What's Inside a Brand New GM Ecotec Engine

Here's a look inside the GM Ecotec 1.4L LV7 SGE engine and how it works!
This engine was out of a 2020 Chevrolet Spark with barely 2,000km on it and is practically brand new. It features dual overhead cams with variable valve timing, port injection, aluminum heads, block, upper oil pan and even a metal valve cover!
The engine's overall design is simplistic yet economic, with a simple timing chain running from crank to cams, a variable oil pump, and an exhaust driven vacuum pump. Amenities like variable induction intake manifold are omitted, as the design intent here was to maximize fuel economy at a very low cost.
Overall while the engine's design is simple, the lubrication system is quite complex, with oil flowing through the camshafts and then back around to the hydraulic lifters on the intake side. There's a lack of gaskets used when sealing, as cheaper RTV is established, making it difficult to remove and reseal. Most importantly, the combustion chambers consisted of a lot of carbon buildup for only having 2000 km on it, which was not expected, in addition to the cam caps and camshaft showing excessive wear. This could be due to the thinner oil used from the factory, a lack of break-in time and the combustion cycle being used.

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

[@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

[@speedkar99]

I'm glad you like it!

[@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?

That PCV valve hardware is interesting. So let's say the valve were clogged, are you expected to replace the valve cover or try to clean the check valve is much as possible and reinstall?

[@notmirelnam248]

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.

Is the variable oil pump only for variable valve time or in combination for fuel consumption also at high way driving ,and could it cause the issue on mains of cams getting worn that you found

[@FrankyRedEyes]

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?

[@oldguysrule-iv7sh]

@@BitterCynical I've been told the variable oil pumps will pump to 105 psi for the vvt but you wont see it in the gauge,then when it switches to 4 cylinder at highway driving it will go to 15 psi this on a 5.3 gm to prevent the drag on the crank, so I've been told, but I would rather have the old school system

I bet the heavy carbon buildup is due to excessive cold idle time. Low mileage for the age might be because it wasn't sold quickly, so it spent a long time at the dealer. Figure weekly starts (to keep it starting), every one cold (cam wear), no drive-time (to clean the carbon), and no mileage added.

[@speedkar99]

Yeah when it's cold it runs too rich to warm up the cats. The PCV system and oil type might have some factor as well.

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

[@dantevito1193]

@@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.

Isn't the Cruze a 1.4l turbo? I'm pretty sure they're known for turbo failure leading to oil ingestion, and causing the carbon problem you're seeing here.

[@speedkar99]

Yeah. Except this isn't a Cruze and doesn't have a turbo.

[@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

[@nickd.7267]

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.

[@DashCamSerbia]

Why does it need a vacuum pump?

[@mostlyuselessgarage]

He mentions it's for the brake booster.

[@TassieLorenzo]

Modern engines often don't make much vacuum, especially if they are turbocharged.

[@DashCamSerbia]

I am not asking what it is for, I know what it is for. I am asking why does it need it? It is not turbocharged.

[@speedkar99]

It's an economical small engine. Probably doesn't make enough vacuum at idle

[@DashCamSerbia]

@@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...

[@auntbarbara5576]

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.

You think that alone can cause buildup in 2000km?

[@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

Engine not run in, causing oil burning. Pretty poor on the line boring of the camshaft tunnels, though. I guess the micrometer man was on leave......

Engine break in?

[@einfelder8262]

@@speedkar99 Break in is the same as run in, I don't think this engine was ever warmed up, put under load, or given a good rev. Unlike some manufacturers, I don't think GM thrashes every engine at the end of the production line to bed the rings. Even then, many burn oil for quite a while.

This may sound extremely evil, but can't they use clips instead of so many bolts, similar to plastic housings? Metal should also be somewhat flexible. Parts could just click together, never to be disassembled again.

[@KaufDirGeld]

no.

[@jaccurtis5789]

Probably very difficult if not impossible to get enough clamping force holding parts together just with clips to stop oil/coolant leaking out (plus the added problem of making the engine even more of a throw-away item than it would already be), among other reasons I’m sure. Quite efficiently summarised by the reply above me haha.

[@speedkar99]

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

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.
