Hey guys, I was wondering if any of you have added a catch can to your ecoboost engines and if you think it makes an impactful difference.

Waste of money. The number of ecoboost owners out there with zero issues outweighs the number of owners who added a catch can.

I'm not a "do a search" kind of guy, but there are a lot of threads on this if you want to get more opinions and make your own decision.

I came to the conclusion that I didn't need one.

Without a catch can your engine will explode with no warning because of EGR vapors that the engines have been engineered to deal with for a few decades now.

With a catch can your warranty will be void forever and ever and Ford will refuse to honor it, so when your heated seats fail and your rear window blows apart, Ford won't do nuffin about it.

Some even go so far as to say it "catches" any synthetic washer fluid from getting away.

I do however have one on my 3.7 Mustang as well as my 5.0 F150. They do "catch" some oil, but as to any "performance" enhancement on a daily driver. I don't think there is any.

Well, considering that a PCV system's design and function is to evacuate crankcase fumes, and recycle them back into the intake system to prevent them from being vented into the atmosphere, it does what it is supposed to do.

Now here is the thing about catch cans. Why do you see water and oil being collected? Because the added length of hose, and the vortex created in the device cool and condense the vapors. By design. When you lengthen the distance between the crankcase exhaust port, to the intake, yes you will cool the vapors and they will condense. Some smart Snakeoil cookie figure this out and found that by doing so, can sell these things by telling people, Look how much goes into your intake!

DUH, thats what it is supposed to do, however, with the engineered design of the PVC system, the vapors are hot, and will not condense, but be combusted in the cylinders instead.

Thanks guys, I am not going to get one. Why would Ford not build a catch can system stock if they were so important? Probably because they don't really make a difference. I have 46,000 on my 2.7 ecoboost. Haven't needed one yet.
