Check the coolant tank

[@MiGujack3]

Pray to the head gasket gods.

[@brent3]

Here are some things you can check, next to the oil filter housing there's a coolant junction on the side of the block. Extremely common for the seal/plastic to crack. Also the sensors in the junction o rings can leak. The water pump is also notorious for failing. Not a terrible job, but all the bolts are very tiny and go into aluminum. If I recall they are like 8 ft lbs. I've also had hoses (especially the heater core hoses) rub thru on the brackets ment to hold them. Ironic. My 2013 sonic 1.4t has always leaked something. Once I fix one thing another leaks.

[@mariusgrigoras1655]

[@commonsenseisdeadin2024]

Is this "oil pressure hiccups" a GM issue? I feel like the tensioner not being a ratchet style is the least of your worries if so! The timing chain in this car is simple and with the guides and spring behind the plunger I doubt it will jump timing with any "hiccups" it may encounter. Might have a second of noise on start up but the spring should be plenty strong to keep decent tension until oil pressurizes. If oil pressure drops long enough to collapse the tensioner then you're already fucked elsewhere which who cares if it jumps at that point! And if it fries your chain then I'd be shocked it didn't snap day one!

I rebuilt 5 totaled 1st gen 1.4 Cruzes for my family. Most were purchased wrecked in front for about $3000 at 2 years old with 30,000ish miles and required $800-$2500 in parts to repair. All made it to 100,000 miles, and as you stated at the end they all needed intake manifolds, valve covers, and water outlets. Most needed ignition coils. But the work wasn't too hard and the parts were pretty cheap. GM never updated this engine to fix known issues. All '11-'16's will have the same issues and with enough time/mileage more than once. Driven right the 6-speed manuals Eco models could approach 50 mpg. Changing the in tank fuel limiting vent valve allowed these cars to hold 17 gallons of fuel. 700 miles was the furthest I ever went on one tank. It was the only car I ever need to downshift to accelerate normally at expressway speed.

[@guardrail2897]

My daughter had one. It lived in the shop. It kept blowing intake gaskets. And when the gasket blows out, it shuts down the car. It happened 3 times within 60,000 miles. Luckily, someone rear ended it and totalled it. That was the best thing that ever happened to that car.

I have been working for a GM dealership for 28 years now. The previous of this engine the X10 and 12XE had chain problems. This engine has coolant leaking issues like the waterpump and waterhousing. But I have NEVER seen an engine fail mechanically! Yes the valve cover might leak after 60k miles, but we NEVER had a chain failure , they don't consume a lot of oil either. These engines were introduced in 2014 IIRC and are still in our dealership every day, NO mechanical problems to speak of. They suffer from coolanat leaks like said in the video but they probabably drove it until until it seized to an halt!

[@recoilrob324]

@@tonycj7860 I did the initial oil change on a Cruze Eco and the oil came out black as tar. This was when the 'change oil' warning came on and this owner was a salesman who drove the mountains in PA and Maryland daily...so he was putting lots of hard miles on the car. He wanted the cheapest oil available but I talked him into the good synthetic which should be used on any turbo...then the best suggestion was to use Premium fuel only. He was shocked because it was more expensive...but he'd kept track of every fuel stop so I challenged him to try the Premium and see if his mileage didn't improve enough to more than cover the additional cost. Next oil change the oil looked a LOT better and he was amazed that using Premium actually DID save him money from the better gas mileage he was getting. I'd shown him the oil that came out and explained that the knock sensor retards the ignition timing when it detects detonation. Running 87 octane means that the timing is retarded all the time...which makes the exhaust temperature skyrocket which then cooks the oil in the turbo. Using 93 keeps the timing up which keeps the oil temps down and the oil a LOT happier. Also is easier on all the plastic and head gaskets and in 140,000 miles when I left that garage we'd only had to replace one gasket that started leaking on the oil filter housing IIRC. If you run one of these little turbo motors...please use good synthetic oil and run 93 octane fuel and in the end you'll thank me. :)

issue in teardown was it overheated. that aside, the oil cooler broke on removal, but otherwise this video did not make the engine look bad to me.

Many engines can survive a little overheat but apparently not this one.

[@backcountryrider2643]

As someone who has commuted with both a 6 speed sonic hatch and auto Cruze with this motor and has grown quite fond of them, your closing statements absolutely hit the nail on the head. As long as you can maintain them they’re a cheap little commuter. The 14’ Cruze I’m running now is loaded with remote start and heated leather and I snagged that for $700. Replacing the thermostat and coolant neck with aluminum replacements will remove two faults from these engines.

[@backcountryrider2643]

@@toolwithintention Well, sorry in advance if this ends up reading like I’m rambling lol. Stay a way from 2011 and 2012 model years for multiple reasons but including the fact that on the manual transmission they had smaller bearings for the main shafts that when combined to the small oil capacity and poor heat dissipation abilities of the trans in stock form will eventually fail. My sonic ended up losing 3rd gear and I suspect it was due to a failing bearing causing deflection. Look for low boost codes and cat efficiency codes when you buy them because low boost usually means a cracked turbofold. The cat efficiency code (if it has a cat) can mean that the pistons are cracked between the ring grooves and allowing the boost to pressurize the crank case and blow oil by the rings when you back out of it and the throttle closes. My sonic had this happen after rev limiter runs in the snow so I parked it. These cars say they can run on regular but I later found on the forums that they really need premium and this likely contributed to the failure when combined with running it hard. If you buy one needing a turbo replace all of the lines going to it as they can become restricted and actually cause a turbo failure. Another thing worth mentioning would be the valve cover/ intake pcv setup that is prone to failure which will cause the diaphragm to fail on the valve cover leading to running issues. Lastly, and the reason I got my current Cruze for $700, the bolt that holds the ground for the coil can come loose and cause random stalling/no start issues. I’m sure there’s more I’m forgetting but those are some of the core common issues along with what I stated previously.

Can confirm everything said here. Have a 12 cruze because it was an "upgrade" from a 10 corolla. This one had a coolant leak that we thought was the water pump but turned out to be the thermostat (it seriously looked like the coolant was coming from the pump). If only GM had used metal instead of plastic on the cooling system I think a lot of these issues wouldn't be as bad. However, there is no excuse for the location of the oil cooler. You can't tell it from this video but it's located behind the turbo and cat right on the block. Destined to be cooked alive and leak (which they all do).

To get to a decent GM 4, you either have to go back decades, find one where they "sawed off" part of another one (like the 4.3 was with the 350), or they absorbed it through acquisition like with Opel.

New front crank seal. MSD coil pack. Iridium plugs. And new belt with tensioner. And full maintenance service including transmission I noticed some oil consumption. Pcv failure in the intake. And the valve cover, which was replaced as well. Oil was everywhere. Intercooler, intake and charge air piping. Ordered a catch can and pcv fix from supercruzes (he has a YT channel as well) Used my borescope and found that the wastegate was cracked around the valve mating surface in the turbine side. Went to supercruzes again. Ordered a black widow stage 2 turbo with upgraded wastegate. Aftermarket intercooler and new charge air piping. Then i started having coolant leak issues. one at the thermostat housing side and one on the driver side of the cylinder head. both parts, PLASTIC. i took a gamble and ordered replacement parts on amazon that were aluminum. just an FYI, if you do this. invest in an o ring assortment kit from a local auto parts store. they dont include the right diameter thickness o rings in the kits. and also, red scotchbrite pads are your friend. they will help remove any machining burs and will tell you if your mating surfaces are flat ( flat bar stock and fine grit sandpaper will cure that issue) and lastly, do not use the coolant sensors that comes in the kits either. the ECM doesn't recognize them. either re use your old ones or buy new ones from local auto parts store. All of this was done before the next service date. I'm a die hard Mobil 1 oil consumer. And the inside of this engine is a night and day difference internally and mechanically, since all of this work has been done. may seem biased on. but the results speak for themselves. It purs so smooth at idle and accelerates so nicely over what it was when I bought it. 10k car and put roughly 4k in it. It's ultimately what you're willing to invest, to make a vehicle last. And keep up with your maintenance

[@jugo1944]

That sounds like a shitload of repairs for a 78k engine

[@spinsall87]

@jugo1944 yes and no. In the long game. If I continually do the regular service and maintenance throughout the rest of this cars life. It will be well worth it. Regular maintenance is a small cost to pay vs failure and fortunes to replace major parts. While not 100% guaranteed to eliminate component failure. You're leaps and bounds ahead of the curve and have a whole lot better advantage from facing failures. Mind you, aside from the turbo replacement and minor cosmetic trimming to fit the aftermarket intercooler. The rest of the work was very minimal labor intensive. Granted if you have the skill and/or the confidence to do it. 78k miles can easily last to 200k plus miles

The gen 1 Chevrolet Volt (2011-2015) also uses this 1.4L has a range extending generator. It’s tuned a little different, it never exceeds 4000 RPM and is designed to run in it’s sweet spot most of the time, which is 1400 to 2400 RPM with 80% to 100% throttle opening. The engine in my 2011 has been perfect, but I regularly change the oil and keep it very clean. In the Volt application, it is normally aspirated, uses a normal screw on oil filter mounted on the cast aluminum oil pan. And there’s lots of other differences. Because it redlines at 4000 (or 4800) RPM, it has very mild cams, and soft valve springs. My Volt has over 150,000 miles but the ICE (engine) has probably only 60,000 or 70,000 miles I’m not sure exactly. As long as you keep the oil clean and at the right level, it will run for a long, LONG time. I ALWAYS check the oil level when I add gasoline (which might be every 3-4 months) and sometimes I will just pull the dip stick for the hell of it. I have never NEVER had to add a drop of oil between oil change intervals. And I typically change the oil once a year which is about 3000-4000 miles of ICE operation. Most of my driving in the Volt is under battery EV so the engine is just dead weight going around town hanging out and not doing anything lol.

[@Imapersonv3]

I'm willing to bet that the volt application also doesn't have the oil cooler setup that the turbo model does. Which is where 90% of the oil/water mix happens when the o-rings fail inside and create milkshake, overheating, all that fun stuff.

[@paulstandaert5709]

@@FixingWithFriends I can tell you. Their PCV systems are absolute garbage. The cars tend to generate an "underboost" code which is fixed by a new turbocharger. I don't know what was wrong with the old one, but apparently, it demands a check engine light when they don't quite make the turboboost they are supposed to. The thermostat housings are garbage and fail regularly, the oil coolers behind the turbocharger leak all the time, and the latest Cruze I worked on had a failed water pump at something pretty decent like 216,xxx miles. Well, the pump was fine. The O-ring around it shrunk and started leaking. The last Buick Encore I was into was leaking coolant at the banjo fitting at the turbocharger. Heaven forbid they use a copper crush washer instead of a steel washer with a rubber insert which shrunk and started the leak. That was a big deal to get done. 40,xxx miles on that car, and it was a 2018. The "hard parts" of the engines seem good. No valvetrain issues, no bearing issues, and not an unusual amount of heads cracking or head gaskets failing.

And here I am watching this and owning a 2012 Sonic LTZ with a six speed manual and it just ticked over to 150,000 miles and its still a fun little car to drive. Thing is though, with the early first models of the Sonic like this, they don't have vitals gauges. At all. The only real 'gauge' is the tachometer, with a digital number speedometer reading because the theme of the car was to be as "motorcycle inspired" as possible, so all the other important gauges that you come to expect like alternator charge and engine temperature are literally reduced to idiot lights on the dashboard and at first I found this kind of neat, but now I've come to find this stylistic choice stupid because what exactly does the light mean? As far as know its 'off is good, on is bad' for telling conditions of things that shouldn't be judged like that. In later model years they actually programmed in digital readouts that you can scroll through on the dashboard to know some vitals of your car, but for my early Sonic, I got none of that to go by. Instead I've come to be extremely in tune with my car and just giving glances under the hood for anything amiss; its actually saved me in doing so. There was one time I was faintly smelling antifreeze when parking in my garage but with nothing obvious underneath I let it go, but then began hearing coolant gurgling through the heater core and knew something was a bit wrong. A T-shaped coolant return fitting had developed a hairline crack and was bleeding the system dry, but never was there any real indicators aside from smell and sound that there was a problem, and had I not fixed this my car would've left me stranded.

I think the biggest problem with these (and other similar engines) is that turbo and cheap should never be used to describe the same engine, especially when it is a higher performance engine. I know 138hp doesn’t sound like “higher performance” but you have to remember this is a 1.4L engine that is making 100hp per liter of displacement. That would be the same as a 500hp 5.0 V8. This is NOT a low stress engine, but it’s built to a significantly low budget and put in cheap cars that don’t get maintained well. Even Honda struggled with that same formula.

Currently have a coolant leak around the oil cooler ( no oil and coolant mixing thankfully ) but I am going to be replacing all the seals and o-rings with better quality ones. I think this car will last me a long time in large part due to the fact that I do check under the hood regularly and don't put off any strange sounds or weird behavior until it's too late. Unfortunately I can see people to whom regular and preventative maintenance are an afterthought having constant problems with it. It's a pretty good car that I enjoy driving and it's my first American car ever after only having Toyotas but the amount of issues in less than 70K miles shows how much the work the US car industry still has to do to catch up to Japanese cars in terms of long term reliabililty.

I remember working on those under factory warranty. The 2.2/2.4 ecotecs in other applications were way better in my opinion. Did lots of water pumps and thermostat housings under warranty on the cruze. The cooling systems were prone to air locking, so you needed to vacuum fill them. With that said, any small coolant leak allowed air in, which could lead to over heating. Combined with the worthless oil life monitor and lowsy oil filter setup, it became quite the disposable car.

That being said, i got that car from California since 85k miles, and maintained it meticulously. Finally died at 195,000 miles by back hit by a salt truck in Illinois. During that time, it had an issue with the thermostats getting stuck open every couple years, the PCV valve failed around 120 k mi, but the problem with it is that the valve is built into the valve cover, so you can't just replace the PCV valve, you have to go out and get a $200 part from the dealership or your idle will be surging all over the place. Intake manifold variable length valve, whatever its called, failed at 180k, $2000 with parts and labor. There is a coolant passage running thru the intake manifold, so you have to drop the fluids to replace the manifold, i think thats such an unnecessary design. Honestly probably because i maintained it really well, that car was amazing to me. Even with a stick, no, no, its not fast 😂 but dang i was gonna run that thing well past 300,000 even on the original clutch (i float the gears so i use the clutch a lot less) Oh yeah, replaced timing belt at 125k k and changed coolant every two years. Original radiator, alternator, clutch, valves, and all killed prematurely despite its many miles. God, i miss that car

[@damontroch4765]

So you think thats reliable 🤔 🤣😂 I had 244k miles on my 2014 Impala replaced plugs 2 times. Changed all the fliuids twice and replaced and Egr purge value at a whopping 24 dollars. Never did half of the crap that 1.8 needed

[@mikeanthonybrooks]

@@damontroch4765 congratulations. I may have done a lot more than the average person would have done, but I was going to make that car last a million miles if I could. Got totalled in a wreck unfortunately

[@drakepohl7410]

I work at a used car dealership that has a strong affiliation with my local GM dealers. The sheer amount of intake manifolds, camshaft covers and water pumps our shop has done on these is insane. 99% of them that even have big problems that we see don’t even have 80,000 miles either.

[@cheeseballs3825]

I love my little Cruze. Got 181K on it and it runs great. I've had it since 34K miles. I've taken alright care of it. I usually change my oil around 0%, I flushed my trans at 120K. I did have some of the problems you mentioned, but for as many miles as I've put on it maintenance has been minimal. My waste gate went bad around 80K, water pump around 160K, valve cover gasket somewhere in between those two. Other than that I've had really good luck with this vehicle. Just a few coolant leaks and regular maintenance.

[@Breze84]

As long as you maintain ut they are fine. Have a clean beater 2012 Chevy Cruze with 168000 miles. Runs flawlessly. #1 problem to address is the bad PCV setup. The check valve is in the intake and has a 100% fail rate. Once that check valve fails boost pressure gets into your crank case and pushes on the seals, #1 seal to blow is vavle cover and the freah air diaphragm causing a vac leak.if you plug the old check valve hole in the manifold and run a external check valve you will have 0 issues with the 1.4... mine drives smoother than my new explorer ST lol...

[@migueltron24]

I actually owned a 2013 chevrolet cruze, bought it with 30k miles, and always did the oil changes at 4.5k every single one and with good sparkplugs, and now my brother in law drives it to college back and forth and 150k miles now and only water pump has been replaced. Never mistreated the engine, and it is still good on gas and engine

[@acguy661]

In my 3 years working in a Chevy dealer, I think I resealed every part of these engines other than a rear main seal. That includes vacuum leaks, coolant leaks, and combustion leaks. The 1.8 was the better engine to have if you performed regular maintenance. As bad as this engine is, I'd still rather have it than the newer 1.4 that replaced it (replacing cracked pistons at 13,000 miles).

I didn't know that the first gen Miata had available rear steering. Since it can already to a u-turn on a two-lane road I guess not many people got that option. Great video, as always.

[@QuincyStick]

The rear steering that miatas have is from slight play in the suspension bushings, which cause it to toe in/out slightly through turns, also known as "passive" rear steering

I would say the worst GM 4 cylinder was the Chevrolet 2300 they put in the Vega in the 70’s. It was a die cast aluminum block without liners lol

[@jamesengland7461]

Before his time 😂 But also, it had flaws, but not the number of flaws he's already mentioned before even starting the teardown, so there's that ...

[@jamesengland7461]

And the aluminum cylinders without liners was actually a brilliant idea, poorly executed by GM, and later mastered by BMW and Mercedes. The cast iron head was unforgivably stupid, and so was the base model Vega having a half- size radiator. Most owners would've never experienced an overheat if their cars had the optional radiator.

[@sunbeam8866]

@@jamesengland7461 Not quite! A friend worked at a BMW dealer, and they had problems with their 'sleeveless' aluminum engines too!

[@gold98gtp]

I had a 72 Vega , ran great, no issues IF you checked the coolant level frequently, GM fixed the problem by adding a coolant overflow reservoir.

[@3800S1]

Sounds like they did a briggs & straton, worst power equipment engine ever. They always just blow up due to poor lubrication made worse because they consumed all their oil after an hour or two of use and that was due to the all alloy bore and the hone marks disappearing after the first use. They kinda fixed it with iron lined versions but they still broke often. In Aus, the worst GM engine which also happen to be a 4 cyl was the Camira engine, they failed often and gave Holden a bad wrap for many years which probably made one of their most successful models of all time the VN commodore not as well selling as it could have been, that had the Buick 3800 LN3 and L27 in it which in my opinion is the most bullet proof engine GM ever made with the the iron LS variants 2nd and then the 3800 II/III in 3rd.

[@Senior_Mustard]

Interesting small engine teardown, I'd be interested to know if you've ever taken down a Rover K-series 4 pot engine, these came as 1.4, 1.6 and 1.8 litre DOHC units and were fitted to the UK Rover 25, 45 and 75 cars from around 2000 to 2005 when Rover went bust. They were also used by Caterham and a couple of others. A common problem with these was HGF, often due to overheating issues and poor quality parts.

[@arnoldmiga5689]

I second this, I had rebuilt one of these and they indeed have different design in places like the super long head bolts going from head to the main bearing carrier. Perhaps not available in US though. I had a rover 400 1.4 and a rover 75 with 1.8, both K-series and I actually rated them high when they worked. 1.4 was very revving and suited well the 400 (honda civic body) and 1.8 was less revvy but more torquey which suited the 75 (both were way underpowered by todays standards)

[@Ay1Hunnayt]

Wife has a trax w a 1.4, chevy didnt add a single way to check any engine info on the dash not one. Only warning lights, maybe this engine had a car w the same thing?

[@codejunki567]

I can attest - I had a brand new 2014 cruze all the way until 110k miles until I smacked a chair on the highway. I loved my cruze so much and it never game me any issues :( ( I 100% took care of everything on time like my dad taught me too )

[@JohnStarbuck-hj9ls]

Love your stuff, I just got a 2013 cruise for 150.00 just to run around town and started to research the good bad ugly, this oil change must be done often on time, oil feed for turbo clogged up at bangi bolt, other major deal the ridiculous design for the PCV that fails and head, pressure builds blowing out gaskets and intake timing chain cover, oil pan thx for your channel, signed bymechanic, lol😊

[@94XJ]

I beat the living hell out of mine with a tune for years. Granted I bought it new and stayed on top of the maintenance because of the way I drove it. Fun little car that was a HUGE gas saver coming from my A6 before it. The stupid check valve for the PCV did fail but that was the only thing I ever had to fix, but I didn't have it for even 70k miles. I do miss that car, though. Cheap, ran like hell (thanks, ZZP 😁), economical and comfortably fit my 7'1" frame! Definitely has *all* the Opel fingerprints on that engine design, though!

[@hokie9910]

Anything will last 70k miles, good grief man. Please don’t comment on how well something ran when you only put 70k miles on it. This may confuse folks who are not that mechanically inclined into thinking it’s a good car..which most definitely these vehicles are not. It’s like folks who get on saying but my Jeep Cherokee is such a good car, stop hating, then you ask how many miles they had on it before they sold it and they are proud to announce it had nearly 80k miles…. Please help all of us to stop the insanity and help people buy only solid cars.

@@bradhaines3142which is why I left that as a qualifying statement...that I only had it for a few thousand miles. Yall upset because I put the disclaimer that I didn't have it for very long. My sister wound up keeping her Sonic for 6 years and clocked almost 120k on it without any issues. I know that's not that long or many miles to some people...but I guess our family just gets bored of cars fast or something 😊 I will say - 70k miles for a 1.4 running 20 pounds of boost (would sometimes spike to 22 on shifts) with just lightly modded intake manifold (the little tumblers in the runners were removed), better charge pipes and test pipe as well as hooking up an e85 sensor (provisions are already there for it...very easy mod) and some larger injectors, that little engine was pushed WAY harder than it was ever intended to be. For what it endured, I respect the engine and under different circumstances I would have gladly kept the car as a little econobox that rides nicer than my truck (also 40mpg to 14).
