Avoid induction cleaning on ecoboost engines
I thought this may interest people on the list. Apparently ecoboost engines are getting a lot of carbon build up and people are doing something called induction cleaning (I've never heard of it) that ...

Even the halo sporting Honda Accord suffers from carbon buildup in their EGR valves. There's a TSB on it. If it can happen to a Honda (hear the angels sing!) it can happen to any of them.
The problem with the EB is not carbon on the EGR valves, it's carbon on the intake valves. A much more serious and difficult problem to correct.
A quick Google search indicates this isn't limited to the Ecoboost engine at all. My '95 and '98 Cummins engines vented their PCV to the atmosphere through a down tube rather than suck it back into the intake like the newer ones do. I did this on my Harley as the PCV fed oil mist into the air cleaner and carburetor. Difference being gas vapor helped keep the intake valves clean. I wonder if venting the Ecoboost to the ground would keep the valves cleaner.
I'm sure it would but not only would dumping it on the ground be a messy EPA issue, it would also be a problem because the engine needs EGR to help cool combustion and keep tail pipe emissions down.
On a turbo gas engine like the EB, getting rid of EGR would result in not only high emissions, it would also result in pinging.
EGR valves have got to be one of the worst inventions the industry ever came up with. They eventually cause problems in just about every engine.
Bypassing the PCV wouldn't alter EGR function. Venting the PCV makes a drop every now and then. It's not a mess at all. On my two Cummins Rams that vented to the atmosphere with a down tube, I tie-wrapped a pill bottle to the tube and emptied it every once in a while. Very little oil was is it. The Harley drips a drop every once in a while too. The only noticeable difference was when I used Rotella. Boy did it stink when it was running.
