I thought Sea-Foam was a NO-NO in direct injected Turbo engines, please correct me if I'm mistaken. I heard the crap released (specifically from behind the unwashed intake valves) gets into the turbo and causes problems, no more investigation than that yet.

I heard that too, thats why i was curious if anyone has done it and made a video. I seafoamed my previous cars before without any problem. The reason i wanted to seafoam my ex-t is mainly because of the noisy lifters.

You are correct! Fuel additives like that, especially when used as an intake or fog style, rape a turbocharged direct injected motor. See YouTube for a brilliant Ford techs explanation of what cleaners do to these motors. FordTechMakuloco.

While it covers their ecoboost platform, the base idea is the same.

1. Knocking carbon deposits loose that don't burn completely have the potential to damage fins on the turbine wheel.

2. Increase of chemical contents can wash the bearings in the turbo, increasing heat exponentially, and basically burning it up from the inside out.



The OP has a naturally aspirated engine on his EX model, so that doesn't apply there. But, for turbo owners,

do not do this under any circumstances!!!!!

OP has an EX-T.

Also, @buset46, noisy lifters are a characteristic of any DI engine. There's nothing you can do about it.
Yeah, i know DI engines get noisy, but it still bugs the hell outta me, coming from a 9th gen which just purrs. LoL guess i will just have to live with it.

I would use a product better formulated for GDI. Something like this:
Honda Civic 10th gen Seafoam 3



There is A LOT of misinformation about what these cleaners can and cannot do. In port injection motors, we'd traditionally add through the brake booster or fuel line. However, in Direct Injection motors, this doesn't work due to the placement of the injectors. GDI cleaners MUST be atomized through the throttle body. Otherwise the chemical never touches the intake valves. Even then, their cleaning ability is greatly reduced.

As mentioned above, these types of procedures really aren't needed until after 30K. Perhaps even longer with Honda. In other platforms like VW and BMW, the service manual specifies removing the Intake Manifold and blasting walnut media to the IM/valves to remove the carbon buildup. Using a GDI cleaner every so often can help minimize the expected accumulation. Though it's not a substitute for walnut media.

Using cleaning agents on a cold DI motor is a fool's errand. The key mechanism on DI is HEAT.

That is only true in extreme cases where the engine has been neglected for an extended period of time, or is subject to a high amount of carbon buildup through poor design. When we get to that point, the only fix is a chemical soak followed by walnut media. In typical applications, say every 60K, the buildup is softened to an oily residue and wiped off (in small amounts) through normal operation where it's subsequently burned in the cylinders. Very similar to the way it accumulates over time. Anything that passes beyond that point is nothing more than harmless vapor/gas.

It remains to be seen as to how Honda is impacted by deposits, which is influenced mainly by poor quality fuel and long oil change intervals. But I suspect that the average Joe will maintain this car better than most other DI platforms (thanks in part to the maintenance minder).

This would be the right type of Seafoam applicator to use in DI:
