Why the Chrysler World Engine is a Failure 

Usually it’s just a lawnmower or leaf blower but literally demolishing their own house just to disrupt your filming is serious dedication.

The reason Stelantis uses so many different size fasteners is to help even out the wear on all your tools.

No joke...I've been daily driving a Caliber with this engine for the last 11 years so thanks for doing a teardown of one!. Aside from a marginally common issue with the intake runner flaps failing the World Engine really doesn't have any major mechanical issues. It's not the fastest engine nor the most fuel efficient but it HAS proven itself to be pretty reliable. Also FWIW the World Engine was co-developed with Hyundai *and* Mitsubishi. They all share the same block design but each company designed their own cylinder heads.

That engine had infrequent maintenance and lived in the salt belt. Probably had several miles left. Not a bad engine.

Interesting way to clean the rain gutters out 😁

Love your vids. And your technical explanation and description. Keep them coming.

I've had a few different first gen Mini Coopers (Mopar engine) and it's pretty common to trade out the weird stamped metal idler pullies with the plastic ones from this engine, especially when going to a smaller supercharger pulley because the larger plastic idler lets you run the stock belt. The first gen BMW Mini engine is actually a Neon SOHC 2.0 with reduced bore, bore spacing, and a timing chain rather than a belt. I had way more fun turning up to Mopar events than BMW ones!

Love these teardowns - to add, the World Engine was a three-way design with Mitsubishi

I'm jealous of the nut and bolt assortment you must have by now.

Another great video that moves along at a smart pace. Very well done!

Is your neighbor doing the architectural equivalent of your teardown videos?

Long time subscriber! Glad you’re still producing content :) And dude I KNEW YOUR channel would grow. I feel very happy for you.

I had a co-worker with a caliber. One year, it needed $500 of suspension work. The next year, it was $800 to pass inspection. The following, it needed $1200...that's when he traded it in for a Mazda 3. Design wasn't the only issue, quality wasn't there either.

I find it helps during original assembly to first dip all the bolts in seawater. Eh, I guess it looks like a decent enough budget engine. Except for those bolts, that is insane.

Well done, my brother. Quick and to the point.

The Mitsubishi 4B11 variant has few changes, like no balance shafts. The Mitsubishi one is a good one, taking into account regular oil changes.

Great video, fast and to the point. Keep it up like this, please do not change.

You should do the 4b11 too, the world, theta and 4b11 are the same design it would be cool to see the differences

😂 Just after you said that they’re “pulling a Volkswagen” with the fastener sizes, I get a VW ad talking about their “quality German engineering.” 😂

"And here we have a mandatory engine hook, for when these fail and have to be taken out." Bruh!!!🤣🤣

I had a 2007 Dodge Caliber with this engine and it ran great. I sold the vehicle before it had too many miles on it as I was concerned about the longevity of the CVT transmission. Suspension and brakes were a problem for me. The tie rod ends had to be replaced at 20,000 miles (I have never seen this happen before) and I had to replace the lower control arm bushings about a year later. I only had about 30,000 miles on the car when I noticed that the brakes would start to squeak when I backed out of the garage in the morning. I had the brakes serviced twice and the noise stopped for a few weeks after each service and then returned. I got annoyed one day and bought a complete set of drums, rotors, pads, and shoes. I installed them at home and the brake noise disappeared, proving that sometimes the parts cannon will get the job done :-). I special ordered my Caliber and I liked driving it, I only wished that the quality was better. I rarely buy American cars as I have had much better luck with Japanese vehicles. Thank you for this engine teardown.

I watch allot of your videos its very interesting ,and the way you present it its very nice and straight to the explanation on what ever topic youur knowledge ,good work thanks

You can really feel the Mopar love in this one

I dunno, seems to have held up well enough considering high mileage and clearly less than stellar maintenance, these engines have their issues but they aren't failing left and right, they're pretty reliable all things considered. It's just everything else attached to it and the vehicle that falls apart.

Love your videos... your brother is going to have hard time figuring out which side of his shirt is the clean one now!!

I bet your brother doesn't enjoy watching your videos very much. Thanks again for another very informative video. They really made me change my mind about buying many cars.

Chaotic tear down videos are the best

Makes me realise how beautiful my old engines are (Mazda FE and BMC B-Series...everything solid, everything serviceable.)

Thank you for your videos dude they are amazing

My parents have a 2007 with the 1.8 It's been very reliable for them, only issue they had was the PCM crap out on them a few years back.

Great demonstration ❤

NICE .BRO LEARNING A LOT FROM YOU!!

love your videos. would a teardown of a buick 3800 SII that were in the 2000s impalas, park avenues, and monte carlos be interesting?

You are like a teacher who grades manufacturers on their design and production work. It’s AWSOME!!!

I work on these pretty regularly, the coolant housing on the side of the head is what fails the most. We see a lot in for overheating due to those housings leaking from the gasket flattening out and the housing warping. Aftermarket parts are terrible plastic quality, we only use dealer ones now and they're currently 2 weeks back ordered. As long as you keep coolant in them, change the oil, they'll do 200,000 miles or better. The transmissions normally attached to these and the vehicle it all goes into are unlikely to make 200,000 miles.

Knock on wood but I have a great 2009 caliber sxt with 120k-I bought it in 2010 used and it still works flawlessly today.😊

Brilliant teardown!

Can you do the Mitsubishi 4B11 variant of this engine? It would be cool to see how different it is from the other World Engines.

I had a Caliber with the 2.0L World engine. While this was certainly not an era of quality for Chrysler, I don't think I'd give much blame to the engine. Decent horsepower for its size, but my theory on that is that the cam adjusted to produce less torque and prolong CVT life. Result is iffy fuel economy, but it wasn't bad to drive. What was definitely a tragedy concerning this engine is the sound. Winter start up was atrocious, and the exhaust "note" was about as pleasant as a straight piped Civic. All of the legitimate problems with the vehicles involved low quality metal in the suspension, and the disaster that is the electrical system. I really liked the design of the interior. Yeah, cheap hard touch plastics, but 4 cup holders in reach of the driver, two glove boxes, and a power inverter. Pretty cool.

That engine actually looks pretty decent 🤷‍♂Biggest surprise is they have a bed plate...but don't use it to hold the lower main bearings. That seems like a very odd choice, giving up lots of lower end stiffness. Everything else looks equivalent or better than other 4 cylinder cars of mid-2000s+. I like the cam-on-bucket valvetrain, too, very simple.

Engine tear down and house tear down in one video. Perfect world.

Wow, I've remodeled some houses before but never used an excavator, seems its done different on the north side of the pond. Nice bolts, access was in your favor. Somehow I get the feeling you have less than stellar feeling about that throw away engine except that the vehicle itself is prone to scrap. Great review! Also glad to see snow as I hate to keep it all to myself on the south side. Time to see what Chef Safi has cooking! Thank you for another education as to what to stay away from.

I always dreamed of owning a company where it does nothing of what this industry does which is ultimately to not just what the customer wants but actually needs. This engine is a good example, of just corporate carelessness and leadership mistakes they burden onto you with. My idea would be to make a modular frame instead of unibody. This would allow platform releases to go by the decade and when a customer wants to buy again they can instead option to have their car refurbed or even upgraded to more modern components for that platform. Played around with it alot in Beam NG and Automation/Blender and i'm actually serious about making a spaceframe to conceptualize my idea. My friend once wanted to fly for Red Bull and so he worked hard training new people how to fly, one mega millionaire student noticed his effort and hired him on to fly for his charter and teach him how to fly his new HondaJet. Half a decade later hes rolling around like a boss in a MXS in Redbull AR camp (top of class too). So who knows maybe someone around will admire my concept and it'll kick off but by preference i'd like my first build to be with my own cash so the weight of mistakes carry more discipline in engineering. Plus should I take off with my idea, I've wanted to build something rugged, but also elegant. Standard with each model too is EMP shielding and an option for CBRN military grade sealing w/Oxygen supply. Windows and doors will be bulletproof up to 5.56 (there's cheap tech that can achieve this). Basically a car that looks nice, is reliable enough to consider an investment saving with the modular design, and can survive whatever mess these idiots running our governments are getting us in. Honestly I think given the current state of the industry, this would make a killing in competition and bring standardized safety more complacent with our present environment (crime, etc). Cause people can make one large finance investment, but not have to repeat the cycle and be free of any loan for a bit, then when the time does come they can diversify with more cost-effective solutions that I would offer. Would also create a good relationship with the customer which if it satisfies them, also creates a cash flow for you as a continued patron. I'm also a freak about making solid products, a hill I would NEVER die on unlike most of todays industry. Not while I'm in charge.

I had a dodge caliber for several years, had very little issue with it or the engine. Maintenance and some small issues were easy to diagnose and fix

2.4 are great engines ,have four of them in our family with lots of miles and no issues ,not really sure the point you were trying to make if any !

Great watch and listen..Thanks..

2:26 just love the way you just were like "btw neighbor house demo plz ignore"

This engine is a rough but reliable workhorse that was put in millions of cars for about a decade. I got my own past 210,000 miles before it started burning oil and it still runs fine with just a little extra between oil changes. Don’t believe this clickbait title these engines are just fine. Any car that has this engine will fail on you well before the engine does

So looks like the internals are designed OK, but the peripherals are not too good, better that then the opposite I suppose 🙂

I think I have one of these in my Kia Spectra 😅 It's never failed me and I've always abused it but hey if it doesn't wanna fail I'll keep it.

A F150 forum member drove a Jeep Compass with this engine over 400,000 miles and he said the engine was still running fine with no oil burning. But the body rusted out to the point he had to give up on it.

At times, using a thinner fastener is better than a thick one. Using one that's as thin as possible will give you better tension. Think of wrapping a oil pan with bailing wire vs. bungee. The bungee will be flexible & always give some tension vs the ridged bailing wire.

You need to get ahold of the Chrysler 2.7 and 3.7 V6 engines and tear them to bits so we can all laugh at how utterly rubbish they are.

Seems like solid build engine as you disassemble ot more and more. If only they didn't cheap out here and there.

Some days I feel just like your neighbor.

Waiting for that moment you start assembling the engine you disassemble

I'm glad that engine went to some good use. I'm pretty sure you bought it from me. CHEERS !

Is there a link to the house-teardown video too?

Why use the word failure? I'm no fan of modern Chrysler but cannot see anything seriously wrong with the design of that engine and you said several times it was high mileage.

fail often? I'm confused the one i replaced at the Mitsubishi dealership was 1 because they had no oil in it and I didn't even replace one at Chrysler but i did do 3.6l head gaskets and 5.7L hemi engine on a brand new jeep Wagoneer. in my eyes those engines are basically indestructible not the fastest nor highest quality but it's a mass produced economy engine

Looks like a solid simple design. All the plastic is the weakness.

So, why is it a failure ? The bolts ?

I loved the video. I'm from Brazil and I'm thinking of buying a 2017 jeep compass equipped with the 2.0 engine. The manual contains only two revisions, one at 12.168km in 2018 and another at 24.131km in 2020. Currently the car has 40000km and the 36000km revision is not included in the manual. Would you recommend the purchase anyway? Thanks for the content.

I miss the 1960s period , it was a great time to be a gear head. Engines were not as fuel efficient but they were simple and rugged even the worst of those years was better than any crap made today . Practically any engine of that vintage with modern ignition and aftermarket injection system are the way to go in an older restored car / truck ,the hell with the gadget filled cockroaches that people call cars in the past 3 decades.

What line of 4 or 6 cylinder engines would you recommend for a simple, bulletproof design?

You really never said specifically why this engine is not a good one in fact you made several statements that point to your lack of basic engineering skills. I don't see anything other than lack of oil changes that caused problems for this engine.

Grandpa wasnt doing his oil changes on time 😂

Never seen someone so offended by plastic parts (not broken on an engine that has outlived the vehicle) and the concept of using an appropriately sized fastener, even when that means more than one size bolt is used. I took a plastic timing gear out of 1971 400 Ford last year. Updating the cam... timing gear still going strong. Turns out all the outrage over those plastic gears was much ado about nothing.

How much longer before we start seeing plastic blocks?

Excellent choice of tools. Milwaukee makes quality stuff. We have a few Milwaukee impact wrenches and drills in our shop.

My mums 2007 jeep patriot has the 2.4 version of this motor and it's still going strong 16 years later

Your a fast worker, your boss must be proud!?

at least this engine has a proper timing chain. VW uses a bicycle chain

I have one of these, they are tough little engines, besides replacing the pulllys and spark plugs, never had a problem in 15 years. change the oil once in a while and don't over heat it. Revving little engines too, 6,750 redline.

Your neighbor is very funny~ love it~

"Oh my God, more oil" 😂😂

I see no failure but a well worn engine. At least the water pump is driven from the serpentine belt and not from the timing chain.

Thanks brother 👌🏼

My little Dodge Avenger has 200k+ miles, this will definitely come in handy in my rebuild. Plan to fix up the old Engine with some TLC because it is my first car and I’m not ready to say goodbye

Speedkar, can you do the Nissan Infiniti VK50VE? It's an ultra rare and unique engine. It is essentially the V8 version of the VQ37VHR and I've never seen it modified or boosted before! It puts out just under 400 HP and was used in the LMP3 race care, but only ever put into the FX50 and early QX70 production models. I would love to watch you tear that engine down.

In a odd twist the neighbor was complaining about impact wrench noises on his home demo video.

You must have some bias against Chrysler. There are literally millions of this little engines still in service with relatively few failures. I owned one (a 2.4) in a Chrysler 200 and it had over 200K when I donated it to a family member. I drove the car every day like I stole it and the only issue I had was the oil pain leaked and had to be replaced for a whopping $30.00

Hi great videos. Thanks from dubai.

Should get your hands on a 5.7L Hemi Eagle. They're everywhere and have been produced for years. You could do a teardown and show the common problems and such.

Another day, another video. Boy is your brother in law going to be ticked off when he finds all his clothes missing! 😆🤣😂

Troubling trend of plastic parts used in an engine. Does this have iron-sleeved cylinders?

Thank you ❤️

I've seen a 2007 Dodge Caravan with the 2.4L 4cyl. It ran on 3cylinders for the longest time and diarrhea for coolant! I did a tune up and new ignition coil pack it ran on 4cylinders again! How has it survived for this long is insane!!!

Yeah, but... Are you gonna rebuild it?

ARE YOU GUNNA REBUILT IT?

Think you could get ahold of a 5.7 hemi?

there's a guy on the other side of the fence trying to do a house teardown video and you are disrupting him ;)

First time i have heard that rusty bolts are a metric for quality….. guess what we salt are roads up here in southern ontario, Calibers haven’t been made in since 2012 still see the occasional one still running around most seem to have little to no rust.

The question I have is why is your neighbor demolishing their house? And should you be worried that you will have to do that too.😊😊 lol

Interesting take here. I actually think that the world is a fantastic engine. For the sole reason that it is made so affordable. The costs they save in engineering are put back into your pocket. And I regularly see cars with the world with 200,000+ miles on them. My girlfriend drives a 2008 Jeep Patriot with the world engine and she has 185,000 miles. And it’s been great. The engine is also incredibly easy to work on. The fastener sizes are a pain. But other than that. It’s a very simply and strong engine.

So funny.. you took this engine apart in 18 mins and dude from i do cars takes 32-35mins.. i like your version better man. you got to the point. 💯

Not sure why you seem surprised and/or disappointed with chain guides being made of plastic; I reckon you be hard pressed to find a modern timing chain engine without and there are plenty of examples of them being durable. Also examples of them being total (BMW) crap of course 🙂

Think it's probably better than my Subaru 2.5l. Much easier to work on, I'd say.

This dude 😎 has the best videos I had to subscribe I'm a true gearhead I went to Universal Technical Institute in Sacramento California wear I earned my gearhead badge.

Would love to see a teardown of the 1.4 MultiAir Turbo Engine. Now that was a failure
