Hmm I hope that isn't the case.

Has anyone else noticed a gas smell in their catch cans?

Mine stinks but not like gas. Min is more acidic smelling. Also, would think DI on the ecoboost would be less likely to leak.

Who knows? This thread is interestinghttps://www.f150forum.com/f70/broken-timing-chains-2011-ecoboosts-242220/

Try that again. who knows?https://www.f150forum.com/f70/broken...boosts-242220/
I guess as more and more automakers introduce these type of engines we will learn more and possibly see changes to prolong engine life for all engine types especially the DI ones as that seems to be where Technology has turned.

The crud my cans are catching smells of gas also but it doesn't catch on fire with a lighter.

Watch your oil level and get an oil analysis if you feel there is a high level of gas in the oil.

So, after reading a lot of posts (and there are A LOT of them) about catch cans, I have been wondering something. It seems that in the winter the catch can pulls a ton of water out of the PCV system. I know my questions are gonna be almost commonsense.

Without a catch can installed, does all of that water just get "burned" off?.....where does it go? If it does just go straight into the intake valves, then wouldn't that hurt performance (mpg) a good amount??

I love my catch can. I've got the 5.0.

I emptied it on Saturday. Probably a 1/2 cup of tan oily fluid in there. Not as thin or watery as seen above.

Glad my Coyote did not have to ingest that crap.

Most of the crud gets pulled through the driver side valve cover, through the left turbo, blown into the CAC where some of it condenses back into water,oil, fuel mixture. The some of the fuel and some of the water will evaporate as the air moves through the CAC. Some of this mixture will be picked up and blown into the intake plenum, next stop is the valves and combustion chamber. The thicker, heavier stuff will stay in the CAC, this is the snot you see.

The PCV line from the passenger valve cover to the intake plenum also evacuates the crank case vapors but only when you are not making boost. Same vapors as above but really no chance to condense and pool, still bad for the valves and performance in general.

200 miles- strong smell of gasoline.
