I keep reading that the eco-boost engines require more maintenance, what kind of extra maintenance do they require?
Thanks

that's just a myth perpetrated by a few 5.0 fanboys.
yes, you CAN (should?) do more preventive maintenance than recommended, just like any other engine. In reality, the EB was designed to be owned by random schmucks like me. Drive it, take it to the dealer every 5,000 miles, rinse and repeat, end of story.
it doesn't REQUIRE extra maintenance. Would it hurt to change the spark plugs every 20k miles?no. Add a catch can? probably not. is it required to get 100+k miles out of it? no.

MAP sensors every oil change too..clean em..takes 5 min for all 3.

Thanks for the info, I tried to find the answer but didn't see any extra required maintenance.

There could and should probably be a whole thread devoted to debunking turbo related myths... There is no added maintenance for modern turbocharged engines! Stay true to recommended service intervals and the turbocharged engine will last every bit as long as its normally aspirated counterpart.

If you run a tune, up the frequency slightly on oil changes, plugs and possibly coils. Also keep an eye on Temps, as heat tends to be the biggest threat with turbocharged engines. MAF sensors only require cleaning if you're getting significant oil accumulation in the intake track... and truth be told it takes a lot to kill MAFs! I'd be more concerned with intake valves caking if you have a lot of oil in intake track. It appears to be somewhat common on pre-2017 3.5 EBs, but not so much on the 2.7 EB. A catch can on the pre-2017 3.5 could prolong the need for intake valve cleaning significantly, but I have yet to see pics horror stories even on 3.5s with over 100k. My N54 Bimmer needed valve cleaning at 40k for reference...

As an aside, the new 2017 3.5 EB eliminated any possibility of caked intake valves by using dual injection (direct and port) to wash away intake deposits before they accumulate. Probably a good move even if it never proves to be a problem on the pre-2017 3.5 EBS.

I have all of 800 miles on my 2.7 EB and peeked at my intake tract out of curiosity... bone dry!

I'm not a "motor guy" but am pretty handy. And I just recently came across all this talk about possible issues with the ecoboost and needing a catch can....yadda yadda yadda. I have. 2017 2.7 EB and would like to know where I would check to see if my system is "bone dry". I'm not sure what the intake tract is. Any help would be greatly appreciated. Thanks. I'd rather. It have to install some catch can and just periodically check something.
