I RUINED IT! Tearing Down A "BAD" 2.0L Chevy Cruze Diesel The Wrong Way 

That 5 point fastener means someone is mad they're not designing stuff for Apple.

I used to build these cars in Lordstown and I was there when they launched the Turbo diesel. Just a little nugget, the diesel cars came down the line with a red manifest taped to the hood indicating diesel, regular models had a white sheet. Diesel car all received heavier trim pieces, thicker hood pads, thicker firewall padding, thicker padding under the carpet, behind all the trim pieces. and under the rear seat. They also received more body sealer inside the spare tire well from the body shop. I'm pretty sure they also had a thicker head liner. All to help with the extra noise from the diesel.

I think Eric was feeling a lot of remorse for using that impact gun on the valve train. Its okay Eric! Its okay!😀👍

This engine had a bad waterpump. The waterpump on it was brand new the waterpumps on these engines have a habit of seizing up than the belt will rub against the cover until it snaps. Thas why the rockers were broken. I think they did a timing kit on it to fix it but it didn’t work. This is a common problem of this type of engine what actually is a fiat/alfa romeo engine that gm had the rights to manufacture.

This is a Fiat 2.0 Multjet engine for sure. very good engine indeed. They design the rockers to do that instead bent valves.

The engine is very normal here in Europe. It is actually designed and build by FIAT. It has a very known problem that kills it. The O-ring between the sump and the oil pump becomes hard and leaky. It sucks in air together with the oil and when the oil light comes on, it's already too late. The bearings on the crank are finished. A known problem in Europe and used engines are sought after and expensive.

"there's nothing wrong with this engine" As it vomits rusty water You sir are a professional used car salesman

Oil pump screws - "manual impact driver" Works great.

To undo the loctited fastener, apply reasonable torque on the edge of stripping and hold the torque. Hold. Hold. Sometimes it can take up to a minute. And all of the sudden it gives. That’s because polymers in the thread locker are pliable. They will resist sharp forces like vibration or impact wrench, but will give at the steady force.

15:08 Senior Design Engineer at a major OEM here. That fastener decision was likely not engineering, it was Production and/or Procurement. Designers aren't in the business of perpetuating retardation of that type.

I love my 2014 LUZ Cruze. Just reached 100k miles, I can get over 600 miles on a tank of fuel (easy 45 mpg highway) and my best 50 mile average is 59.9 mpg (flat road, no wind, no drafting). I've made it from Detroit to NYC on a single tank of fuel twice, and Detroit to Asheville on one tank more times than I can count. And the added list price was mostly due to the trim package, the gas engine with the same trim was only about $1,500 cheaper. I plan to keep mine until I die.

Fun fact, the glow plugs on these engines use a M9x1.0mm thread pitch. Something I learned when I went to try to compression test one. The necessary adapter is something that doesn’t come in most diesel compression test kits.

My Vauxhall Insignia have this engine, I really love it, mine done 200k and it's still run amazing with no problems, just regular mentenance, them big issues is oil pickup gasket, they are shit, in time it lose oil pressure and kill it, easy to fix with a aftermarket think, except that it's amazing engine ❤❤❤ Good job Erik, I enjoy your teardowns every week 👍👍

Yes! Midweek teardown! Always a treat

If I was your insurance provider id make a deal: Go ahead use the torch anywhere you like but don't ever touch that chop saw (with no guard) again!

About that unique fastener. You can't delete emissions stuff if you don't have the tools to take it off. I'm thinking it was on purpose. Who knows.

That little engine was a torque monster when it was new and running.

I admit I cringed when the impact was spinning the camshaft, but I think it is so cool that you said perhaps it wasn't the best idea, and then admitted it freely as a mistake at the end. It takes courage to admit mistakes in a huge forum like this, and I admire that. But, based on some of the other comments about the water pump seizing (though it didn't seem like it was seized, though the engraving of the timing cover by the timing belt is a sign of that happening) and causing the valve timing to get messed up, the busted rockers (which are apparently a purposefully designed weak-link to prevent bent valves), may not have been your fault. You may have broken a few more rockers in the process, but then, maybe not. I hope you can get some positive ROI on this engine from the good parts. Great video as is usual. Your witty and humorous commentary as well as great information content always assures that when a new video comes out, I'm on it right away. Thank you for doing what you do!

Ray tore down an engine earlier and now you grace us with a teardown. Its a good day today.

The reason that one part had a special fastener is because it's part of the emissions equipment that they don't want you to remove. So they make it so you won't have a tool to remove it .

hey eric, just a quick heads up, there's plenty of euro diesel engines where the cams are hollow and the lobes pressed on and to avoid certain issues they make it so if out of time or similar event will break all the cam lifters in half instead of bending any valve since they are just straight up and down (vw, peugeot, renault, fiat, benz, even hyundai and kia diesel's are like that), so yes, the needle bearings are indeed your aftermath in the pan 😂 a few examples would be peugeot's 1.6 dv6, fiat's 2.0 multijet (of which this engine is born from) and renault's 1.9L FQM diesel all have a "cam on valve cover" in a similar fashion to the "cam tower" you find in other engines (like that toyota 2.5L and the GM 3L LM2) EDIT: in my opinion? this engine is freaking mint, she just needs a service and its basically a 100% builders engine! my guess is that it might had ingested water or hell maybe a flood car...

Those are made to fail rockers. It was probably wrecked before you got there which is why the cam spun. It looks like waterpump crapped, taking out belt, and stopping engine. Engine was pulled after it wouldn't start then got put in the junk bin.

Here in Europe the diesel engines in cars were pretty popular. Due to direct high pressure injection and the use of turbo's they produced a lot of torque and horsepower. If tuned, they had a lot more horsepower and torque. The VW 1.9 tdi for example was a very popular engine and was tuned a lot. It could quite easily be tuned up to 200 horsepower, using bigger injectors and a bigger turbo (and then a remap off course). Nowadays diesels are not popular anymore, because politicians taxed them to death

I have this engine in my Alfa Romeo in the UK. I love it - Fiat are known in the business for making good engines. 140hp, 350ish NM of torque, I genuinely drive it like I stole it and still get about 43mpg (nearly 50 american mpg I think?) I have seen around 70mpg at around 70mph on the motorway when driven efficiently (uk mpg so ~78 american mpg) Also low emissions (so tax is very very low at £35 per year, I used to pay £35 per month for a GT86!) The worst part of the car is the gearbox which actually is a GM part. 🇺🇸 😂Cant take much more torque than standard and they all have a bit of a crunch sometimes if you rush 4th-5th.

14:50 ,its a 5 point torx anti tamper fastener ,need the tool ,its also used on other components in the vehicle....they also used on parking boots on the keypad & bracebar ....you can easily remove those pesky parking boots unless it has the 7 point anti tamper fasteners...but then again i got those too 😁

I let out a little scream when I saw 2.0L chevy cruze diesel I have been waiting for this one Thanks for finding it

This channel is like Blue's Clues for gearheads. I love it. Thanks, Eric! Keep up the good work!

You honestly admitted to doing a mistake any of us who would be just as uninformed might do, Proud of you.

Going back and forth on my locked up engine unlocked it. As good as new. I can’t believe this repair advice actually worked. Thanks!

My boss has one of these. He loves it so much. I maintain it and it has amazing fuel economy.

A Chevy with FPT Multijet 2 engine? Wow. I never heard about this before. In Brazil these engines tuned to 180hp and 350Nm of torque are used in little Fiat pickup called Toro, 3 Jeeps (Renegade, Compass and Commander) and RAM Rampage (Stellantis doesn't sell it in USA... yet)

"The next first thing I'd like to do..." OK, I'm stealing that line. 😂

I LOVE the rare and/or weird engine teardowns. And I like diesel teardowns. So this is double awesome. A teardown to remember. (I also love stuff like transmission or differential teardowns, but I guess you don't get much opportunity for those.)

Was initially uncertain trusting an Italian diesel but now with 306,000 mi on my 2014 Cruze CTD it has impressed me. Except for the horrendous DEF setup, it is a great car. GM must have messed up by building such a good car

I bought a 2.0 diesel Vauxhall Insignia when I lived in UK. Such a good economical car I took with me to New Zealand when I moved over here.

Every RU-vidr: Eric: I made a mistake, so what The world needs more of this.

Just saw Ray tear down a rusty 350 boat anchor, Now you tear down this one. I think the valve train was done before your impact. Nice.

Learning is a major reason I enjoy your videos so much. You are so freak'n honest and self aware and that builds a lot of trust between you and your audience. Once again, thank you for another excellent video!

another very enjoyable episode! Thanks for taking the time and effort to do this!!

Its not locked up, its got very good compression

From online searches this is probably one of the best diesels sold in the US in this era. Far less problems than the Jeep/Ram Fiat Diesel. The people that bought and taken care of them really enjoy the great power and excellent fuel economy. To bad VW ruined the modern diesel market in the USA.

I own a 2017 Cruze 1.6L diesel engine and it gets great fuel mileage (5.1 L/100km as we are in Canada). The torque is incredible and it way out performs our 2017 gasoline Cruze in mileage and torque. The only engine issue we have had on the diesel with 170,000 km (about 105,000 miles) is the DEF injector plugged up and set a code. But resenting the OBD light and doing a few Italian tune ups cleared the blockage. I enjoy your channel.

I really enjoy the mid week videos!. Keep up the good work Eric! I appreciate the effort you make to remove the parts with care. BTW I need a water pump. lol

Great teardown Eric, it so good to see you dismantle and explore a somewhat unusual engine.

Love to see the diverse teardowns. The diesels are especially interesting to me.

I really enjoy this channel because you share the mistakes and the success when you tear a engine down also you do not have annoying music. Thanks for making this an awesome channel!!!

FINALLY! Really enjoyed this teardown since we have a 2014 Chevy Cruze 2.0 Turbo Diesel as well. Unfortunately our water pump took a dump and we aren’t looking forward to replacing it nor the torque converter.

I love your enthusiasm for what you do! "This is the way" 🙂

Well, live and learn, which do do well. Thanks for the treat!

Mid-week episode, love it.

One of the best little diesels ever made. If well taking care of could produce 50 miles gallon throughout its life. My girlfriend had one It went through three transmissions but the engine was still running. I don't remember the exact mileage when she gave up on it but it was in the high 300s

Hi Eric thanks again for a midweek teardown and something a little closer to home 😂 here in the UK it as you know would be a vauxhall 😉 I've had the pleasure of working on several of these over the years and I'm sad enough to actually have the correct socket eg 5 point tamper proof torx 😂 as mentioned before these are a joint venture between GM/Fiat and VM. The cam set up is very common on most small to mid size european diesels the Peugeots have a cam cover/bearing carrier Combo all held together with 33 8mm headed m6 bolts 😂 I've done plenty of those which like this are sacrificial eg followers snap and the cam lobes spin to protect the valves 👍 Not sure if you get the 2.0 Ford ecoblue diesel in the US which I've had the displeasure of repairing several, these are junk eg wet cam belt and oil pump belt which is supposed to last 120k but can go anything from 60k 😔 same thing smashed followers and spun lobes but the cams are pressed into the cover so not serviceable and £600+ to replace. Looking forward to weekends video keep up the good work cheers Matt 🇬🇧

Great job, Eric. Love the honesty.

Quick tip for ya when looking at oil filter media. To better see smaller pieces of metal debris. I will take the piece of filter media after it’s cut out of the oil filter, squish it together like a squished accordion. Then I’ll put a rag around the whole filter media piece and squeeze all the oil out of the media in a vice, drying it. Spread the dried piece of media back out on a bench and you’ll probably be able to see metal debris much easier. Hope it maybe helps in the future! I always love the videos and your work!!

So glad you took one of these apart!!

Love the middle of the week lunch time teardowns!

Great video Eric. Have a great day.

"Progress and learning come from both success and mistakes." I'm sure some philosopher or engineer (probably named Murphy) said that. Great mid-week video. One small problem. I don't allow myself to invoke the "J. Buffet Rule" after a hard work-out, which I had this morning...so no wine, like I usually have during your ever-enjoyable Saturday video. Hope all is well with you and your family!

As always you have made a great video and the diversity is a great thing that keeps the channel interesting and educational as always. Good morning and have a great day.

My diesel Cruze came with an extra rear main seal bolt from the factory in the bell housing. Finally jammed against the flywheel at 150K miles and locked the crank.

It got paired with a really good Aisin transmission too.

I think the fact that the bottom end turned over so easily after the head was removed makes it clear that the valvetrain was damaged before you touched this engine.

What a huge difference between tearing down this diesel compared to the BMW diesel teardown! So simple in comparison.

I would like to tell you how much I have learned from you and your channel. My profession was in Medicine, but I never knew the inner workings of different motors. I watch everything you post. I really enjoy your humor. Like you I am very intelligent, though I don’t like others knowing it. Please keep up the great work, I retired well and if you ever open a patron account I will be in for significant money. Thank you again

Great video. I look forward to the next one.

I always thought the approved method was to gouge the crap out of it with a scraper first THEN try to hide the butchery with wizz wheel that you forgot had sandpaper disc then change to thre scotchbrite pad! 9:38 the more you know, huh?

The Chevy Cruze is based on a Daewoo J platform, basically a GM Daewoo/opel /Holden clone built in Lordstown Ohio.....I actually worked on dozens of these engines back in South Korea, it's in alot of Daewoo & GM Daewoo models

Man I really miss my cruze diesel, but it started puking coolant off the backside of the motor.....had 185k miles on it and got it new

Man, what a complex, unique, engine. Thanks for filming that.

Thanks eric. Great show, didn't think that oil pump would beat you, lol.

I like to see variety in the teardowns and suspense, so this is a good one 👍

Yes omg these are great engines with "a diet " biggest flaw other than the Emissions is the oil pump pick up o ring but there's a aftermarket replacement great engine fuel mileage no mater how you drive it mpg 40 to 50

Thank you Eric!👍

If you fold the filter media up like it was in the filter, then put it in a vise and squeeze out the oil it becomes much easier to see and read the debris left behind.

I've worked on a few of these, and also the later 1.6. The 1.6 Opel diesel in the 2nd gen Cruze, in my opinion, is an even better engine, and it could be optioned with a 6 speed manual. The 2nd gen diesel Cruzes with the manual transmission have only 2 major issues, both of which are easy to fix. Issue #1 is the timing chain tensioner. It doesn't get enough oil flow on startup and when the variable displacement oil pump is in low pressure mode, and also the housing is made of cheap pot metal that wears out. In the US there was never an official fix for this issue. In Europe Opel developed a fix which consisted of a special gasket that held oil in the tensioner, and also a redesigned tensioner. The new tensioner was also pot metal however. They also changed the oil spec from a 5w30 to a 0w20 to get more oil to the tensioner faster. I developed a different version of this fix that used a better quality tensioner and the same European Opel gasket. The 3.0 Duramax in the Chevy 1500s in the US is based on the 1.5 Opel 3 cylinder, which is in turn based on the 1.6 in the Cruze. The lower timing chain tensioner of the 3.0 is an identical shape and size to the 1.6 tensioner, and is made of better quality cast aluminum. Along with the Opel gasket and either the 0w-20 Duramax 3.0 oil or a 5w-30 API FA-4 oil, it's a permanent fix. The second issue is related to the clutch throwout bearing. In the hydraulic line is a clutch delay valve, which is a stupid device that should always be removed because it causes clutch wear. On the diesel 2nd gen Cruze, it disintegrates, sending metal into the throwout bearing/slave cylinder. The solution is to replace it with a high pressure -4AN hose and adapters to fit the quick connects on each end. Mcleod and others make a GM quick connect to -4AN adapter. Two of these and a long enough -4AN hose gets rid of the clutch delay valve and keeps it from sending metal into the slave cylinder. Use a quality brake fluid like RBF 600, etc. Once those two issues are fixed, it's essentially a perfect car. The hatchback especially is exactly what the Golf TDI (09+) should have been in the first place. They are decently fast, get 56 MPG, nice interior, stylish exterior, excellent 6 speed manual. I would love to see a 1.6 Cruze diesel on the channel. Also a 1.2 GM Turbo I3, my mother has one in a Buick Envista, it's an interesting engine and has a nice sound.

Thank you thank you...i own a 2014 cruze diesel. Besides def/dpf issues (in stock form..😉) the only known issue I'm aware of is the oil pump pickup gasket/grommet failure issue.

It's funny the other day I saw Rainman Rays teardown that mentioned Eric and it reminded me he brought me here a while back.

I've been waiting on this video for years!!

Based on the wear in the timing cover, I would say that belt has been replaced already. edit: stated just a minute before Eric states the same.

Snack Pack product placement? LOL Love the videos. Thanks the the mid-week teardown!

I have a 2015 Chevy Cruze with this engine, it’s a 2.0 eco diesel. My personal best is 59MPG on a 50 mile average. 👍

That would be a cool transplant engine for a Chevy LUV, Suzuki Samurai, or something similar.

Thank you for another great video Eric! Looking at the condition of the engine (spares in the sump, etc) having the camshaft spun by an impact would have been the least of that engine's concerns. Just save that move for the truly dud engines, we can't wait for your next video :)

Mine got 275 000km. So amazed at the part quality and as a mechanic I like the "cam in valve cover concept"

You need a JIS bit for the oil pump. Japanese Industrial Standard. Similar to our Phillips bit, but the angles are different.

I owned one from 2017 to 2024. From 30k to 108k miles. Loved the torque after boost lag. Awesome in the PNW mountains. Used WAY to much fuel during warmup killing short commute mpg, but on the open road, pulling down close to 50 mpg with over 750 mile range was it's element.

Good engine design. Thanks for sharing.

One of the few things I remember my grandfather saying, he died when I was 5yo and I'm 68 now, was "if this doesn't work we can always say it should've". I lol every time you say it. Btw, there's a ya sci fi series of books about an AI construct named Murderbot, same sense of humor you give off

i was watching your f20c1 teardown and saw this on the sidebar and was like "oh i didn't know he tore one of those down." then clicked on it and you posted it 43 minutes ago. lol no wonder

They also made a 1.6 diesel for the second generation Cruze. I drove one, but I ruined the emissions components by city driving and lots of idling.

I just bought a 2014 Chevy cruz diesel. I absolutely love it.

I gotta tell ya, Im disappointed Eric didn t show us the Spark plugs, LOL

if your a fan of the long roof cars, back in the day you could get a chevy cruze diesel with a six speed manual in a station wagon body. Unfortunately the station wagon version was export only.

I would love to see you tear down a 2.4 SRT4 that came in the 2003 Chrysler PT Cruiser GT with the aluminum intake. If you can get your hands on one. Great video as usual.

I have this engine. Works great at -20f on cold start. I have mine tuned and get over 500 miles on a tank with mostly city driving. Sitting at 120k miles currently.

Neat little engine, cool teardown 👍

I had one of these and loved it when it wasn’t in the shop for emission issues. Huge fuel tank and 700+ miles per tank.

5 point Torx is used to make things tamperproof. Newer MAF's from GM and Stellantis got 'em. Surprised that Mercedes didn't use them 10 years ago. When you build something goof proof, you're actually building a better goof.

Been waiting for this one, I own one with 120k and runs great. Thanks 👍

Love the BMW wagon :D - thanks for the video!
