What are the chances that your "average joe" tech at a dealership is taking this much care to get the valve lash properly adjusted. Hah, maybe 1 out of 10 will do it right.
Hopefully this video can help increase those odds!
~Mike
Thanks, Great video. After watching your video I performed a valve adjustment on my 2006 Honda 3.5 (ridgeline with 200K miles). Took most of the weekend to complete the project. Since completed I no longer have random misfire codes, misfire cyl 1 -6 codes and no more P2279 codes. I was shocked at how tight my exhaust valves were. Also cleaned intake manifold, EGR valve etc before reassembly. Runs like a champ again.!!!
Hey Tim, thanks for watching! I'm glad you were able to tackle this thing on your own! Nice!!! Glad you got er' running well again.
Mike Becker, Senior Technical Instructor
Is this specs he gave out same for 2016 odyssey? Mine at 100k misfire cyl #4
It was nice of Honda to include the number of the cylinder on the cam sprocket, pretty handy. We ask so much of our vehicles these days so engineers have to pack everything in close quarters. Great job Mike. If I had this engine I'd feel comfortable taking on this job now.
I agree Wyatt. That was super handy! Great to hear that you would be comfortable performing this job now, my job here is done :)
Mike Becker, Senior Technical Services Instructor
By far one of the SMARTEST groups of designers !!!
@@GoTechTraining THANK YOU THANK YOU THANK YOU !!! THIS video saved my truck that “can’t be fixed” !!!
Ive a 2006 Honda Odyssey with a random misfire. It happened because I over-filled the engine oil. The instant i started the car...the engine light came on. I took it to the Honda dealership for repair. I requested an oil change and a code read. They pulled the code, said it was a misfire in #4 cylinder. Charged me 380.00 for a spark plug, coil pack and labor. They called me..said the car was ready. I picked the car up...and driving it out of their parking lot, the engine light came back on. I left the car with them again, they called me the next day and said....they pulled the code and now they say it has a misfire in cylinders 1,4, and 6 and want to charge me 1600.00 to change all remaining spark plugs and coil packs, and told me even with that...the car may not be fixed but it is a "starting point".
Welcome to the stealership business model
Hello, I have the same problem with Odyssey 2005 and valve adjustment did not help. I checked the fuel pressure - 55 PSI, pressure in all cylinders - 13 BAR, replaced the ECU, replaced coils and spark plugs, checked the installation. In ECO mode, there is still misfire on all cylinders. In permanent error mode the problem does not occur. Will you help??
Had similar problem. All the UT videos did not help. Adjusted valves and cleaned throttle body. Turned out I needed scanner to do a throttle body relearn. Bought Foxwell NT530 scanner with Honda software $160 and nailed it in 15 minutes. That software mirrors Honda scanner.
I have a 2004 Accord V6 6 Speed Coupe. Exact same motor. Just a 3.0 J30. My car was misfiring like crazy on startup, and would run really nice when warm, I usually do my own work, and I have not done a valve adjustment before and it took me about 3.5 hours. I started at 7: 00pm and was done at about 10:30 p.m. car seem to have so much more power and runs so much more smoothly. And it did not misfire when I started it from cold afterwards. So hopefully this fix my problem. I don't think the valves were done on my vehicle before because my exhaust valves were so tight that I could not even get the feeler gauges in. And the intake valves were loose and floppy. Such a big difference now
Wow, you did it without the special tool. You're a beast! On to part 3. Thanks!
Man, special tools are just a thorn in my side. If I can get away without it I will. Sometimes there just isn't a way though.
Mike Becker, Senior Technical Instructor
Maybe a dumb question but is this what causes the engine to sound like it is tapping? Mine odyssey has a tapping sound when it runs. If this is the case then I will try to do this.
I wish you would work on my Honda odyssey 2006. Don't know where you are located.
Hey Anei, thanks for watching! I'm in Wisconsin.
Mike Becker Senior Instructor
Amazing videos on this topic, thank you! I just finished our 08 Pilot, same symptoms, 192k. On it, all intake valves were loose (~0.011) and all exhaust were tight (as low as 0.004). Adjusted to 0.008 intake and 0.013 exhaust. Seems to run better, but still an occasional hiccup. Oh, and I did not remove the PS pump to get that harness out of the way on the back cover, and it was a major pain to get in and out of there!
Hey Mark, thanks for watching! Double check the EGR ports. Also, ignition coils are pretty common if you are still getting a misfire.
~Mike
I love watching your videos, they are very educational, some of these videos will be useful for me someday…
Great work Mike and I am sure that you got it fixed and looking forward to the test results. 😀👍
Hey Terry, tonight will be the reveal on if it's fixed or not. There was definitely a problem here that was solved! Thanks for watching!
Mike Becker, Senior Technical Services Instructor
Can I use a different color tape besides yellow to block the intake ports when adjusting the valves? That color doesn't match well with the design on my new pair of yoga pants.
Haha you can buy leopard print duct tape, downside is it always leaves residue!
Mike Becker, Senior Technical Services Instructor
Ok thank you for the quick response. bahhahaha!
I am the faster responding guy out there! ;)
Mike Becker, Senior Technical Services Instructor
Standard duct tape grey. You can't go wrong.
Hey there. I enjoyed your video and have a question you may be able to answer. I have a 2010 Odyssey that has what seems to be valve noise. It has 70000 miles and has been serviced regularly. My mechanic did a valve adjustment(and rocker arm retorted) and did not find much amiss and of course the noise is still there after reassembly. He noted that the front head was discolored like in you video and the rear one was super clean. He suspects that the front head was swapped some where along the way, although I know it has not been. Do you know why the front head would be discolored like that and not the rear if they are of the same age?
VCM - Variable Cylinder Management. These Hondas with VCM shut down the front bank for ECO mode. My understanding is this causes oil to blow by the cylinder rings and causes lots of discoloration in the head. Even worse is it causes premature wear of the front cylinders because the cylinders are not being oiled and cooled properly when they are shut down. Look up Honda VCM problems for more info.
Late to the party, but I am going thru this now. Pinging/tapping on startup, calms after warming up. 2006 Odyssey with JDM 3.0 replacement J35A1 engine (same specs). I have done the valve adjustment on this and the original engine with varying degrees of success. Each time I adjust, the clearances are off a bit.
Best advice I have found is to take a GO/NO approach to valve adjustment.
Intake (.008-009) check with .010 and .007 exhaust (.011-.013) check with .014 and .010
If the feeler gage goes in, you need to adjust, otherwise it is okay.
A major pain is getting the feeler into position. I would recommend first cracking the lock nut and backing off the screw for easy insertion, then inserting the feeler. Then lock it down with the feeler still in position. Then test for drag. Pulling it out and trying to reinsert is not necessary. However you do need to recheck the adjustment so rotate the engine twice and recheck clearances. This helps ensure you did not miscount the cylinder. Easy to do.
I have white smoke from exhaust pipe. I have the following codes: Front air/fuel ratio sensor bank2 sensor 1 heater system malfunction P0154, P0300, P0306, P0305, P0304, P0303, P0302, and P0301.
I changed the front senor hoping it would change the white smoke bit it is still present. I am considering cleaning my fuel injectors. The car is rough idling. What else can be done?
Replace head gasket
Honda can be smart and stupid at the same time. Why are they using 1960's technology still? Did they ever hear of hydraulic lifters?
Hahah yeh, right!? Not sure why they stuck with it...maybe "if it's not broke, don't fix it?"
Mike Becker, Senior Technical Instructor
Absolutely the best video on this topic. Thank you!
Thanks a ton Sat Sonic!
Mike Becker, Senior Instructor
What are the torque specs to put the cover back on your never said it
Heather, spec for the valve cover bolts is 8.7 ft lb.
Mike Becker, Senior Technical Instructor
Tell the owner to change their oil on regular basis those rockers look very discolored as well as inside the valve cover
Hey Swav100, this customers only owned it for about 20k. Hard to say what the previous owner did. Discolored sure, but overall it looks alright for 210,000 miles!
Mike Becker, Senior Technical Services Instructor
I haa 2004 honda oddysey with the same issue, is there a torque spec for the lock nuts? First time doing this
Hey Gabriel,
I show a torque spec of 14 (ft lbs)
~Ryan
Thank you very much!
Ryan, thanks again! after 9 months and 9,000 miles later, my 2004 honda Odyssey issues are gone, with no codes and no oil consumption, I did have to mention I also cleaned the intake, which had a lot of hardened soot, great video!
I have a 2005 Honda Odyssey 207,000 miles cylinder number 5 has a misfire I replaced the spark plug I replace the coil pack and still the same result no change there is a problem with when it cranks over it sounds like it jumped timing but I had the timing checked and it did not jump timing on the spark plug there was Heavy oil consumption any ideas what's wrong with my engine
Hey Timothy, so you've looked at a spark issue. Next thing to check would be a fuel or compression issue. Could be bad piston rings causing the plug to foul out with oil?
Mike Becker, Senior Technical Instructor
Great video..I've had my 2006 Honda Odyssey To 3 Mechanic Shops. Code reads misfire on cylinders 1-6 plus bank 1 to rich next to backside of motor. When you first start it up in morning it doesn't seem to shake as much..but after a few minutes it noticably shakes..but when on interstate it does great. But also it has a hard time pulling big hills. Honda was 3rd mechanic shop I took it to. They seem to think it maybe could be needing valve adjustment.. coil packs are good, spark plugs are new. Also I've run 2 cans of sea foam through it. Do you think it's a big possibility it's just needing a valve adjustment? Also will hurt engine running it like this until I can get fixed (if it needs valve adjustment) It has 265,797 miles. Thank you🙏💯
Hi Wes,
Thanks for watching! With a 265,797 miles, there is a good chance your engine is in need of a valve adjustment. I would start by measuring engine vacuum at idle. If the valves are out of adjustment far enough to cause a poor running engine, it will usually show up on a vacuum gauge. Look for a steady reading around 17-21 inches of mercury. If your readings are low, I would suspect valves may be out of adjustment.
Ryan W, technical Instructor
@@GoTechTraining Hey there. Thank you very much for info ,🙏💯
This is great! Thanks, I’m planning to do this job in a few weeks once it warms up on my 2003 Honda Pilot with 217k miles. One question, how do you rotate the engine? You mention something about the wheel being off, but I missed how that works. Thanks!
Hey Mike
The easiest way to rotate the engine is from the bolt on the crankshaft that holds the harmonic balancer on.
Hope this helps!
~Ryan
What do I do if two nuts on the rocker arm are missing someone told me to drop the oil pan and look for them there?
Check the muffler. Bet you'll find them in there.
@@timault8209 thank you.. but found them in the oil pan..lol
Excuse me, I have a 2006 Honda Odyssey and I already disassembled it to adjust the valves but I don't know what measurements it has. Could you give me that information please?
How much should that cost at a honest shop
Hey, labor alone is quoted at 4.3 hours just for the valve adjustment. Add in parts and you're probably around 1000$
Mike Becker, Senior Technical Instructor
What a joke, this really irritates me, why couldnt it just been s fricking coil, or plugs....NOPE! IM DONE WITH MY HONDA ITS ABOUT TO BE SCRAPED
Sister bought a 2009 Honda Pilot from a used car lot, Check engine light came on right when she got home. 5 cylinders missfiring, this has to be the reason right??? car drives fine.
Mine was a huge mess,someone had put on new gaskets with plug seals backwards,every valve was tight so I'm cleaning up a MESS
great video. It was very informative and in depth. I really appreciate you making. I did have a question as to what you were turning to move the dial to line up for each cylinder. You never showed that. Thanks!
Hey Jason, thanks! I was turning the engine over by turning the crankshaft pulley bolt.
Mike Becker, Senior Instructor
@@GoTechTraining thank you
Das good
I cant believe Honda still uses the mechanical valve adjustment. wonder why they didn't do hydraulic lifters
I know John, right! Crazy....I guess if it's not broke, don't fix it? Overall that 3.5 is a great engine....just needs a little extra maintenance love. Which is great for us, maintenance=$$$
Mike Becker, Senior Technical Services Instructor
Honda knew this design was subject to valve seat movement. Hydraulic lifters couldn't compensate for the amount of movement. Also, look at the design of the head....gravity/angle can affect hydraulic lifters over time, and they need more oiling than this design. At the end of the day, hydraulic lifters that were up to the task, and additional cylinder head engineering would have cost Honda money, and gone against the planned obsolescence narrative. It would also not be beneficial to technicians.
Excellent video. The only thing missing is taking the scope measurements after the valve adjustment to document that the timing is now in the ideal range. I just performed this maintenance on my EX-L. I observed that all of the exhaust valves on front bank of cylinders (4, 5, 6) were all 'tight' and needed adjustment. Only one of the exhaust valves on the back bank (1,2,3) was tight. A logical assumption would be that rear bank with the VCM are deactivated for a large portion time, and the valve seats don't get 'hammered' into the head as much as the non-VCM front bank do.
Hey Frank, thanks!!! I agree, that makes perfect sense!
Mike Becker, Senior Technical Instructor
I'm old-school and love my nano impact from Harbor freight. It's the length of a credit card and will zip off cv axle nut and small enough to easily get into tight area's like wheel wells to zip off brake caliper bracket bolt's. Also great for driveshaft bolts.
I’m surprised .005” difference in exhaust lash would cause a misfire.
Hey Sandra, yeh it doesn't seem like much.
Mike Becker, Senior Technical Instructor
You don’t do a novel every single day because you will need a air gun because those electric guns or battery operated guns when they fail they fail quick. There is going to be a day that you need an air gun.
It won’t take all weekend if you use battery operated guns all day long those engines are pretty simple. I know I’ve done too. Many of them is the most simplest that were made.
En que fallaste? No quedo el trabajo por lo menos ño reconoces
I replaced valves damaged when TB idler pulley bolt broke causing piston/valve contact. I did the adjustment off of the engine and check my work 3-4 times. After installing the head, bank 2, I now get a P0300 & P030[4-6] misfire. My fuel trim, both short and long, are in the neg for bank 2. Once warm, the car drives fine with no errors but, it is a little rough and still has neg values for fuel trim in bank 2. O2 sensors on both banks have similar readings up and downstream. Looks like I may need to check my work with the head on the engine. I'm not sure if the torqued head bolts may have somehow changed the valve adjustment. Is that possible? Great video series...thanks!
Hello,
I would start by doing a vacuum test at idle cold and see if it is in normal range.
~Ryan
Hi, mike. Quick question from a diy person here. I have both of my cilinder heads out of the block (on a table) I'm trying to adjust the valves before installing both back into the engine block. Can I adjust all valves all at once (given that all valves are close)? Again, both cylinder heads are out of the engine, sitting on my table. I remember you said at the beginning of video that valves have be close. Is it possible?
Hello,
Even if the cylinder head is removed, the camshaft is still installed and acting upon the valves. I would wait till the head is installed and follow the procedure to line up the camshaft in the correct locations to adjust the valve lash.
~Ryan
I’m curious to go in firing order or do you skip cylinders? Or does it not matter?
I don't see any reason you'd need to go in any specific order. It's just making sure the cam is lined up. If I remember right, I went off of the labels on the cam gear as I spun it around.
Mike Becker, Senior Technical Instructor
NGK Technical Training thanks for replying back and letting me know.
I just got a plug to locate behind the power steering pump after putting back the intake manifold 🤷♂️ not sure what I missed.
Hola mike what's the model #on the 1/2 inch drive cordlees gun?, I need something like that, thank you mike, great videos
Hey Everardo, that is the 2767-20. It's a monster. You will love it! I haven't used my air impact since getting my hands on that thing.
Mike Becker, Senior Technical Instructor
Thank you Mike. Good job. Appreciate your work for us all. Look forward to next week's scope results.
Hey Billy, thanks! You won't have to wait a week. It's coming out tonight!
Mike Becker, Senior Technical Services Instructor
Most likely 90% of mechanics do not do this job.
Gotta find that 10%. That's where you want to take your car.
Mike Becker, Senior Instructor
Thank you so much for you series of videos!!
Question - I noticed, in your video, there was more varnish build up under the valve cover of the front bank (4,5,6) than in the back (1,2,3). What would be the reason for this? I just finished doing the valve adjustment on a 2006 Honda Accord 3.0L V6 (the exhost clearance on cylender 4 was at .005 inch) and saw the same thing. The front bank was full of gunk while the back, thankfully, was relatively clean. There was also a ton of buildup (oil and soot) in the two intake manafolds, the intake plenum, and throttle body behind the butterfly valve. Is this some how related to the valves being too thight? Or is it related to something else?
Hi Shawn,
Wow good observation! I didn't even notice this until you pointed it out. My only guess would be the rear l uses a little different oiling set up than the front cylinder head. If you notice in the video, the rear has a aluminum housing on top of the rockers, that is a VCM unit used for cylinder deactivation. This may change the way the oil flows though the engine. A slight difference in temperature, either from oil flow or cooling may also contribute to this, but I can not say for certain.
I'm glad the video helped you out and thanks for the question!
~Ryan
Bought my 07 Odyssey brand new and it has never been to a dealership or garage since! I have changed the timing belt, water pump, plugs and coils, belts and high pressure line to rack. Numerous brake jobs. 160k miles. I’m getting the PO 300 codes now on all cylinders. I reset the codes and it runs fine for a while. Do I need to do this adjustment now?
Yes
hi, tell me please, something that looks like a camshaft is knocking in my head, odyssey 2009
Hook a shop vac up to the inlet port of the upper intake before you pull it off. There could be some carbon crystals or dirt that become dislodged and fall into the ports on removal. Shop vac can prevent that. ;)
Hey Juan, not a bad idea!
Mike Becker, Senior Instructor
Looming for advice, I have a 2006 odyssey that's a crank no start situation. Its. Running normal after a cold start in about 15 to 20° weather w/snow and ice. After about 45min of across twn I was in PARK only about 5 min at idle and the rpms shot up. In drive idle semmed better but accelerating it had no power. Just bog dwn it felt like. Misfiring is the best way I can put it. So I understand the Tps sensor or switch may have failed? And/or the map or egr could effect the situation as well? After restarting the problem went away and before making it home while driving the van lost all rpm and believe it misfired to a stop and engine died. No restart. I noticed my snorkel had broken recently during the cold spell. Cracks in the tubing lead to reasonably wide (splits ) in snorkel. Tomorrow I plan on scanning for codes and going from there. No real regular maint besides oil changes and vsa being serviced. I do have a multi meter and some idears on checking tps and relay continuity and what not. Specs are easy to find. Just the over all direction and approach would be appreciated. I beleive spark and fuselage not the issue here. Im a carpenter as well. Somewhat 🔧Er but no means a mechanic. Thanks and stay warm.
Sure sounds like a vacuum leak or IAC is malfunctioning. Get a cigar and some aquarium air tubing. Disconnect a vacuum hose and attach the tube to the inlet port. Duct tape it if need be. Start puffing and blowing smoke into the tube. Watch for smoke. You should be able to see where the vacuum leaks are coming from without running the engine. I would recommend cleaning or replacing the IAC motor if this doesn't remedy the issue. Since it's really tight around the rear bank, some BRIGHT lights in several spots around the engine bay can make the smoke easier to see. A borescope would make this WAY easier on the odyssey. That thing is jam packed.
You can't hook the tube up through the throttle body because it's drive by wire (electronic controlled throttle plate... not opened by cable). Depressing the accelerator will do nothing while the car is off and you shouldn't move the throttle plate by hand. The ECU needs to be energized to open the throttle plate.
They're not like old throttle bodies that you can just stick a screwdriver into to hold them open, or push down on a side lever. It's all controlled electronically.
You might also suspect problems at the throttle body, and might need to reset it. Cleaning it could be risky if you don't know what you're doing. Electronics could be damaged in the process. To reset the throttle body and synch with the ECU, turn the ignition to RUN for 2 seconds but don't start the engine. Start the engine and run at 3k RPM until the radiator fans engage. Let it idle for 5 minutes with no load (nothing on in the car, no heaters, lights, stereo, etc... everything is off). Then shut off the engine. It should resynch the throttle body with the ECU.
Nice, but there is missing important thing, where is the place to rotate the shaft to get the number? you didn't video this place!!!!
Hey Alnuaeme, thanks for watching. You would spin the crankshaft pulley using a ratchet.
Mike Becker, Senior Instructor
thanks for the great video, i got 1 bolt broken while i was tightening the valve cover, can you suggest how to get the reaming part out of the hole?
Hey Ahmed, drilling and using an extractor is probably the way to go. Good luck!
Mike Becker, Senior Technical Instructor
@@GoTechTraining Thank you very much, i have done the tuning and the check engine light has been gone (after more than a year no mechanic cold identify the problem except one). the car now runs very smooth and no vibrations.
In mid process right now.
2010 Honda odessey with 210k miles.
1. Does it matter what direction you turn the engine over? Clockwise or counter?
2. The peeper hole is very convenient. I have found one on each side however. Does it matter if I reference the front bank peeper hole while adjusting the rear bank cylinder (with correct cylinder number)? My front peeper hole paper shows me cylinder number 3 which is in the rear.
Hey insideHARDWARE,thanks for watching. Yes it matters. That engine should only be spun over clockwise. If I remember correct, I only used the front peep hole on this one.
Mike Becker, Senior Instructor
It does not matter what cylinder you start on, if the first number that comes up is cylinder 3 you can start on cylinder 3. All that matters is that you turn the engine clockwise, and you stop on the mark, and that know where the corresponding cylinder is. It is super easy just very tedious. I'm sure you probably have figured it out by the time I left this comment
i hope you do some episodes on the compression transducer in details with the picoscope and how we get a good reference to compare it with what we have .. thanks great video as usual
I hope to make so more as well! Thanks for watching!
Mike Becker, Senior Technical Instructor
Beautiful explanation....thanks a lot !!!!!!!!!!!
Beautiful job ☆☆☆☆☆
Thanks Denis!

Great video bro. Many thanks
Thanks Doyle!!
Mike Becker, Senior Technical Instructor
Would I be able to get the part number of the valve cover gaskets? I'm having trouble finding them.
Thank you in advance!
FEL-PRO VS 50607 R
I have the same and I want to assure you the same where are you located
Thanks so much for showing how to clear that wire harness off the back cylinder. It's been driving me wild!
I have heard many a Honda V6 owner say my valves are fine and don't need adjusted...listen to how quiet the engine is. Well, the noisy valves are the ones that are OK. It's the quiet valves that are the problem!
You know what funny, service info say to adjust only if noisy...hmmm someone failed on that one! Haha
Mike Becker, Senior Technical Services Instructor
Mike, I think it's the way they write it. Honda says to adjust valves at 105K (Maintenance Minder item #4) and at other intervals A, B, 1, 2, or 3, only if noisy. So, they definitely want them adjusted at 105K but at other service intervals only if there is associated noise. Many think that means only adjust the valves if they're noisy. I've seen many a J35 misfire solved with a valve adjustment and it's always tight exhaust valves. It's pretty safe to run these to 140-150K before a valve adjust but I certainly wouldn't run them longer.
I'm thinking this was the first time these valves were adjusted on this one. Judging by the condition of the valve cover gaskets, I believe I was the first one to remove them at the 210k mark. Have you seen these motors actually get bad enough to burn valves?
Mike Becker, Senior Technical Services Instructor
I don't have enough experience with them to know whether they will or won't burn valves. I haven't seen any burnt valves. In my experience they run bad and set the misfire codes prior to that happening.
Isn't that cylinder 1,2,3?
I wish you were living close to Austin, so I can bring my 06 Ody with 242k miles for valve adj. There is no misfire, but the engine sounds a bit rough. How much this job approximately should cost?
Hey Boris, sorry man! I'd love to take care of it for ya. It's not a cheap job. Hard to say with your local labor rate, but i'd expect to pay more than 500$ and less than $1000 for just the valve adjustment procedure.
Mike Becker, Senior Technical Instructor
Hi, can you use the same old intake gaskets ?
Hi my odissey needs a tuneup and this, I live in mke.
I appreciate your work to produce these videos but the background music could be eliminated. I’d rather hear you talk .
Thanks Wayne, I'll keep that in mind!
Mike Becker, Senior Technical Instructor
So do you have to be on tdc compression when turning the engine? How do you know if youre on tdc compression?
When both the exhaust and the intake rockers can move. That indicates your on compression stroke because all the valves on that cylinder are all closed. I think on the crank pulley there are other marks you can look at as well. Watch a few more videos and you will see.
Appreciate the info
Thanks for watching FrankO!
Mike Becker, Senior Instructor
Thank you Mike I Appreciate you Time and Work
Hey David, thanks for watching!
Mike Becker, Senior Technical Services Instructor
So if you have a random misfired, the valves need to be adjusted ? Just on odyssey or all Honda models ? Was there any code for misfiring ? What diagnostic procedures that pin pointed to the valves issue?
Hey Mckoy Lach, seeing as how you watched the video "part 2" and left this comment, I assume you didn't see part one? Part one is where I did all the diag. I'd suggest taking a look, you may find it interesting :)
Mike Becker, Senior Instructor
GoTech thanks
Ask Milwaukee to send Thomas at exodus some tools. He has a great vw audi channel.
Hey Richard, Thomas does have some great stuff!
Mike Becker, Senior Technical Services Instructor
The tools would get a good workout, those VW and Audis break down a lot and keep their mechanics busy lol.
Sounds silly but great to see how I'm able to swap out the gasket...had a slow drip that was hitting a sensor causing some smoke...seems like a reasonably easy task to replace just the gasket...much thanks!
Hey TTV BTW, glad this vid was able to help!
Mike Becker, Senior Technical Instructor
These engine you really want feeler gauge that is bent on the end. When ur adjusting them you want a slight drag on the gauge no more than that. Also that back bank is gonna be a pain. Especially cylinder 3. Another thing don't forget to put Honda bond on the valve cover, on the sides where two pieces on metal come together.
All great tips! I bent my feeler gauge for the back 3. You're right, they were a pain! Anytime I do cover gaskets on anything I put some sort of silicon RTV where metal surfaces meet.
Mike Becker, Senior Technical Instructor
Great presentation! If your diagnostics showed the intake valve function OK, can you save the customer money by just measuring the intake valve clearance and not adjusting it if it is in spec?
J Eadie, thanks! Sure! No sense in adjusting the intake valves if they are in spec :) Most places probably just charge one flat labor for a "valve adjustment".
Mike Becker, Senior Technical Instructor
Excellent details and explanation.
Hey Gregg, thanks for watching!
Mike Becker, Senior Instructor
2007 odessay had mecanic replace rear head after replacement engine valves clacking , mechanic said drive it put miles on it , so i put about thousand mi. on it then took it back for readjustment of valves so drove it and still have some clacking. so is that normal for honda engine? ( before it didnt seem to clack that much ) also engine light came on and flashing , parts store said multipile coils or spark plugs so how can multiple coils go out. same time ? or plugs or does it have something to do with valve adjustment? about hundred thousand miles on motor. anybody out there can give me some input if you had same problem or somebody with honda engine know how? thanks if you can!☺
Hey, I don't really see why it would be noisy. These engines aren't really known for that. Flashing check engine light usually means you have a dead cylinder. Severe misfire. My guess is everything here is related. Hard to know for sure...but that's what my gut says!

NGK Technical Training. thanks for response ! gonna take it to different mecanic . can valve lash be checked by compression? i would think not have to guage it right? THANKS!
Clogged egr path and filthy throttle body can cause miss firing, interesting how narrow it down with scope.
Hey Dave, sure, they both can cause misfires. Clogged EGR will usually only affect 1 or 2 cylinders consistently. Whereas this problem was random and affecting all cylinders.
Mike Becker, Senior Technical Instructor
correct my terminology if I am incorrect with the words but How are you spinning the motor?
Hey Levi, I used a breaker bar on the crankshaft pulley bolt. Make sure to always spin the engine in the same direction it normally rotates, or in this case, clockwise.

I've always just guessed my lug nuts lol 😆
FYI lmao I think I messed up my engine on readjusting the values I did everything but when I’m useing the feeler gauge either the .008 or the .012 I’m a novice when it comes to feel for it it’s the right amount of resistance when I sliding the gauges back and forth I’m thinking about restarting the process any tips on this subject matter???
Levi, the process is pretty straight forward. Make sure when you slide that feeler gauge in there that you have just the slightest drag. Not tight that it's hard to move and not loose that it can bounce around on the feeler gauge.
Mike Becker, Senior Technical Instructor
Make sure your on the right cylinders number
I just pushed the rear harness up and back, and slipped the valve cover out. Same in reverse. Did have my son hold the harness up while I replaced the valve cover, which made it easier. I never removed the power steering pump at all. Mine is an 04 though, so maybe different? Bad thing is, I still have my miss, after all this.
Ohhh sorry to hear you still have misfires!!! That's very unfortunate after all of that work.
Mike Becker, Senior Technical Instructor
@@GoTechTraining Not noticing the miss so much now. Wondering if the continued miss was just temporary, due to some oil that got into the cylinders, which is another story... Still got the flat spot though. It only manifests on the first acceleration after starting it, after it's already warmed up.
I was able to remove the rear valve cover by opening the complete wiring harness cover,(plastic) and gently pull the harness out of it and then unbolt the holder. Easily removed the valve cover then. Your video is absolutely the best. The numbers on the window are really a pain because they are upside down on my 06 Ridgeline. Also all numbers are present on front window. I tried to use the rear cam window, no numbers on the rear cam. Take your time, yes a weekend, but this is doable. Would love the torque specs though. Thank you for teaching us DIY folks.
for the back head, why didn't you take the cowl off
If only it was that easy. I looked into it. The cowl is just a cover over a part of the firewall. It's all welded together. Taking the cowl off would have only reveled the metal sitting below it :(

Wells Vehicle Electronics it was just a thought
Always go with the larger spec no matter what. These intake valves usually don't need to adjusted much.
You've done a bunch of there? Bigger size makes sense considering how these tighten and not loosen.
Mike Becker, Senior Technical Instructor
How much should that cost at a honest shop
What is the torque spec for those lock nuts we need to loosen and tighten? Thanks!
Hey, i'm seeing 14ft.lbs on those nuts.

Also the vehicle keeps going into the protection mode where it shuts down three of the six cylinders very annoying is there any way of disabling that I did notice a lot of smoke comes out the exhaust at times Blue Smoke
I don't believe there's a way to disable this system without some form of tuner system.

find a video of replacing the the vtec spool valve gaskets. you can buy a whole new assembly for 350 or spend less than 50 on a solenoid,gaskets, and a oil pressure sensor switch. your gaskets are leaking and the screen is plugged up in the gasket. this keeps the vcm from working properly and causes the codes and smoke and bad running engine.
how did you turn the crank pulley? what is the nut size?
Hey Ahmed, usually it's a 19mm or 21mm.
Mike Becker, Senior Technical Instructor
Wait is that the same engine that Eric O's working on with the DIY head gasket replacement? 😊
Similar, I think his is the older generation 3.5. The intake looked different.

Can valves needing adjustment cause smoking? My 08 Odyssey I just got smokes a little during light throttle not on start up. I'm thinking valve seals. But could valves being out of adjustment cause smoke? I just did the timing belt thinking the ticking I heard was the tensioner but it's definitely a valve being lose tapping. I'ma adjust the valves soon after I do another oil change to clean the engine out.
I did my 02 Accord V6 in less than 2 hours my first attempt with an electric ratchet.
Front bank of cylinders were way more cooked looking. Wonder if oil isn't circulating as well up there and is getting baked?
Hey Mrdumbfellow, thanks for watching! I was also surprised at the color difference front to back...has to be a for a reason.
Mike Becker, Senior Instructor
@@GoTechTraining Probably has to do with the VCM system, shutting down Cyl 4 and 6 I believe....there is a way to disable it though.
It's normal on these engines, even the ones without VCM. I'd suspect it's from crankcase pressure building up in the front valve cover. That's where the PCV valve is located. Also could be a new head in the rear bank. Some mechanics seem to think that the rear bank head on the J series has camshaft design flaws (like Scotty Kilmer). I don't believe that nonsense myself... but the rumors exist. I've seen a few with spalled cam lobes on the rear bank, but it's not necessarily a design flaw, and that's not what Scotty mentioned specifically.
This is how my old Suzuki motorcycles valves were adjusted and you had to check them often. Thanks

Nice video i have a ody 01 and has 200k now and I’m planing to this myself i feel confident i’ve doing all my repairs on my car for a while but i never try this before i’ll clean the egr passages at the same time and replace the fuel pressure regulator i wanna adjustment the valves cause on cold I’ve noticed this year it starting to make noise
Hey Fredy, thanks! I'm glad this video has given you the confidence to do this job yourself! Thanks for watching!

Wells Vehicle Electronics i’m almost ready to the valves on my honda i just waiting for the gaskets and got the feeler gauges already intake .0009 should be fine and exh .0012 that would be ok right since its 008 - 0009 intake and exh 0011 - 0013 do i need to use hondabond I bought it as well also got the new intake manifold plenum gasket
interesting viewing there mike...looking forward to the scope results
Thanks Shaun, glad you found this case study interesting!

Saldudos desde mexico a cuanto torque se ayustan los balancines tengo el motor 3.5 de un honda accord coupe 2011 no encuentro el dato de a cuanto se torquean. baje la cabeza para cambiar valvuilas de el cilindro 3 pero ya me atore en apretar los balancines a la cabeza. Espero me puiedan ayudar¡¡¡¡
It helps to have the right tools. This guy is kinda winging it.
Every job is eaiser with the proper special tools! Sometimes people don't have them. Like I did not, so I "winged it." Either way the job was finished and the customer was happy. Some new bent feeler gauges are on my shopping list though!
Mike Becker, Senior Technical Instructor
skrub love Very few cars still have adjustable valve mechanisms. He might not adjust Honda valves everyday, he doesn’t have the Bluepoint tool, but he can read and follow directions superbly. And that is what is of value to me. Now when he gets out the electronic stuff, all bets r off. That is his area of expertise. This video was extremely helpful as I am doing one today. Thank u Mike!! No disrespect Mr. skrub.
Yeah I love my Milwaukee tools as well they are great. Another great video keep these coming
I have used many brands, battery and air...my Milwaukee stuff is the best by far. My air compressor rarely gets used anymore....If only Milwaukee made an air hammer like "Big Nasty"
Mike Becker, Senior Technical Services Instructor
Dang they have taken up almost half the space they are alloted. You'd think honda would have also put a stopper of sorts to prevent it from closing but they didn't
Honestly. How much is this repair. Same vehicle?
Gabe, depends on the shop...probably at least 500$
Mike Becker, Senior Instructor
@@GoTechTraining thanks! that seems kind of cheap considering what all you have to do . Even though that's a lot of money. Lol. Cars are complicated and they're all different. Thanks again ! And for sharing. 😁
The long feeler gauges with a bend work well for this, too.
I should have bought one just for this job. Probably would have saved a good amount of time on this one...next time :)
Mike Becker, Senior Technical Services Instructor
Yeah, I bought my long set when I was getting ready to do my first J35 valve adjust. Always got by with the short set all these years. And if you think your chest hurt after the Ody, try the Pilot. The Pilot is far worse because the engine is so far down below the radiator support. A top side creeper is almost a requirement.
I'll keep that in mind! Mental note to turn away Pilots, got it :)
