Because there is no self adjustment on J37A engines (and on many other 6 cyl Honda engines), as there are no hydraulic lifters. It's manual adjustment. And I can assure you it's needed at higher mileages as clearly seen in this detailed guide. Unless you don't care about the noise, loss of compression and worse gas mileage in case of loose clearances and valve eating into the seats (which is permanent damage) in case of clearances that are too tight. I hope this helps!
@@AcuraAddictedyes sir I had mine knocking at 109,000 miles and all mechanics were saying rod knock so I replaced the engine bought 1 with similar miles for $640 & $800 for installation but I kept the old engine to take apart and investigate 😅😅 and valve lifters were knocking
One of the best videos I've watched in valve clearance adjustment. I'm confident to do now the acura mdx 2009 valve adjustment. Thank. You very much for this sharing. Our lord Jesus has blessed the work of your hands sir.. Greatful and appreciate this video very much. Two thumbs up. 👍👍
💯💯💯🙌 I wish he did work here in Philly. I would happily have him work on my 09 mdx. I get excited everytime a new video comes out. Great camera angles and work. 💪You always go above and beyond Bogdan 👍
@@edde333 Thanks! Actually now that I've done it twice, it doesn't seem that complicated anymore. So as long as you are attentive to details and take your time, it's absolutely a DIY!
FANTASTIC video. Just used this information to adjust the valves on my 06 MDX. Runs perfect and no more check engine light for multiple cylinder misfires
@@AcuraAddicted amigo!!!! Cual es la medida de cada parte? 0.30mm exaust 0.22mm intake ¿? Mi motor es un j37 2007 mdx. Estas son las medidas correctas?
Your tutorials are all so thorough and excellent. I really appreciate how succinct you are in your explanations and actually naming parts. I use your tutorials all the time working on my 2012 MDX, and i appreciate all the time and effort you put into filming these. I have fone all of my own maintenance on this car for the last 5 years, and the valve adjustment is next on the list. Thanks!
Hey my youTube mechanic and friend...I just finished step by step a valve adjustment....and I did well just because of you. It took me around 10 hours in my Acura TL 2005. Thank you so much. Two thumbs up 👍👍 Thank
Many thanks Bogdan. All of your videos are first rate and easy to follow. I used this one when I found oil leaking into a spark plug tube. It was a lot of work to fix that small problem, but I changed a lot of gaskets and cleaned up much gunk also in the process. My 2007 MDX Tech has 204,000 miles and is going strong.
My hat goes off to you, thank you for sharing this amazing video. I am actually a huge fan of the J37, i own a MDX 2011 SH-AWD with 100k miles and this tank as i like to call it can move only because of such an amazing engine with plenty of power. I cannot imagine how many engines you have taken a part, clearly you are a master of your craft. You took time to explain and show us exactly what you were doing with high precision. Thank you, we appreciate you sharing your knowledge with us.
Thank you for your kind words, Daniel. Believe it or not, this was the second time I got the covers open (first time was in 2014). The vast majority of the maintenance and repairs you see on my channel is filmed when I'm doing the procedure for the first time. That's why it takes so much time to film and edit after. Once again, thanks!
As professional as it gets. And don't worry, it's taking me about 200 hours to get the spark plug tube seals out hahah.....much prefer working on my Mercedes, so much more straightforward. However thanks to videos like this, my mom's tl can get the love it needs
wow truly amazing videography and your technical skills are clearly understood for those of us that want to learn the intricate parts of doing the job correctly.
Thank you so much. This is very detailed such that no one would mess up. ❤ Would apply this great knowledge this weekend for my acura mdx 2006 valve adjustment.
Great video AA, I've seen guys that found the hose between the intake and the front valve cover to be plugged(6:19) with the sludge/Blowby moving through the engine crankcase to the intake. That short hose sees most of it and will carbon up inside. Synthetic oil is a good way to cut down on the blowby and a good 10W-30 will help seal the rings better. I'm in Texas and use 10W-40 to compensate for the heat a little better. I found #2 cylinder had wiped the Cam Lobe and severe clicking noise on that Exh. Rocker. Had to replace both cams and a couple of rockers and it's been fine since. 288K+ miles.
Thks for this video I have a 2009 acura mdx , and it's mistfiring. Changed coil packs and plugs still doing it. I will try this now. Thks slot you saved me slot of money.👍🍺
The service manual says Exhaust is 0.28-0.32mm (0.011-0.013), Intake 0.20-0.24mm (0.008-0.009in) so it is a range so don't sweat it if you can't find 22 & 30 as video list the mid point only... Also those 10mm bolt should be torqued back at 20Nm/14lbf-ft - I should have checked it before as I likely didn't torque them enough with my short 10mm wrench (had to use a socket to loosen many of them). I would also highly suggest doing 4,5,6 and opening only one side at a time and doing the front first to get good practice as the back is so much harder. No reason to go back and forth and cover things to prevent debris from falling as you go back and forth. Also painters tape works better at sealing the intake than shop towels IMO.
Hi Bogdan: Good to see you back in action. Hope you have been well. I am thinking of making a trip to Toronto sometime in October if the road crossings are open by that time. Will be in touch then to see if we can get together for a coffee or something. Stay safe. Harish
Man it’s GREAT to have you back Bro, seriously I would’ve never attempted any of the repairs I’ve done to my 2012 MDX without your videos and guidance. Also thank you for adding your knowledge to questions I’ve asked on MDX’ers forum, I am MDXTreme24. Your Awesome, B, and your videos especially this one are GREATLY APPRECIATED. 🤜🏾💥🤛🏾 much Love All the way from PA... Real quick, I’m getting a smell like a fresh book of Matches from my MDX, not eggs, no codes, I’ve only switched my oil to a full synthetic oil. Also no smoke 💨 weird,
Thank you for the feedback! You might have spilled a little oil somewhere and it’s burning. Should go away. If it doesn’t, Synthetic oil is thinner than the regular blend, so it can seep through some seals and burn. Check for leaks.
Great video man! Glad to see some new stuff. I'll be doing an elite to sport swap on my 2012 soon and your videos have been a great source of knowledge!
@@AcuraAddicted thanks again for this tutorial and all the others. i have the same exact car so these are god send. honestly the best car step by step tutorials on the web
Another great video, great diy, thank you. I Have owned a gen 2 MDX for many trouble free years @ over 240k miles now. (it’s on my you tube channel btw). Will be upgrading when the new generation arrives but will still keep my gen 2. @AutoFixEZ
Fabulous!!! I need really to do this! But I have low compression in all cylinders, trying not to have to replace the engine.. the head gasket most likely blown. And oil everywhere in the head cover 🤦♀️
Do you remember if any of your valves were out of adjustment to speak of? Been a while, but since you’re responding to many questions I thought I’d ask. I bought my 2006 MDX used and the previous owner had all his maintenance done at the Acura dealer…(one reason I bought it because it was highway miles and the owner did all the fluid changes at the dealer when due). The MDX had 306,000 on it and still the original timing belt as the dealer had no record of putting it on, as they never suggested it to him and he’s not mechanically inclined to think of such things. So of course it has a new one in it now. But going that mileage to me was a testament to the quality of the part and engine (or that God was just watching over him:). Thought you’d be amazed so fyi. I’m sure the valves have never been touched. It runs great, and they asked about the valves, when I had the dealer do the timing belt, but seems like they weren’t going to give me a break on the labor, even though they had it already apart, so I passed on it, cause I was already putting out $1,000 and wasnt that excited about another 7-800 the same day. I’m not worried about the valves, but it is something I think about once in a while. I do expect this car to hit 400,000. Has 324,000 currently.
Yes, some needed adjustment at 180K miles. Loose ones are fine, but it's the tight ones you should be worried about, as when they start diggint into the seats, it's a point of no return.
@@AcuraAddicted ok thanks for that… I’ll look to get that done. Be a few weeks though and if the world hangs together that long. I’ll report back with how bad they are out. You talked me into it. ;)
Excellent video man best one on the web. Question throttle body if you disconnect it at sensor point do you need tondo relearn process or just disconnect it and don’t touch the butterfly. This is much same engine as my 2015 pilot J series engines ?
Great, well doe video! If only all other DIY vids were as well done and thorough as this. My only question is would these steps and measurements apply to a 2015 MDX Base model? to a 2012 Accord?
Hi John. Thanks! The steps should work for most Honda V6 engines with slight variations (so make sure you have access to reliable information for your specific vehicle such as this one which is taken directly from the OEM Service Manual). Same goes for clearances.
Nice to see you back after a long time! As much I enjoyed watching this detailed video, I kind of missed as to what are the symptoms/Issues when ww should think of doing all this. Lately I am smelling oil from exhaust when I start my car in my Garrage. You think I might have some oil leaks from any of these gaskets?
Thanks! You really want to check and adjust clearances at least every 100K miles with the TB service. While the usual symptoms are noisy valves, you might not have any, but you still want to do this. If the valves are too tight, they start to eat at the valve seats, which can lead to engine damage and in a lot of cases an irreversible process once it started. As for your oil smell, that's not good. It might be oil seeping from under the valve covers and onto cats. But it can be worse - oil getting into cylinders and burning there, which means you might have a piston ring problem. 2010-2013 models are prone to that issue. I would get someone knowledgeable have a look.
170K miles. Mixed driving. Note I make full stops at all stop signs and red lights befor turning right. Pennzoil Synthetic Ultra 5W-20 since 2014. Acura OEM dealer blend before that.
With time valves go out of adjustment on engines without hydro compensation (such as this one), meaning loose valves will become noisy and tight ones will eventually start eating into their seats (which is irresistible and inevitably leads to engine damage).
Cleaning the egr port: can you spray the hole with cleaner and scape with screwdriver?I'm hoping doing this job clears up the noise coming from the engine,I don't have a tripod or I would have filmed
What is stuttering sound on RLX. it's mainly at idle but hear it bow when driving. So many questions and no mechanic can hear what I know is louder sound than normal..any recc
Instead of a rubber puck, could you use a socket to install the spark plug tube seals? Also, if doing this job with a timing belt change, would you recommend doing one job first vs. another? Thanks for the great video!
You can, but you have to be careful as the rubber seals are very soft, make sure you don’t tear them when installing. As for the TB, this job has no common elements or parts that would reduce time doing them either, so you can do them separately or together, it makes no difference.

Здравствуй Богдан. Приехал к знакомому на mdx 2011, сказал что нужно зазоры подтянуть, на итоге проблема так и осталась непонятный треск в районе первого цилиндра,не могут разобраться механики не сталкивался такой проблемкой.
Приветствую! Что значит подтянуть? Только впускные клапаны обычно нужно подтягивать, выпускные обычно наоборот - ослаблять, ибо они обычно слишком тугие со временем. Специалисты точно надёжные? И что значит треск? Есть запись звука?
Thanks! I get all my OEM parts from the dealership in Toronto. If you are in US, you can order them online from multiple sources at a great discount (online OEM parts are not available in Canada).
when you set the crank to top dead center did you ever move it again? I guess what I'm asking is do you need to move the crank to a new spot every time you move to the next cylinder? Before I try this I just wanted to say that I have a miss on cylinder 5, I have replaced the Coil the plug, and the fuel inj- , Do you think that the valve Adj might fix my problem, I am getting spark and fuel to that cyl,
Yes, I did, as depicted in the video. I also provided the location of all cylinders, so it's clear which one to measure/adjust when the relevant cylinder TDC is aligned.
ok thank you, i did not know what else to try, I'm not going to hold you to it but after all of the other stuff that I've already tried do you think that this might be my problem?
@@williamtreat5893 Tight clearances can cause misfires, but I wouldn't rule out other reasons. If you already know you have a known good spark plug/coil and the injector works as expected, if your MDX is 2010-2013, the most likely cause of the misfire would be piston rings, it's a typical issue on 2010-2013 MDXs. You can also have a broken valve or more. Broken valves are easier to diagnoze than bad piston rings (you only need a $40 camera to inspect them through the spark plug hole).
Thanks! While it’s impossible to convey what the feeling should be, but there should be a slight drag. To a point when it’s still sliding but dragging, not catching and getting suck. And definitely NOT not fitting - that means it’s way too tight and needs to be loosened. Most important thing to remember: loose are better than too tight. When they’re too tight, the valves will start digging into the seats. When they’re loose, they’re just noisy.
@@AcuraAddicted thank you for replying so quickly. I have a TSX and on cold acceleration I can hear rattling /clanking noise. I think the valves are loose and need adjusting.
Rattling or clunking may not be valves related. First thing to check is the rotted/loose cat shield(s). Also, if you’re going o adjust your valves, make sure you’re following the correct clearances for your TSX as it may be different for your engine.
@@AcuraAddicted It could also be piston rings. 2009-2014 Tsx had issues with oil burning. Do you typically go to the lower tolerance or in the middle. For example for my tsx intake side is 0.21-0.25mm. Do you set them to 0.21 or 0.25mm
Will this be the same for a 2010 Acura TL SH-AWD I can’t seem to find a video illustrating how to do a valve adjustment on that year and model please thank you
The valve adjustment should be similar on Honda engines. However valve clearances may vary, so you need to make sure you follow proper valve clearances. They are usually indicated on a sticker of the hood.
Hello Bogdan I own two MDXs one is an 08 with 135k miles runs very well & I just got another one an 07 with 232k miles & it’s pulling codes P300, P301, P302, P303, P304, P305 & P306 I’ve replaced all spark plugs & 2 ignition coils which didn’t look good but I’m still having misfire issues. I was told to get a valve adjustment done and I’m thinking of doing this next weekend do you know if this will help clear the misfires? The car is in good shape other than the previous owner used 87 octane gas ⛽️ instead of 91 octane as recommended. Your advise will be highly appreciated.
Hello, and thank you for sharing! Yes, tight vavles can cause misfires. Unfortunately, this likely means they have passed the point of no return if it's the valves, meaning they might have started to eat at the valve seats. In any case I would try measuring and adjusting first and see if that resolves the issue.
I have a 2006 Acura MDX they did the valve adjustment on my car but I still hear a little bit of the lifters a little bit the codes went away I have no more codes but I still hear the lifters making a little bit of noise ticking noise is that normal
Without hearing what the noise is I woulnd't be able to tell, but you might have gotten the adjustment too late (when the valves start to dig into seats).
Exhaust valves are on the outside of the engine (so firewall side for the rear head and radiator side for the front head). Intake valves are on the inside of the engine (both close to each other divided by the middle of the engine). You do not need to keep track of exhaust VS intake. They are not mixed and will always be uniform: one side of each head are exhaust, the other side of each head are intake. It's pretty clear from the video and camera multiple angles.
I would have it done ASAP. Depending on severity you might drive it, but after the point of no return (when the valves start digging into valve seats) it will be quite an expensive repair, basically replacing the entire head (or both). Labour alone would be astronomical.
@acuraaddicted how are you today ? I have a question maybe you can help me like everytime had you ever cleaned the intake valve in your MDX and the fuel injectors ? And if yes what’s you use to do it? Thank you
Hi Bogdan, My 2008 MDX has a problem with a long start when the engine worm. It means the first start in the day very ok. But from the second, sometimes it has a long started with time longer 2 times normal. Do you have any advice for me?
Hello! I haven't had this issue, but it can be a number of reasons. Could be fuel delivery system, battery or ground connections, etc. Worth seeing a mechanic and diagnosing first.
Thank you. Remarkable detail ! Anyone here attempt same on an 05’ mdx? Any overt difference in process besides listed parts numbers and valve adjust specs?
The procedure is the same minus some potential different bolt locations, etc. I don't know about clearances, though, you'll have to look that up on your own. I don't have a service manual for the first gen, so I can't take the responsibility and be 100% sure. I suggest getting a Honda service manual subscription and getting the info directly from the source or asking your local Acura dealership if you have someone there.
Why?? Self adjustment... waste of time.. unlessvu have time and money to give to stealerships... lol
Because there is no self adjustment on J37A engines (and on many other 6 cyl Honda engines), as there are no hydraulic lifters. It's manual adjustment. And I can assure you it's needed at higher mileages as clearly seen in this detailed guide. Unless you don't care about the noise, loss of compression and worse gas mileage in case of loose clearances and valve eating into the seats (which is permanent damage) in case of clearances that are too tight. I hope this helps!

Do you remember if any of your valves were out of adjustment to speak of?
Been a while, but since you’re responding to many questions I thought I’d ask.
I bought my 2006 MDX used and the previous owner had all his maintenance done at the Acura dealer…(one reason I bought it because it was highway miles and the owner did all the fluid changes at the dealer when due).
The MDX had 306,000 on it and still the original timing belt as the dealer had no record of putting it on, as they never suggested it to him and he’s not mechanically inclined to think of such things.
So of course it has a new one in it now. But going that mileage to me was a testament to the quality of the part and engine (or that God was just watching over him:). Thought you’d be amazed so fyi. I’m sure the valves have never been touched. It runs great, and they asked about the valves, when I had the dealer do the timing belt, but seems like they weren’t going to give me a break on the labor, even though they had it already apart, so I passed on it, cause I was already putting out $1,000 and wasnt that excited about another 7-800 the same day.
I’m not worried about the valves, but it is something I think about once in a while. I do expect this car to hit 400,000. Has 324,000 currently.
Yes, some needed adjustment at 180K miles. Loose ones are fine, but it's the tight ones you should be worried about, as when they start diggint into the seats, it's a point of no return.
@@AcuraAddicted ok thanks for that… I’ll look to get that done. Be a few weeks though and if the world hangs together that long. I’ll report back with how bad they are out. You talked me into it. ;)
Awesome Videos as always!
Thank you!
Hey B good job fams very good education my friend tim from Nyc.
Thank you!
Great job 👏🏼
You are the best! Thank you.
Excellent video man best one on the web. Question throttle body if you disconnect it at sensor point do you need tondo relearn process or just disconnect it and don’t touch the butterfly. This is much same engine as my 2015 pilot J series engines ?
Thanks! As long as you do not touch the butterfly, you don't need the re-learn position procedure.
Thanks, a great help
No problem!
Tanks for help because im jabe un Problem exactly
Many thanks Bogdan! Timing belt video coming soon???
Thanks! TB and pump reseal is done about 3 weeks ago. The video will probably take as much, if not more, so I would not expect it until mid fall.
@@AcuraAddicted do you recommend to change camshaft seals as well? mine do not leak and i would probably try to keep the whole process simple
What is the Hondabond needed for on the 2010-2013 models? Where is it used? Great channel! By far, the best Acura videos out there. Thanks.
Thanks! I believe it's the same Hondabond.
Ese mantenimiento cada cuantos kilometros es recomendado hacerlo
Saludos desde Monterrey Mexico
Great, well doe video! If only all other DIY vids were as well done and thorough as this. My only question is would these steps and measurements apply to a 2015 MDX Base model? to a 2012 Accord?
Hi John. Thanks! The steps should work for most Honda V6 engines with slight variations (so make sure you have access to reliable information for your specific vehicle such as this one which is taken directly from the OEM Service Manual). Same goes for clearances.
Nice to see you back after a long time! As much I enjoyed watching this detailed video, I kind of missed as to what are the symptoms/Issues when ww should think of doing all this. Lately I am smelling oil from exhaust when I start my car in my Garrage. You think I might have some oil leaks from any of these gaskets?
Thanks! You really want to check and adjust clearances at least every 100K miles with the TB service. While the usual symptoms are noisy valves, you might not have any, but you still want to do this. If the valves are too tight, they start to eat at the valve seats, which can lead to engine damage and in a lot of cases an irreversible process once it started.
As for your oil smell, that's not good. It might be oil seeping from under the valve covers and onto cats. But it can be worse - oil getting into cylinders and burning there, which means you might have a piston ring problem. 2010-2013 models are prone to that issue. I would get someone knowledgeable have a look.
How many miles were on this engine??
What type of driving? highway, city, mixed??
What type of oil, synthetic or regular??
170K miles. Mixed driving. Note I make full stops at all stop signs and red lights befor turning right. Pennzoil Synthetic Ultra 5W-20 since 2014. Acura OEM dealer blend before that.
MAGA ... you took my Slogan !!!
Please don't sue me 😅
All these mechanics were saying rod knock and it was this 🤦🏻♂️
Come to Atlanta and do this my 2013 MDX! Lol
Haha! Actually, don't mind if I do. Just don't have any time whatsoever!
Acura Addicted so what does this do for the engine? Smoother?
With time valves go out of adjustment on engines without hydro compensation (such as this one), meaning loose valves will become noisy and tight ones will eventually start eating into their seats (which is irresistible and inevitably leads to engine damage).
Cleaning the egr port: can you spray the hole with cleaner and scape with screwdriver?I'm hoping doing this job clears up the noise coming from the engine,I don't have a tripod or I would have filmed
Yes, that’s possible
Got a real problem u helped me before 02 mdx bottom alternator bolt broke off stuck in engine any thoughts mayne raise engine to reach and tap out?
I’m curious why you don’t move the harness out of the way? It would be much easier to work without them getting in the way.
It does not interfere with the work at all, no sense in removing it.
What is stuttering sound on RLX. it's mainly at idle but hear it bow when driving. So many questions and no mechanic can hear what I know is louder sound than normal..any recc
It would be impossible to say without at least hearing the sound.
Instead of a rubber puck, could you use a socket to install the spark plug tube seals? Also, if doing this job with a timing belt change, would you recommend doing one job first vs. another? Thanks for the great video!
You can, but you have to be careful as the rubber seals are very soft, make sure you don’t tear them when installing. As for the TB, this job has no common elements or parts that would reduce time doing them either, so you can do them separately or together, it makes no difference.
My 08 Acura needs this. What exactly is the purpose of this maintenance service ?
You really want to check and adjust clearances at least every 100K miles with the TB service. While the usual symptoms are noisy valves, you might not have any, but you still want to do this. If the valves are too tight, they start to eat at the valve seats, which can lead to engine damage and in a lot of cases an irreversible process once it started.
Acura Addicted got it. Thank you
Здравствуй Богдан. Приехал к знакомому на mdx 2011, сказал что нужно зазоры подтянуть, на итоге проблема так и осталась непонятный треск в районе первого цилиндра,не могут разобраться механики не сталкивался такой проблемкой.
Приветствую! Что значит подтянуть? Только впускные клапаны обычно нужно подтягивать, выпускные обычно наоборот - ослаблять, ибо они обычно слишком тугие со временем. Специалисты точно надёжные?
И что значит треск? Есть запись звука?
Where did u go and get all the parts just wanna know if u went to dealership or somewhere else great video
Thanks! I get all my OEM parts from the dealership in Toronto. If you are in US, you can order them online from multiple sources at a great discount (online OEM parts are not available in Canada).
when you set the crank to top dead center did you ever move it again? I guess what I'm asking is do you need to move the crank to a new spot every time you move to the next cylinder? Before I try this I just wanted to say that I have a miss on cylinder 5, I have replaced the Coil the plug, and the fuel inj- , Do you think that the valve Adj might fix my problem, I am getting spark and fuel to that cyl,
Yes, I did, as depicted in the video. I also provided the location of all cylinders, so it's clear which one to measure/adjust when the relevant cylinder TDC is aligned.
ok thank you, i did not know what else to try, I'm not going to hold you to it but after all of the other stuff that I've already tried do you think that this might be my problem?
@@williamtreat5893 Tight clearances can cause misfires, but I wouldn't rule out other reasons. If you already know you have a known good spark plug/coil and the injector works as expected, if your MDX is 2010-2013, the most likely cause of the misfire would be piston rings, it's a typical issue on 2010-2013 MDXs. You can also have a broken valve or more. Broken valves are easier to diagnoze than bad piston rings (you only need a $40 camera to inspect them through the spark plug hole).
@@AcuraAddicted 2005 the suv runs great a miss on cyl #5 I did change the plug in and coil
I have 176,000 miles on my 03 MDX. I may need to do this! Did you notice any performance or mpg increases after?
No, and you shouldn't expect that either. It's more about making sure your engine works within specs for longevity.
Can you make a video how to install oil catch can
No. I won’t be installing one (I don’t need it), so there’s not going to be a video.
Great video!
When adjusting valve lash is it safe to say that if you adjust if t properly next size up of the filler gauge should not fit?
Thanks! While it’s impossible to convey what the feeling should be, but there should be a slight drag. To a point when it’s still sliding but dragging, not catching and getting suck. And definitely NOT not fitting - that means it’s way too tight and needs to be loosened. Most important thing to remember: loose are better than too tight. When they’re too tight, the valves will start digging into the seats. When they’re loose, they’re just noisy.
@@AcuraAddicted thank you for replying so quickly. I have a TSX and on cold acceleration I can hear rattling /clanking noise. I think the valves are loose and need adjusting.
Rattling or clunking may not be valves related. First thing to check is the rotted/loose cat shield(s). Also, if you’re going o adjust your valves, make sure you’re following the correct clearances for your TSX as it may be different for your engine.
@@AcuraAddicted It could also be piston rings. 2009-2014 Tsx had issues with oil burning. Do you typically go to the lower tolerance or in the middle. For example for my tsx intake side is 0.21-0.25mm. Do you set them to 0.21 or 0.25mm
Always aim for the middle
Will this be the same for a 2010 Acura TL SH-AWD I can’t seem to find a video illustrating how to do a valve adjustment on that year and model please thank you
The valve adjustment should be similar on Honda engines. However valve clearances may vary, so you need to make sure you follow proper valve clearances. They are usually indicated on a sticker of the hood.
Hello Bogdan I own two MDXs one is an 08 with 135k miles runs very well & I just got another one an 07 with 232k miles & it’s pulling codes P300, P301, P302, P303, P304, P305 & P306 I’ve replaced all spark plugs & 2 ignition coils which didn’t look good but I’m still having misfire issues. I was told to get a valve adjustment done and I’m thinking of doing this next weekend do you know if this will help clear the misfires? The car is in good shape other than the previous owner used 87 octane gas ⛽️ instead of 91 octane as recommended. Your advise will be highly appreciated.
Hello, and thank you for sharing! Yes, tight vavles can cause misfires. Unfortunately, this likely means they have passed the point of no return if it's the valves, meaning they might have started to eat at the valve seats. In any case I would try measuring and adjusting first and see if that resolves the issue.
I have a 2006 Acura MDX they did the valve adjustment on my car but I still hear a little bit of the lifters a little bit the codes went away I have no more codes but I still hear the lifters making a little bit of noise ticking noise is that normal
Without hearing what the noise is I woulnd't be able to tell, but you might have gotten the adjustment too late (when the valves start to dig into seats).
How to tell difference between intake valve and exhaust valve? Do you just track where it goes and easily distinguish which valve it is?
Exhaust valves are on the outside of the engine (so firewall side for the rear head and radiator side for the front head). Intake valves are on the inside of the engine (both close to each other divided by the middle of the engine). You do not need to keep track of exhaust VS intake. They are not mixed and will always be uniform: one side of each head are exhaust, the other side of each head are intake. It's pretty clear from the video and camera multiple angles.
@@AcuraAddicted cool that helps!
@@AcuraAddicted only valve adjustment I ever did was on a single cylinder OHV engine
Is it good to keep driving if you need this done on your car?
I would have it done ASAP. Depending on severity you might drive it, but after the point of no return (when the valves start digging into valve seats) it will be quite an expensive repair, basically replacing the entire head (or both). Labour alone would be astronomical.
@acuraaddicted how are you today ? I have a question maybe you can help me like everytime had you ever cleaned the intake valve in your MDX and the fuel injectors ? And if yes what’s you use to do it? Thank you
Hi Hansell. I'm good, thank you for asking! Never had to clean either intake valves or fuel injectors. Sorry!
Ok thank you so much. Have a great day
Hi Bogdan, My 2008 MDX has a problem with a long start when the engine worm. It means the first start in the day very ok. But from the second, sometimes it has a long started with time longer 2 times normal. Do you have any advice for me?
Hello! I haven't had this issue, but it can be a number of reasons. Could be fuel delivery system, battery or ground connections, etc. Worth seeing a mechanic and diagnosing first.
Thank you. Remarkable detail ! Anyone here attempt same on an 05’ mdx? Any overt difference in process besides listed parts numbers and valve adjust specs?
What is the name of the tool you use for measurement??
Feeler Gauge. You'll need ones that will allow to measure 0.30mm and 0.22mm gaps.
@@AcuraAddicted thanks man
@@AcuraAddictedif I don’t have .22 what else can I use?
You can use whatever that will allow you to measure 0.30mm clearance on exhaust valves and 0.22mm clearance on intake valves.
Are these spec info and procedures same for all Acura MDX , I have 2003 mdx
The procedure is the same minus some potential different bolt locations, etc. I don't know about clearances, though, you'll have to look that up on your own. I don't have a service manual for the first gen, so I can't take the responsibility and be 100% sure. I suggest getting a Honda service manual subscription and getting the info directly from the source or asking your local Acura dealership if you have someone there.
@@AcuraAddicted thanx , looks easy but worry doing it wrong or forgotten to do certain things afterwards.😅
Where in DE/PA I can get this done
No idea, sorry.
