Ford Ecoboost Engine Carbon Deposits: What You Need to Know

Here is my latest video on the Ecoboost Engines and carbon buildup. I quickly sum up what I was trying to say in my popular video- New Warning to All Ecoboost Owners. I go over what we are seeing at the dealers and what you can do to prevent any excess buildup of carbon as well as the latest information from Ford. This one video should answer most if not all of your questions pertaining to this issue.

*****Note- I mention a catch can WILL void your warranty if added, I want to be more clear on this and state that a Catch Can MAY void your warranty. It is all up to your servicing Dealer and the Ford Field Reps on a case by case basis.******

Thanks for the info again. Does ford have plans to sell or provide catch cans as a TSB for EB vehicles?

just a theory. i have a 2014 fusion titanium. i really don't want to wait until its carboned up real bad to try and fix it. i run only chevron high octane fuel. and the mobile 1 full synthetic, extended performance oil. and change it every 3500 miles. did my first oil change at 1500 miles...ish. I'm a mechanic at a Suzuki, KIA, Mitsubishi dealership, and have access to all the extra cleaning chemicals i could need. i know there isn't a ford approved method yet. but what i'm thinking. is to avoid the large chuck of carbon coming loose problem why not perform a induction service more often. to prevent any substantial build up. and to prevent a washing of the bearings. only do small portion of the chemical. so just every so often spray a 1/4 of what would normally be used to keep up on the cleaning instead of a big wash of the stuff all at once. and lastly a concern about over heating the turbo or cat. perform this on a cold engine, before anything warms up too much you are finished. then rev up and blow out the cat before the stuff loads up in there while it warms up to the point of causing any heat issues. I haven't done this yet. but am seriously considering it as i don't like the idea of trying to take care of my engine only to have to put a reman head on it every so often. i want and need the engine to stay original. and feel that's achievable with this method. its a turbo motor, i get it. but a little extra care and i think we can get a long life out of them. also i did notice a lot of oil residue in the pcv line, and that is probably the largest contributor to the build up.

I didn't watch the video in the original post, but this is a major issue with any direct injection motor. I owned a 2007 GTi and found out how much of a pain this build up can be. Only way to clean it is to take off the intake manifold and clean the ports. A catch can setup would be the best setup to help prevent the effects of carbon build up. You'll never see a catch can on a factory car due to it not being emissions friendly.

Hi arg. No...you can not squirt things into the intake to try and clean the valves. Any loosened deposits will find their way into the turbo housing and damage the turbos, seals etc.

Currently, the only acceptable way is to remove the intake manifold and media blast the valves, or manually clean them some other way.

Good luck.

lots of turbo owners use water/ methanol injection to boost. cool the intake charge....i cannot see big or little chunks comming off... a slow ' wetting' of any if i have any would keep the intake valves..i have a endo scope.. were would be a good location to install the scope,, to look inside?

Hi arg. You were not asking about cooling the intake charge, you were asking about cleaning dirty valves. Those are two very different situations.

Anything that loosens/cleans the deposits off dirty valves will send the loosened deposits into the turbo housing.

Methanol injection can help keep things cleaner if you are starting with a new/clean engine. An engine like yours, with 143,000 miles, with probable existing deposits, is an entirely different story.

I will leave further explanations to the OP (makuloco2000), since he is a tech and you will hopefully believe him.

Good luck with whatever you decide to do.
