You adjust valves on solid cam systems. Cams are divided into 2 types, solid and hydraulic. 90% of what is out there is hydraulic and does not require adjustment, solid cams like this one do require periodic adjustment if it's an overhead cam system OR if it's a regular pushrod system, where the cam is located is not important the type is however.
That's great to hear, the entire reason I started making these videos was to save people some money, these are hard times indeed. Thanks for watching.
Lol no kidding, local shop charges $260. I bought the valve cover gasket(also came with spark plug gaskets) and the adjustment tool and feeler gauges for $30. This saved me $230. The stealership would of charged way more.
@nobo631 The more you do valve adjustments the better you will get and you will develop your own set of steps along the way, it's really up to you to find out what is going to work for you. Good luck.
@photo2u Valve adjustments take time to master don't expect to get it right the first time you do one. The rule is "it's better to hear them than smell them", meaning that it's better to get them loose and loud instead of tight and possibly burn them up.
@NETWizzJbirk I always use NGK plugs and never gap them, I visually inspect the gaps before I install them but the factory gapping is far better than anything you could do on your own.
@Luxxer1 It can help a rough idle but is not often the cause, for the cause you could start with the basics like a good tune up but also make sure the timing belt has the correct tension as a loose belt can cause a rough idle.
@drumist1989 Not all valves are adjusted cold for that very reason, in fact most of them are actually adjusted hot. I made the cold distinction because that is what Honda wants. Excellent point, thanks for your comment.
@dc007fan Honda ignition systems are specifically designed to work within certain parameters, alter those parameters and you ask for trouble especially when it comes to plugs. I've actually fixed many Hondas just by putting the correct plugs (and taking out the champion or autolite plugs) in and yes heat range has a lot to do with it.
I recently had to buy a Lawnmower (00 Accord Poverty trim) so glad you made these videos for me.
It is a good engine. It does have a couple of faults. One being the balance shaft seal that has a tendency to pop out and cause a massive oil leak, easily fixed with the retainer. The other is the oil leaks that sometimes develop at the distributor and oil pan. It will outlast the car in most cases.
Thanks Eric! Always great in depth explanations of the process
You should do one for flat tappet engines though (like old school chevy small blocks), I actually went through that process about 6 months ago and wished you had a video like this for that procedure!!!
@HellFireno88 It might be the valves, adjusting them won't hurt anything if you do it correctly, it's worth a try if nothing else.
Thank you Eric, you are an excellent person at what you do and teach.
Hey, just wanted to say that I appreciate the effort you put forth into making these videos. I know the time and work it must take beyond the jobs you do to make these and make them as well as you do. As an ASE certified Tech, I can tell you've been doing for a while and you really do know what you are doing. I'm working as an Instructor for a local Tech College now and some of my students have been asking about videos and resources they can access at home. I will definitely suggest your videos.
@707Mendo707 That could be a lot of things but start with the basics like pull any check engine light codes you might have. Check the plugs, wires, cap, rotor, fuel and air filters to be sure they are in good condition. It being a 1990 it's not sophisticated enough to register if it has a slow O2 sensor which can throw off the mix, we would sometimes replace those like a maintenance item in the days before OBDII.
@cheeseslinger Yes on some engines you can't put the feeler gauge between the valve and the rocker so you need to place it between the cam lobe and the follower.
@Q8ROTARY I think you will do just fine. Good luck to YOU.
Bro, because of you and the PLETHORA of knowledge you have provided me pertaining to my 98 Accord I have learned a crazy amount! I will continue to buy Honda because they are not only great cars, but I now have a frigin reference site to go to each time I have any issues. THANKS THANKS THANKS! Power through.
I am glad to know about this procedure now! It appears to be a simple, fun procedure, yet requires practice of course! If I come across somebody with a honda, I can inform them about this, and recommend your video.
Mike
@stonent I was just about to mention the Mitsubishi contingent of may Chrysler engines but you beat me to it. Thanks for your comment.
The thing to watch for on that engine is a loose timing chain, I've seen them wear a hole in the timing cover and cause an oil leak. If it is loose it will be almost impossible to adjust the timing since it will fluctuate so much. Listen for the chain slapping behind the timing cover when you rev the engine. This is probably more important than the valve adjustment really.
So i adjusted my valves, got new spark plugs and adjusted my timing. Took me like 4hrs but now my car is running smooth. It wouldn't have taken as long if i bought that tool that you have to adjust them. Thanks for the video eric.
1993 civic d15b7
My magnet found the fasteners just fine, they usually stay in the cover but cars don't always do what I tell them too. A ratchet would work just fine on the PS pulley, for me it's just easier to use my wrench. Thanks for the comment.
Best and complete repair video I've seen so far....Thank you
@sonofseasia I'm not sure I understand the issue but sometimes the screw gets stuck inside the nut and you have to free it in order to make the adjustment. BTW valve adjustments are an EXACT science if you get it wrong you run the risk of burning up the valves which means you will have to remove the head to replace them.
@dreadiel Even on other makes it's not often I find just the valve seals that are bad, if I do find bad valve seals it's often on a poorly maintained engine and other things are worn and leaking as well. Thanks very much for your comments.
@Perez19136 You should double check the under-hood sticker if you have one because if I'm wrong you could damage the engine. .026mm and .030mm, the smaller is the intake.
I've never had much luck with those. After working at the dealer and seeing what they use, it blows everything else away, especially electrical manuals.
@Perez19136 Sounds like perhaps a restriction somewhere, you might want to drop the exhaust at the manifold and then recheck it to see if the condition is still there.
I don't think there is anything like your talking about but I don't know for sure. Sometimes you just have to eliminate everything else and go with your best guess. I've tested the resistance on coils that were bad that tested good, I think the only way to know if a coil is good or bad is to observe it under load. Come to think of it an old Sun machine might work but I haven't seen one of those in years.
just came across eric the car guy first time seeing your vids and ive probably watched about 10 of them. Very informative and on the money thanks for your info and knowledge gives better ideas on how to go about doing the job its like ALLDATA on youtube lol keep up the good work bro
@DanielRemains Good luck and thanks for the comment.
wow i learned something today! Merry Christmas ERIC!
Water boils at 212ºF, seam is water that is above that temperature at atmospheric pressure. In other words steam is water that is hotter than liquid water. I recommend only using an OE thermostat in a Honda.
Your welcome, thanks for the comment.
@PVoyager If you have NGK plugs that's a good start but that engine is notorious for clogging EGR ports which will cause the misfire. Try cleaning the EGR ports first and see if the condition still exists. Valve adjustments are more of a fine tuning thing and don't normally cure a problem like a misfire.
That engine is similar to this one but it has roller rockers and VTEC on the intake valves, the procedure is the same however, good luck and thanks for watching.
@valflyinf Good luck and have fun with that, it sounds like quite a project.
Thanks for these videos and the great help they provide!
Great Video! Yeah I've actually seen those kind of engine have leaks at the spark plug tubes a few different times.
@mrjost55 No, I recommend following the factory procedure removing hot fasteners may burn your fingers but should not be a problem for the engine.
There is a special tool that can be plugged into the cig lighter that will keep the radio memory. Never work on a starter or alternator without first disconnecting the negative battery cable though.
@OwNoHeDihen Yes, all replacement radiators (aftermarket) seem to have those. You can just unscrew them before you install it, if not don't worry about them.
@Collins328 I wish I could have posted your entire comment as my comment of the day but I'm glad I got what I did. It's one thing to be recognized by the DIYer that watch my videos but quite another to be recognized by a technician and instructor such as yourself, I can't tell you how much I appreciate your comment, thanks.
You could but keep in mind the measurement is done hot, this creates an interesting challenge when doing the job as well as the math that needs to be done to get the correct shim, get it wrong and your doing the job all over again.
I really like how you dont just skip over 'in between' parts, instead just fast forwarding so you at least see whats being done. Keep up the great work!
Good job eric.
I have a accord 1996 rare wagon my self.
The only one in Suriname..south america with a F22b double camshaft...
And when its hot, normal hot..
It shuts down..
I did alot like changing sensors, adjusting throttle, nothing helps much except for those sensors, they turned off the check engine light... so the last thing left is that adjustment....
Thanks bro..
Im tuned..
Stay dirty💪
@new14520 Honda used to recommend valve adjustments about every 30K, they have since amended that to just when they are noisy.
@ladabyturbo Yes and yes, if your going to go with a higher lift or even run a higher RPM you need stronger valve springs and as a result it will cause more stress on the cam. In short if you want to play you have to pay.
