Part 2 of 2 - Assembly - Replacing piston rings on a 1.4 Turbo (Chevy Cruze, Sonic, Encore)

- Another Chevrolet Cruze in the shop today for the same deal - bad head gasket. After replacing the gasket, I found that it was low on compression. In last week's video, I showed you how I tested compression and discovered it was low, and how to disassemble the engine. Today, we're putting it back together.

Here's what I believe happened - this engine was allowed to run extremely hot - overheated, in fact, for an extended amount of time. Probably until it finally stalled out or the driver reached their destination. This allowed for glazing of the cylinder walls, leaving them shiny, as you see them in the video. Glazed cylinder walls causes low compression and increased oil consumption (although I did not notice any blue smoke from the tail pipe).
Once I completed this project, my compression came back up to within spec, and the engine is finally running perfectly again!
The Cruze that I'm working on today is a 2013 (I think I call it a 2012 in the video), but the procedure is identical for the 2010, 2011, 2012, and 2013. I believe the engine changed slightly for 2014 and newer. It is also the same engine that is used in the Chevy Spark and Buick Encore.

Thank you so much from Israel!! , I just finished fixing my Opel Zafira with the same engine I changed 3 broken pistons. it was my first time opening an engine. With your videos I managed to do it by myself and to save about $2500. 🙏🙏
You are very welcome! I am glad the videos helped! Thank you for watching.
Doing the same to mine currently. Broken ring land cyl 3.
Thanks for video. Very helpful!
Glad you found it helpful! Sorry to hear about your broken ring! Man, these engines sure to have their fair share of problems. Thanks for watching!
Hi, I have a 2015 Sonic with the 1.4 turbo engine. I did a compression test and these are my results. Cylinder 1 and 4 200 PSI, 2 and 3 are 80 PSI and 175 PSI. With wet test 2 and 3 come up 20 PSI can I assume piston rings ?
It's likely.... or your head gasket could be leaking between the cylinders. Having done so many of these engines, I would do all of it in one shot. Pull the head and send it out to be tested and decked, and while it's gone, throw a new set of rings in it. The rings aren't that costly and would give you something to do while the head is away! Hope you get it back up and running soon. Thanks for watching!
How are you able to rotate the crank 180 degrees if we are supposed to have those timing lock pins in place to remove the head?
Good question! You can remove the crank pin with the head off. You'll be setting the timing later on once the head is back on, so it isn't crucial right now to have the crank at TDC. Just be sure to put the pin back in when you're ready to put the head back on so you can set your timing. Hope that helps! Thanks for watching!
might be a long shot as this video is a little old now, but worth a shot. 1.4l ecotec got a really bad misfire and refuses to drive properly, cylinders 1 through 3 only held low 90s when i did a compression check and cylinder 4 only held 62 psi. Dont see any signs of a bad head gasket but i did fight with overheating problems for a while. planning to pull the head and my best guess is the rings but do you have any advice for a novice without a lift ?
Ooof. That is low compression for sure. The "good" news is that you'll be pulling the head to get to the rings and cylinders anyway, so you'll be able to rule out a bad head gasket in the future! Learn from my mistake though - while the head is off, send it out for testing and have it decked. Nothing worse than having to do the job twice.
The lift makes things easier, but is certainly not needed. You'll have the nose of the car up on jack stands, so your jack will be free to hold the engine while you remove the engine mount, so you should be in good shape. Be sure to hone those cylinders. As I showed in mine, they had glazed over from the engine overheating.
Hope that helps! Best of luck to you on your project.
Do you have the part numbers for the Torque Bolts you replaced underneath?
I don't. I got them from my local chevy dealer. They had them in stock, so I figured it was a pretty common failure!
so was the compression good afterward? How was the test drive?
Compression was great afterwards. Nice and even across all the cylinders. Sorry, I should have shown that. Test drive was perfect, and the engine is still going strong!
Hey! Great videos, thanks for posting. I've got a 2012 Cruze 1.4t 6 speed with ~170k and got these numbers for compression: 190, 155, 190, 190. Low cylinder shot up to >200 after putting some oil in it. Is the low cylinder enough to justify doing rings on it? Or should I just send it and keep driving...seems to run and drive fine otherwise. Thanks in advance!
Personally, I'd probably keep running it until it either starts missing, throws a check engine light for it, or starts blowing blue smoke / uses a lot of oil. It's good to hear that these engines are capable of that many miles! I see so many at the local salvage yard, most of which probably just have bad head gaskets... Thanks for watching!
@@3DayWeekendmy cruze has too much back compressor and I can see when I remove oil cap. Car has 292k km and driving really good as I have done many maintenance till now with genuine parts.
It is worth to change piston rings or should I replace the engine.
Can I do myself?
I have recently change myself all suspension with everything, all around genuine brakes, valve cover, waterpump and many more
Hi, nice video’s, i need a new piston STD for buick encore 2015 1.4L Turbo, so where can I get?
Thanks! I went down to my local Chevy dealer for all my parts on this build. Surprisingly, they had them in stock.
RockAuto.com has some available as well if you'd rather order some.
So the car over heated and I'm curious what should i all change the car has 170k miles on it. Of course idk what all did to it
Hopefully you were able to shut it down before catastrophic damage. I'd start off with finding and fixing the leak (these engines are known to develop leaks in several spots), then top it off with coolant and run it. Check for exhaust smoke that smells sweet, and check the coolant level every morning until you're confident that it isn't using any coolant. If that all works, you're good! Of course, if it's burning coolant, you might have a bad head gasket or warped head. Hoping the best for you!
If the 1.8 engine never shows the oil level on the oil Stick what it can be the problem???
Well, first thought is that you're low on oil, and that's a very bad thing. The only other thing I can think of is that you have the wrong dipstick for some reason. I would not drive it until I figured that out though. Low oil can cause severe engine damage very quickly!
I was watching a head gasket repair to an inframe rebuild, What happened?
Two separate video series, two separate Cruzes. I'm about tired of Cruzes!

@@3DayWeekendfully convinced Chevy misspelled Curse. Because that's what a Cruze is. A curse. They did a very cheap and poor job with these cars. They could have been so much better but ah well. Just wish I had done research before buying from the used car lot. 😅😅
Genius
Thank you!
When it first came in did it have a slight miss at idle ??
Not that I noticed. It seemed to drive fine, but it did have a code for a knock sensor. To be fair though, I didn't really drive it that much before I brought it in and started diagnostics.
Let me guess, rough idle with traction control and all other assists going crazy? PCV system. I would bet PCV system failure all day. Get a new cam cover, new cam cover gasket, PCV hose to the turbo, and a version 3 cruze kit with the PCV intake manifold delete (google cruzekits). That will solve this problem and keep it from returning. If all you do is get another cam cover, it will return in less than a year. You have to fix the manifold because monkeys within the Opel unit at GM had terrible engineering management and designed a complete failure of a PCV system for this ecotec engine.
If you were trying to make a proper 45 degree cross hatch, you need a whole lot less RPM and a lot more up and down travel. That HF hone made me cringe...I think a proper flexible ball hone (dingleberry style as some refer to it) would have been a far better choice. I have 4 Cruzes in the family so I'm curious to see how this turns out after some drive time.
I am in agreement with you, if the cylinder had damage that needed to be worked out. (Also, my dingleberry that size is MIA - loaned it to a friend, friend can't find it... you know how it goes). But, the good news for these cylinders is that I really didn't have to run it much. I think running the hone for such a short amount of time just took off the glazing, which revealed the original cross hatch in the cylinder. The cameras never show cross hatching really well, but it looked really good. 1000 miles on the engine so far, just did the break-in oil change, and so far so good! In all honesty, to properly hone a cylinder with any sort of damage, the oil injector would have had to be removed and it would have taken a lot more hone work. I think I just lucked out with this one. Thanks for the advice and for watching!
Machine shops don’t use the dingle berry style homes there is reason for that. , but just less rpm and deeper stokes is a plus for proper finishing.
@@mptorecon apparently you haven’t been inside many machine shops recently. Ball hones are used all the time for plateau honing as the final step.
@@madmat990not sure what kind of shade tree mechanic “machine shop” you’re going to but as many as I have been to not one uses a dingle berry style hone. Professional engine machines use precision stone head that they can vary tension and control head attack angle. “Dingle ball hone”, give me a break.
@@mptorecon OK "Mr. Top Fuel Engine Builder" LOL. Please tell us what engines you have built personally and we'll be the judge of how much you really know.
How long did the engine last?
The engine in this video had a little over 90,000 miles on it. The 1.4's are known for bad head gaskets. This driver continued to run it with an overheated engine which is what glazed the cylinders and prompted the new rings.
@@3DayWeekend no I meant how long did it last after your repair
@@wendellgreenidge3362 I'm not sure. It wasn't my car. However, they haven't called me and it has been well over 6 months so I would say it's still running strong!
@@3DayWeekend awesome!!!!! I would have to agree with you
👍👍👍
Thanks for watching!
Update?
Engine is running great. No issues as of yet!
Thanks for the update I’m looking at changing pistons in a 1.8 ecotec cyl 2 had broke a piston no damage to cyl walls
@@mikeyrozell5627 I’ve got a 2016 Sonic 1.8L that’s smoking bad. Looking at replacing the rings in piston 2
💙🖤💙💙💙🖤🖤🖤
Thanks for watching! Glad it has helped!
Hi
Welcome!
These motors are thrash
They definitely seem to have a high failure rate. Easy to work on, but it really shouldn't need new rings with under 100K miles, that's for sure!
