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.!!!

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 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.

@flbartlett 5 лет назад

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.

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".

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.

@GoTechTraining 6 лет назад

I'll keep that in mind! Mental note to turn away Pilots, got it :) Mike Becker, Senior Technical Services Instructor

@bernhardlist9359 6 лет назад

The symptoms you mentioned: increasing RPM makes the problem worse plus a 14% short term fuel correction looks more like a slow MAF sensor (at such a milage this is not unheard of). Also a random misfire could be a result of this. Recently I got a car with a timing chain tightened in the wrong sequence and the cams where both over 16 degrees of and still had only occasional, but I admit, random misfire. This could be seen very prominent in the Picoscan. I am eager to see if this fixed it. Bernhard

@haywardsautomotive6156 6 лет назад

He said It is noticeable & worse at idle and is better cold but gets worse as it warms up which screams exhaust valve adjustment

@bernhardlist9359 6 лет назад

Hayward's Automotive Ok thanks for the info. Disregard my comment but looking at the pressure scan there is no obvious valve problem. 30 to 50 degree is a rough guess to get started but what is the Honda manual saying? For final diagnostics you have to use the correct values and test them at operating temperature. Greetings

@GoTechTraining 6 лет назад

Hey Bernhard List, I see this video series really has you thinking. I love that. I love this sharing of knowledge and opinions! I can say without ANY doubt that the timing was dead set on this engine. I did a timing belt replacement after I adjusted the valves and the cams and crank were in perfect position. No noticeable belt stretch either. The belt was 90k miles old. I agree, the correct values are ideal...but we can't always get those. It's not always that easy to just find an exact spec. If it were we wouldn't have "rules of thumb" right? Mike Becker, Senior Technical Services Instructor

@johnaclark1 6 лет назад

I would agree on the MAF suspicion but a MAF issue should affect both banks equally. The other thing than that can happen on these vehicles is skewed O2 sensors. When all else fails and you have high fuel trims 10-20% total and no code or explanation I have solved it by replacing all four O2's. This is usually on vehicles with over 150K. I found this on my own 08 Odyssey but a couple of other similar vehicles belonging to customers of mine. Checked everything and could find nothing wrong, even with the O2's. Finally replaced the upstream A/F sensors (even though I could find nothing wrong on a scan tool with them) and it brought trims down about 5%. Drove it a few weeks and nothing changed. I then replaced the downstreams and the fuel trims dropped to nearly 0%. Many people don't realize it but on AF sensor vehicles often the downstream O2's are used for fuel control and even though they appeared to work as they should, they were skewed after 170K miles. Engine now runs as good at 180K as the day I drove it off the lot with 6 miles.

@usnchief1339 Год назад

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!

@INSIDEHARDWARE 4 года назад

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.

@GoTechTraining 4 года назад

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

@youandiryan 3 года назад

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

@toddsorenson9470 4 года назад

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?

@mapweb2000 2 года назад

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.

@whozaskin3639 6 лет назад

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.

@prevost8686 4 года назад

I just did a 2005 Odyssey today with multiple cylinder misfire codes. I simply couldn’t convince my shop owner, who was never a technician, that tight valves could cause this issue. He sold the customer 6 new coils and plugs. It was only when I said that if the codes came back i wouldn’t be responsible that he finally called the customer again and sold a valve adjustment. All 12 exhaust valves were around 4 thousandths or less. 153K miles. Strange to me how the K24 engines never exhibit this issue.

@GoTechTraining 6 лет назад

Hey Mike, I wonder why? Any idea? Mike Becker, Senior Technical Services Instructor

@joneskey3950 6 лет назад

The only explanation I can think of is the front bank cylinder head has the built in EGR ports and runs much hotter, the rear cylinder head does not and stays much cooler. More often than not I have also noticed the front bank (Bank 2) valve clearance a bit tighter which could also be related to exposure of exhaust heat via EGR ports. If you look at their newer generation engines they have stared using an external EGR pipe and no longer use the internal cylinder head routing.

In the service manual, they show the use of an air adapter for ‘unlocking’ the cam lifter/followers. The setup of the valve clearances seems to be different when using that method.

OK. This is just cool seeing the inside of my engine. I do have a question for you. I took my 07 Ridgeline 3.5 I believe the same engine as this is back to the dealer with a concern. I told them when I'm cruising along at 50 60 and give a little gas it seems to hesitate but if I push more it takes off. I was told by a mechanic to run 4 o5 tanks of high test and the cleaning agents will do the trick. I did so and worked like a charm but now I'm back to regular and the hesitation has returned. What does this mean? Bad coil. Bad plug. Bad/dirty injectors? PS. I put high test in again and runs like its new. I have 140,000 miles

Wells Vehicle Electronics Hi Mike, I've always ran regular 87 octane and it ran perfectly until now. I get the hesitation like I spoke about. I put hight octane in I think its 92 or 93 octane and all runs smooth. We do have the ( No ethanol ) option here so does that make a difference? I have ran both.

@GoTechTraining 6 лет назад

Craig, something has changed. You vehicle is intended to run smoothly on 87. You should not have to run high octane fuel.

Crazy There was a reason they did away with tolerance checks back in the early 1970's People didn't like doing them and the earlier engines were far easier to get the valve covers off Well I guess those cars exist for those people that just love to waste all day under the hood of a car.

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

In ECO mode, there is still misfire on all cylinders. In permanent error mode the problem does not occur. Will you help??

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!

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🙏💯

@GoTechTraining 2 года назад

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 Год назад

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

@lloydballard7051 Месяц назад

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.

@johnaclark1 6 лет назад

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!

@GoTechTraining 6 лет назад

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

@johnaclark1 6 лет назад

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.

@GoTechTraining 6 лет назад

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

@johnaclark1 6 лет назад

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.

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?

@GoTechTraining Год назад

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

@elgaaens Год назад

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?

@GoTechTraining Год назад

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

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.

@Npc5150 3 года назад

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.
