We have a 2013 Kia Rio , its been a great car . 225,000 miles 1.6 engine , 6 speed automatic . No major problems . We bought it new . It is hard on brake pads , they are very small . Still have original pcv valve , took it out , still rattles , put it back in . Would buy the car again , without any hesitation !

Carbon buildup is common for all direct injection engines not just Kia's.

I want to add while we're on hyundai. I have a 2018 Elantra SE with a manual transmission. I have 123k on the 2.0 Nu motor. I cannot believe how trouble free this engine has been. Ok, its not peppy, at all, but i rock high 40s for mpg. At idle, its still quiet. I really am impressed. Now, im sure the way i tale care of it has a lot to do with it. The oil cap says "5w20". The manual says ypu can use "5w30" and if hot enough, 10w30. I have been using 5w30 synthetic oil and a good filter like Mobil 1 every 4k. I check and add any oil if necessary between oil changes. The 2 things that were done was a wheel bearing and a water outlet for the coolant. An inexpensive repair. If be surprised if i couldnt get 200k or more on this engine.

It sounds like a prime candidate for a small water injection system. Those actually steam clean the combustion chamber. The few I have disassembled after high mileage always look like brand new in the chamber.

I have a 2018 Elantra with the 1.6T. Currently has 106k miles. Haven’t had any issues. I use premium fuel, 5w-40 oil; 5000k mile intervals. Intake valves were walnut blasted at 90k miles.

This is very helpful information. I'm extremely interested in the 2024 Hyundai Sante Fe Hybrid and was surprised to see this little engine used in such a large SUV. It seems like they've certainly got most of the bugs worked out.

This was excellent. From what I can see/read/research, it seems the 1.6 Gamma MPi G4FG may be the most reliable Gamma engine variant. Due to it's reliable (but less efficient/powerful) MPi. What do you think?

Its nice to hear that the carbon build up isnt a huge deal. I would say that by now the bugs should be worked out. The engine has been around for a long time.

I’m looking for information regarding connecting route failures in the 1.6 L GDI - I have a 2015 Hyundai Accent- I’ve already asked for a an extended warranty, but was denied, but I believe that this is a far more common problem than Hyundai is letting on in Canada

Solid video! My 2019 Accent 1.6 Gamma GDI runs really well on 91 octane - Thankfully / surprisingly the ECU allows the car to take advantage of its high compression and direction injection. 👍 The engine is significantly more zippy on 91 and the fuel economy improves around 5 MPG on the highway. I ran several tanks of 94 octane and even a couple 98 octane tanks to test the limits of the stock ECU. Performance and gas mileage suffered with any octane higher than 91. Shortly after I had a P0420 code and had to replace the catalytic converter (covered under warranty). The super high octane fuel not only hurt performance but they also damaged the cat. Figured I'd share my experience. This motor was designed to run 91 octane exceptionally well and completely changes the character of the car in my opinion.

Do you know if these are common block/components? Theoretically if I have a 1.6Mpi I could take a T-GDI turbo and exhaust manifold I could bolt it up and plumb it up and tune it? What about the IVT transmissions? How much torque can the IVT handle? Thanks in advance

I’m looking at getting a Kia Proceed 2013, it’s the 1.6L GDI engine, is this model a reliability concern?

Kinda nervous about my 2020 veloster turbo, i wanna push maybe 230-250 hp with a tune but not sure how it will hold over time. I plan incrase flow and remove air restrictions, the turbo oil line was something iv not heard anyone talk about but I'll def upgrade that. Anything else that might be effect alot by the increase in hp and boost? I know new spark plugs is good idea before a tune.

Can you tell me about the 2024 KIA 1.6L Turbo Gamma 2 Smart Stream Engine? I've heard that the Turbo is a Borg & Warner K03 & is a Twin Scroll Turbo? And I heard that this engine is not only a GDI, but Port Injection as well?? Thanks for your help!

I have 2016 Tuscan 1.6T. #2 misfire. I’m getting ready to pull the engine to take the head off. Leak down seemed to blow right out the exhaust. Could that also be carbon on the exhaust valve ? I’m hoping it’s a straight forward engine pull 🙏🏼

Thoughts on the 2016 veloster turbo? Im looking into getting one, it has 100k miles and i hear the rods can be prone to failing

I am looking at a Hyundai Tucson 2017, I have seen lots of reports of engine issues on the 2016 but contradicting info on the 2017 model, any opinion on this engine, (1.6L)

I think the Kia Proceed GT has the 1.6 T-GDI (G4FJ) engige, is this engine model ok?

Added an oil catch can to mine to minimize the carbon build-up on the intake valves. GDI engines should come with these from the factory

No mention of oil consumption? That’s a huge issue with these.

I've got a 2017 veloster turbo r-spec, and since you seem knowledgeable about these motors, how hard can I beat on it?

Family wanted a Veloster with this engine. Car was leaking oil, leaking coolant, transmission would not go into 2nd (manual Veloster not auto), and head gasket was blown. Seller tried to scam us with a broken car.

Mine has a slight ruff idle whenbi cold start it every morning but goea away after 10 seconds and all is fine after. Should i be worried??

I’m confused. Does the 2022 accent se have dual injection? I’m getting different answers

So what your saying is, rather than a catch can. You vent it to atmosphere. Or somewhere that rusts for active rust protection😅

I don't blame hardworking folks who dare NOT touch any Kia or Hyundai vehicle. With the massive bill they shouldered from the engine failure fiasco plus other major safety recalls, guess who will foot the bill eventually?

Bro jus solved my emission code.. I thought it was the fuel neck.. I replaced it and code came back immediately.. didn’t kno it was a $40 piece that’s I could replace myself 😂😂

My 17. 1.6 t tucson is consuming a qt per 1000 mi. 55k on it ??

Have a 2017 turbo with DCT, have intake, exhaust, just put on an oil catch can a few months back and got the intake valves cleaned. Bought it at 87k and at 115k miles currently and still runs great even at WOT. The only issue that I ever had mechanically was a bad fuel pump. The car is not as bad everyone makes it out to be. Yea some come out bad and shit the bed immediately but what car brand hasn’t had bad model years/recalls? As long as you do proper maintenance and don’t dog it everywhere, this little clown car can go the distance with little issues.

I’m looking at buying a 2016 sonata sport, are there certain years that I need to avoid?

In a Kia Rio 2019 s … does it have a gamma or a gamma 2 ?

I crack up at Hyundai s 10 year warranty. Everyone who buys one thinks is really something. Then they find out it takes a class action lawsuit to get them to honor it.

I recently bought a Kia 2023 forte gt manual transmission..what would you suggest I get ? I only have 12000 miles on it ? I’m new the car world n terminology . Have a more tutorial for dummies on the 1.6turbo ?? lol 😂

Thats why its detrimental to use atleast mid grade gas, gas additives occasionaly between fill ups, only OEM oil filters and change oil every 3500 to 4k miles. These engines as all kia/hyundai engines have weak oil pumps.

Does Hyundai offer this walnut service at most of their dealerships? is it astronomically expensive?

Does the 2018 elantra sport 1.6T gdi have these issues?

Mine has 226k miles. 2014 kia rio.

I use 91 octane gas and a fuel system cleaner every 10000 miles , should have no problems for the life of the engine

I thought the 1.6 is not port injection

carbon will cause the valves to stick open

blowby will cause oil leaks

Save you a bunch of time; Don't mess with these things, they are trash. Just buy Toyota or Honda.

Just now the theta engines are blowing up. Now gamma. Don’t have high hopes.
