after reading up on the build up on intake valves with these older direct injected Ecoboost 3.5’s and nobody In my area doing the job, I decided to bite the bullet and buy a walnut blaster and am going to clean my intake valves tomorrow on my 2016 F150 with 82k miles .I’ve been trying to find a write up on the job and haven’t found a good one yet so I guess I’ll take some pics of the process start to finish and post it up, maybe I can get some North Florida/South Georgia folks together and help me pay for this thing and clean some valves

Turned out great. I really expected there to be more on them though.
I did as well, they were not as bad As I figured they would be with 80k miles on the clock
I was pleasantly surprised with how little gunked up they were...
Makes me wonder on mine 2013 with 230000 miles still runs good
I GUARANTEE if you had the service done you’ll notice a difference. Over time performance does slowly degrade with interference of carbon buildup that becomes progressively worse. I feel we become blind to the minute power robbers. I felt my truck was good too, at 185k’ish before having it done.
However, when I pulled out the shop the difference was very noticeable. Now at 203k’ish I still feel like it’s pulling good. But, nonetheless, that stuff is building it’s way back up little by little I’m sure.
I’m sure ur truck is fine, but have the service done definitely can’t hurt it. Pretty sure you don’t believe there’s not an excess of carbon on the ur valves that shouldn’t be there, right? Just get it knocked off BEFORE it becomes a problem at the absolute worst possible time.
EcoBeast3, that is why I keep logs and Draggy performance runs for comparison. While I do not have a "fast" truck I know how it performed since purchase in comparison documentation so far thru it's life. My truck is not that old with 65000 miles on it but it is as quick as anytime I have owned it, measure in several ways. KM
Well 600 miles after doing the intake valves and I just filled up and saw an improvement of almost 1.5 mpg and have felt a smoother idle immediately , so I guess for me it was worth it. I don’t like waiting for something to go wrong to address it so I saw this as maintenance and I’m good with that.
Gotcha… that’s an accurate way to keep of it’s performance. Wish I was as detailed as that. I just use senses; eyes, ears, nose, and seat of my pants for vibrations. Not as scientific as your method, but seems to be working.
And yes, your truck is just a baby at 65k miles. I remember those days. She’s got approximately 211k on her now. As long as we do what we’re supposed to do they tend to stay around for us a bit longer.
Hmmm… thinking about your data logging. Wish I’d done that before all the modding. I’d have a better account of my mods and tuning. Bummer…
I reused the factory intake gaskets, nothing wrong with them , sealed just fine with no issues
now as far as tool go , I spent around $400 ish for the walnut blaster, some walnut media and the 3.5 vacuum attachment on eBay .
Exactly what I’ve been saying each time I defend my reasoning for getting my valves walnut blasted.
