[@cosmiclawnmower9818]

Thanks for sharing. Just goes to show why GDI coupled with a standard PCV system is a major design flaw in modern engines that are built this way. Any engine that uses GDI should come from the factory with an oil catch can or include redundant port injectors to keep the valves clean.

[@nerd1000ify]

No strict need for a catch can but you do need a good air/oil separator in the PCV system, to get the oil mist out of the blowby and send it back to the sump. A catch can is just another secondary air/oil separator, retrofitted because the OEM one is inadequate (or absent).

[@shaunvalencia2644]

Underrated comment, lol

[@stephenbloom2545]

That’s all due to insufficient filtration on the oil filter. These turbo charged direct engines require a 20 mic filter filtration, anything larger than that you see this happening. Try switching to the Amsoil filter with a good synthetic oil and you don’t have these issues. I use Amsoil signature series oil and I have 441,000 miles on my f150 3.5 ecoboost and I’ve never had these types of issues. I used a 40 mic filter when I first got it and the PCV fluid was black and gritty, I changed over to a 20 mic filter and the PCV fluid turned to a light brown fluid that feels like a good oil. The fluid will burn in the combustion chamber the black gritty stuff doesn’t.

[@ThePhotographyHobbyist]

So far no issues with my 2014 F150 with a 3.5 ecoboost. I do rev the engine fairly often, not abusing it, but not driving like grandpa either. Also using Pennzoil platinum synthetic oil. I also might have a tiny hole at the bottom of my intercooler to allow some of that gunk to blow out on its own without losing any boost of course, I say I “might” have a tiny hole. ;) ;)

[@rustybrown771]

Good trick I use is get the car to normal running temp then start tearing the I take manifold off. By the time you have the intake manifold off the engine cools enough and those deposits come off much easier when warm.

[@RK-kn1ud]

If I were doing all this work to clean the intake valves every couple thousand miles, I'd probably just fabricate in some secondary fuel injectors to wash the valves down 1-2 times per drive cycle. Having to do this more than once (or at all) is insane.

[@thatguy3481]

I heard that some regular hard throttle can keep it from building up too bad. It's the easy city driving or mild highway use that causes a lot of build up. I'm nearing 100k on my F-150 and it's OK. Nearing 80k on the Escape that the wife putts around town in and I think it's going to look more like this video. It vibrates at 8dle a bit. But no code yet.

I accelerate hard in it sometimes and drive it on the mountains so it probably heat cycles enough to cook that carbon off. It's a 2015. Our escape is a 2014.

Did this on my 14 focus st. Before that it had a few misfires and what not. The carbon build up was pretty bad with 82k. I used crc and let it soak for about an hr on each valve while it was fully submerged. Then scrub with a hard thin brush. Then I would use a small vacuum attachment on my shop vac and suck it up. Repeat until it was smooth. Then installed catch cans 😁. She definitely idles better and has less misfires. Worth the troubles. I'd tape off the other valves that are already clean to keep them from getting debris inside from the dirty ones. great vid and info. Wish I found this sooner.

[@1Bohimyme]

i have a carbon vac machine but with the intake desigs of todays cars the machine is not sufficent in cleaning the carbon off the valves. Renoving the intake on todays down draft intakes is the best way to get a good scrub on the intake valves. Also allows you to clean all the oil buildup from the pcv system in the intake by removal. Sea foam works good for me.

@@markkoranjr6426 Yep, let's scrub our valves every 10-20k miles, what fun! I'll add, I've seen plenty of carboned intake valves on even carbed engines (wet intake) to realize a dry intake valve is gonna be a problem. They had to know, yet did it anyway.

[@drivenbydemons6537]

I've been asking around the forums but can't really get a straight answer. Will occasional water or water meth injection keep this from getting out of control? I'm thinking using a pump type sprayer or something while highway driving before I do an oil change. I know hydrolocking is a danger but i'm talking an atomized spray tip.

[@markconley9279]

Is there a blaster, maybe walnut shell, that can blast and vacuum each port at a time? Something that doesn’t let the media get all over the place.

[@benwilliams2260]

Do you have any fiesta videos? Where the heck is the tpms receiver located.

[@AStanton1966]

I put an oil catch can on my 2017 Silverado 5.3 and I can't believe the amount of blow by it catches. You can thank the EPA for choking our engines in these pollutants and making them run worse. I just bought a new 2020 Mustang GT. I got 2 check engines lights already with less than 1,800 miles on it. One for the purge valve and one for the evap canister. More pollution related BS.

[@jimbeam4535]

Does this apply to the 3.5L v6 ecoboost? I’ve been thinking about doing mine and installing a catch can. 120k on the clock, runs great but figured it’s probably pretty built up.

[@thatguy3481]

Look on line , you can order a small Borescope to plug into your phone. Can have a look yourself. they are surprisingly cheap. My F150 3.5 has 150k miles an after scoping it was time. Just a warning the back Cylinders at the fire wall require some stretching an creativity.. But I believe after 2015ish 2nd injectors were put in to correct the issue.

[@gianmariavolonte4315]

Depends on the year of the vehicle. Port injection was added in 2017 models in addition to the direct injection on the 3.5 ecoboost.

[@LS-zr8py]

@@thatguy3481 2018 2nd injectors put in for f150

[@thatguy3481]

Thanks for the info 👍

Have you seen it drop the compression

[@crashdude09]

Do you have a guide cleaning the values for 2017 ford Fiesta st?

[@thomwood8768]

I know this has nothing to do with the ECO boost but I have a problem I cannot figure out and thought you might be able to help. ok. So here is my dilemma. I have a 2000 GT with Hydro-boost, of course. You probably already know where I am heading with this but wait, there is a twist. I put in a new steering rack, all Teflon seals have been replaced all the way up to the hydroboost manifold, there is a brand new steering pump as well and there are no fluid leaks anywhere what so sever. I have done the ridiculous 90 sets of turning the wheel from lock to lock along with pumping the brakes in between each set with the car off and front end raised off the ground, my forearms are huge now.!!!! It drank only a little bit of fluid and not much more. I tried running the car out of frustration and that did not help either. I am still getting a lot of whirring from the steering pump and the brakes still go to the floor while whining. I am so frustrated with this and have no other clue as to what it could be, maybe a bad hydroboost pump? any suggestions as to how to fix this crazy problem? Could there be an air leak somewhere that won't show signs of fluid leakage? I also forgot to mention I hear a gurgle coming from the steering rack when I turn left all the way to the lock while the car is ignition off. Driving me nuts here, any suggestions?

[@johnleinen9409]

My 03 focus SE just turned 242000 miles and runs perfect! None of this DI b.s .

[@Camj27]

What’s your thoughts on walnut blasting the valves?

[@jamesmcintire3800]

I just purchased a used 2017 Edge 2.0 with 78,000 miles. How often should this be done?

[@rnius]

Do the new oils really help? Thanks love your vids.

[@FordTechMakuloco]

Yes they do

[@fordman6406]

Use Full Synthetic Engine oil.

[@dfls5069]

Is it just fuel being burned up in the cylinder? Or does oil flow in there as well?

[@Bacongrease00]

My wife’s 2013 escape 2.0 ecoboost idles rough but has no misfire count. 138,000 miles. Gets good MPG and runs fine other than a rough idle. Replaced motor mounts. Could this be a carbon issue? Uses no coolant

[@PRO4XKEV]

In the Subaru world, walnut shell blasting works well.

[@derjoh1986]

Get this professionally done, most people here watching this don't have the time, tools nor the patience to do all of this stuff.

[@terrykeenan3118]

Whats your opinion on catch cans for the oily pcv recirculation causing this?

[@alphawolfadventures1470]

He has a vid and recommends rx can which he put on his ecoboost I believe

[@ammar1859]

What about the V6 mustang 2017 is it the same ?

[@davide.s.9880]

So if it can happen at any mileage what use is this maintenance cleaning you talked about? I was going to ask if I ran or had my mechanic run the cleaning every forty thousand would that be good? Sounds like every twenty thousand I might just make it under the finish line.

[@FordTechMakuloco]

My explorer was an extreme case I would say every 40-60k would keep any drivability concerns at bay.

[@marksill8020]

Maybe I missed it, but what can you do, if the engine is new, to prevent this from happening? Oil catch can?

[@macknight1881]

My local Ford dealer told me this was not necessary for optimal engine performance

[@randellgribben9772]

i also work as a tech.. classic italian cars, heres a question.. to help stop the carbon build up of course use a oil catch can( my 2014 2.0 ford fusion is off the factory warrenty.. ) but instead of routing the hose from the catch can into the intake manifold.. route that hose back into the bottom ( intake side ) ( close the port on the intake manifold, of course ) of the engine air cleaner box.. this below the air filter and after the bronze micron filter in my oil catch can..should remove almost all the oil vapours.. that are in the system. thanks for the reply

[@michael_house]

Thanks for the video. I've seen an older video where you used the walnut blasting method. Now you are back to manually cleaning. Is there any particular reason for that?

[@charliep5139]

Thanks for the video! At first I thought about blaming car makers that don't do some type of port injection for making a product with what I see is such an obvious design flaw. I'm sure they see it as another way for the dealer to make money either by the service to clean or a new car or engine if it gets bad enough. It's crazy that they've known about this for close to a decade now and theynjust don't care. But I actually blame the consumers out there. I have zero sympathy for people that willingly buy cars that are direct injection only. If consumers cared more about how a car is actually made instead of caring about how it looks and if it has all the latest, fancy electronic bells and whistles that will get all buggy and stop working in a few years anyways then car makers would stop making these type of engines. But most Americans probably don't care about getting a quality car that will last them forever and would rather be in debt forever getting a constant stream of crappy cars every few years.
