Is decarbonizing my valves as serious as the Ford guy makes it sound?

The next time someone tells you something like that, tell them they can do it only if they will change your blinker fluid for free.

They want $329.99+Tax from you so they can put a $3.00 bottle of injector cleaner in your fuel tank!
Just curious as to what service you were getting done that required them to inspect your combustion chamber? I wouldn't be surprised if he also recommended the engine shampoo & flux capacitor tune. Originally Posted by MarcellusWalluz

Does your Mustang have the EcoBoost engine? Depending on the year, you may have the single port direct fuel injection. The design of that engine does lend itself to buildup of carbon deposits on the back of the intake valves. The 2017 and up EcoBoost are switching to multi-port direct fuel injection to alleviate the problem.


Think of the carbon buildup like plaque buildup on your teeth. They are just going to scrape (decarbonize) the plaque off.

You can buy a bottle of techron and add that to your tank every 1000 miles.

i didn't read any of the bull shit in this thread.

but you'd already know the details/numbers on your situation had you done that dry and wet compression test i told you about months ago.

my box is full or I'd message you my hobby number.

I'd love to explain some of this stuff to you personally but i know how much i turn you on and you won't be able to focus on my wrist pin and connecting rod discussion while you can't stop thinking about blowing my head gasket.

edit: hey maybe look up my hobby phone number in the trick book and txt me.

edit 2: if you've never changed the spark plugs in that engine, do not do so until you talk to me....or do the compression test. because you pull the plugs for that.

^^Brooke, sounds like he wants his head blown...
GS, just fuckin with ya...

i knew there was an extended sexual metaphor somewhere in here...

Next she'll want me to polish her ports.

^^ikr...

It doesn’t hurt to clean them after high mileage, but not necessary. Maybe do an Italian tune up. However if it’s a direct injected engine, then it is necessary.

Any one ever used Restore engine oil additive on a 5.0L Coyote engine? Are there any issues with the VVT?

The Seafoam sometimes works very well. It's cheap and worth a try.
The Marvel Mystery product has been around as long as I can remember and lots of people have sworn by it. It's mostly just mineral oil and solvent.

Easy way is to use top tier fuel and leave the cheap stuff for the minivan crowd.
It is always good to run some fuel infector cleaner depending on how much you drive. the longer a car sits the more deposits can accumulate in the system. If premium fuel is recommended for your car, use it. This generally is most high performancehigh compression engines that are either built that way, have a turbo charger or a super charger. If not top tier regular is fine.

I have a Tahoe with over 230,000 miles and have never decarboned my valves by any method other than fuel additives. mechanic says the numbers check out like a new engine. I once got way over 140,000 miles out of a set of Michelins on this SUV. Getting a lot of miles out of brakes and other components is all in the way you drive along with the quality of the components. If you want to keep a vehicle in good operating condition, maintain it it to the highest standards but don't wate money.

That Ford whore often comes in here blowing questions down our square bore Holleys....then vanishes like a leaky valve seal puff of blue smoke after startup.

Brooke I work in a high end luxury dealership and depending on how the injector set up is on your engine the valves could have carbon on them. I'm a master technician by the way. All the manufacturers that are using direct injection only are having carbon issues. I've rebuilt hundreds of engines with this issue. Some had fairly low mileage. Just try and find a shop that sells BG products. They have a product called 44k that works extremely well. Just PM me if you have any questions.

Look up " seafoam" engine cleaner on YouTube. I have a couple of friends that are honest mechanics and they told me about the stuff. Then I saw a Harley dealership mechanic using it on his older bike. out of curiosity I ran it through my dads 20+ yr old riding mower. Have to say if I drove a gasser instead of diesel I'd definitely use the stuff. Many before and after homemade videos on YouTube. The stuff is impressive
