I use a long 1" wide nylon brush and Amsoil Power Foam. The foam fills the intake runners and cleans those off as well. Melts all of it like butter. Looks BRAND new when I am done.
Instead of using paper towels, I use a shop vac to siphon the fluid while spraying it with a cleaner or a bottle of compressed air. That worked really well.
Most aerosol cleaners are flammable so I don't feel good having them near an electric motor. I'm sure it works good but I personally don't like the risks associated with it.
This is a good point. Buy long zipties so you don't have to get as close as I did. Ideally the chuck would never touch the intake but I'm sure there were a couple of times it accidently did. I did not notice any damage if I did touch it to the intake.
It is not a car I drive regularly but if the valves get dirty enough they can cause performance issues. Generally with this level of carbon you would only see a slight decrease in power at wide open throttle. I personally didn't notice any difference.
There are no injectors in the intake manifold which is why the gas doesn’t wash the valves but just about every engine in existence operates with an intake manifold.
You could probably do this much chepaer with a STP valve cleaner kit. you do this very 50k miles and that along with good oil and fuel treatment , you should have no issues.
Fuel treatment does nothing for this issue. Anybody who says otherwise is probably selling something. The STP valve cleaner kit may work (I haven’t tried it) but it does cost more than what I do in this video. If you have any sort of drill this technique only costs about $7 and on the hondas you have to do most of this disassembly to adjust the valves anyway
@@clb_52 as long as you have oil being sprayed and baked onto a hot valve with nothing to rinse it off you WILL have this problem eventually. OIl change interval changes and different formulations are just ways for the manufacturer to dodge liability and have not been proven to fix the issue
Most people have a different idea of what is cheap. I would guess that this would cost most people 200-500 at a shop. However you can accomplish what's in this video for less than $50 and you get to keep the tools. There isn't really much risk involved as long as you make sure the valves are closed on the cylinder you're working on. The reason why I did this "the shade tree" way is because I don't trust shops to do the job well and I didn't want to invest money in a media blaster that I have no other use for.

Tip - slide a long section of clear plastic tubing over the bundle of zip-ties with a zip-tie strapped at the end.
I like that idea over the multiple zip ties holding the bundle. Next time I do a valve adjustment I’ll give it a try.
Banging that drill chuck against the intake scared the hell out of me

EGR on direct injection is a bloody stupid thing.
How many miles were on this fit?
about 147000 miles
@@thehondafitguythat pretty clean for that mileage...
Any difference in performance??

I thought direct injection never had an intake manifold
There are no injectors in the intake manifold which is why the gas doesn’t wash the valves but just about every engine in existence operates with an intake manifold.

I didn't know Ernie from Sesame Street worked on cars.
Burt used to help but then there was “the accident”
Long oil change intervals is mostly responsible for this problem with modern engines
Long oil change intervals don't help but the lack of port injection is what causes this problem on direct injected engines.
@@thehondafitguy GF-6 oil is formulated that problem but long oil change intervals defeat the purpose

If it’s GDI, it’s by design (flaw). No gas spritz on the intake. Don’t waste money on gas additives for valve cleaning.
Many are now going to dual injectors 1 DI and 1 Port. To help with this issue
Take it to the garage. It’s cheap. Don’t risk it shade tree mechanics.

It’s such a simple job lol dudes that can’t even turn a wrench would make such statements
500 here too. Walnuts blasting though...
Don’t buy a GDI engine unless it’s also port injected as well …
