Car engine autopsy no oil change for 75,000km!!

- Опубліковано 6 лют 2017
- Let's face it, plenty of us 'skip' oil changes, delaying that inevitable garage bill. Can it really cause any harm to the engine? Or, like most motorists think, it'll be fine!!
I was lucky enough to stumble across an engine that had been run for over 75.000km without an oil change, not even a top up, ultimately the inevitable happened....so, I made a video highlighting all the damage caused by extending oil changes, sure this is a bit of an extreme example but I'm hoping it get's the point across!
Enjoy...

75,000km before seizing actually isn't that farfetched... We had a customer come into the Ford dealership with a seized engine on their 2.3L Fusion with 125,000km. When we asked her when she last got her oil changed (no sticker on the windshield) she ACTUALLY said "But it came with oil in it". She bought the car new off the lot with less than 10km and never had the oil changed ONCE.
+07CVPI Bloody hell. Well, she got a few more km that this customer. It's amazing really how advances in engine design, modern materials, coatings and of course oil additives have all helped make the engines so much more tolerant to such neglect.
Thanks for your story and feedback. Cheers Andy
07CVPI that's the same 2.3 engine in the Escape right? I have one and glad its a solid engine. This do change oil on mine regularly though
+07CVPI It's a crazy world we live in! Can you tell me how you came across the video? There has been a massive increase in views these past few days and I'm keen to understand why? Many thanks Andy
This was on the recommended videos but then I watch a lot of different videos from bikes to guns. Woodwork, History etc..
It's ending up in people's recommended videos
Andy,
Before retiring, I worked for Honda Mfg. for 15 years. It was a pleasure watching you disassemble the failed engine after correctly diagnosing the problem! One of the things that I was reminded of was how well engineered Honda engines really are. They really are great engines and if taken care of can go well over 300,000 miles. Like you pointed out, the engine was really neglected by the operator. If it had been maintained like it should have been, it would still be running.
Great Work! I'll be watching more of your videos!
This is an exceptionally well-designed and manufactured engine. That it survived so long in the face of chronic abuse is a testament to Honda's superlative engineering.
Definitely :-)
I love changing my oil, I can't wait for oil change intervals. Gives me an excuse to do more work on my car lol
your car will love you back for maintaining it correctly :D
I used to when I was younger but now I need a proper place to do it. Flat floor, inside, proper tools, etc. I hate getting into something and have it start to rain or whatever. Plus where I live it actually costs more to do it yourself as opposed to having someone else do it. Plus the places where I live do a bang up job of topping up all the fluids, checking everything under the car, etc. I used to ride share with a guy who changed his own oil...and didn't look for anything else. His car was a POS and one day on the way home, just off the highway, the brakes failed due to a rusted out brake line.
Never rode with him again...his car was a death trap.
@@muskokamike127 where do you live?
I used to live in Colombia, and there people rarely work on cars. Mechanics are usually very honest and cheap. Plus, most people (myself included) live in apartments with cramped underground parking lots, so working on your car would be a pain in the ass. There also aren't any places such as autozone where you can go buy tools, and the only place to get parts is the dealership (or illegal chop shops). The only thing people do is change out their bulbs and, maybe, rotate the tires. In the end, it was just much easier and often less expensive to go to a mechanic, which is a shame IMO.
@@MrFastFox666 I always thought about opening a "do it yourself" garage. Lifts, jacks, basic tools for an hourly rate. Allows people who want to work on their cars a place to do it safely clean and dry.
BTW: google Muskoka, (Ontario).......that's where I am.
Me to 20 years ago.Not so much now.I never take my trucks to the mechanics unless it's something I really have no idea how to fix but most things are pretty easy to figure out and if it's something you don't know as long as you have a code reader I can help you out I change my oil every 10000 km and I've never had a problem with sludge. I live in Canada your vehicles rot away long before they stopped running. Even if you don't put oil under it every winter it will buy you a few more years but eventually the salt will win...
If a Honda engine can still run when it is this abused, imagine how solid it would have been had it been properly maintained!
Honda walk behind lawn mowers are known to be extremely reliable for years even with some abuse (sticks, roots small stones) so it doesn't surprise me the car engines are also very durable.
@@AuronFFX I agree, I have a 31 yo HR 194 and a 15 yo HRH 536. Bought them second hand for a bargain. Besides some dings on the outside, they're spotless mechanically. The engines just purr. They're a joy to use. Basic maintenance like oil and air filter change, and they'll last me forever I have no doubt.
@@em4703 our old family lawnmower with a Honda engine lasted for close to 20 years but only failed because the deck rusted out and it flung grass all over. The thing even hit a large rock once and the blade was wrecked but engine kept running like nothing happened. Actually I don't know how old it was I was almost 20 when it failed and it was around before I was born.
All engines made in the last 30 years will last 300,000 miles, with a couple of specific exceptions. Honda makes good engines, but so does everyone else, even if the vehicles they are put in are not so good.
Note how the entire crankshaft gets darker over by cylinder #4. This is a classic oil starvation issue. The oil pump is right next to cylinder #1, and by the time the oil gets over to cylinder #4, there is now an insufficient supply of oil to keep things alive.
You are an amazing teacher! Very natural and clear.
+Mike Tunstall Thanks Mike....really appreciate your feedback. Pleased you found the video interesting and helpful by the sounds of it :-)
Definately! I would love to come to you for an apprenticeship, if I wouldn´t be too old and too far away. Keep going !! Nice vids!
I have to agree! I only arrived at this video by a UA-cam recommendation, and to be honest I thought I would skip through chunks of it just to see the damage - - I have watched every minute of it, and what a fantastic video! You have another subscriber (from the UK, where I suspect you originate from, going by your accent?) and I look forward to watching future videos.
+fulwell1 Thanks Fulwell1, it's great to get the feedback & I'm pleased you found the video interesting. Yes, I'm from York originally but left the UK at the end of 2008 to live in New Zealand. I may come home one day.... Cheers for now. Andy
I wouldn't recommend coming home - the country has changed dramatically in the past 10 years, and bluntly, I don't like what it has become. If I could afford to move to NZ or Canada, I would do so tomorrow without a moment's hesitation.
I have to say, watching this video has been like watching a horror movie, expertly filmed. You have the early part where there is character development, and you actually start to care about the people portrayed in the film. Then you have mysterious events that happen to them, which piques your interest. The tension builds as the events become more and more horrific, and your concern for the characters starts to build. All this, while you catch just enough of a glimpse of the monster to hold you to your seat, searching for a longer view. And then at the end the great reveal, when you are finally able to see the villain, and it makes you go "holy crap!" Bravo, and well played!
+phobet Thanks. I have never had it put that way but your interpretation is Fantastic. Cheers Andy
Definitely NOT made in America. Here, most posters are unable to think, much less spell.
Engine autopsies are fun stuff.
ZIGgassedUP - Not if you're paying the bill... LOL :-)
Jokes apart I agree.
Auto-topsy, to be exact.:)
Women driver you said ? Ask my wife where the dipstick is and she'll point at me...
+Michael T. Classic! :-)
That's no lie... I always ask my girlfriend when the last time she checked her oil is and she lies right to my face. Last 3 times someone else has changed her oil it came back a full quart over full and she had no idea. Why the oil changer is just giving away extra oil that it doesn't need is a mystery to me.
Did an oil change on my buddy's wife's car a few years back just to help him catch up on some chores and drained as much bearings out of it as I did oil, which is to say about 1/8 as much oil as it should have had. She swore she checked it too... Shockingly that car continued to drive for several more years.
Both of us are car guys but we both have the same problem in that the car has to actually be here for us to service them. When they're out and about running around 18 hours a day it's pretty hard to keep up on them. It's frustrating.
spun rod bearing done it yet not so bad. love how in depth your vidio is =) not many realy show this level
built many b18s a b c and frankenstien honda engines. seen a 2.4 quad 4 near as bad. never one my hondas
have a piston and rod from a hyrdro locked b18c1 ... bent did not blow the engine. fixed it and its still running. that was near 8 years ago for a friend. i keep the piston and rod as a trophy for work done well.
Whatever process Honda is using to treat the cylinder bores in their aluminum blocks, it's incredibly strong. I've pulled apart a few Honda 4-cylinder engines, all of which were over 250,000 miles (400,000 km), and all of which still had crosshatching on the bores. None of them were ever rebuilt, and when I threw one of the blocks on a boring bar just out of shear curiosity, a single bore destroyed three carbide cutters before I gave up.
I'd love to know the process Honda uses to get that level of surface hardness out of aluminum!
+rhkips That's incredible to think the engine has done so much work and the bores aren't showing any signs of wear.
I was suprised by that fact and had assumed that maybe the engine had been rebuilt at some point but after hearing your experience it's obviously not the case.
I really couldn't resist doing a video on this engine given what it has been put through. I'm hoping it will give my students and others an insight into the importance of engine oil & checking/replacing it at the correct intervals.
Pleased you enjoyed the vid & thanks for the feedback. Cheers Andy
I don't think I've ever seen a "modern" Honda engine get rebuilt. The only reason I've ever had them apart is to build and modify for people. They're so inexpensive to acquire used, there's just no value in trying to rebuild them!
This was a great video, and I do tend to enjoy stuff like this. Knowing and understanding failure modes is just as important as understanding proper operation, and dissecting a total failure like this really gets you thinking about how all these tiny, intricate parts work together. :)
rhkips It is the heat and pressure, the subsequential cooling off cycles, that finishes the hardening process. By just using the engine for a few thousand of miles.
Correct me if I am wrong but I have always been under the impression that the actual cylinders on all engines with aluminum blocks are sleeved in some type of steel. Even if the pistons are aluminum the rings themselves should be some type of steel as well.
Most of the time, that's absolutely correct! There are some engines out there (some Honda engines, and I believe some Toyotas as well) that use a hardening process on the aluminum itself rather than sleeving the block. :)
When they give the excuse of 'the car never told me it need an oil change' is similar to not making dinner because your child never said it was hungry.
You change your oil regardless. You make dinner regardless.
But then god created women in this world...
This was very interesting. Thank you for taking the time to record this. There are so many times I've wanted to do this type of thing but never seem to have the time. It's very educational and really makes you appreciate how important proper maintenance is. Thanks again Andy!
Thank You Mr Scott, appreciate your feedback. Cheers Andy
A true pro! Even pulling down a scrap motor he treated it with care..Nice one!
I sat through damn near the whole hour and a half video and I have to say I admire the thoroughness of the teardown. I don't think one thing was left out. This is exactly the way I tear down engines. Leave no stone unturned.
+Boxer Tech Thanks Boxer Tech, pleased you liked the video & appreciate the feedback. Cheers Andy
Tom Heron / 13 January 2018
Andy Young, your video presentation I would define as a CLASSIC, all car owners should watch, as it stresses the importance of proper regular servicing.
From a retired long time experienced/qualified marine engineer.
I give you a top score of 10/10.
+Tom Heron Thanks Tom, is great to get such good feedback from a professional time served Mechanic.
Pleased you enjoyed the video. Cheers for now. Andy
I change the engine oil and filter every 10.000km on my BMW 535d. On my Cosworth I changed the oil every 7.000km. "Long life" intervals are for gamblers.
Those are good intervals. Just imagine the carnage if the turbo bearings in your 535d were to fail catastrophically at 50,000 RPM. I bet the turbo would be even more sensitive to shitty oil than the engine is just because of the high RPMs involved.
+KiwiPowerNZ You could be right...plus many of the bits will be drawn into the cylinders and destroy your engine too....
Cheers Andy
10.000 km is the limit vw longlife oil say 30.000 no way no oil can last that long the turbo is the worst oil killer i have seen vw engines break Down at 50.000 km
im a BMW mec and i have seen vw engines failed by the long life oil change i change my oil every 10.000 km and the filter Again after 5.000 km
you have two turbo chargers they are breaking Down the oil and oil change at 10.000 is perfect
I've taken my 99 gmc yukon heads off (it has 261,xxx miles) and the 5.7 vortec still has cross hatching. really doesn't surprise me how people destroy their cars.
+sneakysnakepie1 All these engines need is to be serviced at the right intervals. It really isn't too much to ask is it!
Andy Mechanic to some I think so
Andy Mechanic to some it may be too much to ask. I on the other change my oil every 5k kms or 6months whichever comes first. I have 2 daily drivers so I actually rarely reach 5000km in 6months. Costs me about 60 us dollars per service. Not bad
Thank you for doing more in depth and real time videos. As a beginner it's so easy to miss steps while following other videos, this is clear and concise, thank you.
Cheers Amanda :-)
Very good, thanks for posting. It’s refreshing to see a mechanic not bragging about how great he is, and presenting information in a professional manner.
Thank You. Andy
People that don't maintain their vehicles shouldn't be allowed to own one. It irritates me to no end when people think all they need to do to a vehicle is put gas in it.
Yeah, I suppose the government would be deciding which folks should or should not own a car. Freedom includes the freedom to be an idiot in how you treat your car.
It's nobody's problem but their own. Good business for mechanics too.
Dan Mart You make an EXCELLENT point! There's nothing in the Constitution or the 10 Commandments that says "Thou shalt not be an idiot!"
Dan Mart Its none of the govs biz. It still dont give you the right to point 2 tons of shit maintained mass at my family seperated by inches when we merge. Go hit a tree at 70mph. Thats what youll get if you hit head on at residential road speeds.
You should see the shit condition techs see in the garage on any given day. They should have the right to kick your arse on the spot for endangering their fellow man because the customer is to stupid or cheap to maintain a safe vehicle.
I love it when they don't take care of their stuff, it keeps me working when I come to salvage it. People that cannot put their face to their words shouldn't be allowed on the internet, it's not a mask for people to troll around on like a nazi with anonymity.
i cant believe i spent an hour and half watching some guy strip a motor.
+bryan allen Haha! Cheers Bryan, good to know you found it interesting. Andy
Yea fun Stuff :D
better n watching some guy motor boating a stripper!
What do you mean? That’s a free education you ungrateful shit
Im 11 minutes in, i can see why u stayed for the whole video lol
5hrs out of I'm sure your very valuable time just to inform the public about what can happen if you neglect to change your oil. Your an amazing fellow. Thank you.
I didn't think that I was gonna watch this whole video, and now I'm 15 minutes in and definitely gonna watch this whole video. You're a great mechanic, and I found it pretty entertaining to watch someone take an engine apart with an impact gun, a pry bar, and a hammer.
Could still see cross-hatching on my Toyota Camry after 190,000 miles.
Christopher Stevenson as long as it’s been looked after, that’s normal. I’ve stripped engines in that kind of milage that have been looked after and the ring gaps and everything have still been in spec. I’ve pal had very high milage cars on the dyno with the output bang on or only a negligible difference to what it should be. In a well lubricated engine, none of the parts should technically actually touch each other. In theory at least.
I have never seen a rod bearing that bad, that's amazing. I was an ASE tech for GM for several years in the 80's and I've seen a lot of sludged up engines due to poor quality oil back then. That takes the prize, however.
I should try and find pics of the one that came out of our Citroen, bought it with a thrown rod on it's 1.9D engine (known for being tough motors, and never heard of a thrown rod on a non-turbo till this!) and the upper bearing was worn right though, clean in 2 while the lower one was badly run & burred over like the one in the vid.I think the cause was the same in that engine, run out of oil. Difference being that the guy kept on driving while it knocked right up until the bolts vibrated loose and it dropped the cap.
+dan mackintosh Exactly....sounds identical but with a heavier foot!! Cheers for the feedback Andy
Not unheard of. My AU III Falcon has 276,000. I was given it late last year with a RWC and an assurance it had been serviced. Decided it was time to do oil and filters. Found the date 10/06/14 written on both filters and I stopped driving it immediately. I had checked the oil regularly and topped up as necessary. The sludge that came out was horrific. Now down to oil changes every 2 months until it starts to come out clearer. Also using a flush before each oil change. Tribute to Ford that it was still running. No sticker on screen just a "mechanic's" assurance it had been changed. It doesn't leak oil, no smoke and no other side effects. Lucky escape. In case you want to know I came across the channel looking for a video to explain changing the. water pump on my other AU.
very glad to have come across your videos. I really appreciate how you present information in such a straightforward and scientific manner. Cheers!
A very thorough autopsy, nice in depth examination that shows the effects of bad lubrication and how quick it can kill an engine. Years ago I pulled the valve covers off a small block chevy that had zero maintenance and the oil had sludged up so bad in the top of the heads under the valve covers it wasn't even draining back into the block - you can guess the rest of the story-lol
+yambo59 Hi Yambo59, Thanks for the feedback and your story too. Vehicle owners in general are checking their vehicles less these days so problems like this seem to be cropping up more often in my opinion. Can you tell me how you came across the video? There has been a massive increase in views these past few days and I'm keen to understand why? Many thanks Andy
Well I watch south main auto and eric the car guys videos, and near as I can recall your video possibly came up as a suggested video at random after watching one of my usual vids. I also sometimes scan at random looking for new channels so it was one of these two methods I came across your channel im guessing, Ive always liked taking things apart since I was a kid, and built a few engines when I was younger, mainly small block chevys. I also find it interesting to find out why or how something failed, theres almost always something to be learned when a part or engine fails. In any event ive added your channel to my list of car repair videos, I like your thorough approach when looking at the wear patterns and failure points.
+yambo59 Thank You. Me too...diagnostic autopsy type strip downs of failures are my favorite too :-)
One has to ponder... Have Honda done away with oil & temperature warning lights on the dash, or did this lady think that the pretty red lights were just for decoration?
Reminds me of my ex wife. When her Mazda 626 engine siezed, I asked her if the oil light had come on - her answer, "I thought it just meant it was due for an oil change, so I thought I'd leave it 'til the next service..." :-X
+Yorick Hunt So very true Yorick but it's not limited to the fairer sex either!
+Yorick - see my comment above to safn1949 for proof that it's not just the ladies that can be this oblivious...
Definitely not just the ladies. The big difference between the two sexes is that women will offer a sheepish look when confronted with the facts, whilst men will argue 'til they're blue in the face that there were no warning lights and that it's a result of shoddy manufacturing/engineering rather than their lack of observation/maintenance/care.
+Yorick Hunt Very true...I agree completely. I found with my students that the girls listened and took the info in whereas some of the lads just enjoyed pretending that they knew everything.
The more we learn the more we realize how little we really know.....
VWs since the Mk4 Golf ignore the oil pressure switch at idle, most don't check it until 2000 RPM! Even our 04 V10 TDI ignores the oil pressure switch at low RPM!
Great video! Like watching a Pathologist finding the cause of death. So sad to see good equipment like this little engine neglected until early catastrophic failure. My grandfather taught me..."if you take care of your equipment, it'll take care of you."
Thanks for taking the time to look in detail at the damage. I changed the oil for my step-daughter once ... just a few drops. I can't believe it didn't seize! Makes one wonder when they buy a used car!
It would have been interesting to cut open the oil filter, most likely it was so
plugged it was bypassing the filter completely.
+audiefied I agree, I think I had planned that at the start of the video but forgot sorry. Also....
Can you tell me how you came across the video? There has been a massive increase in views these past few days and I'm keen to understand why? Many thanks Andy
Hello Andy, you must have made to the big leagues LOL
Actually this video was in my recommended video section.

Andy Mechanic Andy Mechanic Hi I'm also a new viewer this came up as a UA-cam suggestion. I watch pine hollow auto diagnostics, South main auto, scanner danner and schrodingers box. So this sort of thing is what I enjoy watching this video has been fascinating thank you for showing us. Steve.
+Steven Watson Thank you Steve for the feedback and for taking the time to watch my video. Pleased you enjoyed it. Cheers Andy
me i was watching a shity VLOG of some vloger youtuber with nothing interesting watching 30 seconde of it i saw this video suggestion really good work and nice deep view of the engin thanks !!
this is why I change the oil myself and regularly with top brand synthetic.
i have no idea how I got here, Andy, yet this is a truly fantastic demonstration. Gonna watch more!
Thanks :-)
I was once a student to this master at Unitec(Marine Engineering)He taught me a huge amount knowledge about cars,diagnostics and I still use them till this day.Its great to see your still doing what ya love.This is what your born to do,Keep it up Andy Love ya work
+Forced Induction117 Hey, awesome to see my old students still watch my videos. Great to hear from you. I left Unitec at the beginning of May this year as I was offered an amazing opportunity working with Yamaha New Zealand in the position of Motorcycle Technical support for all the dealers across the country. It's an incredible opportunity which sends me all over the North and South islands helping the workshops solve problems, assessing vehicles used in agriculture, supporting the sales team and even participating in the off-road trail rides Yamaha put on every few months. It's very hands on, exhausting and very long hours but a unique position.
I wouldn't change working as a Lecturer, I found it very enjoyable helping pass on the knowledge with the aim of helping people secure a career in Automotive & Marine. Good times indeed and I made a lot of friends during those 5 years.
Keep in touch. Cheers for now. Andy
Andy Mechanic Wow awsome job mate.Sounds like the perfect job for you.Yea just thought i would say thanks for everything.Keep it up and i'll keep watching :)
cheers Michael
Apart from the obvious... To me that engine shouts build quality.
"Woman driven car for sale, no dents, in Prefect condition, first hand from dealer, no haggel price, properly maintain, will take nearest offer"
Girls think cars are like horses, just feed am and clean em, just love the flashing lights on the dash, what a shock I need a new car again. Interesting that the cam chain was still good. Another good video.
I have to say I LOVED this video. I've never been able to do an engine tear down so this was great to see. And truly getting to see the damage that was done to so many components was very enlightening (as opposed to just taking off valve covers and maybe the oil pan). Your video was very thorough and you explained and showed everything very well. Made me feel like I was in the shop working with you. Hope you enjoyed that beer (or cider) after you were all done! Cheers!
+Jennifer May Thanks Jennifer :-) Yes, I remember, that cold cider went down a treat.
Pleased you enjoyed the video & thanks for taking the time to send through your feedback. Cheers Andy
Awesome teardown video. Thanks for the time!
When you did the swap did you check the replace engine bulb on the cluster? Maybe it was burned out from all the hours it got.
Seriously good education! Was fascinated thru to the end. A great big thank you to you. Your analysis was spot on right from the start. All the best to you. May you reach one million subscribers and beyond. Wish all mechanics were as honest & wise as you.
New subscriber here from U.S.A. We really enjoyed this video and examining what happens all over when no care and oil changes have been done after 75KM. Engines are getting built so much better than they used to and can now handle years of misuse and lack of lubrication.
A man and a woman were in line in front of me at an auto parts store.
The man asks for a headset for a '65 Chevelle Mailbu.
The clerk asks him: "Big block or small block?"
The lady asks for a headset for a Chevy Vega.
The clerk asks her: "Stereo or mono?"
This makes me never want to buy used in my life 😂
I never buy used. But whoever gets my trade ins gets an extremely well maintained car.
Very educational. Clearly done and very patient in explaining every detail. Yes it was long but who cares if you’re truly interested! 👌🏽
Did I just spent 1:35h watching failed engine autopsy? Full-length movie. Wow, man it flew so fast! Great work man! Unfortunately, You are one of the most underrated UA-camrs.
The 'zig zag thingy' on the back of the block is part of the pcv system, hence why the plate has a hose that connects to the intake manifold... the zig zag pattern is a baffle-system to promote condensation of the oil vapors and feed them back into the motor only allowing the lightest oil and petrol vapors up into the intake manifold
gidderman I came here to say this. Honda has been using these baffle chambers on the sides of their blocks for awhile to separate liquid and vapor, and even with such large separators, they still heat their PCV hoses with engine coolant to prevent condensation.
yes, they only want the oil condensate in the baffle where it is always warm, and will dribble back down into the sump, not the hose, the hose needs only to be carrying vapor to prevent deposits in the hose
+Michel Labonte Thanks for the info. Something I haven't come across before.. Cheers Andy
no wonder!! I was wondering why they were emulating a radiator groove on the block...
1 careful owner...
not abused,needs an oil change...
WTF whats wrong with those people. Saving approx 700$ on oil changes over 75k km and buying a new motor for approx 5000$ instead. Much money saved sir.
+Chris You are correct Chris....but it seems logic sometimes does not prevail or maybe they had planned to sell the car before the engine failed. Making it somebody else's problem?
Hi Andy, thanks for your fast answer. Thats even worse thinking, but you could be right. If thats the case Im happy the original owner needed to pay the bill, hopefully hell treat his stuff the way it should be treated from now on.
By the way: Just found your channel and I really like your videos. Very detailed. Subscribed.
Greetings from germany
+Chris Gutn Targ!
Teaching fits you perfectly, Andy - I could listen to you for hours.....
Well done, Andy. have serviced hospital radiology equipment for over 40 years and worked on many cars throughout the decades. From my experience, I have seen that when anything is well maintained and kept clean, the operator treats it with more respect than equipment that is not. Operators tend to abuse things that don't work well. Then, they need to replace more frequently.
When we bought our used Jeep, our son (mechanic) said to get an oil change after we bought it, no matter what the sticker said. He made the very good point that one never knows how the engine was actually treated, or when the oil was changed. Now, we know when it's been changed, and can keep a much more accurate record of maintenance for the engine.
KECOG ...or if the right oil was used. I always change the oil TWICE when I buy a used car the first time.
forget the abuse of no oil change...some decent topping up of oil could have saved its life...
Honestly, it's in much better shape than I would have expected!
Good show ol' chap
It's refreshing the way you present your channel..just plain,yet eloquently,spoken...subbed
+herbyverstink Thanks herbyverstink, I'm pleased you found the video interesting. Thanks for the feedback too. Cheers Andy
I saw, with my own eyes, a 300,000 mile Cadillac 500 C.I.D V8 with the factory hone marks still in the bores, I have seen other high mileage Honda engines where you could also still see the factory hone marks, it can and does happen, it all depends on how well you take care of the engine, and how it was made.
Carstuff111 we sell cars and this lady had a Manual 87 Tacoma with 489k miles on it and it was even lifted about 4-5 inches don't know how it survived because when she test drove our cars she was driving pretty crazy
If you still see the hone marks in the cylinder bores after all that time, it's actually a sign that the engine was never broken-in properly. That's the problem with running synthetic oil from new -- synthetic oil is so slippery that the rings and the hone marks polish-down before they finish grinding each other flat, so the rings never quite seat properly. Those hone marks allow just a tiny bit of leakdown which wears-out the oil faster over time. Engines should be run with cheap oil for the first few hundred miles, and THEN switch to synthetic for the rest of the life of the vehicle.
130k mazda 6. Did plugs, i am a nerd so i have endoscopic cam, goggles. So i saw yhose “hone marks” and thought my engine was screwed. In a panic i went on the net only to see all four cylinders look new. I have been giving it synthetic oil changes every 4000 miles. Drained oil was deep brown, never black and ussually within 1/8-1/4 of a quart from 5.25 qts starting. I am so impressed with everything except pcv placement making intake service part of pcv.

@@spoada don't forget to service your blinker fluid lol
@@deusexaethera ya this is a load of garbage. Most break in is done at factories these days and, when not, they come with break in oil.
46000 miles without an oil change yikes
Excellent video mate, found you via a recommended watch under a regular car reviews video. Found it enlightening, and informative without feeling like I was being talked at. Can see you put alot of time into this, not to mention editing. Excellent teaching mate, can't wait to see more!
+JS Thanks JS, appreciate the feedback. Cheers Andy
My brother had a 1999 Subaru Legacy wagon for 6 years that burned oil as long as he had it so he got into the habit of checking it and topping it off every month. He had to make a few extra trips than usual due to work/life in general and seized it a few days short of his monthly check. I got a call from him saying within a mile it was fine, then sounded like a tractor, then stopped completely. After driving 45 minutes to pick it up it was still hot and when I removed the dipstick there wasn't a drop of oil on it. We filled it with oil and it shook and sputtered, but managed to make it home on two cylinders. That 2.5 was a trooper.
Lack of maintenance, unfortunate as it could have probably gone much longer.
+Powerstroke 6.7 Most definitely would have lasted a few more years. Servicing is critical. Thanks for your feedback. Cheers Andy
It could have lasted a million miles in the hands of the right owner, I'm sure.
+Andy Mechanic next time try a Cummings.
+Michael Chevreaux If one comes my way...for sure :-)
We have the money, we have the technology.
WE CAN REBUILD IT...
I had a friend who worked at Hi Lo auto parts and he had a Toyota Corolla. This was back in the late eighties and he had never changed the oil in it. It had 58,000 miles on it. He was complaining of it running rough. I had him buy a case of cheap motor oil, three filters, two quarts of engine flush and 5 quarts of decent motor oil. We flushed it twice and then did a normal oil change. He was so amazed when it ran nice and smooth after that. As Bill Engvall likes to say, "Here's your sign."
I can't believe I've never untill now spent an hour and a half watching some guy strip a motor.
I love how women advertise their cars for sale as "female owned" as if that's a good thing. Nothing will make me pass faster.
Shhh.....dont tell anyone they will stop advertising it as such
@@malvasia17 That's rare though. Though I'm teaching this to our daughter before she gets her license. I'm going to let her drive one one of my Porsche's until the OBD2 says she misses an oil change by more than 250km. At this point I'll take the car back and make her work at a quick lube for 12 months if she wants to drive it again.
This is serious shit. Don't care if you're a gentleman or a lady, learn to take care of your shit.

Bottomline: take care of your engine and change your oil+filter regularly. Don't be a cheapskate and do your ride some good.
Great video, by the way. I like the way you take your time to explain matters. Being an engineer myself, I really appreciate your hands-on approach and I also learned quite a few things tonight.
Sven Schwingel i
Great video! I have been watching lots of videos regarding engines and automotive repair and maintenance and I find your approach refreshing. Very good and detailed information. As an amateur, curious and enthusiast I felt so happy to have come across this video that I subscribed immediately. Keep up the good work and positive contribution to the world. :)
+Fábio Malhão Thanks Fabio, it's people like you that give people like me the enthusiasm to keep doing this. Thanks for your honest and positive feedback. Cheers Andy
I just want to say you've done an excellent job presenting this video.
Very much appreciated.
With regular oil change this motor would have lasted 300 000 kms
ANYONE ELSE but me also enjoy the "Myth Busters" series on HOW much abuse engines, i.e. sugar in gas etc , can take?
+Michael Chevreaux Definitely :-)
Flipping great video Andy. A real eye opener to how the oil works around the main components
First post of yours that I have seen, very good in depth strip and excellent discussion of where it all went wrong. Thanks.
Was the oil light on or had the oil level not gotten that low?
+David Brown Oh I'm very confident the oil pressure light had been on for quite some time! The driver just ignored it!!
Thanks Andy. I really enjoyed your teardown as I drive a 2007 Honda Fit/Jazz with 135,000 miles / 217,000 km on it. I do extended oil change intervals with synthetic oil.
+David Brown Awesome David, many thanks for the feedback. Am pleased you enjoyed the video. Lots more to come. Cheers for now. Andy
On a Jazz and most cars the "oil light" is activated by low oil pressure, not low oil level.
Either case if it come on, at least some damage is already done to the engine. :-(
I've seen to many owners like the BAD example on this video.
Once while riding with a colleague the engine was shutting down on stop and go traffic (idle) that happened some 6 times until we reached destiny just 20km away. Upon arrival I told him to pop the hood....Well I couldn't see ANY oil on the dipstick. The oil light never flickered, I barely save that engine. ;-)
Another colleague ask me if I could check "a light" on his car! Turns up it was the oil light. Anything below 2000 rpm the light was dead on. Similar story, no oil...
Sold my impeccable 70.000km original Ford Fiesta, Zetec engine, to my brother in law. At 105k same story, car went to scrap yard. Because he didn't check the oil. :-(
I can report my partner with exactly same year car/engine sold it with 300k the engine was still perfect. But he checked the oil. :-)
@johnny smit I had an old mazda 323/Familia where the sump plug dropped and the oil pressure light came on, but there was a supermarket nearby so I plugged it with a rubber glove and refilled it with some cheap oil to get it home. After changing to better oil again it seemed it was unaffected. But I guess that is different from the oil pressure triggering from not changing the oil for ages.
Yikes I change my oil with full synthetic every 6000 km(3750Miles) on my truck with top quality filters. An engine is too expensive to cheap out on when it comes to oil and filters. Always change oil when it is recommended or slightly sooner if you push your engine hard.
+MrJimmyPayne Great comment Jimmy. If it's not a normal usage then service intervals must be done more often. Thanks for your input. Cheers Andy
The transmission is actually more expensive than the engine nowadays. Engines are pretty cut-and-dried, all the complicated stuff is done in the software now.
Years ago a woman came into a repair shop I was at and said her van was running rough. The mechanic took a quick look at and asked when was the last time she had put oil in it. She had a puzzled look on her face and said never. Long story short, she bought the van brand new two years prior and never even checked the oil. It had 29,000 miles when it finally died from lack of oil.
So many cases of this out there. Such a shame when a little more time spend by the sales person would have educated the lady as to what needed to be done from a servicing perspective
Thanks for the story.
Cheers Andy
Absolutely fascinating!! A clear testimony to Honda engineering! I'd bet you could crocus cloth the journal surfaces put in, new rings, bearings, and high volume oil pump and you'd get another 100 to 200k from that engine. (Not that I'd be crazy enough to spend MY money to do that!) Absolutely agree that a low-mileage replacement was the wise choice. Thanks so much for sharing this story. :-)
I hope we get tailpipe emission testing for WOF in NZ someday soon...hopefully it will encourage people to service their cars properly and get the stinkers off the road :)
Shut the windows and put the AC on recirculate. Keeps the exhaust smells out and the fresh air in.
Simon D what about the car community
Drive in NZ quite often and dont notice it riddled with poorly running vehicles
+yarpos It's not just about the visible pollution. Many of the older cars would never pass an emissions test now. It's getting better now though as there are less 80s and 90s cars on the roads now.
Andy
Add oil?? - mine hasn't use up the last oil yet - and that was 50,000 miles ago! :D :D :D :D
Then change it. Drain old - top up new. Or do you want dirty oil that doesn't really lubricate the engine anymore?
Edit: just cosluted about when manufacturers advise to change oil, and when my dad changes it.
By the book company requires you to do 9'320(from kilometres, I'm from Russia)
My dad does it every 3'728 to 4'970.
My god, you're behind an oil change...
Why? Because there are other factors than just oil being there. It takes up matter from engine, small metal particles, it generally becomes less effective in the chemical department, and because of that it loses the lubrication ability.
Just kidding ;)
Not a funny joke. Work on your humor.
Lol!
SilverDiamond Maybe you should work on your humour detecting. I'm an Aspie (aka very literal thinker) and caught the joke right away, quite a good one at that!
Popped up on my recommended, watched it all and subscribed. Great job bro
Cheers Darren, pleased you enjoyed the video. Welcome on board. Cheers Andy
I've just watched a 90 minute video without skipping a minute, unheard of!
You have a very easy voice to listen to and great presentation style. Nice editing as well, subscribed.
I can vouch for Honda quality as well, a female friend of mine drove her CRV into the ground at 270,000 km, I would often add a half litre of oil into the engine to get the level back onto the stick, and it wouldn't hold water if the radiator cap was done up fully, the coolant would just disappear into the engine somewhere. It never stopped due to engine mechanical reasons. It would still be running today if it wasn't T-boned at an intersection.
Personally. I change the oil in my car as per manufacturer recommendations. (every 15k, so in the two years i have owned it i have had it done three times).
you can do it sooner, but just treating your vehicle correctly you can increase the longevity of oil filters and oil itself.
Btw. when i had my last oil change done i checked the dipstick. The oil was still the right color and well within right levels =)
(did not add a drop of oil in that 15 000km)
Really interesting thanks. I wonder if this engine would have been fine if the oil were a good synthetic.
+metallitech Cheers. Pleased you liked it
No, it wouldn't. You simply can't do 70K km without changing oil, regardless of what it is.
Actually, I reckon you'd have been able to quite easily achieve more than double the mileage before the engine died. Not down to quality of oil (although a good synth would help) but simply by not letting it run low in the first place. As mentioned in the vid, the primary cause of the failure has been lack of oil. Firstly everything has run way too hot with low oil & has caused heavy deposits to form, also the viscosity of the oil will have been affected by overheating it & causing it to break down chemically. This has then led to the mechanical failures we saw due to over-tight clearances (heat) and lack of lubrication, creating a domino effect of bearing pickup, extra heat, less oil gap then going forward to increasing clearances, lower oil pressure, crap in the strainer, even lower pressure and eventually complete failure of the plain bearings due to fatigue and melting.My personal opinion, a little jap engine like that would run pretty much indefinitely on just oil top-ups, at least until the filter became clogged enough to open the bypass and allow crap through the bearings, then it'd probably go another 5k maybe before ending like this one did.
+dan mackintosh An excellent summary and explanations Dan, Thanks for taking the time to write such a detailed comment. Really appreciate your input here. This is exactly what I encourage with my channel....collaborative learning. Cheers for now. Andy
I had a Honda Odyssey come into the shop once with the oil pressure light on; it was bought brand new and driven 80,000 miles with no maintenance whatsoever. I drained a few tablespoons of black muck out of it. So I could absolutely picture 75,000 km before engine death, especially with how splendidly made Honda's engines are.
Hi Andy! I had this video in my recommended list. Always had an interest in automotive theory and watch a lot of channels like Engineering Explained, ChrisFix, as well as car reviews and builds/modifications. I wasn't expecting to watch the entire thing but I I'm glad I did. I even paused it when I had to step away so I wouldn't miss anything. I have always wanted to do an engine teardown just for kicks to see all the inner workings. Watching your video was great and I feel like I would have followed the same path you took. There wasn't a shop class in my high school but I wish they did and they had a teacher like you. Cheers!
+Terrooks Thanks Terrooks, pleased you enjoyed the video. Yes, strip downs are fun, seeing how the 'story' unfolds and reaching the conclusion of 'who done it!' - finding that primary fail.
I enjoyed teaching very much but when the job with Yamaha New Zealand came along working as their Motorcycle Technical Advisor I couldn't say no!
Cheers for now. Andy
Cool music good video gracias man
+Carlos lopez Cheers....it was Google that sent it to me via their Google pics. They made the original video compilation and put the music over it. I made a new intro earlier this year bet felt the music was just right so kept it :-)
It's a forensic autotopsy
I don't get why people decide to be stingy to save a few buck on oil changes. I change my oil every 3-5k depending on driving conditions, weather, and usage type on my suv. If I'm towing in hot temperature for extensive period and I'm in bumper to bumper traffic. That oil is getting changed at 3k. I change my transmission, differentials, diffs every 30k. I did my first complete drive train fluid change at 15k when the truck was new. I believe when you tow and use your vehicle in stop and go, especially if one has a 4x4 or an AWD set up, a new transmission will tend to have microscopic shavings that pile up and eventually may damage the clinoid or grind against other gears.
I could watch these all day, Thanks. Very educational!
46,602 miles, for anyone who wants to know what that is, converted from kilometers.

I bought a jazz was told by the previous owner that the oil was changed recently close to his sale of it to me, So I trusted him I didn't change the oil for another 10k, the oil level was always middle and car ran ok, was getting 39-40mpg with careful driving, noticed some oil spotting on parking one day, looked underneath realised it was leaking from the end of the oil filter, made me realise he must have been lying about the oil change the filter was generic and was as old as methusalah it was leaking from rust!, determined to change oil & filter and went for a magnetic sump plug, researched the oil.
Bought the best oil spec body rated oil for the car I could find- 0w-20 spec Kerax fully synthetic ACEA A5/B5 and ilsac FG5 rated oil £22 delivered much recommended for jazz owners, bought the best oil filter for the car I could find after looking at many tear apart reviews, The french Perflux manufactured genuine honda part £11.00, almost twice the area of other compatible filters, installed a magnetic sump plug £5 to lure any magnetic particles to the sump drain and keep em there(yes i know theres allot of aluminium which isnt magnetic in the engine) anyway, found a mechanic who was ok with installing said parts I purchased (much harder than you think, mechanics hate using customer parts, many were obstreperous over the phone) the mechanic who was ok with it charged £20 for the oil change & fitting the filter etc. on similar journeys to ones I was driving before I just got mpg of 51.6 mpg!?!?! so i Literally gained about 9mpg for £57 - by changing to really good oil and a filter of a high quality? the magnetic sump plug is probably a bit gimmicky but it doesn't harm. Moral of story - change your oil and keep it topped up, its the least you can do for the engine is to keep it happily lubricated with the best stuff.
Really good example of how good servicing pays off both with immediate savings and in the long run too. Many thanks for the feedback & taking the time to post. Cheers for now. Andy
Mark V didn't have ramps, was in a hurry, kerb wasn't quite high enough could get underneath to diagnose but difficult working room, the oil filter was on so long it looked welded on, the oil filter tools - rubber strap, wrench, chain style wrench, torque wrench for sump nut etc, I would have needed etc will have added more cost than £20, due to the filter being rusted on, looked like I could have crushed it getting it off, leaving the threaded part difficult to extract, if ballsed up, car then not drive able - to a mechanic, chose to pay £20 to a garage where a guy had full hydraulic ramp, full leverage, better tools and disposed of old oil, next change I'll do myself knowing for certain it's not welded on.
Also what might have taken me 1 hour+ inexperienced, in cramp quarters with not best tools, took mechanic less than half that I'm sure. But your right in principle, I should have still Changed my own oil. Additional experience post the changes is telling me, driving the car away from the garage it was different almost giddy with zesty energy in a way that was noticeable, now the oil has bedded in, my suspicion is the mpg gain overall maybe more like 7mpg long term till the next change, I guess the oil property's change over time, and fresh 1st week after change is the engines best scenario oil wise.
+beingatliberty Sometimes you have to cut your losses when you know things could go terribly wrong making a simple oil and filter change turn into a nightmare....even worse if you rely on the car as your daily drive. Good call :-)
Now it's done, so be it. But when getting a car that was neglected oil wise. I always prefer to do a few "quick" oil changes, 1k to 2k apart to "wash" the engine. After that get back to the routine intervals.
Upon removal of the valve cover for checking the difference is outstanding. ;-)

at 75,000 kms i would have done 15 oil changes already if it was my car
If it was a diesel engine, yes. Otherwise no.
Changing your oil _too often_ does not improve engine lifespan. Until most of the detergents and stabilizers in the oil are used-up, it will perform exactly the same as brand-new oil.
@@deusexaethera For an older diesel engine it is important to change oil often. Especially for cold and urban short cycle driving. For A gasoline engine it's not so critical.
@@deusexaethera so just topping off will be sufficient for the entire lifespan of the engine block? As you add "detergens" every time ?
@@N-e.o: No, because topping-off only replaces the old oil that leaked-out or burned-off. The oil that _doesn't_ leak-out or burn-off will continue to age and become less effective, and will need to be drained and replaced eventually. I suppose _hypothetically_ if you have an engine that burns a quart of oil every few hundred miles, you could just keep topping-off the oil forever instead of completely draining and replacing it -- but in reality an engine burning that much oil will be contaminating the remaining oil with a lot more carbon than normal, causing the remaining oil to age faster than normal. So no, there isn't any way to escape from needing to change the oil on-schedule. All I was originally saying is changing the oil _more often_ than required doesn't give a meaningful benefit.
Oil change? What's that? LOL
