good and easy explanation...thank you from Argentina...I am 72 and I think it helping me to repair my H CR-V 2000 . Not easy get parts.. thank you...
Thank you. A lot easier than expected and took care of a killing miss / multiple misfire codes.
Robert Gamble really glad it worked for you! Misfires suck
Always adjust the gap to the larger setting per the specs and the easiest way to be pretty accurate when you're doing this is to use the "go/no-go" method. For example, if the FSM tells you the gap needs to be between 0.011" and 0.013" then you want to make sure the 0.013" feeler gauge passes through but the 0.014" feeler gauge will not. I've been doing it this way for over 20 years( and I have 285,000 trouble-free miles on my '98 CRV) and it really takes the guesswork out of the procedure. I used to adjust/check the valve clearance every 30K miles but I've bumped it back to 40K the last couple of times since the valves were still well within specs when I checked them. None of mine were even close to being too tight at 40K but I made sure to adjust them back to the largest setting if need be.
Dude you're a walking miracle! I think i got to do this to solve my stalling when going into R or D from cold (along with several other things). People like you make the world go round.
thanks for watching!
Did it work?
I have the same issue with mine

I'd like to do a valve adjustment on my CR-V too having watched this. Thanks for uploading it!
youre welcome!
Good video and explanation of why the valve clearance decreases over time as opposed to most cars that increase over time. On a high mileage B20, you may run out of adjustment on one of the rockers. If left alone, it will surely burn a valve. The fix i created was to disassemble the rocker and grind about 1mm of material off the body under the ball. That yields +1mm of additional adjustment. See my video on this.
Thanks for taking your time to show us this. Great video man. Keep up the great work!
thanks for watching!
You have the best CR-V engine repair videos dude. Thanks a million for sharing your knowledge. SUBSCRIBED!
I really appreciate the kind words! Check us out on FB and Instagram, and thanks so much for the views and sub! Happy wrenching!
Thanks so much for the video. Very helpful refresher for adjusting my daughter's valves. I appreciate how slow and methodical you are in detailing each step of the process!
David S. Logsted thanks so much for the kind words and the view! Hope your crv lasts forever
Wow this engine is so clean
wish there more mechanics like you. especially in wv.
babe tucci thanks! I appreciate that very much
When I checked the valves on a CRV, the one exhaust valve was over-tightened.
It had been at the local Honda stealership in the past 6-months for an unrelated distributor issue. It was fixed after a couple visits, and due to the need for multiple visits, they threw in a complimentary valve adjustment.
I was like sweet, thanks for that! It drove alright for awhile but then started to exhibit misfires. I parked it for awhile then eventually checked the valves. The one exhaust valve was way over tightened.
This leads me to believe that the service technician could've accidentally or even purposefully over-tightened that one valve, which led to a likely burnt valve and literally no compression in that cylinder.
Now I'm trying to go through Honda Headquarters to see if they can resolve this issue as it seems to be not only a TSB, but also the fact that they performed that incorrect valve adjustment not too long ago.
If nothing can be resolved through them, I'll have to either pull the head and change the one valve and seals (hopefully) or change out the head for used/rebuilt one. Such BS. lol
That is pretty rough :( sorry to hear that. Definitely look at costs to complete the job properly and compare to swapping in a fresh JDM engine. I usually don't do head gaskets anymore, or repair heads. We just swap in fresh JDM swaps and end up with a better end product with similar cost overall. Check it out (depending on your mileage anyways)
All good :) just a bump in the road lol
I'm not sure if I will do that as we don't intend on keeping the CRV...just really trying to get it to run reasonably well enough to sell. It's a great engine, all the other cylinders hold great compression, it's just that one! :(
So, given that we want to sell it, we're either thinking of selling it as-is and taking a hit on the value of the car, or repairing it myself to the best of my ability, hope it holds compression after whatever I try, then hopefully sell it for close to its actual value.
If we were to keep it, I'd think about the JDM swap, but hopefully someone likes these things enough to do something like that if it were to come to that. It's got 220,000 kms on it, so not too bad. Just needs a bit of TLC :) lol
Thanks for the info and input!
yea u must watch out for them stealerships. anytime they service a motor u must take it home and tear it apart and check their work immediately! kinda takes the point out of going to the stealership doesn't it?

No doubt eh!
awesome video, thank you. just did my 99 crv. intake valves pretty good all around. on the exhaust side, i had 4 that were slightly loose (guesstimate .25mm), i had 1 stupid tight (had to turn the screw 2 full turns before i could even slide the gauge in there). that was cylinder 4...2 others were a bit tight, but probably within specs (.16..17), and the last was really loose (guesstimate .30mm or greater, cylinder 1).
chasing a p0304 and a p1399 codes. i replaced the spark plugs with NGK PZFR6J-11, which is really the only spark plug you should use on the B20...doing that cleared the p0304 once i gapped them correctly.
the crv only has 100K miles on it, and i've never had to adjust valves over the span of 20 +/- hondas, including a '98 civic with 360K on it.
advance auto parts has a PL branded gauge in stock, the only thing that sucks is the smallest gauge on it is .203MM (ideal for exhaust valve adjustments, but useless for intake valves...had to borrow a gauge).
5:35 off-lobes can help indicate which cylinder at TDC. Lobes pushing down means valves are pushed down, aka that cylinder is not TDC
Set exhaust more loose side cause tendency to end up too tight.
10:20 test drive
Hey guys,looking for alittle direction here.Just picked up a 1998 cr-v
with 170,000 on it,had a stumble at ilde and check engine light on with
random misfire,cyl num 1 and 4 misfire and lean bank 1 codes.So I
pulled the the plugs and it had oil in the wells.Started with oil
change, new ngk plugs,replaced the valve cover gasket,and since the
cover was off went ahead and did a valve adj. since it was a little
loud.started it up engine was alot smoother and engine was quiet,Drove
it for a hour or so and got the stumble back with 6 misfire codes ,
random misfire, cyl 1,2,3 ,4 and any cyl misfire,So pulled it back in
the garage and did a dry comp.test,got cyl
1/170.cyl2/168cyl3/158cyl4/171.
Only thing i noticed was that harness connecter for the dist is stuck
and the plugs where bright white still and dry.Don't want to threw the
parts bin at her haha!
What did you do for the intake side just the stock .10 or did you add .02
Which direction should I rotate the crankshaft to get it on the tdc marks.? Clockwise or anticlockwise?
I need help. I have 98 Honda CR-V I got the intake valve adjusted but the exhaust valves I want to leave a little lose . My oem is 0.18 mm so I would go to 0.20 or 0.16mm . Witch one of the adjustment numbers would be best for the exhaust .
Shawn Roberts I wouldn’t go tighter than 0.18mm, 0.20mm works great too. If you’re new to this aim for 0.18mm, and make sure the 0.20mm won’t fit. Like a “go-no go” adjustment.
Mister, i would like to ask
If i have b20b engine with the camshaft pulley is rusted..
Is that indicates bad situation?
Just picked up a 98 crv, and its missing bad enough to make the check engine light flash, and when i cranked it with the plug wires out it sounded like a cylinder was down on compression, gonna try this trick and hope the valves are just really out of adjustment
thanks for watching! hope it worked out
Hey man got a question are my valve bolts apost to be loose like the bolt is wiggly but there all tight
Thanks for the video trying to help a single mom that is going through some hard times she has codes P0302.303,304,300. And P1399pnd 87k on car has new spark plugs but it’s running rough like it’s going to die, starting looking at the codes but almost everyone says prob need to adjust the valves , wAnted to see if there is something i can tackle myself so i can help her. Do you think i should start w the valve adjustment or ignition coil and spark plug wires , does the gasket on the valve cover needs to be replace every time , thanks again i learn a lot .
you shouldn't need to replace the gasket if it isnt leaking currently. Take a look at the spark plug gap, condition of the cap and rotor and of course watch the video and adjust the valves. good luck!
Ronin Motors thank you
Thank you very much
Hi there, my old 2001 mk1 CR-V has a B20z1 engine. Now it has Honda servicing up to about 2014 by the previous owners- I can't see any documentation that the valves have ever been re-tweaked or even the timing belt changed from any of the receipts I got with the car. Just fluid changes, break pads etc. It has it's 150'000 miles on the clock but the engine sounds fine to me. But what do I know as I'm a total novice at this. So I was wondering what your advice would be- I'm probably not going to open the engine at this early stage- only had her a month! But it's a great car and I'd like to keep it around for a while. Should I take her to a Honda garage to get it checked or could a good non Honda mechanic check the valves?
Deaner Hockings - Reptilian Hunter taking the valve cover off to inspect the belt is pretty non invasive. You dont have to take it to the dealer but someone familiar with Hondas can adjust the valves. Maybe on your next service suggest that they adjust them and inspect the belt for wear. B20’s dont really snap belts often so I wouldnt be worried. Do adjust the valves in the next 5-10k miles though. Cheap insurance since itll only cost about $100 to do.
@@roninmotors7466 Gold! Many thanks for your time, advice and your videos.
Where are u located at? I need a good and honest mechanic like u..
Centerville, Ut but sadly we aren't a mechanic shop
My rocker arms got mixed up, does it matter how I place them now? Is there a way to figure out which one goes where?
The Comment it does matter, but if you do a valve adjustment after, you can put them anywhere. Thanks for watching!
Hey! Awesome video! Question ... where's a solid place to get a reman'd cylinder head online? I've never done this valve work before but my '01 CRV SE has 2 cylinders misfiring now and I think I'm going to tackle it myself.
We usually take them off of our JDM engines. Im not sure around you
@@roninmotors7466 Okay thank you! I'll see if I can find someplace here in Chicagoland or online to get one. I haven't ever taken off the valve cover on this thing, so we'll have to see what's up under there before we decide what to do. Cheers.
Thanks for the informative video!
Unlimited Potential youre welcome!thanks for the view!

Just wondering, you're referring to "off-lobe" and "on-lobe"..does that mean that Top Dead Center is "off-lobe"?
In the service manual, it states that the cylinder should be at TDC for the valve clearance check.
Just curious if what the deal is on this? thanks
by "off lobe" I'm referring to the humps/lobes on the cams that open and close the valves. Starting with TDC, you rotate the crank and do each cylinder in the correct order. 1-3-4-2
Thanks, I just wasn't sure what the relation was between off-lobe and TDC.
I was like "does TDC equate to being off-lobe?" but you were checking the valves for more than one cylinder at the same time?
As you say in your reply, start with TDC, rotate the crank, follow the order 1-3-4-2.
this guys cool lol . Hopefully you found the motivation 😀
Which feeler gauge did you use for your intake side
How resilient are these engines? I just bought my friends CRV, she’s been driving it for about a year with it misfiring. I tried adjusting the valves and no compression to cylinder 4. Think the valves are stuck open. Hope I can get away with just replacing the head…
Do you only do the exhaust valves? My 98 is throwing a misfire cylinder 4 so I'm looking do this next weekend
Jpadilla05 no you check both, I give both ranges in the video. Typically the exhaust will be the only ones requiring adjustment however. They are the important ones on a B20 for misfires.
Ronin Motors thanks for the quick reply, also while im in there do you know what compression sgould be around on these engines?
199psi new. anything above 150-160 psi with no big variation between cylinders is fine.
Hello honda Master,, i'm working on a 1999 Honda CR-V having two codes driving me crazy do you think by ajusting the valve will fix it ?? Please help p0172 & p0175 & p0170 witch all say system too rich condition,, thanks for your help
adjusting the valves is one of the last things to do for this code. couldn't hurt. clogged fuel filter? stuck fuel regulator or bad? fuel feed line issue? fuel pump efficiency? fuel return line clogged? many other steps to check first for these 2 codes
Okay so i have a 1997 crv and i have misfire codes for cylinder 3 and random. I want to order a feeler gauge on amazon to do it my self but when i get it and start adjusting should i use measurements .008 on the exaust side and .005 on the intake side ?
in the video I show where to see the specs under the hood. Also be aware of the difference between inches and mm. Intake=0.08mm-0.12mm, exhaust=0.16mm-0.20mm......inches are Intake=.003"-.005", exhaust=.006"-.008". I prefer to set intake more middle of the range, and exhaust on the loose end.
Hello, good morning, Very good your video. I have a CRV, Motor B20Z1, it happens that when it heats up, it turns on the injection light, and it doesn't start anymore, only after it cools. I've even replaced the ignition module and the main relay. Have you caught this case? can give a strength of solution. Thanks, and I'm already a follower of her videos. Rio de Janeiro.
So you don’t worry about Top Dead Center for each cylinder while making the adjustment? Just as long as the lobe is pointing up?
I was wondering that too. Any answers?
Hey i have an issue i was going to adjust the valve on my b20b because my engine making lots of valve noise and i notice the bigger bolt under the valve adjustment bolt is loose and i dont know if i can just tight them by hand or anything… wish you can help me thank you
Hi, my crv also does that belt squee. l was wondering if you know what causes that.
yes. bad belt or too tight. adjust it
World this be the same for b20b ?
I jacked up my spark plug thread. Mine idles a little rough and not sure if previous owners adjusted valves. So will that help idle? I have no codes and mine is a 1997 crv.
it can help for sure, its not a cure all though.
probably needs a tune up
Ronin Motors I had adjusted at honda. Helped a little but still slight rough idle. I changed coil cap wires plugs air filter timing belt. Ran great and drove 7 hours straight but the idle is killing me.
HardCorps88 Marine Have you done a compression test? Verified fuel pressure at idle? Lastly you can check the IACV and FITV. Clean em etc....another guess would be a leaking gasket like intake gasket or vacuum hose.
Ronin Motors checked hoses with carb cleaner but not compression test or fuel pressure test. I did change fuel filter just in case. Thanks for suggestions.
HardCorps88 Marine anytime man, good luck and happy hunting!
Hey man. I've got this issue where, once my crv warms up it stalls out. If its cold the idle is high obviously keeping it running. Once its warm and i come off the gas she bogs down and stalls out. Or if its warm and i blip the fuel same thing. If not it'll sit there and idle. Iv'e only got 2 codes. P1456 and PO135. That doesn't give me codes indicating valves need to be adjusted right? I was thinking maybe fuel filter was clogged because of how it was acting. Please let me know what you think?
.
Check your:
Fuel fill cap
Vacuum connection
Fuel tank Fuel tank pressure sensor EVAP bypass solenoid valve EVAP two way valve EVAP control canister vent shut valve EVAP control canister EVAP purge control solenoid valve
You obviously have some fueling issue and/O2 stuff going on. Also verify mechanical timing and ignition timing. also read your plugs....
@@roninmotors7466 will do and will get back to you thank you!
How much torque do you put on the retaining nut
hand tight or 16 ft/lbs
Is the bent feeler gauge necessary or can I use a flat style?
you can use either or even bend a flat one.
Do the adjustments need to be done in the same order as the firing order? 1,3,4,2?
You should, I just did it out if sequence and now I’m gonna do it again in order 😪
Just found your channel. And I just subscribed. I keep getting a IACV code. And it's been replaced already. And it still has a weird idle. Only does it once I drive it and come to a light. Idk what else to do man. Also, if I leave it idleing. And go to drive off. It'll blown out some smoke. I'm just out of capable options. Idk if it is something you have come across.
Armando Acosta if you keep getting the same code you need to check out the wiring or try another iacv, ive had bad replacements. The aftermarket ones suck
Thanks alot man. I'll try that out!
Great explanation on adjusting, what brand or where can I buy those bent feeler gages that you have?
Kyle thanks! Most likely theyre from Home Depot or Harbor Freight. Most my tools are, i love the cheap stuff
I like cheap too, I will keep checking, my HFT only has flat and Amazon has bent but not in the increments I prefer. Thanks for the reply, HD next.
How do you tell the difference between valve noice and injector noise?
Great question! Grab a long screwdriver, place the metal end on the injector and put your ear on the handle. This will allow you to hear the injector. They shouldn’t be that loud.
@@roninmotors7466 thank you sir.
How did you turn the engine or moved the cam shaft in position
You use a ratchet and socket on the crankshaft. That’s how you rotate any engine. Good luck!
I didn't need that special tool with the open 12mm head with the wrench thing when I adjusted the valves...I think I simply used a wrench>?
just a wrench? no flathead as well? This tool makes it easier and quicker, but you can use a 12mm wrench and flathead.
Sorry, yes definitely a flat head too :)
It would be nice to have these various special tools! But, I ain't a mechanic, just working with the basic tools and lowest cost possible :P
Thanks to videos like these, I'm able to complete various repairs, saving me a small fortune! So a major thank you again!!!
you're very welcome, I'm trying to get better at making them to help more people. its tough, just like learning to adjust valves, it takes practice
What would you charge to swap in a JDM motor? Parts & labor
We don't work on customer cars sadly :(
Great video! thanks. I have a problem on a single Intake Valve , on a single rocker arm, its strange , its recommended to grind a rocker? that valve wont let me in the feeler gauge numbered 0.005 is the car shop Valve Job not performed correctly? the guide or the seat of the valve is whats missing to be checked to avoid grinding anything on the head? really worried about what to do! thanks again, hope to receive a reply!
sorry for the late reply's but your idea is on the right track. If the valve seat has recessed too much that may be your only option without removing the head. Some have had success grinding the rocker arm. Is it ideal? no. But you gotta make do sometimes. Oddly the intake valves rarely have these issues, so I would not.
16 dislikes from money hungry mechanics.. lol
I never noticed it had 16 dislikes lol bummer. Im always looking to make better, more informative and more helpful videos. Shorter, clearer and to the point if possible. I wish they would have left constructive criticism instead haha
@@roninmotors7466 21 morons exist here, 3.8 billion exist on earth : P ...don't sweat it...lol. your video was the only guide i needed to tackle this with relative ease.
Maybe the dislikes are because you shouldn't have to do this. I've never really heard of cars having to have a valve adjustment let alone every 30k miles. Ridiculous, especially out of a Honda. My girlfriends 2017 is at dealer for this exact thing. They have been trying everything, even replaced all fuel injectors,, now gonna do valve adjustment at 65K miles. Good thing it's under warranty! Ridiculous! Also having to change the crap diff fluid every 30k and Trans fluid every 30k CVT trans is ridiculous too. Too much maintenance, I wouldn't have expected this much maintenance on a Honda.
Can this procedure solve it? thankful.
Good video man . I have a question about my b20. If i have no compression on cylinder 4 would that be valve adjustment problem or a mess up valve? Thank you in advance.
Probably a burnt valve due to lack of adjustment
I notice you used a spacial tool to hold the nut, can be done with just a spanner?
absolutely! that's how most people do it honestly
For what years crv is this
why are you checking with a .2mm when it says .10+-.02mm ?
luxaeternae might wanna take another peek, Theres a difference between intake and exhaust specs. Honestly for the sake of the video I could have used a popsicle stick and it wouldn’t have mattered. The camera isn’t going to pick up thousandths of an inch or show feel. The specs are in the description.
Could you get me a price list !? I’m in search of a replacement engine : b20
12mm valve adjustment tool
14mm ratchet/ wrench
Needle nose plier
10mm socket
Feeler gauges
19mm half inch drive
Black rtv silicone
That’s all you need! A rag & gloves too
You definitely don’t need the valve adjustment tool either, you could use a flathead with a 12mm wrench to hold the nut
I heard the measurements were printed wrong on the sticker under the hood.
yes and no, they issued a service update later on opening the exhaust side a bit. with the -/+2, you adjust on the looser sides for exhaust to be safe. same as the service update issued later
Please sell me one of those engines lol been going insane trying to get my 99 CRV 2B20
tell me about it! importing is kinda shut down at the moment
Where is the valve adjustment how-to?
in my videos
12MM is the valve adjustment tool size.
Show. Bom dia.
Great background music. Also I did 004-005/007-008 cold, you think I fucked the pooch?
You don't explain so clear, why you use feeler gauge with same camshaft position?
You can watch the videos but just don't call this gentleman at his shop
name of parts needed?
valve adjustment lock nut tool? google dude lol or a 12mm wrench and a flat head
Nece motor
Will this cure my rich in bank 1 p0172
Pretty sure that's a timing belt issue, had the same problem in my 01 crv. I was literally off one tooth and it threw the code! It needs to be perfect
@@ownd2252 did it fix the issue ?
@@julianpenner-cloutier1079 Yes it did! Be sure to have both arrows facing straight up otherwise if even a timing cam is off by one tooth on the belt it will still not pass smog, I recommend getting the bluedriver obd2 scanner to check if it will pass smog. It comes with a presmog software that will show you if one of the O2 sensors is rich or not (it shows all of the O2 data). Another note is to replace the sensors, it was awhile ago so I dont remember which one exactly but they should be cheap. Hopefully this helps and if this does fix the problem update us in the comments!

Appreciate the feedback. Youre welcome to make a better one improving on what I left out?
