I want to protect my vehicle for the future. I've heard you talk of catch cans and watched YouTube videos on them. My ecoboost does not have dual injection.
The problem is that all the catch can videos are sponsored by whatever can they are trying to sell, so I certainly can't take their word for it.
A catch can would also probably void my bumper to bumper, which will last 3 years (I'm a low mileage driver).
How do I protect my injectors from carbon buildup?
You have a GDI engine (with no port injection) so yes a catch can is definitely a good idea to mitigate carbon buildup on the back of your intake valves. Realize however if you need warranty work (for example something related to the engine) and you show up to the dealer with a catch can installed they can deny a warranty claim.
It’s not the injectors that need protection, it’s the valves.
I'm a big fan of catch cans. PCV valves aren't perfect. They let a little oil pass by them. You don't have to believe the companies. Just look at all the tests on youtube and how much oil they collect. If that hadn't been there, all of that oil would have been sucked in the intake and some of it would have caked up on the valves. Since no gasoline is being sprayed on them because of gdi, they wont get cleaned. Regarding your warranty, they really shouldn't void it for just a catch can because it really has no effect on anything else. But if they do void it for that, I would just take it off temporarily to go to the dealer and then put it back on when your home. How are they gonna know? And besides, its usually pretty easy to take it off and I'm assuming your not going to the dealer everyday. I know the ford ecoboosts aren't as bad as the VW's when it comes to valve dirtiness but I would still put one on if I were you. Just my opinion.
Again, thanks everyone for your honest input. I do appreciate your time!
