[@planegaper]

Thnx for going so in depth on your video's .. here's my story.. had the same problem with my 04, has 200,00km on it.. took it to a mechanic and he tried to sell me on a timing belt/water pump before even opening the hood.. I'm ok with tools, and know my way around an engine.. besides this mechanic was a parts buyer n trier, no diagnosis.. except he started at expensive and went to simple ..before shelling out 1000 bucks to find the belt didn't skip, i decided to watch a few video's on the subject.. 1. did a valve job my self, no probs 2. egr cleanout and valve check , all good 3. belt can be checked on an Odessey ..all good!!! it had been done recently tension was perfect!!! top and bottom.. 4. plenum , iac , vacuum leaks, cleaned and checked, 5. plugs replaced.. injectors cleaned, plenum gaskets cleaned, pvc valve checked, sensors checked 5. Finally i diagnosed the coils one by one, found 3 and 5 were bad.. replaced em, and it;s all good now The same mechanic called me two weeks down the road, and threw me a 1000 bucks offer on the van, it needing a timing belt and all !!! , i told him i reshaped the belt into coils and it runs great now.. but now I see the logic , an 04 :Oddessy with low mileage for it's age is a good profit margin for a re sell.. easy 1000 bones, more since he doesn't have to touch the belt ..pilot Odessy are popular and sell fast.. Your video's gave me bullshit armour, and I was able to defend my self from a con artist and saved me tons of cash!!! And i know everything I checked is good , and i'm far more familiar with my drive train.. thanx guys, keep posting em, content is in depth, and logical, and did a valve job 600 bucks for free!!! and yes some exhaust side were too tight, draggin hard on 13 thou, finally learned how to diagnose a coil w multi meter, and 100 bucks in parts later is was good to go.. plus the engine has had a thorough cleaning and going through..maint i won't have to pay for down the road.. hopefully i get another 30,000 care free miles out of her.. iol and coolant change before winter and i'm good to go !!

[@lesliedsouza4077]

Excellent presentation, as usual :) ONE factor was left out: Compression! 58 psi before - 114 psi after! My 1988 Suzuki, 1000cc, carby engine does 120 psi on 4 cyls @ 200,000 km (125,000 miles). Other car, 2003 Camry was 200 psi +/- on 4 cyls @ 125,000 km, last yr. Now 165,000 km, pending P0135 code. Thanks to your videos, I know what that means. HOS2 1 being replaced tomorrow - Not waiting for MIL :)

[@GoTechTraining]

Hey Leslie, thanks for watching! Mike Becker, Senior Technical Services Instructor

[@ronmelliad7327]

I did the valve adjustments and T.belt replacement along with three coils on a 2004 Pilot with about 260K miles and as you pointed out and they were snug. The check engine came back on on the way to deliver the car; the same multiple misfires. The owner didn't want me to spent more time because overall, it was riding OK. Now, after 13K miles they need to get an emission and wanted me to fix the MIL too. Misfires can have a several causes. It should be called more as engine "miss" than "misfire". It's multiple and random; some cylinders stay the same and some come and go! I have a generic scanner. I lean more towards that the injectors quit in a fraction of a second. My second and third guess is the EGR or even the PCM. I am afraid to go and put parts in there because this car doesn't have much value anyway.

[@khuranashyam]

Good amount of details, step by step explanation; great attitude, I wish my mechanic was like you. Keep continuing.

[@GoTechTraining]

Thanks so much Shyam! ~Mike

[@bamfski]

Thanks so much for making this series. I had a constant cylinder 6 misfire. Eliminated coil and injector as the possible cause. Adjusted the exhaust valves and the engine is running smoothly.

[@bmclaren99]

This was a great series. Like the multi-day format. Lets you think about the problem a bit, and gets the answers shortly after.

As an Odyssey owner myself, I loved this series. There's not a lot of Honda video diags out there so this fills a niche. I have a Vantage Pro I picked up used on eBay w/16.4 software but sure wish I could justify that Pico or at least that fancy pressure transducer.

[@GoTechTraining]

Glad I could help fill the niche with these videos. The pressure transducer is handy. It's a great tool! Worth it if you are consistently diagnosing a ton of complex issues. Mike Becker, Senior Technical Services Instructor

[@yetthejet]

My 2008 Odyssey Touring has P0300, P0304, P0306 codes. I fired the parts cannon with new spark-plugs and coils. I drive my van around and after a little bit of driving my check engine lights starts flashing which is a really bad sign. This Misfire series has given me another way to look at the issue. I will adjust my valves. Thank you.

[@yetthejet]

⁠@@kayjay4060I ended up replacing the piston rings myself. This was in March. I also replaced the cats, O2s, timing belt, and other miscellaneous parts associated with a piston ring replacement job. My van has been running like a champ.

[@yetthejet]

@@kayjay4060 That's a good tip. I purchased my van used and had no clue about the VCM until much later down the road. I put on the muzzle before I did all my DIY work. But the rings were beyond a muzzler correcting it. However, since my rebuild, the muzzler has been doing its job. I got so much help from the Honda Odyssey online forum. A lot of good people making insightful comments.

[@wyattoneable]

Thanks for the series Mike. It was interesting to see how much the wave forms changed with small adjustments to the valves. Pretty cool.

Hey Wyatt, thanks for watching! I was impressed by the change too for such a small "tweak" Mike Becker, Senior Technical Services Instructor

[@tommcguire6134]

Outstanding video series. Really learned a lot. You are one of the most clear and easy to comprehend instructors I have seen on KZbin. Keep them coming - great work! I have a 2001 Acura MDX with high mileage and similar symptoms - random misfire. Would think it could be the values but also combined with a slow coolant loss that I cannot find. Have put dye in coolant and also done a combustion leak test on the radiator with a negative result. Not sure if these two thinks are related or two independent problems. Any ideas where I should look for this coolant leak? Does not appear to becoming from the bottom of timing cover but I am not sure if it needs to be removed to check or not. Any advice would be appreciated. Thanks!

[@GoTechTraining]

Hey Tom, thanks a lot man! Do you notice any smoke on cold start up, like after sitting for 2 or 3 days? My guess is the headgasket is starting to go bad...it leaks down when the vehicle is cold. Once hot, the metal expands and seals the leak up...that's my guess. Mike Becker, Senior Technical Instructor

[@tommcguire6134]

@@GoTechTraining HI Mike, there is some white smoke on cold start which goes away quickly. How can I test , confirm a head gasket where it is maybe intermittent due to heat up? Have not pulled plugs yet - would they show evidence? Thanks

[@tommcguire6134]

Also is it likely I would be getting a misfire code on both banks? Both head gaskets going bad?

[@tommcguire6134]

I have P300 code and individual misfire codes from both banks.

[@duanedonaldson2262]

It would have been nice to get the math for actual valve adjustment vs in cylinder valve movement in degrees and how important a small valve adjustment can be. Thanks so much for yet another awesome series.

[@lesliedsouza4077]

Thanks for your replies, Mike. A possibility is, that the heater element was failing, throwing P0135, but not frequently enough to MIL. At sensor replacement, the old one may've been discarded roughly - enough to complete the heater element failure? There was no carbon or wet oil on it - Just dry, white stuff. Whatever - that one can be put to bed. Next, I wondered what the white stuff on old sensors is. Is it ash? From zinc & phosphorous? From a bit of oil burn?

[@GoTechTraining]

That ash is pretty normal. It mostly just happens from the combustion event. Hard to say exactly what it is, besides saying that it's from the exhaust. I think you're probably on the right track with a little bit of oil burning. But again, this is a normal condition on an old sensor. Mike Becker, Senior Technical Instructor

[@jakeandrus690]

Very cool to see that. The instructors at Honda have us only look at MAP voltage for this issue, your way is way more conclusive.

[@Mel-pn1ys]

Hi Mike, very informative video. I have the exact same symptoms as your test vehicle only its a4x4 pilot 2008. Everything was running spot on prior to my two week vacation and upon my return, the battery was dead. After charging battery and starting vehicle, the exact symptoms as described in your video? I have diagnosed that it is not the speak plugs or coils and don't want to waste money throwing parts at it. How could the valves go out of adjustment because of a dead battery?? Do these vehicles have a timing learn adjustment on them so it would have electronically compensated for the valves going out of adjustment, and then when battery died the cpu reset to factory defaults? Any thoughts? Vehicle has 360,000 kms. Thanks for any feedback.

[@GoTechTraining]

Hey Craig B, thanks for watching! The valves are a mechanical adjustment. There is no way a battery issue could cause a valve issue. It's possible that the computer wasn't running the test due to other parameters and then the battery reset everything and the computer ran and failed the test. Either way, the problem was probably always there...the computer just wasn't reporting it. Mike Becker, Senior Technical Instructor

[@mikewithers299]

That's strange. My 2003 Pilot had a similar thing happen last week. Ran perfectly until alternator died and killed the battery. Now all I get are misfire codes. I did adjust some loose valves to spec, and replaced leaky valve cover gaskets. EGR ports and galleys were caked with crud. Those all got cleaned. EGR valve cleaned, new NGK plugs and NGK coils. New PCV valve too. Very difficult to check those valves, but I triple checked each. 22mm intake, 30mm on exhaust.

[@Diagnosedan]

Hey Hoopty_Medic, thanks! Glad you've enjoyed the series! Mike Becker, Senior Technical Services Instructor

[@glasser2819]

how does the exhaust valves exhausting the cylinders a few degrees earlier cause ignition misfires?? I know it does but I don't get the connection between valve lash and lean misfires??

[@GoTechTraining]

Hey, so the valve opening early is only half the issue. The valve opens when there's still pressure before the event is complete. Remember though, since our clearance is lower the valve will actually stay open longer too. This allows more exhaust gases to be pulled back in when the intake valve is open. Inert gas entering back into the cylinder causes it to misfire. Mike Becker, Senior Technical Instructor

[@marccole8345]

Have you investigated VCM issue on 3.5 Honda V6s? Apparently VCM is causing premature cylinder ware, fouled spark plugs and motor vibrations when activated.

[@GoTechTraining]

Marc, some years of the 3.5L had VCM issues where the piston rings ended up having to be replaced. I don't believe that was this model year. Mike Becker, Senior Technical Instructor

[@09hoseclamp]

I was about to change valve cover gaskets and tube seals this weekend, but looks like now I will now possibly be doing a valve adjustment. Thanks alot!! 🤣

[@GoTechTraining]

Hahah you're welcome, I think ;) Mike Becker, Senior Technical Instructor

[@derekmartel7355]

Great video! I have been starting to learn more about In-Cylinder PSI Testing. I am getting mare familiar with this test. Can you recommend where to find some "knon-good" patterns for vehicles? Thanks.

[@ronmelliad7327]

I suggest to replace the spark plug tube seals if the coils are oil soaked. That's the number one reason for misfire. Putting back the valve covers are a little tricky on these cars; have to make sure the seals go all the way around the tubes otherwise they will be tucked in and get ripped and leak.

[@Andromeda1st]

You said on your video that you did something with the timing belt and water pump? Did you change because of maintenance? After doing the valve adjustment on this Homda Odyssey

[@GoTechTraining]

Hey Oscar, yes the vehicle had a water pump and timing belt replaced as maintenance. Mike Becker, Senior Instructor

[@georgegonzalez2442]

Great series, Mike. Just one thing, at one point you seemed to suggest that the intake valves you might want to adjust like the exhaust ones-- a little bit towards the loose end as they will continue to tighten up. That's probably true for the exhaust valves, yes. But the intake ones seem to hold steady over time, perhaps the seat is dropping just as much as the cam lobes and rocker arm tips are wearing down. So maybe adjust the intake valves right down the middle?

[@GoTechTraining]

Thanks George, i'm glad you've enjoyed this series. These intake valves were right in spec. I believe I was the first person to pull the covers on this motor. 210k and the intake still in spec...yeh I'm not touching them. No reason to. Spec is spec. .008 to .009 does't leave a lot of "adjustment' room on the intake side. Mike Becker, Senior Technical Services Instructor

[@petemiller5813]

Great video and follow up. Question: your thoughts on using a .0005 increment indicator placed on the cam side of the lifter arm to set the valve adjustment. Select the desired cylinder using the supplied pointer. Run the adjuster down to zero lift arm movement, set the indictor at zero and loosen up the adjuster until the indicator shows the required clearance and lock it down.

[@GoTechTraining]

Hey Pete, thanks man! I'm having a hard time visualizing your procedure here, but is that easier than the way I did it? I feel like it is pretty easy the way I did it. The hardest part is getting the feeler gauge where it needs to go. Mike Becker, Senior Technical Services Instructor

[@davesage9190]

Hi Mike:I think what he's saying is - use a dial indicator on the rocker arm. I think it's a good idea. The magnetic base can be mounted on the engine, the indicator brought over to the rocker. You adjust for zero lash, zero the dial indicator and then adjust the lash while moving the rocker up and down and watch the dial. I find with a feeler gauge - like you say - it's hard to get it in and there's always that question if the friction is correct or becasue you have the feeler cocked on an angle. With the dial indicator you have to be sure to put the indicator tip on the end of the rocker over the valve not over the cam end because there may be a rocker ratio going on. So indicatiing over the cam would be off by the rocker ratio. It might be tough to get an indicator in place on some engines though. It looked pretty tight on the Honda you were doing. But from my experience (on model engines) it works really well. Also good for valve timing checks when you combine it with a leak down setup . i.e. listen for the valve to open and observe the lash on the dial indicator. See my website at davesage.ca Good video Mike. I like to see how the BIG stuff is done. Keep them coming.

[@GoTechTraining]

Hey Dave, thanks for making that clear for me. My brain wasn't putting it together. Sure, that sounds like a great way to do it. I may just give that a try next time and see how it works out! Thanks! Mike Becker, Senior Technical Services Instructor

[@richardcranium5839]

Thanks Richard! A valve is a valve right? Mike Becker, Senior Technical Services Instructor

[@richardcranium5839]

well yes and no. the basics remain the same, while adjustment procedures vary. i.e. some have screws with lock nuts some just adjusters some you shim here or there some have no adjustment but still must be checked due to seat and face wear.(the geometry needs to remain correct) i would advise any one with any question to watch and learn. the day ya stop learning is the day ya wake up with worms lol

[@GoTechTraining]

Hey Oly Wurld, sure it's possible that misfires can cause a rich code...it's also possible that a rich code can also set misfires. I'd suggest inspecting fuel trims for starters. Mike Becker, Senior Technical Instructor

[@olywurldmusic4291]

@@GoTechTraining Could the EGR Valve cause these error codes?

[@GoTechTraining]

Hey, it's possible. Generally speaking, you will only see a few cylinders. These engines like to plug up the EGR passages and then overfeed the open cylinders causing just a miss on those cylinders. Mike Becker, Senior Technical Instructor

[@ghaemie]

Thank you for a very informative video. I have 2003 Acura with 191000 miles. The engine seems like running smooth but it is burning a lot of oil and the Engine Check light is on. As long as I am driving it is ok but when I stop the smock enters inside the car thru the vents. The Dealer diagnosed the problem and claims that they are getting Code P0300 and also engine has random misfire. They recommend Valve Adjustment with Sparkplugs. I pulled the PCV Valve out and noticed that when I shake it, it won't make any sound. Does this means that the PCV Valve is bad? Does burning oil has to do with the bad PCV Valve. I understand that the exhaust valves need adjustment on these cars but is this gonna stop oil burning. I will appreciate your comments.

[@GoTechTraining]

Hey Mir, thanks for watching! Sure, oil burning can happen with a bad PCV valve. The valve could be restricted causing the crankcase to build too much pressure. That pressure can then force oil past the rings and into the cylinder. I don't think a valve adjustment is going to fix your oil issue. It may fix a misfire, but I don't see how it will change the fact that you're burning oil. Mike Becker, Senior Technical Instructor

Hello Tech Mike, The toyota CE 2000, had a p0171 code which we solved last year. Now check engine light is back on. It was a quart low on motor oil and pulled a P0300 random misfire. after the oil was added, I disconnected neg terminal on battery to reset the check engine light 4 days laters it cam back on. Pulling codes P0171 and pending code P0300. I checked the fuel trims they look normal. Can low motor oil cause check engine light to turn on?

[@GoTechTraining]

Hey Alex, its possible...but why is the engine oil low? I think that's the effect, not the cause. I think you have something else going on with this car that is causing it to lose oil and run lean. I don't believe that the low oil is causing the lean code. Mike Becker, Senior Technical Services Instructor

[@alexandergonzalez2232]

Hello mike, Thank you, for response, will look into it, I have text books on engine repair. Planning to take certification exams still reviewing and reading stage getting closer to my goal. I remembered when i took the intake manifold off to replace the gasket it was noted the in piston 1 inside the head valve chambers their was a large accumulation of carbon build yet the spark plug was clean so it could not have been the piston rings, could it be the head gasket? There is not multiple miss fires, engine is smooth and humming with power fuel trims short and long are normal, oxygen sensors are normal. I did find a loose intake manifold bold loose, when I tried to tighten it it was loose so this bolt is suspect snapped when torquing. I have not fully removed yet.

[@GoTechTraining]

Hey Frank, that's up to you. The timing belt is a maintenance item that should be changed every 50 to 100K miles depending on the belt manufacturers suggestion. The jobs already part way done when doing the valve adjustment, so it makes sense to do both. Mike Becker, Senior Instructor

Awesome video as usual. I love seeing these because I can learn so much more compared to my old days without a scope. As for the hooking it up to video there may be a couple of options for you. One, which might be the most simple is to use a usb to HDMI adapter that would allow video to be mirrored to a monitor or T.V. The other option is a program called Team Viewer or one similar to it. It should allow you to do a remote screen for viewing on a monitor or T.V. as well. And yes they have the app for Android OS.

I'm having a problem with a 2009 Honda Odyssey number 1 cylinder misfire Allan misfiring fouling

[@richardshade2553]

I've been looking on the videos I don't know if there's a computer brain or should I get my valves adjusted

[@GoTechTraining]

Hey Richard, I think the best thing for you to do would be to have some testing done. I would not suggest throwing anything at this until you know what the issue is. A misfire is so broad, i'd hate to see you waste money needlessly. Mike Becker, Senior Instructor

[@mastertech8306]

Mike, awesome. I have an Acura 3.2 TL and I've noticed some roughness to it running. Nothing major so I left it alone. Last month a did a running compression with my Pico and saved the waveform. I noticed something odd about it but at the time I still didn't full know how to interpret the waveform. Heck, I didn't even know the valve lash being out could affect it that much. Long story short, I just opened the waveform and it looks just like the one in the video before the fix! I know what I'll be doing to my Acura in the coming weeks!

[@GoTechTraining]

Hey MasterTech, enjoy doing your adjustment. Should be fun. Make sure to save some known bads and some know goods. Always fun to compare the before and after! Mike Becker, Senior Technical Services Instructor

Strange issue Leslie, not sure what the deal is with that one! Mike Becker, Senior Technical Services Instructor

[@mmkkjkkkkkkkmmmm]

Great video bro!!! I have a 08 pilot with multiple misfire cylinders. I changed all spark plugs and coil. Even change 02 sensor and EGR, but engine lights are still on. I think I need to adjust those valves. What do you think? Vehicle only has 92k though.

[@mikeburton1733]

Great series Mike. I wish I had even half of your talent...... and cool tools. I know there was a way you had used some pids on your verus, like engine load, rpm, etc., and a little math to determine if engine was running at full potential. I would have liked to seen that in the before and after on this one. Just to further prove the fix.

[@GoTechTraining]

Hey Mike, I'm just faking it till' I make it! :) That's a good point. Should have seen what peak calculated load was before and after. Would have been interesting to see if there was a difference! Mike Becker, Senior Technical Services Instructor

[@mikeburton1733]

I'm sure you would have seen a difference for sure. Yes. That's it. The peak calculated load. I'll have to back and find your video that you did that. I'd like to try it out this summer when the toy comes out of hibernation.

[@eastbay40386]

Mike! Great series! I just wonder why the exhaust valves getting so tight at the same time!

[@GoTechTraining]

Hey Eastbay, gotta figure all of the exhaust valves work roughly an equal amount. So I think it would be relatively safe to assume they would share a somewhat uniform wear pattern, or tightening pattern. Mike Becker, Senior Technical Services Instructor

[@jhoodied4861]

I'm at 300k and no way to tell when maintenance was done and have developed an exhaust leak so believe this is my issue. Wish I had the tools to find out but think I'll have to just rip into it and hope it's my issue. Replaced the pcv and helped a little but think that was it's own issue being burnt up

[@GoTechTraining]

Hey Poke_Hoard, thanks for watching! At 300k, I'd be opening it it up and checking them. Chances are they need to be adjusted. I'd also suggest a waterpump and timing belt if it hasn't been done in the last 100k. Mike Becker, Senior Instructor

[@poke_hoard422]

@@GoTechTraining I appreciate the response and am purchasing some feeler gages and will be doing it hopefully sooner than later lol

[@mikechiodetti4482]

Hey Mike, GREAT VIDEO SERIES! I'm learning with my Pico Scope, will get back on that when the Spring/Summer comes back. Anyway, question. Do you need to know the cam profile in degrees to know the difference in when the exhaust valve opened and closed on the engine which gave you the difference that was seen with the scope readout? I guess my question is do you rely strictly on valve adjustment specifications, or had you/did you look at the cam profile parameters to see what the exhaust opening/closing in degrees came out to. Obviously, the adjustments using the feeler gauges proved how far off the specs were, causing the unbalance and slight lack of power in the engine. Just a thought. Honda is the only one I know that has this "mileage" adjustment. I'm pretty certain my 06 Nissan Frontier has the VVT or VCT, and the buckets in the head, so no adjustment there. The 06 Kia Sorento with the timing belt is straight up timing, no VVT or VCT, and I think it has the buckets in the head. I don't remember seeing adjustments for it. I gotta replace the "surge" tank in the Kia, it has a pin hole in it, slightly leaking coolant, and I should have done this last year, but I rolled the dice and lost this year with the ignition coils and spark plug wires, so those are next. I forgot if the upper intake manifold has to come off to do that. SIGH! Oh Well! Oh. "war story." This past year when doing all the work on the Nissan, I replaced the spark plugs and the two ignition coils on the passenger side as the intake manifold sits over them. In theory in case of misfire, hopefully it would be one of the remaining coils. Well one night after leaving home, got a terrible shake from the vehicle when pushing on the gas pedal. MIL light comes on. Quick check, P0301. That's got a new plug and ign coil. Tried something. Ign switch on, push gas pedal to floor, turn ign switch to start. Engine spins like it normally would spin, making me think its not a mechanical problem. I may be wrong, but it worked in this case. Number 1 ignition coil (harness side) connector must not have been fully "locked" on to the ignition coil. It took some effort to get it on, so I checked, no bent pins or dirt/debree, so I pushed it on. It's in a not so forgiving place. It worked, its still holding, runs great, so either I didn't put it on tight enough when reassembling, or it did come off. If it happens again, I'll see if the replacement connector I got for it will be the cure. I hope you have a GREAT CHRISTMAS and NEW YEAR'S. I'll bet your son can't wait for Santa Claus now! How old is he now? Take care Mike

[@GoTechTraining]

Hey Mike, thanks!!! Generally, the exhaust valve should open within a certain degree window from bottom dead center. If I remember right I mentioned that number in the video. In the scope capture, I was mostly looking at where the waveform went from declining to flat-line to increase in pressure while the piston still traveled down. This tells me that something in the cylinder changed...exhaust valve opened. Ahhh the old Kia "surge tank"...what a name for an intake plenum haha. My son is just over a year and a half now. He still doesn't quite know who Santa is yet...but he knows that he says "ho,ho,ho" :) Merry Christmas and Happy New Year to you as well! Mike Becker, Senior Technical Instructor

[@vardanpetrosyan6293]

Hi Mike. Just 2 questions, how much you charge for diagnostic and for adjusting the valves

[@GoTechTraining]

Hey Vardan, generally speaking, diag is an hour. Sometimes you can pull more but that's between you, the shop and the customer. As far as adjusting on this van...book time is 4.3 hours on here. Mike Becker, Senior Technical Instructor

Yo is the 3.7 l acura tl 2013 engine the same as 0.08 mm intake and exhaust 0.12mm ?

[@enegron6987]

Great video series thanks✨just bought this exact same vehicle make year and problem. 2weeks ago the guy sold me on the fact he just changed the timing belt power steering water pump and pressure line. Felt great 1st 324.5 miles got stuck on hwy. Changed the electronic throttle body then the starter. Drove around 20+ miles started to hear slight ticking that turned into louder clacking last night changed the spark plugs and ignition coils all new. Now it sounds like something is loose in the engine so I saw your video series and got a great understanding of what seems to be happening but I’m afraid it is not good. Is it possible the loud clacking which started as the ticking noise in your video is a broken valve? I really appreciate your videos you’re a really great teacher thank you for any input. Ed

Now show us how you're getting the dent out of that right front fender! Just kidding Mike! Great conclusion video with noticeable difference on the scope! Selling a valve adjustment with a capture from the scope, would leave the customer in complete astonishment,there's no way he'd say " NO " to that! Lol!

[@GoTechTraining]

Hey Nick, I don't have patience for body work. Never have, never will. Washing and waxing the only reason I touch paint haha! I think in this case the customer would think we were speaking a foreign language. At the end of the day just showing them the maintenance chart should have probably sold the job...but it felt like too much of a "guess" for me. I need proof before I can sell a job.

Hey Welding Junkie, yeh I use the PICO WPS. Great tool! I highly recommend adding it to any good diagnostic arsenal. Mike Becker, Senior Technical Instructor

[@marinkojezabek2555]

Any one know if this could be diagnosed without a pressure transducer and scope. Or would it be just a matter of performing the scheduled tune up at required time. Also, I would like to hear if anyone has had experience with worn camshafts and the effects this has on fuel trims and the setting of codes.

[@GoTechTraining]

Hey Marinko, that's a great question. At the end of the day this is a maintenance item...and could be sold as such. I wanted to prove it. I'm not certain on a conclusive way to find these valves being slightly out without a scope. I'm open to ideas! Mike Becker, Senior Technical Services Instructor

[@ebuzek3648]

shouldn't this have been confirmed before the timing belt change? The belt could be slightly stretched causing the longer duration?

[@GoTechTraining]

Hey E Buzek, did you watch Part 1? In that I explain the diagnosis a bit further. A timing belt will not make a valve open early and close late. A timing issue would open a valve early or late and then close it early or late. Mike Becker, Senior Instructor

I cleaned the egr valve passages, new egr valve, cleaned all the air intake all new gaskets as well as all new fule injectors, spark plugs and coil packs. Sadly still miss on those two cylinders so this or my valves are stuck or burnt. She no longer runs, will keep posted.

I must be on a roll :) Another pointer to exh valve clearance was that manifold vaccum was perfect, despite poor compression. You'd guess I'm old school :) & my cars are regularly maintained. I'd guess the Honda owner was punished enough for neglecting 105,000 mi valve adjustment - esp that this Honda didn't have the dreaded bucket & shim DOHC. He won't make that mistake again :)
