Most Hyundai engines blow up before they ever need their valves cleaned.

Maybe the kid in Canada who blew his 18 month old engine up by tracking the car at high revs should claim he was "cleaning out the carbon." 🤣

Just wondering when doing an intake valve cleaning on a 2022 Tucson limited hybrid in order to get the engine to kick in do you just press the accelerator until it kicks in the ICE and hold it? Any product suggestions for a cleaning product : so far I only see CRC as being available. I’ve heard of a lot of talk about an STP product that clips on the hood but when actually trying to find this product it seems unavailable now days? I only saw one online diy video but it was for a standard ICE engine Santa Fe with that afore mentioned product that I can’t currently find. Any ideas other than taking my car to the dealer?

You don't need any of that stuff. The following videos will show why

I’ve heard ots not good to clean the valves but a oil catch can should prevent the valves from getting carbon

The 1.6L engine has a built in catch can system incorporated in the valve cover itself. It is a different system than the older replaceable in-line device normally used. It is not even called a PCV on this engine. On the hybrid you can see it on top of the cover. It looks kinda like a tank turret and has a 5/8" or so line going down to the turbo. A catch can I think would be a waste of money

I fretted and fretted for a year whether to pay Firestone to clean the valves, then the engine blew out six weeks ago and Hyundai replaced it. Best $150 I never spent.

Oh my! that’s too stinking funny!

I finally got some pictures taken. Is the red circle the pcv intake? The other picture shows the location of the throttle body. I can barely even get a picture of it much less get my hands in there to take the thing loose to spray in the intake cleaner. That’s why I’m trying to figure out a different way to do this that’s easier.

Can a member confirm if the The Smartstream 1.6T valve cover (with incorporated oil separator) installed in the 1.6T Smartstream engine can be installed on the 2016-2018 Hyundai Tucson 1.6L Turbo G4FJ Gamma II T-GDI 4-Cylinder Engine, or totally different configurations?

You're referring to the Theta 4 cylinders from years ago.

Most "carbon" problems can be treated with a good couple of hours drive at highway speeds (70-80 mph). That gets the combustion flow at peak temps and dries out the inside of the engine. Add a gas treatment as well to maximize the action. Take a road trip and enjoy yourself instead of spending a few hundred at a dealership.

I have never seen an engine with carbon problems unless it is only driven at city speeds or is a commuter where the speed and temps never reach proper operating parameters.

We used to laugh that older people would only drive in the city and take in their Cadillacs for a tune-up. The tecs would just get in them and make a 20-30 mile drive at 100 mph blowing out clouds of carbon and soot. No mechanical work but the flat rate would remain the same. The cars would drive like new. Driving all the time at city speeds kills cars.

Gas treatment with P.E.A.. Presently that's Gumout Regane every 3k miles.

There is no PCV valve on these newer 1.6L engines. They have what is called a "pressure regulator valve". It is right under the hose you have outlined in the pic. It kinda looks like the top of a tank. On the backside of the valve cover right on the other side of that regulator valve is the hose that leads to the Turbo(if installed. Thats where a catch can would go if one wanted to waste their time.
