Prevent Carbon Deposits in Your Direct Injection Engine!

Just don't buy a GDI car?! WTF! And don't buy a VW? Just saying! Haha

Great video. I am picking up a 2011 GTI next week. I am looking forward to modding and autocrossing it. Where in Mass are you? I'm in Western mass.

What mileage did you start using sea foam? Currently at 92k on my mk6

They knew it when they implemented it. It wasn't some accidental discovery. The truth is they knew it would happen and knew how to combat it on the vehicles that were going to be under their care. Years later second hand buyers have found out. That's all.

Do a before and after

So spraying a cheap oil mixture in your intake is supposed to get rid of the oil build and breakdown of previous cheap oil. Sounds logical to me. Many of these products contain large amounts of oil, thus all burning oil and smoke which is leading to CAT damage. Doung these treatments dumps huge amount of hard abrasive soot in the oil, in the cylinder, and remainder of the engine. Oil analysis proves this. Use a 100% engineered synthetic oil will perfirm better, reduce oil oxidation and protect better. Castrol and just about every other full synthetic is just fini oil with an added hydrogen molecule so they can call it synthetic when it isnt. Follow the science, not oil company tricks and deception.

Hey from Rhode Island! More companies need to use dual injection like ford and Toyota does in some of their engines. Best of high worlds.

Just get a Tesla

If you drive on the highway / freeway get off of the highway / freeway & back on, repeat. You want to avoid a consistent throttle when treating with SeaFoam.

I don't have that hose you used on my vehicle I don't believe, it's a 2018 GMC Terrain with the 2.0 LTG Turbo engine

I want to do this but im afraid of ruining my catalytic converter! I think i would just removed the intake and have the valves nut blasted!!! Still great video!!

Any ideas if you’ve had two engine misfires (1 year apart) from carbon buildup? 2013 pilot and the cost for cleaning is about the value of the car. I’m worried I’d damage the catalytic converter as you mentioned but would hate to call it quits on her so soon & trade her in.

So you're telling me that you can litterally disconnect the hose from the PCV valve and spray dirrectly into that hose on the TDI engine and that should do the trick? I got the GDI cleaner by LUCAS and I wanna do this, but I don't wanna have to dissasseble a bunch of stuff and I dont have much tool at home :/

Without evidence of cleaner valves/intake tract this is all just speculation.

I live in SoCal. If I do this an attempt to drive around with smoke billowing out, the CHP will hand me a ticket from hell, and maybe impound my car.

Question?? This might be a dumb ? I'm a 2013 KIA owner with GDI. I had no clue why I was getting such terrible gas mileage, (16 city/22 highway) The amount of money I have wasted is insane. I recall one misfire. Didn't know what it was till now. It really seems to run well fortunately. I'm at 90K miles now, owned it since 11K, and never even knew to clean the intake valves. It's too late to try this method of removal (with SeaFoam) due to likely destroying the catalytic converter. But...what if I temporarily open the exhaust bypassing the catalytic converter just to do this, one time?? Then next time I do this (every 10k miles) it shouldn't be an issue running the carbon through it. Does this sound logical? Anyone??

Seafoam is completely useless, it doesnt dissoöve carbon buildup at all! there are way better products

Where does the loose carbon go?

Does this actually work??? Proof is in the pudding. A borescope video would show definitively whether it does or doesn't.

Have you looked at the valves to check for the efectiveness?

Does the loose carbon deposits go past the cats and out the exhaust?

Thank you for this my friend!!!

Carbon gets to cat converter. $3k. GDI engine sucks !

At last a good video !!!

How do you know it worked? Have you looked at your valves?

It only “works” if you show a Boroscope view of the intake valves…

Some videos show that these things may help but don’t really “work”
As in, it can be a bit of a preventative… but once there is carbon, it won’t get rid of it.

Also the smoke after using Seafoam isn’t anything to do with carbon. It’s the solution that’s used, someone proved this on a new engine and the other products such as CRC, Liquimoly etc don’t have any smoke.

I added an oil catch can on my PCV hose to help even more.

Doesn't work

Install a oil catch can
