A midweek teardown? whaaaat? Yep.
Today's patient is a B18B1 from a late 90's Acura Integra LS. This is a 1.8L DOHC 4 cylinder that makes 142hp and 127tq and can be found in 94-01 Acura Integra although there are many variants found in many other vehicles. The B series engines and many other engines from Honda/Acura during this period are why they have a reputation for being so reliable. That being said, it doesn't matter how good an engine is, if you don't maintain it, or maintain fluid level, it can be moments away from destruction. This engine died a frictionful, hot and painful death that could've been avoided. Hard to blame this type of failure on anything other than lack of maintenance.
Why am I doing this? I own and run a full service auto salvage business in the Saint Louis Missouri area called Importapart. Part of our business includes dismantling blown or core engines and salvaging the good parts to resell. We do not rebuild engines, merely supply parts to people who do!
If you're wondering if I've torn down a specific engine, I've torn down nearly 120 engines on this channel and you can look through them all here: • Blown Up Engine Tear D...
I really hope you enjoyed this video. As always, I appreciate all of the comments, feedback and even the criticism. Catch you on the next one!

love watching adam sandler make teardowns
This tear down guy is a lot funnier. Does Adam Sandler breathe on bolts to heat them up? Nope.
😂😂😂😂😂 I say the same thing
Oh shit, I thought it was Adam Sandler at first too! 😂😂😂
That's great lol
No way, this guy actually makes me laugh!
The rod bolts look like they just stretched until they broke as a result of them being near molten! For the engine to hold together that well under that kind of stress is absolutely amazing.
Pretty good testament to why people say the B-series is (nearly) indestructible
That was my thought as well. That didn't look like deformation from friction, that looked stretched. With the rod cap being bent in half and the end of the rod being splayed out like that, you don't get that kind of damage without heat. Otherwise they would have just snapped. The entire area was probably glowing cherry red when it let go.
Perhaps a small beaver did it
Stock Rod bolts on B series engines are the weakest link compared to other companies in the engine.
I had an '88 Accord LX-I. It didn't care what was going on if it had just over one quart of oil. Probably the best engine I've ever had.
"Burns a little oil, not locked up" That connecting rod was epic.
That engine seems a lot tougher than today’s engines
When taken care of properly, a Honda B series motor will last a long time, even if driven hard. It is the absolute best line of motors Honda made before the introduction of K series.
My 2.0 is the best 4 cyl I ever owned
Just once wouldn't love to have somebody actually tell ya the truth about what happened! "I was going down the road at full throttle, stereo up full. Smoke was blowin' in the rearview mirror. The engine was makin' a chunky noise and was slowing down to a crawl, I kept my foot in it until it just quit! I think I last changed the oil 3 years ago!" lol.
Pigs will be flying that day
YAY! A Wednesday teardown! What have we done to be so blessed?
i was thinking same
@@snackler6102 Really? He doesn't look Druish.
*yea*
“That’s one happy pickup“ 😂
I laughed pretty hard at that one 👌🏻
I laughed harder than I should have at that, too. :)
19:34 "That is one happy pick-up" - I laughed way too hard at that. LOL
A Wednesday teardown? Everything's coming up Milhouse!
Today, I learned a new saying.. never heard anyone say “Everything’s coming up Milhouse”
@JoeyLovesTrains you must be younger than 30.
@@travissmith2211 you are correct
@@JoeyLovesTrains it's a line from the Simpsons ruclips.net/video/M67E9mpwBpM/видео.html
God I love the Simpsons. Just don’t pull a Ralph and bend your wookie.
Agree with pistonavatarguy, the broken rod bolt looks like a tensile test specimen - where you pull a cylindrical sample to overload failure. It wasn't melted but from type of damage & color I'd guess 800-1400°F. That engine became a blacksmith!
In-engine annealing! It's not a bug, it's a feature! 😅
Plastic deformation?
Hooooooooooold up...and engine teardown? On a Wednesday? A b18? Crazy world we live in, and I love it
I'm SHOCKED that you got the crank bolt out so easily! I worked in a Honda dealership for 14 years, and there's a special tool used to break that loose. The number of times people have asked to borrow that tool is insane. Also, I never knew they had "Bluetooth" con-rods in the B-series engines!
It's had the timing belt done, so someone already broke it loose.
187 lb/ft torque spec for that crank bolt. And I have that special tool too!
@@wm8728 The reality is, almost no one in the DIY world torques back to that spec. It is by no means impossible but after you notice it is a woodruf key anyway, you go as far as you can before you buddy slips with the screwdriver in the ring gear teeth then drink a beer. Yes, I know you are the exception.
@@michaelkrenzer3296- any impact worth a damn should be able to pound that sucker on there “good n tight” on the highest setting. Been doing it for years. Haven’t heard of crank pulleys flying off yet. 🤷🏻♂️
@@I_know_what_im_talking_about The problem isn't that it's too tight for an impact to remove. Plenty of people have spun the engine over without the bolt coming out.
That generation of Honda engines will always have a place in my heart. The B18C1 and C5 held the highest horsepower per liter 4 cylinder for many years.
B18B1 Integra getting beat on? Never! The B16A1 I had in my CRX was so much fun, that never got near the red line, noooope.
When I saw that piston pop above the deck, I just busted out laughing, trying to figure out how, then I saw it go up even more, and almost fell out of my chair.
My Integra B18 has 362k miles on it and still going strong, maintenance is key!
“All kinds of species of pieces” (peeceees) haha.. that’s my new favorite 👍🏻
I just bought a bone stock Integra with this exact engine, so I'm excited to watch this one more so than normal.
Wow, pretty rare. Those got riced out and driven into the ground. Haven't seen a clean one in like 10 years.
@volvo09 I honestly just got super lucky to find it. The guy I bought it from didnt actually have it up for sale. He was the first owner and had recently bought a new car and mentioned to me that he just wanted it out of his driveway so I made him an offer and he took it. I offered him book value, and he acted like he had just got over on me, lol. Little does he know I'm the one that came out on top that day. It will stay bone stock as the way I found it the only thing I'm gonna do is a little body work and I'm only doing that because it's necessary.
@@Adam-nv9zo yea you're the one who made out for sure. Unmolested hondas and acuras are fetching premiums
@@2strokeFORever definitely.

Mid week teardown! What a great use of my time on my snow day.
You must be somewhere near the Canadian prairies.
Close to Minnesota?

@@xXxDETZxXx yep the same blizzard Manitoba got.
Eric, I would love to see Wednesday teardowns more often!
I could watch one every day!
Outstanding carnage on that little mill. Shame they let the oil get low.
If that engine had a tiny bit more oil in it this would never of happened. watching that piston rise up from the block was a religious experience for me!
I'm not an artist, just an idea man, but how about a "happy oil intake nom nom nom" t-shirt? The oil intake at 19:35 is a great model for it, add in some RTV and bearing foil and piston nuggets - done well it'd be a merch win!
This is the second Honda engine on the channel that literally cooked itself. That Honda Fit engine surely did, but considering they are naturally aspired and still managed to put out that much heat to do that is rather an amazing testament to how well engineered the engine is.
Amazing! I didn't know Acura had implemented the variable slope rod that long ago!
not a well-maintained engine but amazing how clean the intake ports stayed in the days before GDI
Perfect timing for the type of day I’m having. Thanks for the tear downs!!! Keep up the great work
We hope u have a better day
Wow! I want that Piston and Disconnecting Rod. That has got to be the BEST conversation starter of all time.
9:08 introducing us to Red! Literally that's the name of the pry bar I use all the time🤣🤣🤣 Ol' Blue has a friend!!
Stripper glitter makes for a HOT time, with the BOOM BOOMS BOOMING you'd never the little man inside hollering "LET ME OUT" ! Thanks Eric for another fine job.
Is it Christmas already!? A midweek tear down Jesus Eric You're coming through clutch this week
So what I've been getting from this and other videos is that, if I want piston mcnuggets and homemade glitter, I just need to find a nice Honda engine and rev the nuts out of it with little oil and the rest will take care of itself. That tip should be on those 5 minute craft channels.
All sorts of Species of Pieces had me rolling.
WOOHOO midweek teardown!
A self removing piston/rod and a rod cap that's been smashed, crushed and folded beyond recognition. That crankcase must have been looking like the inside of a volcano before it blew.
The gods are smiling on us! A mid-week "who done it" video. Far out!!😊
I did own that engine and I put 198k on it. Such a fun efficient durable engine.
Definitely needs valves adjusted some.
Definitely oil starved.
I feel so at home with a B-series teardown
I think the rod-cap bolts look like that because they have been pulled apart when semi-molten, that's why they come to a point.
This brings back memories of my own Integra. It was my favorite driving car of all the ones I’ve owned. The first B18 in it made it to 314k miles. I wish I could have kept that one.
"...all kinds of species of pieces" had me wheezing...😂
And then I heard "happy pickup"...
Stick a fork in me, I'm deader than this engine block.
I bought a 1982 honda accord that had been driven until it quit. After I pulled the oil pan I found a torched piston and I surmised that it blew all the oil out and there was not a single trace of main our rod bearing in that engine, It was all in the oil filter! "Talk about a real stinker", The crankshaft was case hardened blue and all the journals were smooth! All the rods were intact and came apart very easily. Just for giggles I took the crank to my crank guy who was not surprised and told me that they do not grind these cranks because of they did case harden them from the factory back then. There was no damage to any of the journals at all! A used 250.00 engine was put in its place and it was happy again. BTW I only gave 50.00 for the car; )
I love how the crank was heat treated inside the block. Someone forgot to quench the crank tho.
Hell yeah... Honda content...my favorite on this channel
How could they not hear that knocking away?
I've noticed a large number of connecting rods becoming disconnecting rods. I hope it isn't contagious! There has also been a lot of ventilared blocks. I'm sorry for your loss. 😅
I was about to comment, 'well, that's a first,' but I was beaten to the punch. Never a dull moment.
Man I better get a rebuild going in my Integra LS. I've been such a cheapskate😓
Holy... If that end cap wasn't forged to begin with it is now!
I haven’t laughed like that in a minute watching you pull the piston out was gold 😂
A bonus midweek teardown? You're spoiling us, Eric.
The B series crank bolts arent the ones to worry about, they normally come off easy
It's like you read the comments or something! I ask for it and you gave it! Thank you so much!
You need an impact driver for those oil pump cover screws, Eric.
One of my favorite parts - the exit of the water pump!
What a welcome surprise! Love a Wednesday teardown!
The heat and pressure required to cause that amount of damage are almost inconceivable. What I find most impressive is the damage remained mostly localized to that one piston.
that was awesome eric! ejecto piston integra motor! the bottom end carnage that was more of an implosion than explosion was the most impressive and the fact that cap folded itself in half and stayed inside the confines of the engine housing is nuts! another educational experience thank you!!
I often hear about how much noise the engine must have made, but this one must also have been making a lot of smoke. It was burning itself to death and the inside of the car must have stank before the engine "shut off".
"I just wanted to get it home!" --Blonde
It never ceases to amaze me how well a Honda engine can Just commit Seppuku and the Owner be Like "Yeah Has a little squeak on start up but once you get it warmed up and Crank the radio real loud you hardly notice it!" I mean that Piston that decided it was tired of being in the Cylinder then seeing the other end of it was Just wow Thanks for bringing Much entertainment on this Crappy Friday morning For me at least.
😂😂 that was hilarious when you pulled the piston out... beyond spun bearing
Nuts episode! Never thought the upper half of the connecting rods attachment could look like that. Would love to see a BMW N52 if you ever get a hold of one.
Mid week tear down? Nice!!
Sweet!!
An adjustable connecting rod!!
That’s an import street racer,
Mod!!! Taking moms car out racing!!
Nicely done!!
The B series is a lot like the D series. Stock, they're tanks, and will run on as little as a cup of oil for at least a little while. That engine got a negative quantity of love, and almost no regular maintenance. The hole in the block is in the main oil gallery. The lack of oil was the root cause.
They could have went so much farther than 215k on that poor engine :(
@@Amdfan900 agreed. Regular oil changes and maintenance have carried several b18bs to over 300k for me.
Yeah, it was dark inside and spun a bearing on the last rod - furthest from the oil pump. Probably run low on oil.
@@volvo09 The oil in that block wasn't synthetic, and was starting to degrade to the sludge point. Likely both low and wildly past the OCI. I've watched that happen before. 100% preventable if the owner had just given a single crap.
Surprise tear down!! This week just improved!!!
@19:35 "One happy pickup" LOL
I remember working on engines like this back in the day before ratcheting wrenches were a thing. I hated my life, 1/16 of an inch at time.
Man, that #4 rod journal and rod had a really Medieval look to them, like a blacksmith hammered those out!
The rod cap bolts on this tear down were something. The whole bottom end was something but those bolts where intriguing
When you said "that's one happy pick-up" I lost it 😂😂😂
Genuine laugh out loud moment when that piston popped up for the second time!!😅
And also the happy pickup got a laugh too
😀
I laughed so hard at the self extraction of piston four. Thanks for another great video
My son-in-law ignored my warning to top up the oil every week in my daughter's 1993 Accord. Instead he added oil when the oil light went on. That went badly when the oil light failed. He thought it was out of gas on the freeway; it was really out of oil altogether. My daughter implored me that they needed it to work for another six months. Sigh. I removed the oil pan, releasing a sigh of air that smelled like engine death. There was a small puddle of oil in it with an ounce or so of yellow glitter in it - I had struck gold! No... wait.
I polished the crankshaft journals with crocus cloth, bought new rod bearings, plastigaged them (they were all in tolerance!) and put it all back together. Ran the engine for a minute with cheap oil, drained that and put in real oil, and did a compression check. Two of the cylinders were okay enough; the others had 60 and 40 lbs compression. That's okay, isn't it?
It ran for six months, when she was able to trade it in on a Sienna. I will never forget the Honda that survived 200K miles and then being run without oil.
@16:10 cylinder #4 definitely playing "peek a boo" 😂😂
Excellent video as always. Thanks!
It had the best auto parts store grade oil pan gasket you can get, fel-pro blue with metal inlay, ran one on my GSR. It was probably using oil and the oil pan gaskets on 10/10 B series leak. Not a great loss for a B18b block, they are popular because they are cheap and compatiblish with VTEC heads, the B18b head is way less valuable than the VTEC variety. Years ago I saw an Integra LS engine bay stripped bare, just the cylinder head complete with valves, was on the ground cast aside worthlessly.
thanks for awesome teardown again!
I love when he was doing the piston test he says ooo it spins 😂 and before that he says uh ohhh
Thanks for the bonus episode!
thanks for the video. very interesting and fun to watch as always
B18 are my favorite engines, we gotta see another
Amazing damage! Another great video, congrats on passing 200k subs, well done Eric!
What a wonderful treat to get a mid week teardown! Thank you!
What a nice surprise! Thanks, Eric!
Awesome...a midweek teardown! Thanks for the extra treat Eric, you rock man!
Hey this is really great. I love the teardowns. I enjoy your content no end. And your humor
Great Wednesday surprise. Wasn't expecting this. Thank you Eric.
The 2.7 V6 was reliable as any Honda engine and zero valve adjustments homie, kick rocks
Good luck keeping it from leaking oil.
@@I_Do_Cars I think your mistaken the 2.7 Honda for the Acura V6 engine with the driveshaft that runs thru the oil pan? Bro dont try and school me on Honda/Acura, you will loose and cry cowering in a corner calling for mommy
@@girthy10incher23 2.7 with a driveshaft through the pan?
No, the C27A4, 88-90, 95-97 accord and that sterling thing.
All transversely mounted, and all leak oil profusely.
Good luck chuck.
@@I_Do_Cars May wanna to re-read what I said, the 3.5 RL has the axle through the oil pan oh but you know it all already right, damn bro you have little mans syndrome? What are you like 5 feet 2 inches? You think you have a clue but in reality you dont.
Incredibly strong engine. It looks like it ran without oil for quite some time and it took some effort to finally let go.
Enjoyed every minute. Great, clear camera work also. Thanks
Eric your good at this engine stuff, have you done this before?
Love your channel man!!
The more the merrier! Love the midweek stress relief of seein a new teardown. Thanks man
Oh so close to 3 cylinders! Great video!
As a younger man attempting to remove my B18B crank pulley bolt, I broke down and wept because this fastener had defeated me. The next day, armed with a 3-foot extension pole...I was victorious!
3 teardowns in one week Eric you sure are spoiling us, keep up the amazing work as always cant wait for an update on the Esprit
I laughed so hard when the piston popped it's decapitated head out.
Drink! every time Eric giggles like a grade schooler
Nicely done... As always I'm hooked on your tear down videos, the live stream was cool, and I hope you do another soon... As always Thank You Eric, and I'm hooked...
So happy to see this today! Keep up the great work! Hey, don't forget the t shirt and merch idea! I'd buy several in a minute! Happy Easter... He is risen!
outstanding eric
