Prevent Carbon Deposits in Your Direct Injection Engine!

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

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.

Thank you for this my friend!!!

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.

At last a good video !!!

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.

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.

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.

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

Do a before and after

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

Where does the loose carbon go?

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 :/

Install a oil catch can

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.

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

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.

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??

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