Interesting to see this...considered buying the wife a Spark, in part because we keep our cars for a long time and the simplicity of the Spark's engine (MPFI, no turbo, chain driven) makes it a good candidate longevity-wise. Ended up getting her something else, but I'm not seeing a lot here that would deter me from picking up a 5-speed Spark in the future. And I'll wager that the carbon build-up is because the car was only driven on short trips. One good long trip would have cleaned things up

[@inspectorjavert5563]

on paper it's good, but at the end of the day it's a Chevy. they are not reliable, and the dealers don't know how to fix them when they break.

[@SPAZTICCYTOPLASM]

The carbon build up is because the engine hasn't fully worn in yet, piston rings can take up to 5k to wear in, especially the modern low tension rings with friction coatings they don't contact the cylinder walls as aggressively as the old school stuff did. So oils getting past them and it's gonna burn a little oil. Engine break in is really really important. The wear on the cam and cap seems mostly normal maybe it's part of wear in, you'll open that engine up at 200k and it will have about the same wear up there. They don't have any issues with cam journal wear that i'm aware of. This engines simple because it was developed to be used globally especially in upcoming markets, they do have a lot of single use fasteners though. They're OK as far as modern economical tiny engines go.

[@speedkar99]

Yeah from a design perspective it seems very simple. That cam section worried me as I've opened much higher mileage engines with not as much wear. I can understand the break in period (usually upto first oil change), but can we believe all that carbon is going to just burn off?

[@TheStillWalkin]

I just want to say: as a new viewer and fresh engineer i really appreciate your quick to the point explanetions, analysis and way present every engine or part. Your perspective is invaluable, since in my academic time i disassembled maybe only 1 or two single piston engines

GM has one upped the German's use of proprietary fasteners with single-use security bolts - dealer repair strategy award right there - joking aside, given the valve cover surface chipped with prying on it, snap-off bolts that prevent overtorquing make sense

Good question. I hope someone knowledgeable answers.

[@BitterCynical]

Had the same thought. If the oil pump was most of the time working at fraction of what it can output perhaps the camshaft wasn't getting sufficient lubrication? And why make it variable in the first place? A tiny bit less fuel consumption due to less work being put into generating oil pressure?

I love that rigid bottom end and the hydraulic lifters. The plastic water pump impeller I don't love, but it's nothing I am not already familiar with coming from Dodge. As long as you never overheat it and replace it immediately when it fails, you can live with it. Security screws are stupid, but you can cut a straight line through them to pull them out with a straight slot. The engine isn't all that manky honestly. A simple MPFI open deck four banger sounds pretty good in my book. Pair it with a manual transmission and there is less to go wrong. The typical GM electronic gremlins are what make me most nervous. Don't let your grounds rust (thinnest and feeblest of all manufacturers) and pray for the integrity of your sensors.

A lot of new cars swipe the gauges when turned on. A lot of new cars also seem to fire up right up to a higher initial RPM than older cars. I got two that only go up to 1.25k RPM when fired up cold. New ones seem to sound higher. Wonder if the gauge sweep is to hide that.

0:10 i'm really interested in what kind of technology they use to make not only a 1.4 cylinder, but also make it be a 4 cylinder at the same time.

Weird that it has a steel oil pan and metal valve cover

[@NoorquackerInd]

Too much flow _can_ cause issues. There's a famously strong engine from before the 2000s (as most famously strong engines tend to be) that had only one flaw which was sending too much oil to the valvetrain at very high RPMs, causing the engine to starve itself of oil Edit: the engine was the Nissan RB26

[@Giuliana-w1f]

@@NoorquackerInd i think there's a few differences between a 1.4L shitbox GM engine that probably revs at most to 6500rpm, and an RB26DETT that revs stock to 8000rpm, on track, and maybe modified to rev higher. I'm sure there's a good middle point for the oil pump where it has enough flow for everything, and it doesn't empty the oil pan

[@speedkar99]

Less oil flow is less power robbed from the crankshaft.. more efficiency

[@TassieLorenzo]

The wiring inside the sump for the variable oil flow solenoid breaks in the Mercedes 4 cylinder engines. It's a quite an expensive job just to replace a $10 piece of wiring as it is at least a half day's work to drop the front subframe to remove the sump.

[@speedkar99]

Clips are going to wear down and fall off. Bolts don't do that

[@sethflorentz4809]

A thin oil has no correlation to wear in engines unless the engine is improperly designed.

[@TassieLorenzo]

It depends, thicker oils have higher high temp high shear, HTHS, values -- they retain better film strength at elevated temperatures but as you imply, this can be compensated for by using high quality base oils. It depends on how much heat there is in the engine in racing conditions. Obviously thinner oils have lower friction which is important for MPG and CO2/km in road cars, and important for more horsepower in racing. To some extent, when the engineers specify 0W16 or 0W8 for a Chevrolet Spark or Toyota Prius they might be assuming the engine will *never* be driven hard and the oil will never get very hot, due to the type of vehicle. Usually racing engines will only use 0W16 or 0W20 for qualifying and then use something like a 5W30 or even 5W40-10W40 for say a 1000km race. It depends on the engine design and the quality of the oil (i.e., is it a PAO or ester synthetic as most racing oils are). Porsche Carrera Cup cars and GT3R vehicles still call for relatively thick oils in circuit use IIRC. It seems Carrera Cup cars run Mobil 1 0W-40 like a road going Porsche GT3, however Mobil-sponsored motorsport teams elsewhere often use oils like the Mobil 1 4T Racing 15W50 from Mobil's motorcycle oil range (obviously not in a DI turbo engine, but rather a port injected Chevy smallblock V8).

[@speedkar99]

Well maybe this engine is improperly designed...they use the camshaft to feed the hydraulic lifters

200k engines if maintained. 300k is an impossibility from what I've encountered. They are built well, just not built for longevity. After 200k, they are to be thrown, or expected to be thrown away, cause that's usually when the timing components are destroyed, carbon has ate up the valves and cylinders, cams are worn from varnishing, and bearings are worn.

@@speedkar99 Very strange. I think they just left it there from the turbo version, and didn't bother to redisign it without it. My 1.4l 8v NA 75 hp engine does not have it. A 0.9l 45hp engine I drove did not need it either...

[@silveraxe1988]

Do you think poor gas would build that much carbon in the combustion chamber with only 2000 miles on it? I’m thinking loose rings maybe?…..I doubt it’s would be that rings haven’t seated into the bores especially with 2000 miles in it they should be well seated by this point I would think.

[@speedkar99]

Maybe it's the PCV system

[@victorwilks88]

Opel power 😮

[@larryschmidt977]

the cam caps or whatever you called them have no bearing I could see and those grooves are from filth in the oil

[@CanielDonrad]

Oooo what's inside an ecotec engine? Probably not all the rods. At least one punched the block.

[@speedkar99]

Not this one yet. I have another video on Ecotec engine that failed big time.

[@CanielDonrad]

At such low miles I wouldn't expect it. But I imagine around 100k those bearings realllly start to wreak havoc.

Gratuitous comment intended to inflate the number of responses to your video.

Well thanks ☺️

At least everything is made of metal instead of plastic ( bmw, Chrysler, Honda, etc).

[@speedkar99]

True

[@finalbladecrisis]

Had a 2012 equinox with one of these ecotech engines in it....and now i will never buy a chevy again. Failed with no warning. Oil was maintained, since i knew about the oil burning from the outset.

Im no defender of Garbage Motors but in this engines' defense it was probably driven by a teenage girl that always floored it a nanosecond after it started, add to that its winter, and winter in Canada. Can perhaps explain cyl wall wear from cold-engine slap, extra carbon, and other wear points inconsistent w/such low kms. Also very well may be why car was wrecked to begin with. She was busy texting and painting her nails.

[@craigiefconcert6493]

It’s actually a pretty fancy little engine: Ladder frame, aluminum, oil squirters, VVT. Too bad it’s GM and will likely fail quickly, but at least better than Kia or Hyundai. Too bad you scrapped it-would have made a nice go kart engine 😉😂😂😂

[@NotAnonymousNo80014]

You know downsizing is out of control when they start making 1.4 cylinder engines.

[@speedkar99]

1.4 is nothing. See the RHD market where this is considered oversized and they'll tax you on it.

[@NotAnonymousNo80014]

@@speedkar99 I know, my car has a 1.0 engine, but at least it's a 3 cylinder LOL.

Downsizing is very practical. You can increase your skills, speed, or proficiency to raise your hourly wage. You can increase your worktime to increase your yearly income at the expense of your hobbies or family time. But, my favorite method is to just not spend money. Not spending $20,000 extra will have the same effect as earning $20,000 extra. And it is literally effortless. Far from being out of control, I would argue that downsizing is a foreign concept to most people I know who spend their entire lives with the same low end skills making the same low end money, working 10 out of 15 wakeful hours 5 out of 7 days a week, buying a lot of useless crap, never earning interest or dividends or saving for retirement, getting into debt to acquire more useless crap, thus staying on the losing side of compound interest and watching their children grow up in fast-forward. A cheap, reliable car is a godsend for taking control of your finances and your future quality of life. You could do that... but y'know V8 go Vroom vroom.
