Spot on assessment. Blew the first head gasket at 12 months, and blew the replacement at 24 months on 19 si ethanol tuned. Then I used ARP head studs and cometic gasket and it's held for 31 months and counting. Car has had no other problems yet.
Sounds just about right.
@@BCautosolutions I currently drive a 2022 accord SE. Out of curiosity I decided to ask my Honda tech at my oil change appointment if he has seen 1.5T head gasket issues and he said they are bad engine. He does 1 to 2 head gasket replacement a week. He said it’s a good thing a got Honda care. It also said they are good cars but the head gasket problem is a weak area
@@dane940 he’s pretty much on the money about his assessment
@@BCautosolutions I think it is important I share this because some people still do not believe it is an issue. One to two a week is crazy. It is a shame because I really love my car. It is such a nice car. Honda really made a good looking car except the head gasket. I will be keeping since I got Honda care. After my Honda care expires, I will sell it and keep the money.
@@dane940 yeah it’s happening pretty wide spread from the amount of techs I talk to although some areas seem to not be having any at all, almost makes me wonder if the bucket is getting kicked down the road by techs or Mia diagnosing is going on. Honda care is 1000% worth it 👍🏻
Thank you for sharing. My 2018 Honda Accord with just 59k miles had its head gasket blown. The car has never been modified and I don't drive it hard. Had the misfire took it took Honda and they told me Cyl 4 failing test and that I needed a new set of fuel injectors not covered by warranty and Honda motor Corp would not help with the $1,593 repair bill. While I was waiting for the parts to be delivered my check engine light came on. I looked at the coolant it was empty, the oil looked weird. The dealer misdiagnosed my problem, it was a blown headgasket. This was my first Honda and it will be my last. I am out of the powertrain warranty by two months. Honda should be a shamed of themselves. To error is human to not take responsibility for the design flaw is shameful. I am going back to Toyota for good. Will vote with my dollars. Goodbye Honda!
How much did they want to do the head gasket?
Contact Honda Corporate. If your issue started when the car was under warranty, it has to be honored. You cannot be punished over a dealer's "misdiagnosis."
@@sarcasticundertones3513 the issue started 1 month after the 5 year warranty period. However the dealership felt bad that they had misdiagnosed the issue so they reached out to Honda Corp and were able to get them pick up the bill, thank God. I should have my car back this Friday. However the oil smelled like fuel so it has a dilution problem. I am going to sell the car and buy a Toyota.
@@robertpardo2034Since Honda Corp ended up picking up the bill he never gave me a quote. But an independent mechanic had quoted me $2,300 just for labor not counting the part nor if the head needed to be resurfaced. I think the entire bill would have been around $2,800 -$3,000. If I was going to keep the car I would have purchased the aftermarket bolts he was talking about in the video. It is a shame because I really like the car a lot but I just don't trust the engine and can't take the chance.
@@anthonyvelez7557that’s crazy, i’m having the same exact issue on my car but they said it’s fuel injectors… what can i get them to do to check if it’s head gasket
I love my 2.0L N/A civic. Not once have I regretted my choice over the 1.5t
It’s a solid engine!
You'll probably love this as well then. Someone was able to get an ecu adapter harness to work with something called MAXXECU mini. Which technically means know the k20c2 can technically be aftermarket turbocharged now. Though you would need to get a turbo kit.
Nice. Did you get the manual?
We did, K20C2 2020 Civic Sport Sedan 6 speed manual. ,, Fuel mileage is amazing with 93 octane gasoline, We only run 93 octane 1/4 of the time when loading it down to the max payload Used once in a While to burn carbon out, Just my opinion as a Diesel technician, I also run OW20 boosted Amsoil even though it's Not turbo charged. None factory upgrades Morimoto XB led headlights smoked and full led taillights only problem with those taillights is backup lights Suck, So going to add led backup lights once I find something that doesn't look Stupid, Thar who lower control arm thing was What I have seen on FK8 Civics so no, The sport had steel arms just like the one that snapped off, I hate to see what else got bent up on that White Car You showed on a Short Video, So I did an oil change on Our 2020 sport today at 40,000 miles had to correct a few Mistakes I bad with this Post Yesterday🧐 😁.
@@loranger6447 sadly not. My girlfriend dislikes driving manual transmission, so I got a CVT
Here in Saskatchewan, i have rarely seen headgasket failures. We do have however extreme cases of the fuel/oil mixing problems. The super cold weather then the blistering hot summers, combined with 10k KM service intervals. Ususally in the super cold (-35° - -40°C) is when we see this. Doing an oil change on a hot 1.5l in the winter months is similar to being on Splash mountain. Lots of engines failing due to oil filters coming apart. (Similar to the excessive camshaft noise warranty extension.)
Keep up the good work! Love the videos - always cool to see what other honda techs are experiencing!
Amazing how the weather can play a huge toll on different types of failures on same type of engine. Appreciate your input 👍🏻
I would do oil change every 8k km and myself I’m from the Maritimes.
very informative, in brief
1. design problem
2. weak head bolts
3. knock or detonation
can cause issues
Yes, also not tipping off coolant accordingly
"In brief":
1. Too many consumer expectations of HP from tiny turbo engines. Car makers need to quit building them and tell consumers they are s%it out of luck and build reasonable normally aspirated engines again.
2: 10,000 mile oil changes are unrealistic. 3,000 to 5,000 miles.
3. The EPA needs to lighten the F up. Gasoline engines are as clean as they are ever going to get without MAJOR sacrifices in reliability. Just stop. Let us have reliable gas engines again.
Dear God i hope the 2024 has had some uogrades . I just got an lx , i really hope🥹🥹🥹
I have an '18 SI which has 73k which is stock and I have been very happy with the performance and mileage with zero issues whatsoever. That being said, I would recommend buyers look at the 2.0 NA engine with a manual versus the 1.5T if your looking for long-term reliability.
Yep. My dad has been looking into new Civics and I recommended to NA version sport touring. And you can still get a 6 speed standard trans with a 2.0 believe it or not even if it's not an SI. I think that started again this year.
@@intraterrestrial69 wise choice! port injection engine with honda manual.
What he said!!
@@zkmoonea It’s certainly not port injection.
@@intraterrestrial69 you are right, its 2.0 DI
I have a 2023 Honda Civic Si. My L15CA has been getting 2000 mile oil changes from the dealership and is fed 92 octane from Chevron in WA. the vehicle has 6,700 something miles when I last glanced at the odometer. I am aware my car is still young but thanks to videos like yours, I am keeping on my toes. I do drive the car hard because despite the downfall of this CA engine. It brings a smile to my face and I came from a 2018 Honda Civic LX with the K20C2 and a 6 speed manual. That car also made me smile but the Si does a better job at it!
Hey man I hear ya, cars are meant to be driven. Your doing all you can do, if it fails it wasn’t due to lack of you trying to maintain and do the right thing. No reason you shouldn’t be able to enjoy the full powerband of fun. Thanks for sharing your honest experience.
Consider changing the oil at evert gas’s fill up.
@@georgeburns7251lol
You can go farther without oil changes simply because they use full synthetic oil my dealership said every 5k on a 14 accord. At 2k the oil life on mine is at 80 percent. To each is own for sure but should save you some money best of luck.
Cheaper just to buy a new engine than all that oil lol
Thank you for the post . I been waiting for this video for a while . I been using premium since I got my CPO 1.5T Accord . I been getting more gas mileage going premium .
Awesome, best of luck with it 🙌
I love this guys channel and everything he is addressing is very logical and fact based. I just wonder if he's going to get fired someday for shining a light on the poor engineering of the 1.5t 🤔 Seems like they could've just used better head studs. WTH?
Just stating what I’m seeing. Aftermarket head studs from factory will never be a thing. Thanks for watching
If my memory serves me right, the eco boost (ford) had a similar design and same head gasket failures, which they have now changed the manufacturing and instead have a small drilled hole instead of the groove. As to why Honda went this route is beyond me. They aren’t known to cut corners and as such would think they would spend the extra to negate head gasket failures.
Yup your spot on on your whole assessment.
I can’t believe Honda is having an engine concern. The company has been so thorough with their vehicles!🤷♂️ Thanks for answering my question on how to prevent!👍
Yeah I know pretty hard to believe. Sad times
Thank you for talking about in details about this issue.
Thanks for watching
We’ve seen this a few times also (San Antonio, TX) but not too often. Appreciate the input and actually makes a lot of sense. Will be curious to see if Honda comes out with a S.B. on them and how bad we’ll get plugged in the back side on the labor they’re willing to pay.
If and when that happens, I can only imagine how much the tech will get the short end of the stick.
how bad we’ll get plugged in the back side on the labor they’re willing to pay (c)
amen, bro
Ive been putting high octane for a while people said theres no benefits but im glad you give a legit one
People think no extra power means no benefits, what they fail to realize is a properly running non detonating engine is what they should be focusing on.
Finally been waiting for this video
Thanks 🙏
Thanks for watching
Get one of these every week it seems like. Agreed on the groove being a factor and how inconsistent the head bolts torque down. Good video. 👍
Thank you! And stay busy 🙌
Ford had the same issues with the 1.5 1.6 and 2.0 EcoBoost engines. Ford ended up with a new block design w/o these grooves also because of a much thicker material between the cylinders.
Yep, I’ve heard that a few times already. Thanks for sharing 👍🏻
This design appears to have similar design faults. As he stated, a problem by design.
I have a ‘21 Accord Touring 2.0T with 21k miles on it currently. After watching one of your videos, I switched from using 87 octane to top tier 93 octane about 6 months ago. Not sure I can tell any seat of the pants difference but it sure does run well. I love the 2.0T engine. I wouldn’t own the 1.5T but I understand why many people do.
Appreciate you sharing! Thanks
@@BCautosolutions Would you mind answering a simple maintenance question? At what mileage interval should I have the transmission serviced and coolant replaced on my 2.0T?
@@a32tl coolant 60k
Trans 30k
Thanks!@@BCautosolutions
The biggest difference is the fuel consumption , expect at least 50% more fuel usage with the 2.0 in other words 40mpg vs 27mpg
Have they fixed the issue? Looking at the civic sport touring or the integra. Also if it cannot run correctly on the minimum octane(whatever the manufacture says) without having reliability issues, thst kind of ruins the epa numbers
2018 CRV...traded it in for my 2024 Hybrid....had 138,000 on it....a tech at the Dealership I traded it on bought it before it hit the floor. I used mid grade and changed my oil at 5,000, also had a catch can on it from 2019.....she is still going strong.
Thanks for sharing and congrats on the new car 👍🏻
That’s good to hear. Hope we can get same result with my wife CRV.
I have a 2018 CRV and a 2020 Pilot. I am planning to sell the Pilot and keep the CRV but this issue with the gaskets (I just learned about it in this video) and the oil dilution issues on the 1.5L turbo have me worried. My question is, if honda is aware of all of these issues, why are they doubling down on installing the 1.5L on all CRVs and Civics? My understanding is that the LX trims still had the 2.0 L NA. Honda’s decision to expand use of the 1.5LT suggests that the failure rates are too low to be of concern to Honda or the failures are expected to occur long after the warranties are expired and at mileages so high that it would not appear to be unexpected. What do you think?
Could be isolated pockets of incidents would be my only assumption here. I only report what I personally see here at my dealer
First! Finally see you!
Mine 21 civic has 12K miles and I am going to put 93 octane from now.
Turn on Eco mode to lower the boost.
I think CRV and Accord have a much higher chance of getting Head gasket Leak!
👍🏻👍🏻
Thank you I think your assessment is spot on. I enjoyed your video and the information that you share with me. I will use it accordingly. Thank you again.
Thanks for watching and best of luck
Another great video. I myself and my best friend are unapologetically Honda Fan Boys as well.
Ride or die, I’ll keep buying Honda products as long as I’m alive. They have plenty of great products and occasionally a few misses like any other manufacture.
@@BCautosolutions: I couldn’t agree more. Every morning heading off to work, I’m proud to own a Honda Accord Touring. They got that car right. Occasionally they do misstep but compared to other competitors, they usually get it right most of the time.
@@JTreetop 💯
My wife has a 2020 CR-V 1.5T and we will absolutely start using Premium fuel all the time now. The last thing we need is a blown head gasket.
I also regularly change the oil with full synthetic and plan on doing the 1st CVT fluid change at 30k miles.
Awesome, I’m hoping for the best for you and your wife. 👍🏻
@@BCautosolutions Thanks I've been on top of maintenance but I just filled with Premium fuel for the 1st time at 30k miles. Hopefully damage hasn't already been done. We are honestly debating on just trading the CR-V for a Pilot.
@@bb2status crv hasn’t been as nearly affected as the accord although I’m all for upgrading to the pilot 💪🏼
Do it earlier and use AMS oil CVT Fluid. It helped dramatically, a lot smoother.
CVT? eugh, time for a new wife!
I took a used 2021 Accord Touring 2.0L turbo home for a long weekend test drive this morning. Before I saw your video I had decided to purchase the car next Tuesday, primarily due to the much more supportive 12 way power driver's seat than the 12 way in my 2020 Accord EX 1.5L turbo. OOPZ. Also the electro magnetic shocks help both ride comfort and handling. Overall despite being white (meh) with a basic blACK interior (ugh) the car has impressed me very favorably after a long day of driving despite the drop in mpg: 31-32 in the 2.0 vs the 36+ I get with the 1.5. Both cars have a bit over 31K miles.
My emphasis on the seat is due to a pinched nerve in my lower spine and a screwed up left hip replacement years ago. Both things leave me in pain-level varies-EVERY DAY 24/7. At any rate thanks for all the gr8 info on these cars and engines! :) DFO
Thanks for sharing
Thank you for the video. So because the accord has the most boost per 1.5T's, is the boost the issue, or the heat byproduct the issue from more boost? Does more PSI in the cylinder cause the head to lift or the heat causing it to lift/fail? Running only Shell 91 in CA for my 19' 1.5T Accord, should I be trying to keep the temperatures down as much as possible or the boost, which I guess go hand in hand. Could it be said the main goal is to keep the engine cylinder temp down as much as possible by babying the car, running high octane, and keeping coolant topped off? (Keeping coolant always topped off and use car as strict mpg daily car always being easy on her. She occasionally will see some boost for a few seconds if I need to pass on the freeway but that is about it ever).
Yeah it’s a combination of things. The more you can counter all those things the better. That’s about as much as you can do.
Babying the engine kinda defeats the purpose of having a high performance car though 😞
@@bobbyjohns1643 it's a commuter sedan, not a high performance car.
Recently had to replace head gasket on a 2017 Honda Civic sport w/ 138k. Purchased new, highway driven daily. Regular oil changes and did only run 87 octane fuel. Experienced vibrating and misfires on all cylinders, coolant was low. $3800 for dealer to replace head gasket and all new injectors. Very disappointed as I’ve had other vehicles with higher mileage and no issues. Going on about 8k miles since replacement. I’m hoping for a lot more miles out of this car. Good video as potential buyers need to be aware.
Appreciate your input.
Older cars are better NEW CARS ARE TRASH.
Jbh197 use premium fuel.
@@ericrotermund1004not necessarily, depending what you get
Are you also saying to go with 93 octane fuel for 1.5T?
2 videos I’d like to see, the 07-11 crv frame rust recall and the 2.4 start up rattle. The differences between the newer GDI engines with bad chain tensioner and the older engines with bad VTC actuators. Thanks!
I actually made a shirt yesterday of the Crv recall. The noises I’ll see if I can round up some parts and do a show and tell 👍🏻
Hmm my parents have an 08 crv in chicago area. How much/what does that frame recall cover?
@@neilquinnthe frame recall is an inspection of the rear trailing arm front mounting bolts. If the bolts are removed successfully then a bracket kit is installed to act as a catch for when the frame inevitably rots out and lets go. It’s just a safety catch. If the bolts fail to come out or just spin meaning the welded nut in the frame let go of the frame then further inspection is required with a borescope and Honda will be contacted, this will usually end in a vehicle buy back.
@@NitroxSkaterxChannel Any idea what buyback prices are like? Is it a good deal for consumer? My parents' 2008 AWD LX model with 120k miles KBB says is worth maybe 6-7k private party
I wonder about start up rattle too. Got a ‘16 accord 2.4 sport, change the oil every 3-4k miles, it’s never low on oil. But I continue to get obnoxious rattle on cold starts.
Thanks for the video. How many of these have you seen since? Has Honda been covering any of the costs? We have a 2018 CR-V with the 1.5T. Would you get rid of a car like that?
We do on average 2-4 a week. Most of them are in the accord. We do see some civics and Crv’s. At some point chances are, yours will need to be replaced. Honda only covers under normal warranty or extended warranty. If the owner has a good service history they can do a partial goodwill. (That depends on dealer, manager, district parts and service manager, and lastly Honda.)
Do you think a turbo blanket and lightweight flywheel could help with any of this? Those are going to be my nexr mods along with a stage 1 clutch
I have the 2023 Honda Accord EX (1.5T) and the owner's manual recommends 87+ octane or higher. I looked up the Acura Integra 1.5T and they recommend 91+ octane. Its the same engine! You're right premium fuel is the way to go.
This! Acura customers usually are easier to convince to use better fuel quality vs the average Honda owner.
Got the same car! You’ve sold me, 91+ it is.
@@BCautosolutionslol. In other words anything with a turbo engine for every brand has to use premium fuel and that’s how I look at it based on info you said on video
@@alvinsimba734 yep. Anything turbo 91 or better.
@Hondamobilemechanic what about 89?
They had the same problem in 2.0 eco boost from ford, they changed it for the maverick and escape ect to a closed deck ,and it seemed like its solved the problem.
💯
such good knowledge. 175K and pretty sure the gasket has been leaking for 15k. It was low on coolant 6 months ago, 2 months ago it started misfiring. After replacing injectors and coils, it stopped for 3 weeks then did it again. Borescope in cylinder 2 showed the leak. New gasket next week.
Sorry to hear! Sounds like it went pretty solid for a while tho.
Excellent failure analysis , just one or two more twists . Head bolts factor is not because what it seems to be as you played it out . But rather these bolts reacting to the abnormal change in thermal loads due to the software updates while using the wrong fuel and or oil 😮that these engines got 2018 onward to mitigate the fuel /oil dilution . That dilution could also influence the cylinder pressure . One way to shed some light on this issue is to check the live data under various loads while using high octane fuel vs low octane in term of timing and fuel / air ratios . Once you see timing still being pulled back when using high octane fuel you will know that there are fuel oil dilution . So frequent oil change and use the proper oil Are the keys As and using the wrong oil will lead to more LSPI events which is the root cause of excessive cylinder pressure variations .
🫡✅
Always keeping it 💯...Keep up the great work 💪
🙏🏻
@@BCautosolutionsReally appreciate these inputs from you buddy. quick question. my 18 accord ex-l is at 35k miles but its engine started sounding like old one at this mileage. Is that common? Nothing problem tho just the sound we get from car's engine when it ran too many miles. It all started when I put 4k miles in the previous month. Been taking your suggestions and switched to 93 octane tho. Please lmk your thoughts on this.
@@kesavravipati could be a bad bearing somewhere, best bet is take it to your local dealer or mechanic and have them pinpoint it
@@BCautosolutions gotcha thank you bud :)
@@kesavravipati I think you need to describe the sound better and where it is coming from.
Finally! Someone besides me knows the importance of putting a higher octane on import cars. Kudos to you bro, keep up the good work! I myself is also a Honda tech and believe me when I tell you that almost everyone at my work doesn’t know the difference of gas octanes and what they do for import engines.👍👍
People including techs have their heads up their behinds. Luckily a ton of the people watching this are looking for answers and se to get it so I’m happy about that!
Everywhere i look it says the 2.0t is fine on 87 unleaded, should i be using premium?
@@name4754 If you drive the car easy, 87 should be fine...but I still wouldn't use it. If you are hooning the car around, spooling it up constantly then you should be running the higher octane. The harder you beat the engine, the more precise you need to be in the power stroke and having 93 in there is going to allow your car's EMC to manage the situation properly.
good to know.. been using 87 on my 1.5t sport for almost a year now. I haven't had any issues with the car but I have noticed while I'm in traffic the car begins to idle a bit rough, the rpms start bouncing from 500 to like 800rpms. I'll definitely be using premium from now on
and I also do uber eats.. I've driven this car 20k miles in 8 months lol still perfect
Sticking with my 1.8l 94 ls integra. Best era for honda/toyota
True story
Stronger head studs at higher torque. The aluminum head will still want to expand at the same rate. Is there a chance the higher torque/stronger bolts will lead to crushing and eventual loss of clamping force? Would re-torquing the stock bolts as a preventative measure help?
ARP head studs will keep the head/block together for a lot longer and at higher power levels although there are other flaws with the engine. Re torque the oem bolts will do nothing in this case.
Ford had the same design coolant relief cut between the cylinders and was cracking the block. They had to redesign the coolant passage in the block and it fixed the coolant intrusion. Sounds like a redesign is in order!
🤐
How about end the turbo era now lol
@@ericrotermund1004 it will end with EV cars which is even worse lol
I am having a accord 2018 54000km filled up with basic gas twice….. i felt drop in initial pickup and engine sound increased …. And after i decided that never to fill up with cheap gas always filled up with mid or 2nd grade …. Always felt happy … engine sound smooth… and obviously got a good average aswell and after watching this video feeling proud that i m unintentionally using a good fuel on my car not have any issues so far
👏
Just finished a head gasket job on my 19 accord. It had 101k miles on it. Hoping it’ll last at least another 60k
Nice job 👏
Great video and very informative!
Thank you!
I have a random question to ask about a acura 1.5 ev model non turbo i believe. Its a 2013 with a overheat condtion, From what i can tell it overheats randomly. So for example itll be fine when in the shop at idle and getting it up to temp. Ill watch the scanner etc everything seems fine its flowing good etc. Then when i drive it itll start heating up on the engine side and ill see the motor start to overheat and then see no coolant make its way into the radiator. Now i thought maybe bad rad we just replaced, so we swapped it. That solved nothing, we swapped the t-stat twice etc, Pulled the pump and it was proven good. Even the belt not great with tensioner seems okay atm. Its not making any sense why its overheating except maybe a head gasket i suppose. One thing i found was a milky coolant in the intake chamber which was odd. Not sure if these have a intake manifold that shares a coolant passage that could cause this. But when i pressure test it, it doesnt seem to loose pressure. So im at a loss right now, gonna check the cylinders tomorrow, maybe do a leak down test.
I bought mine new 2021. Been using 93 octane. I had a 3rd gen TL before.
I do a 60 mile commute and average 40 mpg. I am 40,000 miles. Thank you for the advice.
Thanks for watching
the TL was a way better car
I agree.
Hopefully they would have resolved this issue in the new generation accords and civics , Hondas reputation could be on the line if these kind of issues persist. For example look at nissan they've been using the same crappy unreliable cvts for decades now and still haven't learned their lesson.
Only time will tell what happens here
Heavier car, boosted tiny motor, results can be anticipated. Manufacturer evidently didn’t bother to clamp the head accordingly, didn’t beef up the supporting systems (cooling). Run!
Lots of facts
I think I lucked out, I just got the 24 civic sport hatchback with 2.0 na and manual trans. One thing I noticed going from 6cyl GM products to 4cyl honda is that they are much slower, sometimes I have issues merging on the interstate even. I baby it though and am loving it so far. I drive about 50 miles to work one way and its interstate straight shot so only long trips. One thing I worry about is the eco mode, do you think using it over time will cause more engine wear, rather than not using it?
Yeah your missing out on some power but your going to get that long term reliability. Using eco mode won’t cause any extra wear.
I know Honda made some internal changes to the 1.5 starting in Model year 23. Crank ,oil pan , turbo have been re worked. I can tell at least in the CRV- Smoother quieter more refined. Do you think the HG issue will still exist?
Not sure tbh we will have to see but I believe head bolt and head gasket parts numbers cross over, I would have to look it up
@@BCautosolutions Do the injectors also still have the same part numbers?
Love the 2.4 in my Honda Accord Sport
Will Never get a turbocharged car. Oil Dilution and Head Gaskets prove me right again.
👏
Your Honda videos are excellent . We communicated last week on scan tools. I have purchased the launch Honda only version. Should arrive today. Now what year civics could be affected? I know my daughter just purchased I believe a 2022 civic. I’ll find out the model and inform her about the issue. Much appreciated. I’ve been a follower I believe sine your channel was created. I’m out here on Long Island. Thanks for sharing your Honda knowledge. Artie 👍
Thank you for making these vids and making people aware. All manufacturers make mistakes, just the unfortunate reality of production. its all about how they make it right to the peiple that buy em. You hear anything about the j30AC in the type S?
J30ac has been very solid, no engine failures that weren’t due to human error that I’m aware of.
this is because of one thing--government mandates
I still have a slight interest in a ‘23 Accord EX. I have also read that the fuel injectors going bad prematurely is a problem, too. Do you think bad fuel injectors and blown head gaskets are pretty much a given to eventually happen in the 1.5t engine?
Imo, yes. Even if it happens later on in the engines life at let’s say 150k (which is atleast a reasonable fail period), I believe most of them will eventually suffer from failed injectors and blown head gaskets.
My civic 1.5t has 170k and had never had any crazy problems. It also was one of the last model years assembled in Canada so that may have to do with it. Only problem I’ve had is a wire splitting on the turbo solenoid from engine vibrations but it was an easy splice and fix. I also replaced my injectors at 160k because it wasn’t a hard job. There was carbon build up but nothing crazy probably because I drive like I stole it. I change my oil every 5k and cut fluid every 30k.
@@landenk2659Cut fluid every 30k? What is that exactly. I have the 2019 accord 1.5L
Thanks for the insight! I have a 2018 1.5 sport w/ 61k miles.
Always on time with oil changes ( ~5k), 91 / premium fuel, always let it warm up and i dont drive that hard. Fuel cleaner in the tank every 5k as well.
In the last week, ive noticed the car cold starting rough ( shaking or misfire maybe?). At first i thought it was just due to weather since its been getting colder in NY. But then i checked and my coolant level is lower than it normally is ( usually around full but now its half way between min and max). The car drives fine afterwards. Even yesterday, it started normally.
I feel like i know the answer already but is the head gasket likely compromised already? I ask because I heard it could also be the spark plugs or fuel injectors as well.
Sounds like possibly injectors and/or head gasket unfortunately.
@@BCautosolutions It can be both? That’s truly unfortunate. Sucks to do everything to prevent this and it still happened. Can the gasket blow again after its replaced?
@@kylefrederick4269 yes it can be both and considering we at the dealer atleast replace with oem bolts and often times the already used ones the problem will only occur once again but even Sooner.
Sigh. Might just be best to trade it in before it gets even worse. Idk. Thanks for the insight and help though! Really appreciate it. 🙏🏿🙏🏿
@@kylefrederick4269 anytime and best of luck
I’ve got a high volume intake on my 1.5L engine, I care a lot more about the engine health then the cool sound it makes. Would you recommend going back to the stock one?
No, the intake is fine and won’t do any good or bad.
I live in California and I bought 2022 Honda accord sport, what would be your recommendations to try to avoid or minimize this problem .
-91 octane
-Keep an eye on coolant level in res and top off as needed
How difficult is it to remove and install the studs alone? Not the whole install but just the removal and torquing down the new ones. Id like to do it myself in the future but am worried about snapping one.
Should be a 2-3 hour job max.
Ford had the same issue with the 2.0 ecoboost with that same kind of groove. They removed that groove on the block no more head gs issues.
This!
Interesting information sad to hear this long time Honda fan have owned 6 my newest is a 2010 in the market but concerned so many bad designs since 2012
Yup. I hear ya
Does changing the oil or coolant more frequently help as well? Thank you.
Yes I’n other ways. I have a full maintenance recommendation vídeo going live on Wednesday 7pm eastern.
had cold start misfires, sputters, did head studs and so far so good! about 5 months after.
So head studs and kept same gasket?
Would love to know if you could respond @vongu2090

Hi,just came across your channelWatching from Trinidad in the Caribbean! .Owner of a 1999 Toyota Corolla and a 2002 Toyota Camry both still running extremely well enough.Quite a tall guy so was looking for to get a CRV 1.5 T to replace my Corolla run around as though solid much too small for me.Went to Honda dealer here and a customer is turning in his 1 year and something like of CRV with 16.000k on it as his wife works from home and she got company car now so they not using it.Apparently only used on weekend so much that the battery died and they had it replace.3years warranty left and serviced 2weeks ago.Test drove it yesterday and really like the comfort ,response and feel of the drive.Likely getting some money off.Would you advise it or is this sure to be a money pit with your mentioned issues? Keep up the good work! Thanks
It’s always a gamble with these imo. I would purchase Hondas extended warranty if available there.
Ford had a similar problem with their 1.5L as well. A small redesign of the block to remove that groove solved the problem.
Ding ding ding 👏
Does it make a difference how aggressive you drive? I know the turbo is 20psi, but if I'm rarely hitting over 2,500 rpms, would that in theory be less pressure in the cylinder against the gasket and bolts, compared to more spirited driving?
Absolutely makes a difference
The Ford tech mukaloco channel has a good explanation on the Ford turbos going from a closed deck in 2016 to open deck with the cross slots and now to a cross drilled design so the block gasket surface is continuous. Will Honda do the same 🤔
TBD….
On the K20C4, do the cams have to be pulled to swap the head bolts/studs?
I’d like your opinion on an idea for a fix, being I’m not that familiar with this engine or Hondas in general. I am guessing that it’s a water jacket under that slice between the cylinders, why couldn’t you go to where the water enters that canal on both sides drill and tap it and install a set screw to block the water passage then take a file and make sure that it is even with the deck?
Food for thought
Part of the reason I bought a '16 Accord was because I just knew Honda would be going turbo and ditching the trusty K24. They usually don't let common engine issues like this persist for too long, hopefully that's the case here because the L15 is gonna be around for a while.
Good call and agreed.
theyre going to get a bad reputation witht he oil dilution and HG issues- my 98 integra runs like a top just a regular 4 banger
I did the same as well. Got the 2017 cuz I didn't want to deal with any turbo headaches
It's back to the d and b series of the 90's. K series going back to premium.

I have a 1.5T and live in N.J.
The thing is I use my Civic for comuting 100 1 way!
So 200 miles a day direct injection and a turbo works for me.
I do my own oil changes and can say I do not smell much if any gas in my oil.
However in the begining I did smell gas in my oil but that was a few years ago.
My 1.5 T Civic ex has 140 miles and it's a 2020.
I do not see any indicarion of coolant in my oil or low coolant or oil levels, so far.
I do drive my car fast with 98% highway miles.
17 crv kept in meticulous condition using 91 octane . Head gasket at 50k. All the usual symptoms. Dealer said it was a bad radiator cap. Dealer bought the car back. We bought a Lexus. Problem solved.
Bad radiator cap 🤣.
Owned several Accords since 1996 including an 07 3.0Land 15 2.4L now. Your video has convinced me to avoid a new 1.5L Accord. Now I would only consider the 2.0L hybrid or buy a Camry. It seems clear Honda engineers have not figured out the 1.5T. Wonder if they ever will.
Your assessment is on point.
Lots of bad head gaskets on accord hybrids as well
@@LiquidSm0ke Perhaps but anecdotes don't show the prevalence of the 1.5L.
Do you think this is still an issue with 2024 civic models with the 1.5? Has Honda address any of this for cars just recently built? Im trying to decide between the 1.5 and the non turbo 2.0
The overall engine design is still the same. Get the 2.0 for maximum reliability
Hey man, another very informative vid. Have you considered the idea that the climate you live in may have a huge part in this specific problem being so prevalent? I work in south Texas and since working at Honda I haven’t seen a single problem with the heads on this motor. Could it be because people drive the cars super hard early in the morning before the car has fully warmed up? Lmk what you think
Hey man, yes that’s definitely a possibility. That’s pretty incredible that you haven’t had not 1 yet. I’m in contact with a decent amount of techs across the country and we are all generally seeing an uptick.
Are you from the RGV by chance?

I too am a Honda fan, just sold my s2k..had 2 of them. Also, I am a Porsche lover, so the head gasket story brings back a story about the very early Porsche 935, race car. 2.1 litre, very high boost making 850 hp and blowing head gaskets. The engine was staying together in 12 and 24 hr races but they had to fix the head gasket problem....so, until they could figure a better way out they actually welded the head to the engine case....expensive but winning* races was more important....
Thanks for sharing
@Hondamobilemechanic
Are there any info about these problems in EUDM models? In EU there are no Accords, but 2017-on Civics and 2018- Cr-vs are with 1.5 turbo
RON is between 95 and 100 on european petrol.
From what I have read in the comments here, these issues don’t seem to be affecting the euro market cars. Fuel quality and the fact they don’t have the accord only validate my points even more.
Would you be able to provide similar analysis of the L15 in the 11th gen Si? great video, thank you!
For sure, we know the bottom end is slightly better although I can go into a full video with more in depth details.
Wow just now seeing this. I'm at 65K on my 2018 Accord 1.5T CVT. My coolant level is full, been that way since new. I do regular oil changes with full Pennzoil Ultra Platinum synthetic...but have been running 87 octane since new. I'll switch to 93oct today LOL. It's my daily driver, I don't drive it like a ragged drag racer.
Nice job with the maintenance 👍🏻
I’ve been a Honda guy all my life. This is telling me I need to consider becoming a Toyota guy.
Gotta go what’s best for you 👍🏻
2018 Camry na 2.5 the best almost 70K
I have both, I’m leaning toward Toyota a little more but I wouldn’t buy anything outside of Honda or Toyota
@@hermanpeters549 73K now lol
Do you think Honda will extend they warranty on these? I run only 93 oct, get my oil changed at 5k miles, and use Seafoam injector cleaner every oil change. I still have 55K left on warranty. Not sure if I should trade it in shortly before it expires or not.
I’m not sure to be honest, I would make the call as you get closer to that mark, seems like you still have a few years to go 👍🏻
Good job, 80% of what we see are CRV's... Rough idle on cold start with no misfire DTC yet and low coolant reservoir are the indicators early on in our experience as well. Pressure test and a bore-scope and yup its leaking. Only seen one Accord and no Civics...... yet. We put new ones every time with warranty or customer, there is a spec to measure and reuse but they may be stretched a different lengths so new ones all the time.. Thanks for the heads up on aftermarket studs. Honda says they are failing and the fix is a new gasket, they sell thousands and the failure rate according to them in acceptable, I personally think they will come out with a check and re-torque like they did with the 1.6 back in the 90's, but by then its already leaking.
Appreciate the input, weird how you’re seeing Crv’s yet we are seeing majority accords. Where’s your location?
@@BCautosolutions Northern Ontario, Canada. Most of what we sell up here are CRV, then lots of civic and few Accords, that might be why. I think the temp extremes cause issues to. It can be -30c, people will remote start twice to get what little heat these things generate into them, then blast up the hiway. The coolant gap is not helping either I think it causes to much expansion and contraction in that area making the head and the block just grind away the black dealing material on the gasket. It’s funny how the fail Gen civics (01-05) failed the same way in the same spot and the gasket looked the exact same way and they were NA, did a ton of those.
@@MayhemCanuck yeah that makes sense for sure. appreciate you sharing!
My accord has this EXACT problem set
I started running 93 octane at 30,000 miles in my 21 accord sport. I was running it a some of the time before that but when we had $6.00 a gallon fuel I stopped. I check the oil and coolant once a week. I put a piece of tape on the coolant reservoir to keep an eye on the coolant. Also I never drive like I stole it and drive it like an old lady. The 1.5t is a good running engine with lots of power when it’s not broken.
I agree, it’s great on power and torque that makes it more interesting to drive them previously. Keep up with the fuel, coolant, and maintenance 👍🏻👍🏻
“The Federal Trade Commission recommends using regular gasoline for most standard cars and notes that: "In most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage, or run cleaner."
Higher octane to reduce detonation because of design flaw. Nothing to do with cleaner or faster
The power train worries aside, my fiancé's 2023 civic hatch already has annoying issues (warped brake rotors, side window rattle, TPMS lights that don't turn off, a sticky e-brake switch, hatch strut failure, sun visor just fell off, and paint chips. My 2021 Corolla hatch se 6spd hasn't had any problems. I think the crew who built her car partied the night before. 😢
That’s unfortunate,’sorry to hear. Has dealer handled all the repairs correctly?
@Hondamobilemechanic everything except the paint chips and TPMS light. They said, "Just drive it at 40 mph for 30 minutes, and the light should turn off." It did eventually, but it keeps happening. Luckily, the front brake rotors happened at 7k miles, so they were covered after resurfacing didn't work.
My 2017 Honda paint is coming right off down to the primer but first on plastic items like mirror and door knob. You must get documentation via a wrk order that states the issue. Don't even discuss it with the dumb advisor. Push it into technician to verify complaint.
check the settings in the infotainment. might have a like system or vehicle option. mine has a TPMS reset in there. dunno if they finally added in real TPMS sensors but the whole system is scuffed, was just using changes in how the wheel rotates to check
Keep seeing blocks with those cut outs. What is the initial purpose of those grooves. I can;t think of any benefit so near a sealing area.
Me neither, that’s a question for engineers 😅
I'm keeping my 16 accord sport 6mt for a lot longer than i thought I would. They can keep the turbo cvts.

The word 'phenomenal' is reserved for Honda's J series engine.
I personally own a 2003 Accord V6 equipped with the J30A4 engine, that is a phenomenal engine.
Hopefully I can buy the 2008 Accord V6 (J35Z2) in the future.
Anyway great video & explanation.
J series definitely up there are far as reliability with the exception of a few years that were really caused by horrible maintenance imo. Thanks for watching
Transmission wise on the v6...not so much.
@@LarrySolimandepends we have one with 340k on it. Doesn’t shift great anymore but still works
@@ericrotermund1004 I guess it really does depend. Ask anyone with a TL before an 07. I would bet it's 50/50. To anyone reading, USE oem fluids and install a transmission cooler.
Typical signs of a blown head gasket on any car not just Honda: Oil mixed with coolant, boiling coolant in the reservoir, milky colored oil, white thick smoke from tailpipe, constant coolant overfilled reservoir while radiator keeps getting empty. However, the best procedure to detect a blown head gasket is a block tester. I had a 1988 Honda Civic 1.5L . I replaced the gasket and problem solved. It is recommended to replace cylinder head bolts as they are called "stretch bolts..." How to prevent blown head gasket? Keep your coolant clean and perform a coolant service every 30,000 miles. After coolant service, make sure no air pockets are trapped in coolant system. Purge any air out of system using a spill free funnel. If not available, start engine and rev up to 2500 RPM until both coolant fans kick in while squeezing upper coolant hose, allowing bubbles to travel to the surface of the radiator opening .you will see the air bubbles popping out as you squeeze hose. Make sure your heating system is all the way to hot but not on as to allow coolant circulation through the heater core.
Have current 2024 CR-V.
Will be checking coolant and will consider switching to premium gas.
Still have a question, if you dont mind - how often should I change the oil, keeping in mind well known Oil Dilution problem on these turbos and fact that I live in Montreal with quite cold winters? Will 5k KM (not miles) will help with both problems - gasket and oil dilution?
Great and helpful video anyways - thank you!
Absolutely 5k km should reduce chances of a list of things going wrong.
@@BCautosolutions
Thanks,
did my first 5k km oil change (at Costco - crossing fingers). Now, considering doing oil changes myself if it'll be happenning during warm seasons.
Also switched to 91 gas (Costco doesn't have 89 or 93).
Years ago in Europe my first car was Hyundai Accent 1.5 CRDI (turbo diesel) and what I've noticed, which seems to be the case for 1.5T CR-V imho:
First - smaller, underpowered engines DO feel the difference between gas octane (cetane for diesels) number - more power via higher torque
Second - highway (only!) fuel consumption will go down, which will partially compencate the higher cost. Cause while city driving, especially on turbos, we over-accelerate (at least a bit) from EACH start, so we likely will burn any gain in power of higher octane fuel. But EVEN without reliability reasons higher octane fuel is "must have" for longer highway trips for smaller turbos. Didn't feel this gain on my 2018 Civic 2.0 SE though 😀
Third - Accent 1.5 CRDI was EXTREMELY sensitive for oil change intervals - after 7k km it was becoming sluggish and the further the worth. Keep in mind, 1.5 CRDI for Accent is a LOT of power - not in HP, but in Torque! I was literally polishing asphalt with tires. Really rarely smbd was leaving traffic lights before me. And still - 7k km and you really feel the difference. And for this "fridge" CR-V smaller turbo engine is barely enough by default. So, frequent oil changes and 91+ gas does make quite sense.
I would think the xj12 jag motor would have been a learning experience for the engineers but still manufactures are recreating the same issues.
Over and over, it’s like they don’t learn lol
Considered buying a new SI but with this issue plus the mark ups I ended up getting a used ES 350 I ran across at the Lexus dealership one day. Haven't regretted my decision, its not as fun but its way more comfortable and will last forever.
Appreciate your input 👍🏻
It would be great to have everything in one car, but you'd end up like me with a minivan, sedan, SUV, and a Miata.
@@bobbyjohns1643 atleast you have options for all sorts of events 👏
Thank you brother great info.
🙌
it seems to mainly effect the 2018 models from what i've read on forums. almost every single blown head gasket i've read about is from a 2018 model. so i'm wondering if they redesigned something to fix the issue.
They didn’t. I’ve done them on all years except 2022 which they just haven’t accumulated enough mileage yet.
History repeating itself (rash of head gasket failures).
Back in the 1980s (when aluminum heads with Iron blocks became common) there was another rash of head gaskets failures (Mopars, Mazdas, Cadillacs, Fords, VWs, diesels and more) but most people junked the cars since the typical life of cars was 100k miles, and to put an expensive repair on an 70k car was not worth it. (now the cause is turbos on little engines)
History always repeats itself
@@BCautosolutionsthat’s why I bought a vehicle that doesn’t have a turbo engine and just uses regular octane 87. However, 5k oil changes are still the way to go for most vehicles
@@alvinsimba734 🫡
They’re blowing because people are boosting above 25psi. I’ve done it 3 times. This last time I replaced the head gasket and have turned the boost down to 18psi. I’ve been driving hard as hell since February and no blown gasket.
These are all stock cars but yes increasing psi target will only accelerate the process
I have 2 questions bro. First is that if I find oil in the front pipe where the flex pipe portion is cracked, not a lot mind you, and car has 115k miles, what would cause that?
Also when you have worked on higher miles cars have you found the valves needing adjustment? It is a 2017 Civic.
Oil in front pipe would probably mean blown turbo or engine.
Have not ran into tight valve issues on these like some of the older Hondas.
@@BCautosolutions ok. power is good. little to no measureable oil consumption so I will chalk it up to the tiny turbo and cool running engine.
I’m tuned on a l15b7 on my SI. Should I just upgrade the headstuds? Running 26psi on pulls
I would, it’s only a matter of time.
That is going to be a MAJOR issue with those engines, just like the Ford 1.5. That head surface area isn't enough to seal. Fix will be new short blocks, like Ford😉
🤐
I’ve been working at a dealership 5 years. Up until about a year ago we saw few head gasket failures. Just the last month I’ve had 3. Still not many across the shop though. Apart from the head gaskets and regular bad injectors though, the 1.5 isn’t seeming super problematic.
I agree with you sir 🙌
I'm changing my injectors on my 1.5. I like the car but I'm also aware anything mechanical with electronics is going to have its problems. But so far no signs of a blown headgasket at 123000 miles.
I was looking at purchasing at 2001 LX with 58K. How can check for this issue? Take it to a mechanic and have him pull the entire thing apart? That would suck if I bought it then had this issue! Thanks
@@Whitesp44a mechanic could check pretty easily without tearing a lot down. Should charge less than an hour labor. But that can’t predict if the head gasket will fail in the future.
@@jamieharris74 Think I should stay away from the Accord all together? Yrs 2019-2022 As a used vehicle. Appreciate the responses.

Thank you
If you do the upgraded studs and sleeves does that solve the problem or are you just kicking a can down the road?
At that point it’s pretty solid although if your pushing for power then you have to worry about oil pump and rods
The si is a manual. You tend to apply the accelerator more towards the higher revs. This seems to me more to do with people pushing it in eco mode in an automatic and just making heat. Premium gas would help, but if you know you always expect more, keep it in sport mode. Lately, car manufacturers have been trying to hit peak boost earlier. For instance, the mazda 2.5 turbo hit peak boost at 1200 rpm. But its not that bad because its in a bigger motor.
Yup. Tons of heat and stress at lower rpm’s
