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
