2006 Honda Odyssey 3.5 Random Misfire Case Study Part 2 : How To Perform A Valve Adjustment

[@tshinefield]

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.!!!

[@funtoyreviews4127]

i watched so many videos no one ever showed the adjustment like you did im thankful for people like you ! you save me so much money so i thank you my friend and godbless you and may you have prosperity in everything you do .

[@rickcarlyle4914]

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.

[@wyattoneable]

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.

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!

[@GoTechTraining]

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 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

[@mcroadracer1]

This is how my old Suzuki motorcycles valves were adjusted and you had to check them often. Thanks

[@Lloyd-z3q]

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.

[@flbartlett]

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.

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??

[@Lloyd-z3q]

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.

[@crystalstanford1840]

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".

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?

[@wes365]

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]

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

Hey Edwin, things just keep getting packed tighter and tighter. It only gets worse with turbo motors and such. Oh well, more labor time for us I guess! Mike Becker, Senior Technical Services Instructor

[@johnaclark1]

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]

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]

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]

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]

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.

[@elgaaens]

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]

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

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.

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

[@toddsorenson9470]

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]

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.

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

[@youandiryan]

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.

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]

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.

[@georgegonzalez2442]

Good job! A few notes from my own experience with a J32, a very similar engine. If it's a Florida car or has been in sandy areas there may be large amounts of sand and grit on top of the engine in nooks and crannies in and around and under the intake manifold. Blow or wash that stuff away before you open up the engine. Take your time. Double check the clearances. Be sure to tighten the adjuster nuts! Every one of them. Check them twice, at least. Otherwise a nut will loosen and you'll hear a click click noise starting up within a few days and you have to take everything off again. Do use a long bent feeler gauge. If you don't you may be fooled into thinking the gauge is dragging when actually it's just bent and wedged, many thousandths wider than optimum. A couple of bungee cords will help to hold the wiring harnesses out of the way. See those 12mm drain holes in the head? A lot of stuff could fall down through them. Consider maybe plugging them while working. Golf-tees are too small, hot dogs too large, find something in between. Take a long break and recheck the clearances. You have 48 chances to screw up a clearance or nut tightness. Get them all right the first time.

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.

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.

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

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]

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]

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.

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

[@GoTechTraining]

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

[@johnaclark1]

The long feeler gauges with a bend work well for this, too.

[@GoTechTraining]

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

[@johnaclark1]

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]

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

[@SinMideo18]

So do you have to be on tdc compression when turning the engine? How do you know if youre on tdc compression?

[@edclayton99]

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.

[@AppleTechPro870]

Do we need to rewind the camshaft to cylinder 1 mark, or leave it at what ever cylinder it was done last? Do we have to rotate the camshaft cylinder or not? Thats what i want to know. Or that doesn’t matter?

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???

[@GoTechTraining]

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

How often, and at what mileage, does Honda recommend that this valve adjustment be done?

[@poke_hoard422]

Ik 105k miles but unsure after that. I'm close to 300k so assume it's time

[@poke_hoard422]

It actually does say in your manual also

[@DrJeff-vn1st]

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. I just setup a rebuilt head that way, misfires and the engine manifold vacuum is only 11psi. Does anyone else have feedback on the manual? Did I mistake the instructions?

[@Usgiarmy]

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

[@jeremyanthony9300]

for the back head, why didn't you take the cowl off

Wells Vehicle Electronics it was just a thought

[@KenMisiak]

So I'm working on adjusting my valves in my 06 Honda Ody. First time I've done it. I've got the valve covers off and cleaned up. I have new seals for everything. I'm wondering where the Hondabond/ high temp RTV goes? I did not see any RTV type material anywhere when I pulled off the covers. Do you coat the new gaskets with anything? Do you put hondabond or light coat of oil on the gaskets? Thanks! Also, I managed to remove the wire harness by the power steering pump without removing the pump itself- I just unclipped the rectangular plastic housing and wiggled the wires between the power steering pump and intake. Super helpful video! Thanks.

[@GoTechTraining]

Hey Ken, congrats on tackling this job yourself! The RTV goes on the back valve cover where the sharp upward corners are. This helps to ensure a proper seal. As for the gasket itself, that goes on dry and clean. Glad the jobs going well for you! Mike Becker, Senior Technical Instructor

[@KenMisiak]

Thanks Mike! Those back exhaust valves are hard to get to! After all day trying to feel the difference for .001" you begin to double guess yourself! I had it almost all back together when one of the valve cover bolts sheared (I didn't torque it hardly at all). So now waiting on a bolt on order. Surprising how far out some of the valves were. I don't think it was ever done before, but I did fine some intake valves that actually had way too big of a gap too.

[@GoTechTraining]

Those back ones are fun aren't they!? Sorry to hear one sheared off, that's no good. Puts a damper on trying to get the vehicle back up and running. Interesting your intake valves were out of spec too. Mine were all ok on this one. Curious to hear back from you on how it runs now! Mike Becker, Senior Technical Instructor

[@jeadie8131]

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?

[@GoTechTraining]

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

I have a question because I’m confused on the intake says .008 and .009 what and on the exhaust.0011 .0013 what number should I use on the intake and the exhaust

[@GoTechTraining]

Hey Hany, those numbers are a range. .008 to .009 for intake and .011 to .013 for the exhaust. On this engine, the exhaust valves tighten over time so I prefer to adjust them to the .013 in order to get more time out of them. Mike Becker, Senior Technical Instructor

( 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!☺

[@GoTechTraining]

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.

[@atm9566]

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.

[@GoTechTraining]

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

I cant believe Honda still uses the mechanical valve adjustment. wonder why they didn't do hydraulic lifters

[@GoTechTraining]

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

[@whozaskin3639]

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.

[@WavveBoi]

Is this the same or similar to the j35y in my 13 Accord?

[@GoTechTraining]

[@davemc3650]

Clogged egr path and filthy throttle body can cause miss firing, interesting how narrow it down with scope.
