Here's why Scotty Kilmer was wrong about 1.4 Chevy Sonic/ Cruze timing chain and underboost codes! 

Thank you

I know I’m prolly 5 months late, but did you try cleaning out the cat? If so, what’d you do/use? Was it successful? I had a “clogged” cat on a Sonic with the 1.8 engine. Cleaned it out with a can of Seafoam in the fuel tank and I also sprayed a whole can into the throttle body. Cleared it right up and has been good since. No CEL, no codes. Also runs a lot smoother since doing that.

Thank you!

Welcome

Put some engine oil in it and the noise should be quieter.. even a brand new one will make the same noise after some time although there's nothing wrong with it .

Thanks. Crazy thing is I'm not even a mechanic lol. I just like to save money and help other people save money as well.

Engine mounts?? Why would you need to replace those? They should last a long time with a small engine like this

That’s why I say these are junk owned one never again lol

Thanks so much!

😆

Thanks

You're lucky you got that year because 2014 and 2015 are the most reliable first gens!

The valve cover is GM's fault they should pay for it, any smog device pcv is supposed to last 100,000 miles if not the manufacture must fix

@@thomasmorris302 it was covered under warranty, not sure if it happens again if they will cover it

@@thomasmorris302 I love my sonic and all, but the valve cover and pcv system is hands down this engines achilles heel. both in reliability and performance. I have pushed then engine at 22psi for most of it's life, and blown 3 valve covers so far. the pcv system boost aside is prone to failure, but the worst thing about it is that if it fails under a load it will belch oil into the turbo, which can cause a lot of problems but also scared the living shit out of me several times over.

I've owned my 2011 1.8 cruze since new. Them boys always bragged how much better the 1.4 was. The 1.4 is dangerously underpowered to where I felt unsafe on the highway. Still have my 1.8 mt at 360,000km, just traded my 2015 1.4 sonic with 74,000km for a 2014 toyota venza. Gm should be put under for the garbage they are producing. Iam 39 Years old and have owed 2 pontiac sunbirds, oldsmobile alero, cadillac deville, cruze, sonic, 86 fiero gt which I still have. Iam done with gm. The cars are pure garbage now, plastic engines from China. Toyota all the way from here on out. My advice to anyone with a cruze or sonic either engine. If you don't like working on your cars, sell it asap.

They make noise when they are bad and engine temp is warmed up and I don't think I even had a check engine light when mine was bad. I think it was bad around 80k miles.

@@koreymayo8884 When it becomes dry and dirty on the inside the noise gets louder..that doesn't mean it's bad so putting a lubricant inside helps clean and lubricate things and make it quieter..when it stops working and doing its job that's when the ECU triggers the check engine light.. usually causes small leak codes like P0456. Also sometimes the engine will shudder as if there is a misfire happening especially when the gas cap is opened and this is when the valve is stuck open and unmetered air is allowed into the system..so either way from my experience, Spraying a cleaner inside and then a lubricant will fix it for you and you don't have to replace it.

Curious as to why you replaced the camshaft position sensors and not just the seals? The seals are cheap and easy to replace. They are what leak oil in that area. I actually have a video on the procedure.

I didn't know I could just replace the seals when I ordered the parts. Garage estimated $760 to replace both. I figured paying $100 for both sensors with seals was a bargain compared to $760 and I wouldn't have deal with them for a while.

@TheFunKing33 Dang that sucks man. Were they easy to change at least?

Yeah except certain Honda models have bad automatic transmissions and a few 4 cylinder toyota engines had piston oil return holes that were too small and caused massive oil burning for a few years, but Toyota, Honda, Mazda, and Subaru are the most reliable these past 10 years. And some Kia/Hyundai/and Genesis are good too depending on the model. A lot of Kia/Hyundai engine problems are actually from owners going way too long between oil changes. It has to do with the type of person that buys those vehicles. They buy a car that cost less than all other car brands and then don't spend money on proper maintenance on top of the fact that kia/Hyundai manuals already tell you to go 7500 miles for regular and 10000 miles for synthetic and then some people go twice as long as that further compounding the problem. Even with modern oils I still go by 3 to 4000 for regular and 5 to 6000 for high quality synthetic like mobil 1 because oil is cheap, engines are not and you can never change it too much.

Sorry I've never had that issue with the coolant temp sensor, so I wouldn't know on that one.

Yep I agree.

They are trash! I own three Chevy Cruze. Okay, all trash. The first when I got on 2012 had 10,000 miles on. It was nice at first.

@@yodead369 My comment is about Sonics, not Cruzes.

@@SolveForX the same goddamn thing! lol. Literally the same motor, literally the same transmission, and literally made by the same piece of shit company. General Motors.

​@@yodead369 ouch lol

If the purge valve is making noise then it is bad.

A timing chain job is always expensive, but this car shouldn't need it, but there are tons of other things that always break and have to be replaced on cruze/sonic. I don't think a single year has gone by without me having to replace something on the cruze and only drive 6,000 to 8,000 miles a year! I would recommend a toyota corolla, honda civic, or Mazda 3 instead.

@@koreymayo8884 I like the looks of Honda CR-V's and CR-Z's what's your thoughts on either of those

@Robert Perry on the CR-Z don't get a first year 2011, but all the other years are good. On the CR-V they are up and down over the years, so research on consumer reports and carcomplaints.com

@@koreymayo8884 thank you very much for the info

Idk stay away from these spend the extra money and get a Honda or toyota I just got a Chevy Cruze 2013 been to the mechanic 3 times and I can just tell stuff eventually gonna go just cos of how it was made

That's a code for multiple cylinders misfiring. Need to have coil pack and spark plugs checked. I would start there.

Timing can fluctuate for more reasons than just needing a timing chain replaced. A good technician would do a more thorough investigation. There's a lot of mechanics out there that don't know what they are doing and also a lot of mechanics that waste people's money for unnecessary work. If you trust all of scottys videos, then you are gullible. Some of his videos are on point, and some are way off. He is hit and miss.

Yes. This video is incorrect. Scotty was right.

Geez man that's terrible and I've had too many problems with GM cars and seen way too many problems with Fords from my other family members, so I'm most likely sticking with Japanese cars from now on and maybe Korean Kia/Hyundai.

@@koreymayo8884 Yeah. I gotta little toyota yaris right now. 165k miles and running strong.

Yep some of the sensors such as the mass air flow sensor are bosch even when you buy "GM genuine" parts from rock auto.

2012 is the first year and absolute worst year for the sonic. I would avoid it at all cost. If you are dead set on a sonic then get a 2015 or newer to avoid problems. You can see all the problems on different sonic years yourself here... www.carcomplaints.com/Chevrolet/Sonic/

As you can see on car complaints the first 3 years 2012-2014 had the most problems just like 2011-2013 chevy cruze before they put a better wastegate acuator on the turbo, better cooling on the turbo, and better pistons in the engine.

Check the evap purge solenoid anyway. Put your hand on it and you can feel the solenoid clicking...see if that matches up with your sound.

True lol. He is very entertaining to watch, but it kills me that he costs that customer a lot of money after saying 3 other mechanics misdiagnosed it and calls himself an expert and then misdiagnoses it himself.

Right on. Yeah Scotty is fun to watch and the way he talks with his hands is entertainment too.

I'm in northeast alabama, but I'm not a mechanic though. I just work on my own vehicles and my family's.

A loud clicky noise when the engine is warm most of the time is just a bad purge valve soleniod for $20.

@@koreymayo8884 the more I learn about cars the more I realize there's a little of simple little 10-30$ parts that could use some replacing and attention from time to time.

@@koreymayo8884 I actually have some sort of 'bad efficiency' or 'low efficiency' code being thrown rn in my car. I can't remember exactly what the guy said that plugged it up for me, but do you have any idea what that may relate to? I'll being getting it plugged in again any day now so I can tell you the exact code. I hope this is the type of subscriber engagement you were going for lol! I'll give you all the likes and views I can in return for all your help. Hope it means something :)

@Pat Caron I replaced mine but seem to be dealing with a different tick as it didn't change at all. My dad who works on lots of vehicles says it sounds like fuel injectors. Others at the local shop suggested lifters. I'd just like to get rid of it lol

@@RandoManFPV A little bit of ticking is normal. It is normal for injectors to make a little sound.

Very true and If you have more than 70 or 80k miles and it's noisy and never been replaced then I recommend replacing it. They are cheap and only take a couple minutes.

@@koreymayo8884 yeah Im not against it just in no rush after replacing cracked head wasted timing guides and chain. Water pump thermostat, dropped oil pan and flush out sludge from the neglect.. it was never oil service properly, when a heater hose failed last owner drove it until it was bone dry and hot to the point of not able to run.. the rings cylinder walls crank all faired well. I revive this 1.4. I know it's not leaking oil coolant. No noise temp is good oil pressure is good is clean inside and out no leaks. EVAP rattle turbo leaks some oil into intake.. those can wait, why counts is been revived it runs great. It was a free car to my ole lady. I done enough for now... Lol.. I'll swap it and that turbo sooner or later. Just impress with results of the engine after what it was before.. these engines are designed well. People call them shit have no clue on engineering and structurally sound design of these.... I decided these are good on how it's built and how mine spared it's crank and pistons after the hellish abuse.. impressed..

@@johnfloyd2551 how did you get a cracked head? Overheated? For the price of replacing a cracked head and timing chain job probably better off with a whole new engine and even more worth a new engine if you still have original turbo unless you did all that work yourself to save money.

Exactly why I hardly watch his videos anymore.

I was advised by a mechanic that once I get to where I am going, to sit and idle for 30-60 seconds to let everything cool off a bit before shutting the car down. Especially if it was a long stretch of highway driving right before. Is this bad to do? I don't sit and idle for 5 minutes or let it idle on a cold start except until the RPMs die down, but merely 30-60 seconds once I get to my destination just to give everything a second to cool off.. is that wrong of me to do? I have a 2012 1.4 turbo

Coolant runs through the turbo it's fine

JUST MAYBE ...THE CHAIN WOULDN'T BE LOOSE, I'VE LEARNED, IF THE PLASTIC CHAIN GUIDE WAS TIGHTEN - HE DIDN'T CHECK IT

They are just like all Ford, Chevy, Dodge these days.

He sounds more drunk if you reduce the playback speed😂😂

@@jessesan2003 LOL c'mon that's not nice

@@scsi_joe 🤣

You are hearing the fuel injectors...sounds like a sewing machine. 100% normal. If you are expecting no click noises, you are going to be disappointed.

​@@P1ayCrackThe5kyBeat me to it. People don't know that sound is normal these days or what pressure injectors are operating at these days. It sucks to worry over nothing.

He is always blowing his own horn. He has a big Ego! I didn't think of it until you mentioned it, but I've never seen him do a big complex job, such as engine repair.

My accent is half from Alabama and half from Miami, Florida. I'm American.

Sounds like a diesel.

That's amazing milage especially for a first year cruze. Is it a 1.4 or a 1.8 and automatic or manual?

@Korey Mayo 1.4 automatic.. It's been a great car

@str8 menace I'm surprised the automatic transmission lasted that long! Chevy cruze and great car don't usually go together in the same sentence from most owners lol. How often do you change the transmission fluid?

@Korey Mayo and don't be thinking I baby this thing either.. typical man child acting like Tokyo drift... I've done a pcv delete , ported intake, and changed oil around 3.5k, Trans fluid 75k or when I decide. I've owned chevys my whole life and I think they like to be beat as long as you take care of them. My 09 silverado has 309k all original

@@str8menace923 how did you do a pcv delete?? My 2011 1.4 turbo has terrible idle, hesitation, and a terrible noise from the engine and I’d like to get rid of any problematic parts that I can lol
