@ahcgarage do you have any videos which shows me how to just remove the 07 Acura MDX suv engine without the front wheels and axles and the bell housing from transmission? And are the 04 and 06 model MDX engines both compatible with the 07 model for a engine only swap ? Or are there any mods which prevents use? What are the compatible motors which can be used in place of the 07 model MDX..........04 and 06 model MDX engines ??? Thank you
As to the cam failure I question the brand of oil that they were using. The coking of the oil rings I have seen before. I find the harder you wind up the engine the less coking you will see in the oil rings. I started working on Honda engines in the early 70's and continued till the first part of 2000. I was told that Honda engines love high rpm's. I often had to replace the rings and rod bearings around 1 hundred thousand miles or sooner. Those people that drove their engines harder did not seem to need it that early. I now own an 2020 MDZ all wheel drive with the 3.7L engine and I always use genuine Honda oil and parts on my cars. They seem to last longer that way. I am now in my 80's and will not be driving that much now, but I still take it out and give it a good work out to keep it happy. Love your show and good narration of the program.
Excellent video with top notch Techncian that knows his stuff and has the delivery of a great teacher! Thank you for all your hard work creating this video and sharing with the UA-cam community.

@@Scoot7827 you are seriously delusional if you think HONDA would EVER and I mean EVER use a part off a fucking mopar lmao I swear fucking brain dead they don’t even use other companies transmissions and have always made their own shit and you think they’d use a part off a fucking glorified fiat
This video deserves more views! And some people doesn’t understand cheap gas on their performance engine will cost them more at the end, in this case, engine swap! Looking at those carbon built up almost made me cry!!
The carbon buildup is due to the piston rings being the wrong ones for this engine. Also, apparently system design had something to do with the oil burn and carbon buildup as well. Virtually all of the 3.7 L engines are oil burners. This is well documented.
@@nickr5658 exactly this, besides, almost all V6 engines made by Honda since 2003 have extreme oil burning issues. There are thousands of complaints online regarding this, where every 1k miles driven, requires 1Qt of oil added. Not adding oil before the 5k means not having oil in the engine and completely destroying the engine, as these take 4.5QT.
On a cold start of my 08 TL Type S, I won’t drive off until my NAV Display automatically turns off (maybe 30 seconds or so). Another technique I use on very cold starts is to watch my RPM drop from approx 1100 to 700 (idle RPM warm).
I do exactly same thing on my 07 TL type s. I wait for minimum 1k rpm drop. Usually 30 seconds or a min. And also synthetic oil. 350k miles on mine. Still running good
I let my Acura drop to at least 1100 so it doesn’t jerk so hard when you put it in gear engines aren’t meant to have load put on them that early no matter what people say
Excellent vid... thanks! I have four Honda/Acura vehicles with J35 V6 engines... oldest is 2013 Accord at 126K miles, and all run like new. 🤞 I have heard that the J37 Aluminum bores are the achilles heal of that engine as the miles add up... they score and burning oil is the usual failure mode. Surprised to see cam lobe wear... could that happen to any J series engine?
I’ve JUST done the timing belt on my 4th gen TL, knew EXACTLY the car when I saw the top lol. Really cool to see the inner workings inside the engine, even MORE so glad I went with the FWD. absolutely LOVE the 4th gen TLs
Those motors are also notorious for scouring the cylinder bores due to the sleeve material and lack of proper oil changes also lack of proper octane fuel usage
FYI: The EGR T-pipe bolted down inside the intake manifold distributes the exhaust directly into the two intake plenums on either side. It does not route exhaust to the 6 holes in the top of the intake manifold. Instead those 6 holes and it's channel are the vacuum path for the PCV system. The blue PCV valve on the on the front valve cover regulates the vacuum while the chambers across the top of the valve cover separate oil from crankcase vapor. The vacuum hose on the passengers side then connects the valve cover to the 6 ports in the intake manifold. As soon as you removed the intake manifold cover I could tell the owner was not changing the oil on time. The channel with it's 6 ports should have been cleanest nearer that vacuum hose.
Y’all didn’t mention that these 3.7 have vtec on both intake and exhaust valves, when all single cam Honda engines only have vtec lift on the intake valves. If you ever have taken a vtec d series or J3.0-3.5 valve cover off you’d see it’s a lot more simple then the 3.7 engine. I was hoping y’all explained how the rocker arm assembly worked on that engine with a little more detail. It somehow locks both intake and exhaust rocker arms together on a bigger lobe.
Yeah, I’ve always wondered how Acura/Honda pulled this trick off. While other manufacturers put two cams per cylinder bank on their V6 engine designs for a version of dual VVT. Acura employs an elegant trick to achieve the same thing with a SOHC design. No one has taken these engines apart & explained exactly how certain versions of the J-series work in detail. Many videos on this engine treat all J-series designs as the same… when in fact Honda/Acura have been improving their V6 engine non-stop since day one.
I've also found out not all premium gas is the same..from now on I'll go directly to one of the oil/gas companies, rather than Cuz'n Jed's or some grocery store gas station. My engine used to make a ticking sound, then my dealer said change where you get your gas. I had already had a valve adjustment earlier in the year. No more ticking noise
Nice video. Our Turbo 06 Accord J35A7 Swap makes 550whp on just 8psi. We (HalferLand Performance) specialize in everything Honda Jseries Performance related 🤙
We've found customers aren't changing their oil in proper intervals. Oil companies are advertising 10k miles which is WAYYYY too long. At 10k you'll get carbon build up and your cam lobes getting chewed up like this.
Thanks for going to the effort to make this video. I subscribed after recently discovering your channel late last year. Even though I don't have a J37 myself, this is some fantastic content that is much appreciated.
I'm really glad I stumbled across this video as I own a 2009 TL that I enjoy working on. This really taught me a lot more about the engine in my car and helped a lot with knowing just what I'm working with!
I'll take port injection over direct injection ANYday. It might be less efficient, but since the injectors are spraying over the valves, you won't have worry about that carbon buildup that GDI engines have.
Different but the same. My 02 Odyssey I bought in 08. Now has just over 340,000 miles. Today pulled the pan to do a oil pump, while doing the timing set. I've never been in this engine, only timing stuff and one set of valve cover gaskets. Not a single bit of sludge, or any other materal on the pan. The only oil and filter I have ever ran are Walmart Supertech synthetic. Lets not talk about two trans I've put in it though. With 6000 mile oil changes it uses about .5 a quart. I baby it. I make'm last.
At first when you look at the engine its seems crazy. But I actually worked on my Jv6 engine and everything he says makes total sense. I ended up putting back my engine with easy. It did take alot of youtube watching but I was able to fix my engine after half my valves bent. A word of advice, if you are not a do it yourself, its cheaper to have a mechanic work on it. It takes alot of time to learn, to buy the right tools, and to disensemble and assemble.
I also think these motors would heavily benefit from a catch can pcv system overly frequent oil changes with premium detergent oil has seemed to help with the carbon too
Cams definitely contributed to the tick. Did one one with a tick complaint and replace the cam and lifters. Tick gone motor ran like a top. Didn’t stop the oil consumption tho. Good thing a warranty company paid the tab
Awesome video. Funny that I’m looked at weird at times because I let my car warm up (‘12 CU2) before I drive. I do it to ensure that everything warms up effectively before I head out.
Very interesting video guys, man these modern(ish) engines are so complex with all those parts and so much to go wrong, when I was into rebuilding engines they were so simple anyone could do it and I'm talking about the 80's and the old Ford Pinto engines, I don't know if you folks had them across the pond but they were in most fords back then, they were very reliable and also very tuneable 👍 John UK.
This is most likely do to a bad owner or owners. These engines must have premium fuel not regular. Yes itll run on regular but itll make your engine look like this one. Also not changing the oil and filters on time. They probley never even done the timing or adjust the valves. My fiance has an 08 acura mdx 3.7l and it runs like the day it ran off the line bc it was taken care of. Synthetic oil, doing timing kit jobs, plugs etc. The whole nine yards. This is why most cars go out is bc of the owner not wanting to spend the money on maintenance or just not mechanicaly inclined . Hers also has 240k miles and gets the same fuel mileage it did in 08. I work at the Honda anna engine plant in Anna Ohio and I've worked in engine rebuild department since day one and these are honestly great engines
No, that's just not true. 3.7s all will eventually consume oil at some point. I replaced my oil religiously every 3K, and used nothing but shell and BP's top tier 93 octane. Still started burning oil. Acura has had to replace many 3.7 out of warranty cause of this issue. There's also an ongoing lawsuit. And if that wasn't enough, Acura released new designs for pistons and rings so yes they admitted it was a design flaw on their part.
@@supersabrosinho yes you're right. The setup for the pistons and rings was wack. They used lighter weight oil rings which have been changed since then and you can change to resolve it. But they fail mostly bc of how they're driven and taken care of. But this video wasn't the case. I've built more engines than all your local shops put together. This video is a case of bad oil and mostly using regular gas, hence the yellow. Oil would make it dark gas would make it yellow. They do have these issues im not saying they don't but this was caused by the owners is what I'm saying. Not that the setup was wack. I've owned 3 that made it passed 500k miles. They do have issues tho so you're right but I also am on what I said. We're both right on what we said but again in this video it was caused by owners. Also just because yours or others messed up doesn't mean they way they was driven or taken care of didnt play a role. I have the stock pistons and rings from 08. They used a lighter weight but now they use a heavier duty which is a darker ring which they use in hotter climates. Honda fault and owner fault. Still amazing engines if ran right. We build thousands of engines a day at the honda anna engine plant in ohio. I've worked here 9 years, and I've re-worked a lot of those due to line workers or robots. I know all honda engines like the back of my hand ✋ so in honesty I just know what messes them up or their flaws. Which typically is owners. They think they just run. Some oil here and there and some plugs etc. No it's like a baby you have yo be on top of everything. You don't just buy it for 33k you put thousands into it also. They all nickle and dime you at some point. Yours probably messed up due to the last owner. Yes it can still mess up even of brand new. All cars can bc workers do mess up. It's also the oil holes in the conrods. Trust this, it was bad gas and oil in this video not the engine but yes they fuck up bc of old design but can be prevented. And at the point of those rings it would have misfired b4 the bearings went out unless it got ran on low oil often bc of not checking it, again thinking it just runs. It could burn, leak, use oil for many reasons. Engines are science which we at Honda take pride in which is why we're a popular car. A lot of people think they know about cars and problem due but theirs always that guy that knows more and usually he's the one who specifically works on just that brand for the most psrt. There all really similar, every engine. Also I forgot to mention. Bc the fact we use pando to seal most stuff this engine tends to leak near the VT sylonoid fucking things up to but that's closer to 150k miles
The closest I've seen to such mastery of (dis) assembly other than this is a watchmaker video I once saw on youtube of a guy taking apart a complex automatic movement. Great video, very informative and I only wish I had John's skillset. Now what did you do with that engine??? Where's the video of this engine being rebuilt??? That would make a great follow up!
I had a j32 in my 08 TL that had severe rod knock. I was meticulous with maintenance and still baffled on how it happened.... Ended up replacing it with a junkyard motor and 40,000 mi later Same thing happened to that motor. Got rid of the car but I do miss it
These J37a1 engines are notorious for having bad piston rings, which will later in the life of the vehicle, after around 120k to start clogging the piston rings and push oil to be burnt. Honda/Acura extended the warranty to 8yrs vs 6yrs and up to 125k instead of 70k, which ever came first. I own a 2013 MDX with this mess (My 2006 MdX has 210k and doesnt run as bad as my 2013 with 185k !) I have been looking for a J37 for my 2013 with lesser miles...over 3k and everything has 140k or more. I can't g find a J37 with less than 100k or 90k. At this point, I think I will proceed with an engine rebuild. Great video ! Thank you,
My 2013 TL 3.7l has 62K miles @ almost 11 years old now. You got your money's worth based on mileage.. If you didn't rebuild this engine I hope you spent another 40-50k on a comparable newer vehicle. Boo Hoo for you!
I actually had the excessive oil consumption issue (burning 1 quart every 1000 miles) with my 13 TL shawd 3.7 j37a4, 6spd. Didnt do the recall on it to get the piston rings changed. And it was too late for me since mileage and age was past the extended warranty for the tsb. So I went out, raced revved it on the highway 4-5 time. And problem solved, the heat and high revs broke loose the carbon build up, and after that, no more oil consumption. You just have to race it a few times a month to clean the engine of the carbon build up on the piston rings.
Great job on the video. No matter what keep up the great work I learn a lot by watching your videos. One day when it’s time to work on my own car I’ll for sure use some of your videos as references 😅
I’m an engine builder and the J Series engine are nice to work on because of how modular the block is. Acura and Honda do a nice job on the overall engineering of this engine. But like any mass produced vehicle, they too skimp out on quality materials, like wrist pin bearing, o-rings. I have a 2017 TLX and have some plans to rebuild and upgrade the rotating assembly as well as a power adder. Enjoyed watching the video.
Very interesting viewing. In the UK 🇬🇧 we don’t have any J35 - J37 equipped cars. It’s a shame as Honda seem to be sending us very dull powertrains these days, probably as a result of strict emissions regulations?
Indeed it has to do with European regulations, J37 engine is a gas guzzler. I own a Acura MDX 2011 and best mileage on highway is about 20mpg, in the city 14mpg, but when you push down the gas pedal is a blast to drive! Never mind the SH-AWD, legendary power and prowess on inclement weather and getting you out of trouble in snow. Awesome engine but does require maintenance. My engine is now due for new water pump, belts and tuneup.. but my MDX is a keeper!
I have a 2000 Honda Accord v6 automatic. Put some Acura engine parts on the intake and I actually make terrible gas mileage. I get around 24-30mpg (30 usually highway). I have a little obd2 computer thingy
The engines meet California CARB regulations, stricter than Federal US restrictions. Taking into account J35 was introduced before 2000’s, and Dodge/Ford are still able to sell their giant engine models, kind of doubt it’s emissions related. More market “research”, same way barely any cars are offered in diesel and estates are often only offered with lowest trim packages in the US. It’s probably more Honda Japan choosing to make Type R’s available in Europe to fill the performance category. Meanwhile in the US there we’re several models designed and built here. Acura TL/Accord for example two common V6 cars. They are a full size up from the Euro Accord would which here is the Acura version of a Civic. But the USDM market requires more cars since Honda/Acura split the entire Honda product line.
I have a '09 TL SH-AWD with the J37. Unfortunately i think i'm having this exact same issue. There's a lot of valve train noise especially when the engine is cold and i've researched it. Most of the time it's the cams :(
Excellent video! I have a dumb question but why stop now. I have a very faint knocking noise under load (only) and the Crankshaft has end play that is out of tolerance. My understanding is the Crankshaft Thrust bearings might be the culprit. Before I do a complete teardown, I was hoping I could just replace those bearings with the engine in the car by accessing them through the oil pan and removing crankshaft cap #3. I recognize this is not the ideal fix, but figured it was worth a shot and would appreciate your insight as to if this is even possible. 🙂 Thank you!
Excellent video, our 2011 MDX had terrible oil burning issues but ran exceptionally well otherwise. We bought it at the 100k mike mark so who knows how it was cared for prior. Between the oil use and terrible gas mileage (16mpg) we traded it for a 2016 MDX that gets 25mpg.
Sadly, the MDXs and the majority of all V6 engines are extremely well known for burning oil. It is considered normal for them to burn 1L every 1k miles.
These engines have crazy valve clearances also. The added mechanism for VTEC on exhaust throws them out of spec in 30k. Almost not one does the valve adjustment on these engines.
I got a 2012 3.5L TL but have been tempted to invest in swapping it with a 3.7L and making necessary changes to the engine bay needed. Any other tips if I go forth with this?
Amazing video, Acura/ Honda should’ve made these engines better since they have been using the j series for a very long time and discovered the issues with the cams and the pistons. If i wanna fix both issues in the dealership it would cost me around $6-8k Canadian
Almost wonder if this is a recall type situation but the volume was just not high enough to make it really obvious that it needed a recall. I've seen people with a very similar ticking noise as mine (YT videos) who also had the exact same issue on the cams, similar wear pattern it looks like as well. I suspect the root cause is some minor engineering error/lack of optimization. Hard to know. I will probably just keep on trucking unless the noise gets worse, its not terribly loud. 2013 acura TL SH-AWD same 3.7 liter motor manual trans.
Thanks for the video. I was wondering if you might help me identify a bolt? At exactly 16:45 in your vid, there is a bolt not yet removed, it's above the oil pan, behind where the oil filter mount was located. Mine may have a drip at that bolt. Also, I think mine is headless, and has a female hex. Any help is very much appreciated. I bought the car used and don't know all the history. Thanks.
Was interesting to watch disassembly and explanation! I wonder what was that knocking noise you mentioned in the video. Is there a way you can point to a video/audio of the similar noise?
Had, have one. Piston failure number 4 low oil. Consumption problems. Found out the hard way. No low oil indicator except engine failure. Also engine overheats at incline in hot weather.
I have a 2012 TL SHAWD with 160k and have religiously had oil changes (synthetic) always run 93 mobile gas in it…I bought the car in 2014 with 12k on it..car ran awesome until at 100k it developed a ticking noise in the top end. Took it to my mechanic he recommended the timing belt be changed which is recommended also that they would diagnose ticking noise.Ended up being the primary cam lobes we’re deteriorating. Burns about a quart of oil every 1k miles. Had mech do the timing belt and they showed me where the lobes were boogered up. Had the motor flushed and oil changed of course. Ticking noise is still there. Car is in excellent shape and super fun to drive but the slight ticking pisses me off. So I guess my question is should I just get the cams replaced or should I just go for a complete rebuild.
What oil are you using 0W-20? If you are I would suggest going to 5W-20 it will put a thicker film on the cam lobe to help it not deteriorate as fast until u figure out the route to take on fixing the issue
@@mikeyeyes7 not sure what weight they are putting in but I will find out and start using 5w 20 if they haven’t, but what I have been doing is after about 1500 miles and it burns about a quart I put Lucas high mileage oil stabilizer(stuffs like syrup)in and it quiets up somewhat but the slight ticking is still there.. It’s a great car(super clean)and I take very good care of it(son works at Ziebart) and really don’t wanna let it go cause it’s payed off and don’t wanna car payment..Like you said I just have to deal with it. I’m definitely leaning towards a complete rebuild. I’ve seen other videos where the same problem has occurred and literally the same primary lobe that deteriorated. Thank you for replying I really appreciate it…
@@shawno9267 no problem at all I’m sure there putting 0W-20 I believe starting 2012 is when they went to 0w-20 I have a 14 TL and on my oil cap it says 0W-20 Acura switched over to 0W-20 to help with gas mileage & cold starts since it’s thinner in the cold winter mornings Our cars were built to be used with 5W 20 I still believe & others it’s too thin for our cars that’s why I believe a lot of these Cams are getting chewed up Even if they are putting 0w-20 in your car it’s perfectly safe to go to with 5W-20 with no issues or problems
@@shawno9267 The 3.7 in the AWD TL is known for oil burning due to the piston ring design. They have updated piston and rings that solve the oil burning. I'd get the pistons/rings replaced with the updated ones and also have the camshafts and rocker arms replaced. That will solve all of your engine noises and oil burning.
I also always tell people don't do ten thousand Mile oil changes on any car let alone any of the newer cars do the oil change the old-school service interval way.
This channel has really great music. I have a dedicated Spotify playlist of the episode songs that I play when I'm cruising. Hands down, best Honda content and channel available. Love you guys. 🔰💯👌🏻
@N Diesal So what I do is use the app Shazam to hear the music while I'm playing the video on UA-cam and it identifies it for me. Then I go to Spotify to look it up, add it to my playlist and I'm set. It works really well.
Notorious failing of this engine it was because the improper use of the engine, low octane gas and late oil change intervals seeing the carbonized oil rings. To summarize this the quality and construction of this engine doesn't appear to be cheap at all.
Most people should know, high octane IS a requirement for the J35-J37 engines and it certainly would benefit from synthetic oil. I can attest to no burning oil and smooth Use if my engine on my 2011 MDX with 100k miles. Although I getting ready for the water pump, belts and tune up
@@danielmelendez9943 well it might start burning oil soon after 100k but you’re lucky. My 11 MDX always had synthetic oil changes done every 3k. Burns about 1.2 qts every 1k miles
@@JulianRangel13 i took it to the dealership and i had it checked and i was totally lucky..i hope i can do another 50 to 60k miles with minimal maintenance b4 trading in
I used to be "into" Honda's pretty heavy back in the 70's-90's, and when kids started coming I slowed way down. But now kinda looking back at maybe swapping in a 3.7 into my IS300, and really piss off the kids.. It would be nice to have you give all the dimensions since you said that they are a sought after engine to swap. I know Bill Hincher already makes a GM trans adapter. So are there any changes in the bell housing mounting? Thanks.
Wow this is a great video!!! I have an issue there is low compression in 5 cylinders and no compression in cylinder 4. The SUV 3.7 mdx won't turn over when I try to start it. It blew out on the road. Also, I am pretty sure there are warped cylinder heads. All belts, starter, pumps, and alternator components are in tack. I don't know if the camshaft is damaged, but if the cylinder heads and gaskets were to be replaced without removing pistons can this be a cost-effective solution? I was also told by another mechanic that there needs to be a leak down test to see where it blew. I am getting so many different issues and no solutions. If all cylinders have low or not compression does that automatically mean needing a replaced engine? Any thoughts will be greatly appreciated!! TY.
Hello sir do you know the torque specs for camcap bolts?? Can't seem to find it anywhere on the internet for 2010 plus mdx.. if you can reply i would greatly appreciated it.. doing a valve job BTW thanks
Where’s the camshaft position sensor. I do have a drop in idling from 700rpm to 550rpm then it comes back up especially when I switch to sport mode. Any fix?
Acura Honda have recall on MDX knocking now with camshaft badly milled causes rod knock . 3.5 engine. That carbon build up I’d say had more to do with cam failure on that lobe. Lined up with those valves on that piston .
Thank you for the video. From it and what I've seen on several similar videos, also combined with from my own experience, the right-hand side head (front one, farther from the firewall) is always dirtier than the other one. This engine is pretty clean here, but just compare the valve covers: one of them is pretty dirty. Why does it happen? I this a Honda J-series design flaw? If one googles, one can find many complaints on the knocking sound of a J-series engine (other than the one due to a dead t-belt tensioner). Mine also does this, just like a diesel, on Acura MDX 2004 with 220k km. I believe the heads experience oil starving. BTW, I didn't see the sludge difference in the heads on 1MZ-FE in my Toyota Avalon, and with 300k km on it the engine just whispers.
This is because only the valve cover closer to the front of the vehicle has the PCV Valve. Only one of the heads is doing the dirty work, venting all the grime and soot that inherently comes from PCV. With mileage, age and poorly followed oil change intervals, only the front valve cover builds up all that grime hence the difference in colour. If you use high quality synthetic oils + regular oil change intervals it's really not an issue of concern.
@@joesepherion319 The proposed explanation doesn't work for 1MZFE (didn't have experience with other Toyota V6) - it also has only one PCV valve. I've yet to see an equally clean or equally dirty valve covers on a J-series engine.
Good video guys. I wonder, how many miles on this engine?. My 06 tl has 236.000 on it and running like new. I don’t abuse it though. Good tip on using higher octane fuel. How can I clean the piston carbon from my engine without taking out the heads?.
Your generation tl doesn't have issues like this unless you really abuse maintenance. Drive fast in my unprofessional opinion to prevent build up 😂. But seriously regular maintenance is important use OEM filters and the right oil.
Great video. I think this is one of the best motors Honda makes and will continue to own and run them. With regular maintenance and knowing what to pay attention to these can go for 200k plus even with a regular beating.
Totally false. The J37 sucks and was discontinued for a reason. No way you'll get 200k out of a modern day Acura without the torque converter or tranny going out first.

How much should a entire brand new engine cost from p2r performance cost
As to the cam failure I question the brand of oil that they were using. The coking of the oil rings I have seen before. I find the harder you wind up the engine the less coking you will see in the oil rings. I started working on Honda engines in the early 70's and continued till the first part of 2000.

You think these engine require premium fuel?
Would you consider using 5w30 in a VTEC engine?
The oil burn has been well documented. Was due to poor oil drainage piston design. New pistons are updated, once I rebuilt mine, no issues.
Yup, ring issue also related to piston design...also VCM issues but that's not the 3.7
Hey, anything I can do to my 01 mdx engine to make it more fuel efficient? And where did you get the updated piston?
Wonder how much to rebuild?
Where did you get the pistons from? Part number?
I ordered the pistons from “Acura parts warehouse” all one parts. All parts total came to about $2,100 give or take.
Now we wanna see you rebuild it with new parts :)
same, step by step :)
The J-series V6 is one of my favorite engines of all time. Such an elegant & beautiful design.
Couldn't agree more!
Dunno about elegant. The rollers are probably made by the same supplier, i.e., for Mopar.
Stinking 3.6L rockers...
cheers!
@@Scoot7827
Same rocker supplier as Mopar? Hahaahahah yeah right
That’s not Honda
@@Scoot7827 you are seriously delusional if you think HONDA would EVER and I mean EVER use a part off a fucking mopar lmao I swear fucking brain dead they don’t even use other companies transmissions and have always made their own shit and you think they’d use a part off a fucking glorified fiat

This video deserves more views! And some people doesn’t understand cheap gas on their performance engine will cost them more at the end, in this case, engine swap! Looking at those carbon built up almost made me cry!!
Thanks for the support
The carbon buildup is due to the piston rings being the wrong ones for this engine. Also, apparently system design had something to do with the oil burn and carbon buildup as well.
Virtually all of the 3.7 L engines are oil burners. This is well documented.
@@nickr5658 exactly this, besides, almost all V6 engines made by Honda since 2003 have extreme oil burning issues. There are thousands of complaints online regarding this, where every 1k miles driven, requires 1Qt of oil added. Not adding oil before the 5k means not having oil in the engine and completely destroying the engine, as these take 4.5QT.
As someone who's torndown my own j32 & j35 I will say you made this look super easy haha and these J series motors are beast.
You think these j37 Acura engines require premium fuel?
This is top tier content. Now I can replace my TLs pistons + rings. THANK YOU!!
Thanks for the support
Did you ever replace the piston rings? What would you rate the difficulty of doing so?
On a cold start of my 08 TL Type S, I won’t drive off until my NAV Display automatically turns off (maybe 30 seconds or so). Another technique I use on very cold starts is to watch my RPM drop from approx 1100 to 700 (idle RPM warm).
I do exactly same thing on my 07 TL type s. I wait for minimum 1k rpm drop. Usually 30 seconds or a min. And also synthetic oil. 350k miles on mine. Still running good
@@vectorracersame with my TL wait until 1k-7 RPM and go about my day. we care about our cars and it shows
I let my Acura drop to at least 1100 so it doesn’t jerk so hard when you put it in gear engines aren’t meant to have load put on them that early no matter what people say
Great video! Fun fact about the J37...it actually weighs less than the J35, because it uses aluminum cylinder liners.
Good to know
Under abuse ..wear far faster than ductile iron sleeves..J35A1
Excellent vid... thanks! I have four Honda/Acura vehicles with J35 V6 engines... oldest is 2013 Accord at 126K miles, and all run like new. 🤞 I have heard that the J37 Aluminum bores are the achilles heal of that engine as the miles add up... they score and burning oil is the usual failure mode. Surprised to see cam lobe wear... could that happen to any J series engine?
I’ve JUST done the timing belt on my 4th gen TL, knew EXACTLY the car when I saw the top lol.
Really cool to see the inner workings inside the engine, even MORE so glad I went with the FWD. absolutely LOVE the 4th gen TLs
Those motors are also notorious for scouring the cylinder bores due to the sleeve material and lack of proper oil changes also lack of proper octane fuel usage
I'm planning on rebuilding my SH-AWD TL in the future, this was incredibly helpful. Thank you!
Glad it helped!
FYI: The EGR T-pipe bolted down inside the intake manifold distributes the exhaust directly into the two intake plenums on either side. It does not route exhaust to the 6 holes in the top of the intake manifold. Instead those 6 holes and it's channel are the vacuum path for the PCV system. The blue PCV valve on the on the front valve cover regulates the vacuum while the chambers across the top of the valve cover separate oil from crankcase vapor. The vacuum hose on the passengers side then connects the valve cover to the 6 ports in the intake manifold. As soon as you removed the intake manifold cover I could tell the owner was not changing the oil on time. The channel with it's 6 ports should have been cleanest nearer that vacuum hose.
Yes cleaning up those, especially around 200,000 KM is a must
Y’all didn’t mention that these 3.7 have vtec on both intake and exhaust valves, when all single cam Honda engines only have vtec lift on the intake valves. If you ever have taken a vtec d series or J3.0-3.5 valve cover off you’d see it’s a lot more simple then the 3.7 engine. I was hoping y’all explained how the rocker arm assembly worked on that engine with a little more detail. It somehow locks both intake and exhaust rocker arms together on a bigger lobe.
Yeah, I’ve always wondered how Acura/Honda pulled this trick off. While other manufacturers put two cams per cylinder bank on their V6 engine designs for a version of dual VVT. Acura employs an elegant trick to achieve the same thing with a SOHC design.
No one has taken these engines apart & explained exactly how certain versions of the J-series work in detail. Many videos on this engine treat all J-series designs as the same… when in fact Honda/Acura have been improving their V6 engine non-stop since day one.
@@MrSamPhoenix I love vtec
@@joshuayammer1994 indeed!
Interesting point... I thought it looked a little different than the J35s I have seen in other videos.
I’ve always put premium in my Acura MDX 2004, it’s one year older than me 19 years old, been using it for that long too😂❤
Keep it up
I've also found out not all premium gas is the same..from now on I'll go directly to one of the oil/gas companies, rather than Cuz'n Jed's or some grocery store gas station. My engine used to make a ticking sound, then my dealer said change where you get your gas. I had already had a valve adjustment earlier in the year. No more ticking noise
That's not a 3.7 so why are you here???
@@thejake8099 use shell v power nitro
Nice video. Our Turbo 06 Accord J35A7 Swap makes 550whp on just 8psi. We (HalferLand Performance) specialize in everything Honda Jseries Performance related 🤙
We've found customers aren't changing their oil in proper intervals. Oil companies are advertising 10k miles which is WAYYYY too long. At 10k you'll get carbon build up and your cam lobes getting chewed up like this.
One of the best engine teardown video on UA-cam. Very interesting!
Thank you!!
Next time, When someone thinks I’m dumb for putting premium in my mdx, I’ll show them this video

Thanks for going to the effort to make this video. I subscribed after recently discovering your channel late last year. Even though I don't have a J37 myself, this is some fantastic content that is much appreciated.
Thanks so much for the support
I'm really glad I stumbled across this video as I own a 2009 TL that I enjoy working on. This really taught me a lot more about the engine in my car and helped a lot with knowing just what I'm working with!
Glad to hear it!
The oil burning only affects 3.7 TL
Outstanding video! High quality, highly informative and great commentary!! Thanks for posting for all of us Honda nuts!!!
I'm From Grandville Michigan. I've had Acurate engines rebuild my motors and they are top notch.
That’s great to know
I'll take port injection over direct injection ANYday. It might be less efficient, but since the injectors are spraying over the valves, you won't have worry about that carbon buildup that GDI engines have.
facts
That was a great video. Straight to the point but still very informative on how to properly diagnose a common issue with these engines.
Based on the carbon buildup on the pistons, this engine needed a good old-fashioned “Italian Tune-up”. Of course the cams were a different matter.
Finally someone does a 3.7 tear down
The intake manifold 😭💎👏🏾👏🏾. Need it !! thanks in advance 🙏🏾
I like this engine doctor! Great motor health analysis!
Wow, I can’t believe the amount of carbon on the pistons, I’d get pleasure in the cleaning process.

So satisfying to watch this teardown and not to mention the hypnotizing music
Thanks for watching!!!
Def a Ford/domestic guy but I love this channel. Keep up the great work and merry Christmas.
Thanks a ton!!
Different but the same. My 02 Odyssey I bought in 08. Now has just over 340,000 miles. Today pulled the pan to do a oil pump, while doing the timing set. I've never been in this engine, only timing stuff and one set of valve cover gaskets. Not a single bit of sludge, or any other materal on the pan. The only oil and filter I have ever ran are Walmart Supertech synthetic.
Lets not talk about two trans I've put in it though. With 6000 mile oil changes it uses about .5 a quart. I baby it. I make'm last.
At first when you look at the engine its seems crazy. But I actually worked on my Jv6 engine and everything he says makes total sense. I ended up putting back my engine with easy. It did take alot of youtube watching but I was able to fix my engine after half my valves bent. A word of advice, if you are not a do it yourself, its cheaper to have a mechanic work on it. It takes alot of time to learn, to buy the right tools, and to disensemble and assemble.
Thanks very much for your insight and totally agreed with you.
I also think these motors would heavily benefit from a catch can pcv system overly frequent oil changes with premium detergent oil has seemed to help with the carbon too
Agreed!
Cams definitely contributed to the tick. Did one one with a tick complaint and replace the cam and lifters. Tick gone motor ran like a top. Didn’t stop the oil consumption tho. Good thing a warranty company paid the tab
Awesome video. Funny that I’m looked at weird at times because I let my car warm up (‘12 CU2) before I drive. I do it to ensure that everything warms up effectively before I head out.
Good for you. That's a great practice. Wish we all do it.
@@ahcgarage prior owners didn’t really take care of it so I am babying her. I’m staying tuned for more content 🙌🙌🙌
Very interesting video guys, man these modern(ish) engines are so complex with all those parts and so much to go wrong, when I was into rebuilding engines they were so simple anyone could do it and I'm talking about the 80's and the old Ford Pinto engines, I don't know if you folks had them across the pond but they were in most fords back then, they were very reliable and also very tuneable 👍 John UK.
Thanks for watching as always John. Happy new year!!
This is most likely do to a bad owner or owners. These engines must have premium fuel not regular. Yes itll run on regular but itll make your engine look like this one. Also not changing the oil and filters on time. They probley never even done the timing or adjust the valves. My fiance has an 08 acura mdx 3.7l and it runs like the day it ran off the line bc it was taken care of. Synthetic oil, doing timing kit jobs, plugs etc. The whole nine yards. This is why most cars go out is bc of the owner not wanting to spend the money on maintenance or just not mechanicaly inclined . Hers also has 240k miles and gets the same fuel mileage it did in 08. I work at the Honda anna engine plant in Anna Ohio and I've worked in engine rebuild department since day one and these are honestly great engines
No, that's just not true. 3.7s all will eventually consume oil at some point. I replaced my oil religiously every 3K, and used nothing but shell and BP's top tier 93 octane. Still started burning oil. Acura has had to replace many 3.7 out of warranty cause of this issue. There's also an ongoing lawsuit. And if that wasn't enough, Acura released new designs for pistons and rings so yes they admitted it was a design flaw on their part.
@@supersabrosinho yes you're right. The setup for the pistons and rings was wack. They used lighter weight oil rings which have been changed since then and you can change to resolve it. But they fail mostly bc of how they're driven and taken care of. But this video wasn't the case. I've built more engines than all your local shops put together. This video is a case of bad oil and mostly using regular gas, hence the yellow. Oil would make it dark gas would make it yellow. They do have these issues im not saying they don't but this was caused by the owners is what I'm saying. Not that the setup was wack. I've owned 3 that made it passed 500k miles. They do have issues tho so you're right but I also am on what I said. We're both right on what we said but again in this video it was caused by owners. Also just because yours or others messed up doesn't mean they way they was driven or taken care of didnt play a role. I have the stock pistons and rings from 08. They used a lighter weight but now they use a heavier duty which is a darker ring which they use in hotter climates. Honda fault and owner fault. Still amazing engines if ran right. We build thousands of engines a day at the honda anna engine plant in ohio. I've worked here 9 years, and I've re-worked a lot of those due to line workers or robots. I know all honda engines like the back of my hand ✋ so in honesty I just know what messes them up or their flaws. Which typically is owners. They think they just run. Some oil here and there and some plugs etc. No it's like a baby you have yo be on top of everything. You don't just buy it for 33k you put thousands into it also. They all nickle and dime you at some point. Yours probably messed up due to the last owner. Yes it can still mess up even of brand new. All cars can bc workers do mess up. It's also the oil holes in the conrods. Trust this, it was bad gas and oil in this video not the engine but yes they fuck up bc of old design but can be prevented. And at the point of those rings it would have misfired b4 the bearings went out unless it got ran on low oil often bc of not checking it, again thinking it just runs. It could burn, leak, use oil for many reasons. Engines are science which we at Honda take pride in which is why we're a popular car. A lot of people think they know about cars and problem due but theirs always that guy that knows more and usually he's the one who specifically works on just that brand for the most psrt. There all really similar, every engine. Also I forgot to mention. Bc the fact we use pando to seal most stuff this engine tends to leak near the VT sylonoid fucking things up to but that's closer to 150k miles
My '03 Odyssey has a 6 cylinder 127k miles and doesn't burn a drop. Please explain why?
Damn. You made it look hella easy. Anyway thanks for the entire teardown video. It helps alot. 👍 👍
Cheers!!
The closest I've seen to such mastery of (dis) assembly other than this is a watchmaker video I once saw on youtube of a guy taking apart a complex automatic movement. Great video, very informative and I only wish I had John's skillset. Now what did you do with that engine??? Where's the video of this engine being rebuilt??? That would make a great follow up!
I had a j32 in my 08 TL that had severe rod knock. I was meticulous with maintenance and still baffled on how it happened.... Ended up replacing it with a junkyard motor and 40,000 mi later Same thing happened to that motor. Got rid of the car but I do miss it
These J37a1 engines are notorious for having bad piston rings, which will later in the life of the vehicle, after around 120k to start clogging the piston rings and push oil to be burnt. Honda/Acura extended the warranty to 8yrs vs 6yrs and up to 125k instead of 70k, which ever came first.
I own a 2013 MDX with this mess (My 2006 MdX has 210k and doesnt run as bad as my 2013 with 185k !)
I have been looking for a J37 for my 2013 with lesser miles...over 3k and everything has 140k or more. I can't g
find a J37 with less than 100k or 90k.
At this point, I think I will proceed with an engine rebuild. Great video ! Thank you,
Act like 185k miles is not a shit ton
My 2013 TL 3.7l has 62K miles @ almost 11 years old now. You got your money's worth based on mileage.. If you didn't rebuild this engine I hope you spent another 40-50k on a comparable newer vehicle. Boo Hoo for you!
I actually had the excessive oil consumption issue (burning 1 quart every 1000 miles) with my 13 TL shawd 3.7 j37a4, 6spd. Didnt do the recall on it to get the piston rings changed. And it was too late for me since mileage and age was past the extended warranty for the tsb. So I went out, raced revved it on the highway 4-5 time. And problem solved, the heat and high revs broke loose the carbon build up, and after that, no more oil consumption. You just have to race it a few times a month to clean the engine of the carbon build up on the piston rings.
I'm going to use this excuse the next time my wife complains I'm "hot rodding" around.
@@Chadman333seriously though, 09 MDX and we let her eat. Keeps the engine happy if after it’s warmed up you give it a little to wake it up.
Great job on the video. No matter what keep up the great work I learn a lot by watching your videos. One day when it’s time to work on my own car I’ll for sure use some of your videos as references 😅
Thanks so much for watching and support!!
Even with the worn cam lobes, I’d love to have seen a valve adjustment done and hear it run.
I’m an engine builder and the J Series engine are nice to work on because of how modular the block is. Acura and Honda do a nice job on the overall engineering of this engine. But like any mass produced vehicle, they too skimp out on quality materials, like wrist pin bearing, o-rings. I have a 2017 TLX and have some plans to rebuild and upgrade the rotating assembly as well as a power adder. Enjoyed watching the video.
Very interesting viewing.
In the UK 🇬🇧 we don’t have any J35 - J37 equipped cars. It’s a shame as Honda seem to be sending us very dull powertrains these days, probably as a result of strict emissions regulations?
Indeed it has to do with European regulations, J37 engine is a gas guzzler. I own a Acura MDX 2011 and best mileage on highway is about 20mpg, in the city 14mpg, but when you push down the gas pedal is a blast to drive! Never mind the SH-AWD, legendary power and prowess on inclement weather and getting you out of trouble in snow. Awesome engine but does require maintenance. My engine is now due for new water pump, belts and tuneup.. but my MDX is a keeper!
I have a 2000 Honda Accord v6 automatic. Put some Acura engine parts on the intake and I actually make terrible gas mileage. I get around 24-30mpg (30 usually highway). I have a little obd2 computer thingy
The engines meet California CARB regulations, stricter than Federal US restrictions.
Taking into account J35 was introduced before 2000’s, and Dodge/Ford are still able to sell their giant engine models, kind of doubt it’s emissions related. More market “research”, same way barely any cars are offered in diesel and estates are often only offered with lowest trim packages in the US.
It’s probably more Honda Japan choosing to make Type R’s available in Europe to fill the performance category. Meanwhile in the US there we’re several models designed and built here. Acura TL/Accord for example two common V6 cars. They are a full size up from the Euro Accord would which here is the Acura version of a Civic. But the USDM market requires more cars since Honda/Acura split the entire Honda product line.
My J35Y1 gets 32-33 mpg hwy.
I have a '09 TL SH-AWD with the J37. Unfortunately i think i'm having this exact same issue. There's a lot of valve train noise especially when the engine is cold and i've researched it. Most of the time it's the cams :(
Could also be time to change the timing belt. The tensioner can make noise when it's cold.
Excellent video! I have a dumb question but why stop now. I have a very faint knocking noise under load (only) and the Crankshaft has end play that is out of tolerance. My understanding is the Crankshaft Thrust bearings might be the culprit. Before I do a complete teardown, I was hoping I could just replace those bearings with the engine in the car by accessing them through the oil pan and removing crankshaft cap #3. I recognize this is not the ideal fix, but figured it was worth a shot and would appreciate your insight as to if this is even possible. 🙂
Thank you!
Excellent video, our 2011 MDX had terrible oil burning issues but ran exceptionally well otherwise. We bought it at the 100k mike mark so who knows how it was cared for prior. Between the oil use and terrible gas mileage (16mpg) we traded it for a 2016 MDX that gets 25mpg.
Sadly, the MDXs and the majority of all V6 engines are extremely well known for burning oil. It is considered normal for them to burn 1L every 1k miles.
My 2014 Acura TL rare manual still running strong . fun little car I love it 😎
Great!!!
These engines have crazy valve clearances also. The added mechanism for VTEC on exhaust throws them out of spec in 30k. Almost not one does the valve adjustment on these engines.
Useful video, thanks. Nice things to see also the condition of the bearing shells and cylinders surface.
Thanks very much for watching
I got a 2012 3.5L TL but have been tempted to invest in swapping it with a 3.7L and making necessary changes to the engine bay needed. Any other tips if I go forth with this?
Amazing video, Acura/ Honda should’ve made these engines better since they have been using the j series for a very long time and discovered the issues with the cams and the pistons. If i wanna fix both issues in the dealership it would cost me around $6-8k Canadian
Thanks for watching!!
Almost wonder if this is a recall type situation but the volume was just not high enough to make it really obvious that it needed a recall. I've seen people with a very similar ticking noise as mine (YT videos) who also had the exact same issue on the cams, similar wear pattern it looks like as well. I suspect the root cause is some minor engineering error/lack of optimization. Hard to know. I will probably just keep on trucking unless the noise gets worse, its not terribly loud. 2013 acura TL SH-AWD same 3.7 liter motor manual trans.
When picking up a used motor, what would u suggest needs to be done before it goes into the engine bay?
Thanks for the video. I was wondering if you might help me identify a bolt? At exactly 16:45 in your vid, there is a bolt not yet removed, it's above the oil pan, behind where the oil filter mount was located. Mine may have a drip at that bolt. Also, I think mine is headless, and has a female hex. Any help is very much appreciated. I bought the car used and don't know all the history. Thanks.
Was interesting to watch disassembly and explanation! I wonder what was that knocking noise you mentioned in the video. Is there a way you can point to a video/audio of the similar noise?
Unfortunately we don't have that audio clip
@@ahcgarage I see. What if I provide you with a couple of links with similar sound/noise from other Acuras, would you be able to compare?
Had, have one. Piston failure number 4 low oil. Consumption problems. Found out the hard way. No low oil indicator except engine failure. Also engine overheats at incline in hot weather.
I have a 2012 TL SHAWD with 160k and have religiously had oil changes (synthetic) always run 93 mobile gas in it…I bought the car in 2014 with 12k on it..car ran awesome until at 100k it developed a ticking noise in the top end. Took it to my mechanic he recommended the timing belt be changed which is recommended also that they would diagnose ticking noise.Ended up being the primary cam lobes we’re deteriorating. Burns about a quart of oil every 1k miles. Had mech do the timing belt and they showed me where the lobes were boogered up. Had the motor flushed and oil changed of course. Ticking noise is still there. Car is in excellent shape and super fun to drive but the slight ticking pisses me off. So I guess my question is should I just get the cams replaced or should I just go for a complete rebuild.
What oil are you using 0W-20? If you are I would suggest going to 5W-20 it will put a thicker film on the cam lobe to help it not deteriorate as fast until u figure out the route to take on fixing the issue
@@mikeyeyes7 not sure what weight they are putting in but I will find out and start using 5w 20 if they haven’t, but what I have been doing is after about 1500 miles and it burns about a quart I put Lucas high mileage oil stabilizer(stuffs like syrup)in and it quiets up somewhat but the slight ticking is still there.. It’s a great car(super clean)and I take very good care of it(son works at Ziebart) and really don’t wanna let it go cause it’s payed off and don’t wanna car payment..Like you said I just have to deal with it. I’m definitely leaning towards a complete rebuild. I’ve seen other videos where the same problem has occurred and literally the same primary lobe that deteriorated. Thank you for replying I really appreciate it…
@@shawno9267 no problem at all
I’m sure there putting 0W-20 I believe starting 2012 is when they went to 0w-20
I have a 14 TL and on my oil cap it says 0W-20
Acura switched over to 0W-20 to help with gas mileage & cold starts since it’s thinner in the cold winter mornings
Our cars were built to be used with 5W 20
I still believe & others it’s too thin for our cars that’s why I believe a lot of these Cams are getting chewed up
Even if they are putting 0w-20 in your car it’s perfectly safe to go to with 5W-20 with no issues or problems
@@mikeyeyes7 again thank you for your knowledge I really appreciate it…👍
@@shawno9267 The 3.7 in the AWD TL is known for oil burning due to the piston ring design. They have updated piston and rings that solve the oil burning. I'd get the pistons/rings replaced with the updated ones and also have the camshafts and rocker arms replaced. That will solve all of your engine noises and oil burning.
Nice engine I will like to know if I can swap one of does on a cg6 chassis ? That will be great
I need new pistons and rings would you recommend just buying a used engine or doing the work
Did you have a video of the 3.2l engine out of a TL?
I also always tell people don't do ten thousand Mile oil changes on any car let alone any of the newer cars do the oil change the old-school service interval way.
Agreed!!
Is there any benefit of putting the 3.7 manifold on the 3.2 engine? Like a 2007 j32a3 engine.

Notorious failing of this engine it was because the improper use of the engine, low octane gas and late oil change intervals seeing the carbonized oil rings. To summarize this the quality and construction of this engine doesn't appear to be cheap at all.
Some folks ignored the obvious and blamed others for their own failures.
Most people should know, high octane IS a requirement for the J35-J37 engines and it certainly would benefit from synthetic oil. I can attest to no burning oil and smooth Use if my engine on my 2011 MDX with 100k miles. Although I getting ready for the water pump, belts and tune up

But now kinda looking back at maybe swapping in a 3.7 into my IS300, and really piss off the kids..
It would be nice to have you give all the dimensions since you said that they are a sought after engine to swap. I know Bill Hincher already makes a GM trans adapter. So are there any changes in the bell housing mounting?

What’s the torques spec for the main cap ?
Such a pleasure to work on outside of the engine bay :). Not so much while in the car.
Do you happen to know the torque sequence for the lower intake manifolds? I only can find the answers of starting from the center to the outside.
Wow this is a great video!!! I have an issue there is low compression in 5 cylinders and no compression in cylinder 4. The SUV 3.7 mdx won't turn over when I try to start it. It blew out on the road. Also, I am pretty sure there are warped cylinder heads. All belts, starter, pumps, and alternator components are in tack. I don't know if the camshaft is damaged, but if the cylinder heads and gaskets were to be replaced without removing pistons can this be a cost-effective solution? I was also told by another mechanic that there needs to be a leak down test to see where it blew. I am getting so many different issues and no solutions. If all cylinders have low or not compression does that automatically mean needing a replaced engine? Any thoughts will be greatly appreciated!! TY.

I'm really lucky my J35Y1 in my '15 Accord has none of these issues. They got that engine dialed in by the 9th Gen Accords.
Cheers!!
Is the 3.5 in my 2008 TL type S worth rebuilding or should I get a swap ? It still runs good but is high mileage.
Hello sir do you know the torque specs for camcap bolts?? Can't seem to find it anywhere on the internet for 2010 plus mdx.. if you can reply i would greatly appreciated it.. doing a valve job BTW thanks
Excellent video , gotta do rod bearings on my j35, have a j32x2 and my j37 now excellent video
Good luck!
Where’s the camshaft position sensor. I do have a drop in idling from 700rpm to 550rpm then it comes back up especially when I switch to sport mode. Any fix?
Acura Honda have recall on MDX knocking now with camshaft badly milled causes rod knock . 3.5 engine. That carbon build up I’d say had more to do with cam failure on that lobe. Lined up with those valves on that piston .
I like how they use wishield washer fluid for coolant now on my 08 mdx ...double use ! 😂
Are you going to rebuild it? I'd love to see a video on rebuilding a J series motor
Not this engine, maybe a video in the near future
@@ahcgarage There isn't a good rebuild video out there so that would be awesome
Thank you for the video. From it and what I've seen on several similar videos, also combined with from my own experience, the right-hand side head (front one, farther from the firewall) is always dirtier than the other one. This engine is pretty clean here, but just compare the valve covers: one of them is pretty dirty. Why does it happen? I this a Honda J-series design flaw? If one googles, one can find many complaints on the knocking sound of a J-series engine (other than the one due to a dead t-belt tensioner). Mine also does this, just like a diesel, on Acura MDX 2004 with 220k km. I believe the heads experience oil starving. BTW, I didn't see the sludge difference in the heads on 1MZ-FE in my Toyota Avalon, and with 300k km on it the engine just whispers.
This is because only the valve cover closer to the front of the vehicle has the PCV Valve. Only one of the heads is doing the dirty work, venting all the grime and soot that inherently comes from PCV.
With mileage, age and poorly followed oil change intervals, only the front valve cover builds up all that grime hence the difference in colour.
If you use high quality synthetic oils + regular oil change intervals it's really not an issue of concern.
@@joesepherion319 The proposed explanation doesn't work for 1MZFE (didn't have experience with other Toyota V6) - it also has only one PCV valve. I've yet to see an equally clean or equally dirty valve covers on a J-series engine.
Good video guys. I wonder, how many miles on this engine?. My 06 tl has 236.000 on it and running like new. I don’t abuse it though. Good tip on using higher octane fuel.
How can I clean the piston carbon from my engine without taking out the heads?.
Your generation tl doesn't have issues like this unless you really abuse maintenance. Drive fast in my unprofessional opinion to prevent build up 😂. But seriously regular maintenance is important use OEM filters and the right oil.
@@chihirogustafson8557 thanks , I am super strict with maintenance, specially with oil changes.
150k miles on this engine. Cycle your rpm range at times can burn out some of the carbon build up
@@ahcgarage thanks Happy Hollidays.
Ther was a acura/honda recall for oil consumption.. it was fully coved by honda for j ser engine in my 2010 acura zdx.. could it be under warranty ??
Great video. I think this is one of the best motors Honda makes and will continue to own and run them. With regular maintenance and knowing what to pay attention to these can go for 200k plus even with a regular beating.
Very very true. Thanks for tuning in
Totally false. The J37 sucks and was discontinued for a reason. No way you'll get 200k out of a modern day Acura without the torque converter or tranny going out first.
@@marko6394 get a manual then lol
is this the same motor as the 2010 RL? I have the awd rl as well
Yes, same family
I've seen cam issues that look similar in a few k20a3 engines. I am wondering if its caused by some bad casting from the factory.
you're on the right track. It was a faulty hardening process from manufacturing. I work on 3.7s and see pitted cams like this often
